Answer:
Small Intestine
Explanation:
Most digestion and absorption of nutrients take place in the small intestine.
How do foods digest in humans?The digestion of food materials starts from the mouth, depending on the class of the food.
The digestion is aided by a variety of enzymes. From the mouth, digestion continues through the gastrointestinal tract vis a vis the esophagus, the stomach, large, and the small intestine.
However, most digestive activities happen in the small intestine as well as most absorption of nutrients into the bloodstream.

In three to five sentences, describe the advantages and disadvantages of these maps in modeling mitosis.
Answer:
Maps have the advantage of objectivity and presentation of all phases of mitosis, but their disadvantage is the suppression of information, which can confuse students. A scientific model (or map) must be able to present a scientific process or element as it actually occurs, or as close to it
Explanation:
Give an example of how water acting as a solvent is important for living organisms.
Answer:Water acts as a solvent of carbon dioxide excreted from tissues, in blood and helps in regulating pH (because it forms carbonic acid that lowers pH when it tends to get higher). Blood pH should be maintained at about 7.4. One major reason is that the structure of protein is dependent ton pH because pH determines its ionization hence also affecting the charges and interaction between side groups of amino acids. A change in pH may, therefore, denature proteins and negatively affect cellular functions.

Examine the flow chart above depicting the job of a gene known as p53. It plays an important role during the G2 checkpoint of cell cycle regulation. In 4-6 sentences, explain why p53 is often called "The Guardian of the Genome". Is p53 an oncogene (a gene that stimulates the growth of cancer cells) or a tumor suppressor gene (a gene that turns off the growth of cancer cells)? Explain your reasoning.
The p53 protein is known as the guardian of the genome because this protein prevents errors during DNA replication. It is a tumor suppressor gene.
Tumor suppressor genesTumor suppressor genes are genes that play fundamental cellular roles and prevent cell uncontrolled growth.
A tumor suppressor gene can repair errors that occurred during DNA replication, slow down the cycle of cell division, trigger programmed cell death, etc.
The p53 acts to control cell division and cell death, thereby avoiding the emergence of cancer cells.

What does mitochondria do
Answer:
Mitochondria are small structures that make energy in almost all of your cells. They do it by combining oxygen with fuel molecules (sugars and fats) that come from food. When mitochondria are faulty, cells don't have enough energy.Explanation:

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Which statement is an accurate comparison of aerobic and anaerobic respiration in humans?.
Answer:
glucose → lactic acid.
Explanation:
hope it helps
The statement that will best compare aerobic and anaerobic respiration is :
More ATP is generated during aerobic respiration than during anaerobic respiration.Aerobic respiration is the type of cellular respiration which is a fixed metabolic reaction that occurs in the presence of oxygen while anaerobic respiration ia a type of cellular respiration which occurs in the absence of oxygen. Both respirationary process yields the required energy ( ATP ) in an organism that facilitates the proper functioning of the organism.
Hence we can conclude that The statement that will best compare aerobic and anaerobic respiration is : More ATP is generated during aerobic respiration than during anaerobic respiration.

if a plant is not green (does not contain chlorophyll) can it do photosynthesis? why or why not?
Answer:
No, it cannot carry out photosynthesis because the plant will not be able to absorb light as it does not have chlorophyll.
Explaination:
Chlorophyll in plants is used for absorbing energy from light. And, in photosynthesis, light/sunlight is one of the main factors needed, so as the plant cannot absorb light, photosynthesis can't take place.
How do I describe chloroplast
Answer:
a plastid that contains chlorophyll and in which photosynthesis takes place.
or

Label the following with
N (neutron), P (proton),
E (electron)
___Negative charge
___ Atomic number ___determination
___ Atomic mass determination
___ Involved in bonding
___ Positive charge
___ when gained or lost creates ions
___ Neutral charge
___ Found in nucleus
Answer:
E, P, N and P, E, P, E, N, N and P
Explanation:
I am pretty sure the answers would go like this (in the order you have here):
1. Electron (they have a negative charge)
2. P (The atomic number is determined by the number of protons)
3. N and P (The atomic mass is determined by how many Neutrons and Protons there are in the atom)
4. Electron (they are usually involved in bonding)
5. Proton (they have positive charge)
6. Electron (ions are created when an atom has gained or lost electrons)
7. Neutron (they are neutral)
8. Both Neutrons and Protons (they stick together inside the nucleus)
I am not entirely sure why the atomic number determination has 2 blanks since it is only determined by protons, but I hope this helps. I havent studied this for a while but those are the best answers I can provide and have checked them with my books so I hope they are correct. Good Luck!

brainliest goes to best answer! Explain the flow of energy as it is transformed through photosynthesis AND aerobic cellular respiration.
Be sure to explain how energy is processed and changed as it passes through and between each process.
EX: Stored energy in gas is converted to heat when you light the stove. This heat is transferred to the food as heat energy while it cooks.
The correct order of flow of energy and its conversion is
Light energyChemical energyPotential and Kinetic energyDuring photosynthesis, plants converts light energy from the Sun into
chemical energy in the form of glucose. Cellular respiration involves the
conversion of chemical energy from glucose into potential and kinetic
energy by body cells
The chemical energy from glucose is converted into ATP which is another
form of chemical energy.The ATP formed helps cells perform various
activities and state of rest such as sleeping in the body through the
conversion of the chemical energy into kinetic and potential energy
respectively.
