When a fan is moving is convection, conduction, or raditation, and WHY?
Answer:
Moving of fan is convection.
The faster moving air from the fan displaces the warmer air that is in direct contact with our skin. This enhances the rate of convective heat transfer, which means we feel cooler.

What are biological macromolecules?Biological macromolecules are large molecules constituted of organic molecules. These are necessary for the survival of an organism. The four major classes of macromolecules in the study are Carbohydrates, Lipids, Proteins and Nucleic acids.
They are all built from carbon-based or organic molecules. These molecules form important components of a living cell and constitute most of its dry weight. These macromolecules are mostly obtained from the food we eat which is broken down into nutrients which are these organic molecules.
They are also called biomolecules. Carbohydrates are energy sources made of sugars. They are broken down into glucose which is required for cellular respiration to produce energy.
Proteins perform various functions including structural, regulatory, protective etc. Lipids are non-polar compounds that store energy for the long term in the form of fats in our bodies. Nucleic acids are hereditary biomolecules that pass on traits from one generation to another.
Therefore, the correct options are A, B, E and F.

1. Compare the density of stomata between the two varieties of olive plant A and B
2. Under identical environmental conditions the rate of water uptake in plant A is higher than plant B
Plant A has more stomata than plant B and therefore plant A can take more water, thereby under identical environmental conditions, the rate of water uptake in plant A is higher than in plant B (questions 1 and 2).
What are plant stomata?Plant stomata are structures located on the leaves which serve to absorb water and they also serve to the gas exchange processes during photosynthesis, which is fundamental because one output of this process is oxygen while the input is carbon dioxide.
The amount of plant stomata per unit of area is fundamental to determining the water intake rate that a plant has in certain environmental conditions.
Therefore, with this data, we can see that plant stomata are required to take water and also for gas exchange during photosynthesis, thereby a plant with more stomata will be able to obtain more water.

Nitrogen fixing bacteria living in the roots of legumes to absorb sugars from them is an example of:
A. Commensalism
B. Predation
C. Parasitism
D. Mutualism
Nitrogen-fixing bacteria living in the roots of legumes to absorb sugars from them is an example of mutualism. The correct option is D.
What is mutualism?Mutualism is an interaction between two organisms, in which both organism live together and help each other. In an ecosystem, different organisms live together as they affect the life of each other.
Nitrogen-fixing bacteria are the bacteria that are present in the roots of legume plants, like cereal plants. They convert the nitrogen of the environment into nitrate in the soils.
So, living in the roots of the legume plants, they get nutrition from the roots, and they give atmospheric nitrogen to the soil, which increases the nutrition of the soil and the plants.
Thus, the correct option is D. Mutualism.

Which of the following is NOT a response that the body would have to a stimuli?
A. physical response
B. chemical response
C. creating a feeling
D. evolving the body
Answer:
Explanation:D
The CNS, which is made up of the brain and spinal column, coordinates how the body reacts to stimuli.Motor neurones are used by the CNS to communicate with an effector.A hormone or a muscle in the body that causes a response is known as an effector.
How does your body respond to stimuli?
The creating feeling is not involve stimuli .Anything that makes you react, like the smell of food making your mouth moisten, is a stimulus.Body movements such as muscle contractions, gland secretions, or brain operations are responses. The stimulus is a change in the environment, and the response is how the organism responds to it.In single-celled organisms, the reaction is a result of a cell characteristic...An organism's senses, which are delicate components of his body, respond to stimuli. The sensory input from the outside world consists of touch, pain, vision, smell, taste, sound, and balance (equilibrium).External changes trigger the activation of these sensory impulses.Touch and pain: The stimulus that can have a significant impact on the body is pain.The definition of a response is a response to an activity.The way a person responds to an ink stain on a card is an illustration of response.An answer to a question is what is meant by a response.What follows a question in a question-and-answer session is an illustration of a response. Animals react to a stimuli in order to maintain their current circumstances.Examples of this include leaving a place that is too chilly and moving somewhere warmer.if hungry, moving in the direction of food. The body's automatic responses to a stimulus are known as physiological responses.The natural and instinctual physiological reactions we encounter every day are familiar to most of us, but we frequently ignore them. The various tastes of the various foods you eat are an example of chemical stimulation.When chemical messengers (hormones) interact with cells, biological stimuli are observed. To preserve homeostasis, your body also needs to keep secure and defend itself.In order to preserve homeostasis, the body reacts to stimuli.The body quickly resumes its normal state as a result of these intricate responses.We would get frequent fevers and other illnesses if they didn't.To learn more about stimuli refer

Describe the effect of increased carbon dioxide concentration on blood pH
Answer:
As it combines with water, it forms carbonic acid, making the blood acidic. So CO2 in the bloodstream lowers the blood pH. When CO2 levels become excessive, a condition known as acidosis occurs. This is defined as the pH of the blood becoming less than 7.35
The increase in the carbon dioxide concentration on blood pH leads to the condition known as Acidosis.
What is the normal blood pH?The level of normal blood pH in humans significantly ranges from 7.35 to 7.45 on a pH scale. It is considered neutral but experimentally it is slightly basic in nature.
As the concentration of carbon dioxide in the blood increases, the carbon dioxide in the presence of water forms carbonic acid which lowers the blood pH from 7.35.
This reduction in blood pH is known as acidosis. This is caused by the overproduction of acid within the body due to excessive concentration of carbon dioxide in the blood's pH. Acidosis leads to feeling fatigued, lethargic, muscle aches, etc.
Therefore, the concentration of carbon dioxide on blood pH negatively harms the health of an individual.

Answer:
Jay's speed-7.333 yd/s
Zeke's speed- 7.0 yd/s
Zeke's time-31.43 seconds
Step-by-step explanation:
-Speed is defined mathematically as distance over time.
-Given the distance as 220 yds and Jay's time as 30sec, her speed is:
#Given that Jay wins the race by 10yds, it means that Zeke was at 210 yds when Jay finished:
-Find Jay's time at d=210 yds:
#Zeke's speed for the race can now be calculated as:
#Time it takes for Zeke to finish:
Hence, it takes Zeke 31.43 seconds to complete the dash.

Inserting arginine places a positively charged amino acid in a portion that is non-polar, creating the possibility of a hydrogen bond in this area.
Explanation:
Inserting arginine places a positively charged amino acid in a portion that is non-polar, creating the possibility of a hydrogen bond in this area.
What are amino acids?The amino acids are the basic building blocks of the protein nutrient. They are made up of amino group (―NH2), an acidic carboxyl group (―COOH), and an organic R group.
An asymmetric center is the carbon atom that is bonded by four different molecules.Among all the amino acids, the ones that have more that one asymmetric center include the isoleucine and threonine.
Of all the types of amino acids listed above, isoleucine and threonine are the two amino acids that have more than one asymmetric center.The sequence to date is: leucine-methionine-tyrosine-alanine-glutamine-lysine-glutamate. You insert arginine between the leucine and methionine.
