To back up the scientist, when a person is more fit, their breathing will return to a normal rate faster than average, as B's rate returned faster than everyone else's, they are more fit.
Another reason the scientist could be right, is when a person is very athletic and fit, their resting heart beat is lower than an average person's heart rate. As person B has the lowest at 10, this would make them more fit.
2.
If the scientist counted wrong at all while measuring breath rates, the results could be wrong.
If each person did a different form of exercise, the results could also be wrong as different forms of exercise for each person would make the expirement inconclusive. (some exercises take more from the body than others).

why are vitamins important to enzymes and what this relationship is called?
Answers
The activity of some enzymes requires vitamins. This is because vitamin derivatives contribute to the biochemical mechanisms of these enzymes. These vitamin derivatives belong to a class of molecules known as cofactors, which are organic molecules (called coenzymes) or metallic ions, that assist in the catalytic activity of an enzyme.
What is the independent variable of great white sharks travelling distance?

hydrophilic
phospholipid
Answers
Answer:
hydrophilic
Explanation:
Large polar or ionic molecules, which are hydrophilic, cannot easily cross the phospholipid bilayer. Charged atoms or molecules of any size cannot cross the cell membrane via simple diffusion as the charges are repelled by the hydrophobic tails in the interior of the phospholipid bilayer.

The difference between pinocytosis and receptor-mediated endocytosis is that _____. Question 14 options: pinocytosis can concentrate substances from the extracellular fluid, but receptor-mediated endocytosis cannot. pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis offers more selectivity. pinocytosis brings only water molecules into the cell, but receptor-mediated endocytosis brings in other molecules as well. pinocytosis increases the surface area of the plasma membrane, whereas receptor-mediated endocytosis decreases the plasma membrane surface area.
Answers
Answer:
The difference between pinocytosis and receptor-mediated endocytosis is that pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis offers more selectivity.
Explanation:
Pinocytosis and receptor-mediated endocytosis are two types of endocytosis.
The first one consists of plasmatic membrane invaginations that capture extracellular fluid with different nutrients and sends it to the inside of the cell in vesicles. The second one, receptor-mediated endocytosis, consists of receptors on the outside of the plasmatic membrane and clathrin proteins on the interior side of the membrane. When the receptors are in contact with its specific molecule, a vesicle surrounded by clathrin proteins, is formed transporting specific molecules to the cell's interior.

How does bursting of animal cells take place
Answers
Answer:
Swelling and bursting of cells is also known as lysing. This happens when the concentration of solutes inside the cell is greater than the concentration of solutes outside the cell. It has to do with diffusion and osmosis. A high solute concentration relates to a lower water concentration. Since molecules like to diffuse from areas of high concentration to areas of low concentration, water will rush into the cell where the water concentration is lower causing it to swell and lyse.

Which of these energy transformations is taking place in the chimpmunk when its cells use the plants sugars to carry out cell processes?
Answers
Answer:
This question lacks options, the options are:
A. chemical energy -> kinetic energy
B. kinetic energy -> solar energy
C. solar energy -> chemical energy
D. kinetic energy -> nuclear energy
The correct answer is A.
Explanation:
All living organisms need energy to carry out certain processes in their body. This energy is obtained in form of ATP (chemical energy) when their food molecules is broken down via a process called CELLULAR RESPIRATION.
This chemical energy (ATP) is needed to perform cellular processes in the body. According to this question, a chipmunk (animal) will utilize the energy it derives (ATP) from breaking down plant sugars to carry out its cell processes. This means that it will transform CHEMICAL ENERGY → KINETIC ENERGY.
Note that, kinetic energy is the energy due to motion in the Chipmunk.
