During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
Does an animal cell have a cell wall?
Answer:Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall
Explanation:
Answer:
No
Explanation:
Animal cells have cell membranes, but not cell walls. Cell walls are much more structured and are only present in plant cells who also have a cell membrane.

The shape of each of the molecules is important because A) if the shape of any molecule in an organism changes, the DNA in that organism will also change B) the shape of a molecule determines the age of an organism C) the shape of a molecule determines how it functions in chemical reactions D) molecules having different shapes are always found in different organisms
Answer:
The correct answer would be - C) the shape of a molecule determines how it functions in chemical reactions
Explanation:
The molecular shape of the molecules is one of the important characters of the molecules. It is important due to the fact that molecular shape determines how a molecule will react and interact with other molecules.
The shape of the molecules determines boiling point, melting point as well as various chemical reaction by determining the bonds. For instance, H2O or water has a tetrahedral shape which affects its bonding and properties. If molecules were linear in shape there would be no life existed.
Thus, the correct answer would be - C)

A cookie recipe uses 3 cups of flour to make 15 cookies. How many cookies can you make with this recipe with 4 cups of flour. (assume you have enough of the other ingredients.)
Answer:
20 cookies
Explanation:
we are given that
three cups of flour is used to make 15 cookies
3 cups of flour is used to make=15 cookies
one cup of flour will be used used to make 15/3 cookies that will be 5
1 cup of flour is used to make =15/3=5
for 4 cups of flour we will multiply 4 on both sides
hence t will give
4 cup of flour is used to make =5*4=20 cookies
So,
According to recipe 4 cup of flour is used to make 20 cookies

ASAP The levels of water and salt in the blood are controlled by the ________, which is controlled by the ________.
Answer:
the hormone that regulates the salt and water levels is aldosterone found on the adrenal gland that sits above the kidney
Explanation:
Aldosterone, a hormone found in the adrenal gland above the kidney, regulates salt and water levels which are usually regulated by the renin-angiotensin system.
What is aldosterone?Adrenal glands secrete aldosterone, a steroid hormone. Its primary function is to regulate salt and water in the body, thereby influencing blood pressure.
It is actually regulated by a system namely the renin-angiotensin system.
Thus, aldosterone, a hormone found in the adrenal gland above the kidney, regulates salt and water levels which are usually regulated by the renin-angiotensin system.

Scientists insert a gene from a firefly into the genome of certain bacterial species. When these bacteria are placed into tobacco plants and exposed to certain conditions, the plants will glow. Tobacco plants without the bacteria do not glow. Which conclusion is best supported by this experiment?
A. The firefly and bacteria share a common genetic code.
B. The bacteria transferred light-producing proteins to the plant.
C. The firefly and tobacco plant have a recent common ancestor.
D. Tobacco plants lack the ability to translate the genetic code of firefly gene.
The answer is A.
A GENE is being inserted into the tobacco plant, which permits it to glow.
The conclusion that should be best supported by this experiment is option A.
Supported by the experiment?At the time when the bacteria should be placed into the tobacco plants so here tobacco should be without the bacteria and this can't be glow. Also, the gene should be added into the tobacco plant moreover, the firefly and bacteria shared the common genetic code
