Answer:
Measure only daytime.
Explanation:
It is useless to measure the oxygen production every hour for 24 hours because oxygen is produced during day time due to the presence of photosynthesis process. Oxygen is produced in large amount during photosynthesis, some oxygen is used in respiration while the remaining diffuse out from plant body through stomata. After vanishing sunlight, the photosynthesis process stop and no production of oxygen occur. So only measure oxygen production at daytime as compared to every hour for 24 hours.
Why is it important for cells of multicellular organisms to undergo mitosis? A) mitosis allows for reproduction B)mitosis increases variation within an organism. C) mitosis produces cells that are different from the original dividing cell. D)mitosis produces cells that are identical to the original diving cell
The answer is A mitosis allows for reproduction. This is because during mitosis two identical daughter cells are created which can contribute to an embryo.
Hope this helps ! <3
It is important for cells of multicellular organisms to undergo mitosis because mitosis produces cells that are identical to the original dividing cell. Thus, the right option would be D.
Mitosis involves the division of vegetative cells and it results in daughter cells with the same morphology and genome as the parent cell.
The division of vegetative cells in multicellular organisms will ensure that damaged or dead cells are replaced with cells of similar morphology and genome.
Apart from replacing dead or damaged cells, mitosis also allows multicellular to grow in size by allowing similar cells to spring from existing cells.

c) Assume that the concentration of the solute molecules varies over time on both sides of the membrane and that the solute molecules continue to pass through the membrane even when the concentration gradient is the reverse of the gradient shown. Describe the environment in and around the cell, as shown in the diagram, and the mechanism of transport of the solute molecules. (3 points)
Answer:
Does the movement of molecules stop when the concentration of a solute is equal on both sides of a membrane?
The concentration of solute molecules on both sides of the membrane will vary over time, and the solute molecules will continue to pass through the membrane even when the concentration gradient is reversed.
The environment in and around the cell is constantly. The diagram shows a cell with a higher concentration of solute molecules on the inside than on the outside. This means that there is a concentration gradient, and the solute molecules will tend to move from the inside of the cell to the outside. This process is called diffusion.
The solute molecules can also move through the membrane by other mechanisms, such as facilitated diffusion and active transport. Facilitated diffusion is a process that uses proteins in the membrane to help the solute molecules move across the membrane. Active transport is a process that requires energy to move the solute molecules across the membrane.
The concentration of solute molecules on both sides of the membrane will continue to change over time. As the solute molecules move from the inside of the cell to the outside, the concentration of solute molecules on the inside of the cell will decrease. This will create a new concentration gradient, and the solute molecules will continue to move from the inside of the cell to the outside.

Which is the best example of water regulating an organism’s body temperature? a jogger sweating after a run a fish passing water over its gills a deer taking a drink from a stream a leaf using water for photosynthesis
Answer: A. Jogger sweating after a run.
Explanation: I took the quiz. ;)
The best example of water regulating an organism’s body temperature is a fish passing water over its gills, which is the second option, as the fish gill maintains the body temperature and maintains the oxygen and carbon dioxide concentrations too.
What is the significance of the water-regulating system in an animal body?The water-regulating system in an animal body maintains homeostasis in the body, such as electrolytes homeostasis, such as ions such as sodium and potassium in body fluids, and the lungs ,skin, play a role in regulating water balance through respiration and sweating to maintain temperature of the body.
Hence, the best example of water regulating an organism’s body temperature is a fish passing water over its gills, which is the second option, as the fish gill maintains the body temperature and maintains the oxygen and carbon dioxide concentrations too.

describe the active site of an enzyme. why is it important?
Answer:
An active site contains a binding site that binds the substrate and orients it for
catalysis. The orientation of the substrate and the close proximity between it and
the active site is so important that in some cases the enzyme can still function
properly even though all other parts are mutated and lose function.

Building Polymers
Monomers are the building blocks of larger molecules called polymers. A polymer consists of repeating monomers bonded to each other with covalent bonds.
Use the drawpad to connect each monomer to its polymer.
Answer: I'm doing the same homework. I'm pretty sure that the 6 hexagons are the startch glucose. Try page 2
Explanation:
Each monomer is correctly connected to its polymer in the attached image in which amino acid is attached with protein, the nucleotide is connected to DNA, the fatty acid is attached to fat or lipid, and glucose or sugar is attached to carbohydrates.
Monomers are the basic unit or building blocks of larger molecules known as polymers. Polymers are made up of two or more monomers or long chains of monomers attached together.
The macromolecules are polymers and made up of their particular monomers:
Proteins made up of amino acids: In the protein structure there are many amino acids are joined together with help of peptide bonds and due to this, it is also called a polypeptide chain.Nucleic acid (DNA) is made up of nucleotides- nucleotide monomers bind together and form chains of the nucleotides.Fat made up of fatty acids: Fats or lipids are polymers made up of long chains of fatty acids,carbohydrates made up of glucose monomers: glucose or other monosaccharides bind together to form polysaccharides or carbohydrates.Thus, the correct answer is attached as the image.

A. The power he used to move the boxes can be found by determining the rate at which work was done on the boxes.
B. The power Chad used to move the boxes is the force he used times the distance he moved them.
C. The power of the light Chad turned on is the amount of energy changed from electricity to light.
D. The power of the light Chad turned on is the amount of energy transferred per time.
2)Raul dug a hole in his yard to repair a water pipe. It took him 2 seconds to apply a force of 50 Newtons to push the shovel 0.25 m into the ground. How much power was used?
A. 0.01 watts
B. 6.25 J/s
C. 25.00 N•m•s
D. 100.00 watts
Answer:
1.) A and D
2.) B
Explanation:
The power he used to move the boxes can be found by determining the rate at which work was done on the boxes. The power of light Chad turned on is the amount of energy transferred per time. So the correct options are A and D. In 2nd, the power used was 6.25 J/s. So the correct option is B.
What is power?
The watt, denoted by the letter W, is the common unit used to measure power. James Watt, a Scottish businessman and inventor, is honoured with the unit's name. The watt is certainly a term you frequently encounter in daily life. Electrical devices like light bulbs and stereos commonly advertise their power output in watts. One watt is equivalent to one joule of work performed each second by definition.
Horsepower is another power unit that is still extensively used. This was first used to describe the ability of a regular horse to spin a capstan in the 17th century and is often represented by the sign hp. Since then, a metric horsepower has been defined as the force needed to raise a 75 kg mass a metre in one second, where 75 kg is the mass's weight in kilogrammes.
Therefore, for 1) the correct option is A and D and for 2) the correct option is B.
