Summarize what the differences in cytochrome C sequencing tells us about our evolutionary ancestry. How many amino acid differences between a rat and a fruit fly? Human and a yeast cell?
Answer:
Cytochrome C is a protein found in the mitochondria of all eukaryotic cells that plays a vital role in the process of cellular respiration. By comparing the amino acid sequence of cytochrome C between different species, scientists can infer information about their evolutionary relationships.
The number of amino acid differences between cytochrome C in different species indicates the amount of time that has passed since those species diverged from a common ancestor. The more amino acid differences there are between two species, the longer ago they diverged from a common ancestor.
For example, the cytochrome C sequences of a rat and a fruit fly differ by around 50 amino acids, indicating that they diverged from a common ancestor around 800 million years ago. On the other hand, the cytochrome C sequences of a human and a yeast cell differ by around 150 amino acids, indicating that they diverged from a common ancestor around 1.5 billion years ago.
Overall, cytochrome C sequencing can provide important information about the evolutionary history of different species and can help us understand how they are related to each other.

In some places, rain runs off quickly before it can flow underground.
FOR BRAINLIEST ALSO I THINK THS ONE CLD BE MORE THAN 1 ANSWER
Answer:
The following are some reasons why groundwater resources are unevenly distributed on Earth:
* The geology of some locations lets water pass through easily, reaching as far as Earth's magma. This is because the Earth's crust comprises different types of rocks, some more porous than others. Porous rocks have small spaces between the rock grains, allowing water to flow through them. The more porous the rock, the more water it can hold.
* Some climates get rain but not snow. Snow is needed for groundwater to collect. This is because the snowpack acts as a natural reservoir for water. When the snow melts, the water slowly seeps into the ground, where it can be stored as groundwater. In climates with little or no snow, groundwater resources are often limited.
* The geology of some locations is more favorable for trapping water underground. This is because some rocks are better at trapping water than others. For example, limestone is a rock that is very good at trapping water. When water flows through limestone, it can become trapped in small cracks and pores in the rock. Drilling wells can then access this water.
* In some places, rain runs off quickly before it can flow underground. This is because the land in these areas is not very porous. So when in these areas tends to run off the surface and into streams and rivers. This means less water is available to seep into the ground and become groundwater.
In addition to these factors, human activities can also affect the distribution of groundwater. For example, when building cities and roads, we often cover the ground with impermeable materials, such as concrete and asphalt. This prevents water from seeping into the ground, which can reduce the amount of groundwater available. We can also affect the distribution of groundwater by pumping water out of the ground for irrigation or other purposes. This can lower the water table, which is the level at which groundwater is found. When the water table is lowered, accessing groundwater can be more challenging.

Transcription and translation are two processes involved in protein synthesis. Amino acid sequence: Met-Trp-Asn-Arg-Cys-Stop
What are transcription and translation?
Transcription and translation are two processes involved in protein synthesis.
Transcription occurs first in the nucleus. During this event, mRNA is synthesized by copying a segment of the DNA molecule. The template DNA strand is used to pair its nucleotides and grow the new mRNA strand.Translation occurs in the cytoplasm. During this event, the protein is grown by reading the mRNA codon sequence. tRNA, associated with rRNA, recognizes the codons and adds the correct amino acid to the new growing polypeptide.DNA ⇒ TAC ACC TTG GCG ACG ACT

Water evaporates and condenses as steam in the atmosphere and droplets of water on the surface of the lid. The drops then fall to the handle, which is the lowest position, where they drip directly into the glass. This will most likely take twenty minutes or longer. Oceanic salt water is transformed into heat and evaporates into the atmosphere as a significant component of the water cycle. The salt doesn't evaporate with the water; it stays in the ocean. In the form of snow and rain, the water condenses into clouds & returns to the ground. Freshwater is returned to the ground through precipitation.

Jack conducted an experiment with two 15-gallon tanks labeled "A" and "B". He put 10 small goldfish in both tanks and measured the pH, which was initially 6.9. The next morning (Day I), he measured the pH again and found that both tanks had a pH of 6.7.
From Day 1 onwards, Jack added 2 small goldfish to "Tank B" every morning, while keeping "Tank A" the same day to day. This continued for 12 days, at the end of which "Tank B" contained 32 fish but died off. Based on Jack's results, it can be inferred that the addition of more goldfish to "Tank B" resulted in a decrease in pH levels, ultimately leading to the death of the fish. However, more information is needed to fully understand the cause of death (e.g. lack of oxygen, overcrowding, etc.).
To graph the data on the attached table, plot the number of fish in "Tank B" on the y-axis and the days (1-12) on the x-axis. The resulting graph should show a steady increase in the number of fish in "Tank B" until Day 12, at which point there is a sudden drop to zero.

The heart is a vital organ responsible for pumping blood throughout the body. It has four chambers, four valves, and is connected to a network of blood vessels consisting of arteries, veins, and capillaries.
The four chambers of the heart are the right atrium, right ventricle, left atrium, and left ventricle. The right atrium receives deoxygenated blood from the body through the superior and inferior vena cava, while the left atrium receives oxygenated blood from the lungs through the pulmonary veins. The right ventricle pumps deoxygenated blood to the lungs through the pulmonary artery, while the left ventricle pumps oxygenated blood to the rest of the body through the aorta.
The four valves in the heart are the tricuspid valve, pulmonary valve, mitral valve, and aortic valve. The tricuspid valve separates the right atrium and ventricle, while the pulmonary valve separates the right ventricle and the pulmonary artery. The mitral valve separates the left atrium and ventricle, and the aortic valve separates the left ventricle and the aorta.
Capillaries are the smallest blood vessels in the body, connecting arterioles to venules. They allow for the exchange of gases, nutrients, and waste products between the blood and the tissues. Arteries are blood vessels that carry oxygenated blood away from the heart, while veins carry deoxygenated blood back to the heart. The pulmonary artery and vein are exceptions to this, carrying deoxygenated and oxygenated blood respectively.

Can you think of some strong visual images that you have encoded without deliberately studying them? Why are these images different from the images that we forget so readily, like a penny?
Strong visual images that are encoded without deliberate studying are often associated with emotional significance or novelty.
For example, a person might remember the image of a beautiful sunset they saw on a romantic vacation or the sight of a loved one's face when they first met them.
These types of images are different from the images that we forget easily, like a penny, because they are connected to an emotional experience or a unique event, making them more salient and meaningful to our memory. When we encounter something that is emotionally significant or novel, our brains release neurotransmitters such as dopamine, which helps to consolidate the memory, making it easier to recall later on.
On the other hand, a penny is a familiar and mundane object that we encounter frequently, making it less likely to be encoded as a memorable visual image unless it is associated with a particularly unique or emotional event.

Responses
Hunters gathered less meat than the community needed.
Answer- Hunters depleted game resources in many areas.
People did not enjoy eating game meat.
People decided to only use animals only for non-food purposes.
The best explanation for why early cultures began raising cattle instead of hunting for meals is that hunters exhausted game supplies in many locations, making it more challenging to locate enough meat to feed the group. The right option is (2) Hunters depleted game resources in many areas.
Due to hunters' depletion of game supplies in many locations, early cultures began raising cattle rather than hunting for meat since it was difficult to acquire enough food to sustain expanding populations. Societies could have a consistent supply of meat and other goods like milk, wool, and leather by maintaining cattle. Animals could be grown and raised expressly for human consumption thanks to the domestication of animals, which also gave humans more control over the food supply. Agriculture was also made possible by the domestication of animals since they could be employed to plough fields and fertilize crops.
