ow do cells use food to make energy and maintain homeostasis
Answer:
Cells obtain energy through the process of cellular respiration. It is a metabolic process of conversion of the biochemical energy from the nutrients into adenosine triphosphate (ATP). ... They exchange substances with the new cells and also eliminate the wastes thereby maintaining homeostasis.
Explanation:
There are several ion transport mechanisms within the cell membrane that function to maintain proper levels of solutes inside and outside the cell. ... This system uses the energy stored in ATP to pump potassium into the cell and sodium out of the cell.
7. How does your respiratory and circulatory systems attempt to maintain homeostasis
during exercise?
a. Your body produces more red blood cells to help provide energy to cells.
b. Your lungs produce more oxygen which is then delivered to the cells through the
blood.
c. You experience an increase in blood flow which provides nutrients to cells to
increase energy and remove wastes.
d. You experience an increase in breathing rate to obtain more oxygen which is
delivered to cells through the bloodstream.

what are the most common c0vId vaccine myths and how did they start? Explain your answer.
Answer:
The most common myths are:
- C0vid2019 vaccines cause autism
- C0vid2019 vaccines may modify your DNA
- C0vid2019 vaccines are unsafe
Explanation:
The most common myths associated with C0vid2019 vaccines are:
1- C0vid2019 vaccines may cause autism: In 1998, Andrew Wakefield and colleagues published a controversial study in the Lancet where they suggested that the measles, mumps, and rubella (MMR) vaccine may cause autism in some children. However, it has been showed that this study was based on erroneous statements and therefore this publication was retracted.
2- C0vid2019 vaccine may modify your DNA: it has been suggested that vaccines based on viral vectors (e.g. adenoviruses) and mRNA vaccines may modify the DNA of cells. This statement is false because these technologies cannot alter the DNA sequence. These vaccines are based on the production of an mRNA sequence that is translated into a viral protein (spike protein) which triggers an immune response
- C0vid2019 vaccines are unsafe: some people believe that C0vid2019 vaccines are unsafe because they were developed quickly. However, this statement is false because all vaccines (including C0vid2019 vaccines) need to follow rigorous safety standards to be approved by governmental agencies (i.e., they approved all clinical trials).
Explain how the cell division of cancer cells like these are misregulated. Identify genetic and other changes that might have caused these cells to escape normal cell cycle regulation
Answer:
Due to non-functioning of protein.
Explanation:
The cell division of cancer cells like these are misregulated because they can't be control by the proteins that is responsible for the control cell division. The cancer cells can multiply without any growth control factors, or growth-stimulating protein signals that control its growth. There are some proteins that is responsible for control of cell division but due to mutation that protein of substance stop working and the cancer cell grows uncontrollable.
Identify ALL of the functions of proteins. Structure and is found in tendons, bones, and ligaments. Communication and works as chemical messengers such as hormones. Defense as in antibodies. Transportation and are embedded in the cell membrane to allow substances to move across the cell membrane. Enzymes that lower the activation energy of a reaction. Contraction to allow muscle and cell contraction/movement. Eicosanoid such as in regulation of blood pressure or inflammation. Steroids such as cholesterol. Glycogen for energy storage in muscles.
Answer:
Structure and is found in tendons, bones, and ligaments.
Communication and works as chemical messengers such as hormones.
Defense as in antibodies.
Transportation and are embedded in the cell membrane to allow substances to move across the cell membrane.
Enzymes that lower the activation energy of a reaction.
Contraction to allow muscle and cell contraction/movement.
Explanation:
Proteins serve many functions in living organisms.
Structure: The most abundant protein in mammals is collagen and is found throughout the body. In a major component of connective tissue such as skin, ligaments, and tendons providing strength and elasticity to these tissues. It is found also mineralized in bones and teeth.
Proteins function as hormones which are chemical messengers that mediate many cellular responses in the body. For example, the hormone insulin is a protein.
Proteins functions in the body's immune system as antibodies which recognize and initiate immune responses against diseases. The immunoglobulin such as immunoglobulin A and G are proteins.
Proteins serves as transporters to move substances across the cell memebrane. Some are found as peripheral or integral membrane proteins. Examples of transport proteins are the glucose transporters, Glut-1, Glut-2 and Glut-4 transporters.
Enzymes are proteins which catalyse the chemical reactions tanking place in an organisms. Various enzymes in the body include the hydrolases, the ligands, the leases, etc.
Contraction of the actin filaments of the muscle which are proteins, allow muscle and cell contraction bringing about movement.
A Note on the other options.
Eicosanoids are lipid molecules which serve various functions such as in regulation of blood pressure or inflammation.
Steroids such as cholesterol are lipid-derived molecules.
Glycogen for energy storage in muscles is a storage form of glucose, a carbohydrate.

what is crop rotation
Answer:
MARK ME BRAINLIST
Explanation:
the practice of growing different crops in succession on the same land chiefly to preserve the productive capacity of the soil.
Answer:
Crop rotation was used during the agricultural revolution. It allowed the soil to be healthier and prevented the nutrients from being stripped from the soil. Crop rotation is when your land in separated into different fields for different plants. Usually you would have two or three. One field is left fallow (land that is taken care of, but does not have any crops), and the other one/s are for whatever you choose to plant. Each season you rotate your crops so each field has a turn to be fallow.
Explanation:
Example: you separate your land into three fields. Field 1 has potatoes, field 2 has wheat, and field 3 is fallow. Next season Field 1 is fallow, Field 2 has potatoes, and Field 3 has wheat.

Gametes produced by the parents are shown along the __________________ and _______________ sides of the Punnett square.
Answer:
Vertical and horizontal
Explanation:
A punnet square is a tabular chart used in genetics to display the genotypic composition of the offsprings of two parents. To construct a punnet square, the alleles of the gametes produced by the parents is required.
The gametes produced by each parent via meiosis are placed along the vertical and horizontal sides of the punnet square. For example, if a cross occurs between two parents with the following genotype: AaBb and AAbb. The parents will produce the following gametes:
AaBb - AB, Ab, aB, ab
AAbb - Ab, Ab, Ab, Ab
These gametes produces by each parent will be placed along the sides (vertical and horizontal) of a punnet square to determine the genotype of the offsprings that will be produced.
A researcher stimulates, with a small electrical charge, a portion of a cat's limbic system. The cat suddenly jumps and acts as if it is fighting. What portion of the limbic system was stimulated
Answer: amygdala
Explanation:
The limbic system, refers to the set of brain structures that's located on the sides of the thalamus. The function of the limbic system include olfaction, behavior, emotion, and long-term memory.
Since the cat suddenly jumps and acts as if it is fighting, the portion of the limbic system that was stimulated is the amygdala.
