cellular respiration
summary

Answers

Answer:

Cellular Respiration is a process in which the cell turns glucose into ATP ( adenosine triphosaphate ) which is the cells energy. ATP is when 3 phosphate groups break apart creating glucose and energy. There are two types of respiration ; Aerobic Respiration and Anaerobic Respiration. Aerobic Respiration requires oxygen and Anerobic doesn’t. Anaerobic Respiration creates a small amount of the cell’s energy and Aerobic Respiration creates most of the energy used to function.
         The first step of Cellular Respiration, regardless of whether it is aerobic on anaerobic, is when the glucose breaks down into a smaller molecule called pyruvate. Pyruvate consists 3 carbon atoms, 3 hydogen atoms, and 3 oxygen atoms. Glucose consists of 6 carbon atoms, 12 hydrogen atoms, 6 oxygen atoms. 1 glucose can make 2 pyruvate.
         If oxygen is not present after pyruvate is created, the molecule undergoes the first step of anaerobic respiration, which is fermentation. Fermentation is when pyruvate goes though a specific process and creates a small amount of ATP and a byproduct. The byproduct for animals is Lactic acid. The byproduct for bacteria and yeast is ethanol. This is Anaerobic Respiration.

         If oxygen is present after pyruvate is created, it enters Aerobic Respirations. Pyruvate is transported to the matrix of the mitochondria, where it starts the Krebs Cycle also known as the ‘Citric Acid Cycle’. The Krebs Cycle was founded by Hans Krebs, a biologist, physician, and biochemist in 1937. The Krebs cycle turns pyruvate into high energy electrons.  These electron are then diffused throughout the mitochondria. Diffusion is when some goes from a higher concentration to a lower concentration. The process of diffusion of these electrons is called Chemiosmosis. Then those electrons are transported, by electron carriers to the ETC is the electron transport chain.  The ETC transports these electron to the last step of Aerobic Respiration which is ATP Synthase. ATP synthase is basically like a gate. The electrons travel through the gate, and they start to turn like a waterwheel. By rotating they create ATP, which is the whole reason Cellular Respiration takes place. Then the leftover oxygen and electrons are attracted to each other and they combine. They go though a cochair made of proteins. This chaos exists to transports these molecules. The proteins suck the energy from the molecules and then release hydrogen and carbon. Now the oxygen and hydrogen and carbon create water. The whole process of diffusion, chemiosmosis, ETC, ATP Synthase and the creation of water is called Oxidative Phosphorylation.
         This is Cellular Respiration.

When describing a community, a biologist would identify every

Answers

When describing a community, a biologist would identify every component or characteristic of a biological community.

A biological community refers to a group of different populations that inhabit a particular geographical area and interact with one another. Biologists would observe different aspects of a community, including the organisms’ ecological roles, population size, distribution, and diversity. In addition, a biologist would also consider the types of relationships between different organisms in the community, including competition, predation, mutualism, and parasitism.

In terms of population size and distribution, a biologist would examine the population density of each species in a community, as well as the spatial arrangement of organisms. This information is essential in understanding how the different populations interact with each other. For instance, organisms with higher population densities may compete for limited resources, such as food and water.

In terms of ecological roles, biologists would identify the trophic structure of a community. This involves understanding the flow of energy through different levels of the food chain, including producers, consumers, and decomposers. Biologists would also observe how different species play unique ecological roles, such as pollination or seed dispersal.

Overall, a biologist would consider every component and characteristic of a community when describing it. By doing so, they can gain a comprehensive understanding of how different species interact and function within a particular ecosystem.

inserting functional genes into diabetics to help them produce insulin
inserting functional genes into diabetics to help them produce insulin

directly delivering insulin into the cells of diabetics

inserting the human gene for insulin into bacteria

Answers

Biotechnology is a scientific application that has been used to improve insulin production for diabetics, scientists have used biotechnology to develop artificial insulin that can be produced in a lab by inserting the human gene for insulin into bacteria.

Insulin is the hormone that regulates blood glucose levels, and its deficiency in the body results in type 1 diabetes. Traditionally, insulin was derived from the pancreas of animals such as pigs, but due to their high cost and risk of allergic reactions.

The production of insulin by bacteria that have been genetically engineered with the human insulin gene is the most common method of producing human insulin. This approach allows for the mass production of human insulin and has significantly lowered its price. Insulin is produced by the bacteria as a precursor molecule that is then chemically modified into active human insulin by removing a small peptide sequence.

The insertion of functional genes into diabetics to help them produce insulin is another application of biotechnology in the management of diabetes. This involves the transfer of functional genes, typically those that produce insulin, into the cells of diabetics to compensate for the deficiency of the hormone.

Gene therapy has been a promising solution to the management of diabetes, but it is still in the experimental stage, and more research is needed to make it a viable option for patients. The delivery of insulin into the cells of diabetics can be done either directly or indirectly.

Indirect delivery involves the use of insulin analogs that are injected into the bloodstream, while direct delivery involves the use of insulin pumps that infuse insulin directly into the subcutaneous tissues. Both methods have been effective in the management of diabetes, and the choice of delivery method depends on the patient's preference and their ability to manage their condition effectively.

In conclusion, biotechnology has significantly improved the production of insulin for diabetics by allowing for the mass production of human insulin, the insertion of functional genes into diabetics to help them produce insulin, and the direct and indirect delivery of insulin into the cells of diabetics. These applications have not only lowered the cost of insulin but have also made it more accessible to patients with diabetes.

Please help! how does a cell control gene expression through transcription?

A. by preventing the production of mrna molecules

B. by preventing mrna from binding to ribosomes

C. by preventing the binding of amino acids

D. by changing how a protein is folded

Answers

Answer: A. by preventing the production of mRNA molecules

Explanation:

In order to control gene expression through transcription, a cell can regulate the production of mRNA molecules. This control is achieved through various mechanisms:

1. Cells can produce transcription factors that bind to specific DNA sequences called promoter regions. These transcription factors can either enhance or inhibit the binding of RNA polymerase, the enzyme responsible for transcribing DNA into mRNA. By controlling the availability and activity of transcription factors, the cell can regulate the initiation of transcription and thus control which genes are expressed.

2. The DNA in the cell is packaged into a complex called chromatin, which consists of DNA wrapped around histone proteins. The cell can modify the structure of chromatin through processes such as DNA methylation and histone modifications. These modifications can either promote or inhibit the accessibility of DNA to transcriptional machinery, thereby influencing gene expression.

3. Cells can use small RNA molecules, such as microRNAs (miRNAs) and small interfering RNAs (siRNAs), to regulate gene expression at the transcriptional level. These small RNAs can bind to mRNA molecules and prevent their translation into proteins or promote their degradation, leading to reduced expression of the corresponding genes.

While options B, C, and D are involved in other stages of gene expression or protein synthesis, they are not directly related to controlling gene expression through transcription. Therefore, the most accurate answer is option A, by preventing the production of mRNA molecules.

Why is the fossil record of clams more complete than that of spiders?

B. Spiders are too small to be preserved well.
C. Clams were more abundant throughout geologic time than spiders.
D. Spiders only recently evolved, so they are absent from the fossil record.

Answers

i believe A would be correct :)

Answer:

The best answer is A:

A. Clams have very hard shells, whereas spiders have soft shells that break down more easily.

Explanation:

Spiders are any of numerous predaceous arachnids of the order Araneae, most of which spin webs that serve as nests and as traps for prey.

Arachnids are any wingless, carnivorous arthropods of the class Arachnida, including spiders, scorpions, mites, ticks, and daddy-longlegs, having a body divided into two parts, the cephalothorax and the abdomen, and having eight appendages and no antennae.

The oldest fossils of spiders are 52 million years old.

Fossils are any remains, impression, or trace of a living thing of a former geologic age, as a skeleton, foot print, etc.  

For a fossil to form, the remains of an organism must become mineralized through a process of permineralization or through replacement of organic material by mineral deposits.

Clams have hard shells made of calcite, a mineral form of calcium carbonate. These shells are resistant to chemical and biological breakdown and can become fossilized relatively easily.

In contrast, spiders have soft exoskeletons made of chitin and proteins. These are susceptible to decay and decomposition, making spider fossils rare and incomplete in the fossil record. Their fossilization likely requires exceptional circumstances of rapid burial and mineralization.

Options B, C and D are not supported as the primary reason for the disparity in the fossil records of clams and spiders. Though spiders are small and possibly less abundant, some small arthropods do still appear as fossils. And spiders have been around for over 300 million years, so they are not newly evolved.

• The sources of acid deposition

• The chemical equations involved in acid deposition formation

• An explanation of the types of acid deposition

• A discussion of the effects of acid deposition

• A drawing that shows the sources, formation, and precipitation of acid deposition

Answers

Acid deposition, also known as acid rain or acid precipitation, refers to the deposition of acidic substances from the atmosphere onto the Earth's surface. It is primarily caused by emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) from human activities, particularly the burning of fossil fuels such as coal and oil in power plants, industrial processes, and vehicle emissions.

The chemical equations involved in acid deposition formation are as follows:

1. Formation of sulfuric acid (H2SO4):

SO2 (sulfur dioxide) + O2 (oxygen) + H2O (water) → H2SO4 (sulfuric acid)

2. Formation of nitric acid (HNO3):

NOx (nitrogen oxides) + OH (hydroxyl radical) → HNO3 (nitric acid)

Acid deposition can occur in two main forms: wet deposition and dry deposition.

1. Wet deposition: This occurs when acidic compounds in the atmosphere combine with water vapor to form acids that are then brought down to the Earth's surface through precipitation, such as rain, snow, sleet, or fog.

2. Dry deposition: In this form, acidic compounds settle directly onto the Earth's surface without the involvement of precipitation. These compounds can be in the form of gases, particles, or dust, which are deposited onto plants, buildings, soil, and water bodies.

The effects of acid deposition can be significant and wide-ranging:

1. Environmental impact: Acid deposition can acidify soil and bodies of water, leading to detrimental effects on aquatic ecosystems and plant life. It can harm fish, amphibians, and other aquatic organisms, as well as affect the pH levels and nutrient availability in soil, hindering plant growth.

2. Damage to infrastructure: Acidic substances in acid deposition can corrode and damage buildings, statues, bridges, and other structures made of materials such as limestone, marble, and metals.

3. Human health concerns: Acid deposition does not directly pose a significant health risk to humans. However, the pollutants that contribute to acid deposition, such as sulfur dioxide and nitrogen oxides, can contribute to respiratory problems and aggravate existing respiratory conditions in susceptible individuals.

Answers

The best explanation for why oyster larvae appear to struggle to survive in acidified seawater is the lack of appropriate food.

Acidified seawater has an abundance of hydrogen ions, which makes it difficult for organisms that depend on calcium carbonate to survive. Calcium carbonate is used by oyster larvae to build their shells. However, when hydrogen ions are present in high amounts, they bind with carbonate ions, which means that less carbonate is available to oyster larvae.

This can cause problems for oyster larvae that rely on calcium carbonate to build their shells. Because of this, oyster larvae appear to struggle to survive in acidified seawater. Lack of appropriate food is one of the most common reasons for oyster larvae's struggle to survive in acidified seawater.

The eccentricity of this orbit is approximately
A) 0.3
B) 0.8
C) 1.3
D) 0.5

Answers

The diagram below represents the construction of a model of an elliptical orbit of a planet traveling around a star. The focal point and the center of the star represent the foci of the orbit. The eccentricity of the elliptical orbit of a planet orbiting around a star is approximately (D) 0.5.

An elliptical orbit is an orbit where an object revolves around another object in an elliptical or oval shape and moves in an elliptical path. There are two foci in an elliptical orbit, with the star's center being the other focus. The foci of an ellipse are the points where the distance from the center of the ellipse to each focus point added up is constant, and is equal to the major axis of the ellipse.

The eccentricity of an elliptical orbit is a measure of how elongated the ellipse is. The distance between the foci is divided by the length of the major axis to calculate the eccentricity. An eccentricity of 0 indicates that the orbit is circular, whereas an eccentricity of 1 indicates that the orbit is a straight line.

The formula for eccentricity is e = c/a where c is the distance between the center and each focus, and a is the length of the major axis. Based on the given diagram, we can estimate the length of c and a. The major axis is the longest line in the ellipse, which passes through the center of the ellipse.

Therefore, we can measure the length of a by measuring the length of the major axis. Based on the diagram, the length of the major axis is approximately 8.6 centimeters. To calculate c, we need to measure the distance between the center and each focus.

Based on the diagram, the distance between the center and each focus is approximately 3.5 centimeters. Thus, c is approximately 7 centimeters (3.5 x 2). e = c/a = 7/8.6 ≈ 0.81 The eccentricity of the elliptical orbit is approximately 0.8, according to the calculation. The correct answer is D.
