What kind of molecule forms from polysaccharide chains that are very
strong?
O A. Protein
B. Cellulose
C. Monosaccharide
D. Lipid
SUBMIT
PREVIOUS
Answer:
B. Cellulose
Explanation:
Polysaccharide are substances that contains many units of monomers called MONOSACCHARIDE. They are carbohydrate molecules consisting of very long chains of monosaccharides like glucose, galactose etc.
An example of molecule that forms from strong chains of polysaccharides is CELLULOSE, which consists of long chains of glucose units linked together by B-1,4-glycosidic bonds. Cellulose is the most abundant polysaccharide on Earth found in plant cell walls.

P680 is said to be the strongest biological oxidizing agent. Given its function, why is this necessary
Answer:
The correct answer is - it obtains electrons from the oxygen atom in a water molecule, so it must have a stronger attraction for electrons than oxygen has
Explanation:
P680 known as which contains a reaction center in photosystem two, it is a very strong oxidizing agent that catalyzes the transfer of electrons from H2O to a bound quinone, with the production of O2.
To have a stronger attraction for electrons than oxygen has, P680 gets electrons from the O2 atom in a water molecule.
Why do the plant cells in these two images have different structures?
A. Because every plant cell has a different structure
B. Because they are in different stages of development
C. Because they have different jobs, or functions
D. Because the DNA in their nuclei are very different
Answer:
C
Cells have different shapes because they do different things. ... The shapes of cells have evolved to help them carry out their specific function in the body, so looking at a cell's shape can give clues about what it does. Neurons are cells in the brain and nervous system.
The plant cell in the images have different structures because they have different jobs, or functions
Why are all plant cells have different structures?All plants are very different because of their environments.
Plant cells are different in shapes because they are in different places in the plant and do different jobs. Some cell stores food,some perform photosynthesis etc.- Animal cells also have many shapes like nerve cells, germ cells etc.According to options:-

A certain regulatory gene is involved in controlling the expression of other genes. In studying this regulatory gene, a scientist discovers that it encodes for an enzyme that causes histone deacetylase (the removal of acetyl groups from histone tails). Based on this information, how would you predict that this enzyme regulates gene expression
Answer:
by an epigenetic mechanism
Explanation:
Epigenetics can be defined as the study of mitotically heritable gene expression changes that do not involve alterations in the DNA sequence. There are three different epigenetic modifications that work together either to activate or repress gene expression: DNA methylation, histone modifications (e.g., methylation, acetylation, phosphorylation, etc) and regulatory non-coding RNAs (e.g., long non-coding RNAs, microRNAs, piwi-RNAs, etc). Deacetylases are enzymes that play roles in epigenetic gene regulation by removing acetyl groups from lysine (K) residues located at the N-terminal end of histones H3 and H4. Histone deacetylation modifies the structure of the chromatin, thereby activating or suppressing gene expression in a context-dependent manner.
How many chromosomes are found in the common strawberry found in the grocery stores?
Answer:
In total, they have 56 chromosomes
Explanation:
Unlike Humans which has two copies of 23 chromosomes (in total 46) common strawberries have 8 copies of 7 chromosomes hence why they have a total of 56 chromosomes.

Is there anyone who can help me pls in biology this is the end of the semester I need help pls
Answer:
what do you need?
Explanation:
9. Doctors tested a patient to find out what molecules were in her cells. Her cells contained normal
levels of oxygen molecules, low levels of amino acid molecules, and low levels of glucose molecules
Will this patient be able to exercise normally?
a
Yes, as long as her cells have enough oxygen, her body will be able to exercise,
b
No, her cells need glucose to react with oxygen to release enough energy to exercise.
С
No, her cells need amino acids to react with oxygen to release enough energy to exercise.
d
No, her cells need glucose to react with amino acids to release enough energy to exercise.
Answer:
b. No, her cells need glucose to react with oxygen to release enough energy to exercise.
Explanation:
Living organisms are able to perform any of their day-to-day activities due to the release of energy in their individual cells. The process by which this energy is obtained by their cell is called CELLULAR RESPIRATION. Cellular respiration is the process whereby glucose (from digested food) is broken down in the presence of oxygen to yield energy in form of ATP. The general equation is as follows:
C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 + 6H2O + ATP
According to this question, a doctor is said to test a patient for the content of molecules in her cells. Her cells were found to contain normal levels of oxygen molecules, low levels of amino acid molecules, and low levels of glucose molecules. This patient will NOT BE ABLE to exercise normally because her cells need glucose in optimal amount to react with oxygen to release enough energy to exercise.
The ability to grow differently colored fur based on the season provides Arctic foxes with a selective advantage. What do you think that is
Answer:
This is known as Phenotypic plasticity, the artic fox has the advantage of being able able to hunt rodents, birds and fish
Explanation:
Phenotypic plasticity can be explained as the changes in the behavior, morphology, physiology of an organism such as the artic fox in response to their unique habitat. It tells us how the artic fox is able to cope with the variations in it's environment.
Their natural hues helps them to blend into snow and ice since it is white. When there's a change in season, their fur or coat also changes as well to a brown or grey color that gives it cover when it is among rocks and plants.
These colorings gives them an advantage and help them to hunt rodents, birds and fishes.
This is known as phenotypic plasticity, but artificial foxes have the advantage of explaining rodents, birds, and fish fox reactive to their unique habitats.
It will tell you how artistic foxes can handle environmental fluctuations. Her natural shades help you mix himself with snow and ice like white. If there is a change in change in the season, it will change with a brown or gray color that covers it when the coat or coat is also under rock or plants. This dyeing benefits you, helps to hunt rodents, birds, and fish.
What are adaptations in arctic foxes?Arctic foxes have several adaptations to survival. The round and compact body minimizes the surface area exposed to cold air. Their noses, ears, and feet are short and warm.
Hence it concludes that phenotypic plasticity in arctic foxes causes different colored fur to grow.

Compare and contrast the cell membrane with the cell wall. *
Explanation:
For one, the cell wall is found only in plant cells, as it needs more protection. The cell wall is also found in the cells of plants, fungi, and bacteria. It can also be found rigid or smooth.
The cell membrane is found in both plant and animal cells. It controls what enters and leaves the cell. It surrounds the cytoplasm of the cell.
What are some examples of metabolic processes in cells? (Choose all that apply)
Answer:
Metabolism is a set of chemical reactions that they release energy for cellular processes.
Explanation:
Metabolic processes in cells are:
* Metabolism-the whole of all chemical processes, that is, the total turnover of matter and energy is called metabolism.
* Cellular respiration-a process in which organic matter is oxidized, whereby carbon dioxide, water, and energy in the form of ATP molecules are formed as end products of this oxidation.
