Answer:
B) binding of a molecule to a binding site affects the binding properties of another site on the protein.
Explanation:
In an allosteric interaction between a protein and a ligand, the ligand binds to a site in the protein. As a result, there is a change in the properties of other active sites on the protein. These active-site changes may or may not allow the protein to bind to other molecules. There is a change in the protein that affects the affinity of the active site for other molecules. The affinity on the active site increases if the protein binds to an activator and decreases if the protein binds to an inhibitor molecule.
In a well-fed human eating a Western diet, the richest source of stored chemical energy in the body is ________. In a well-fed human eating a Western diet, the richest source of stored chemical energy in the body is ________. glucose in the blood fat in tissue calcium phosphate in bone glycogen in muscle cells protein in muscle cells
Answer:
fat in tissue
Explanation:
Biomolecules like carbohydrates, fats etc. are well known for their energy storing abilities. Glucose, as a carbohydrate, is the most used source of energy but is stored in excess as glycogen in the muscle and liver cells.
However, fats are far more efficient in storing energy than carbohydrates or proteins because they give more ATP per molecule. Fats are stored in tissues of the body called ADIPOSE tissues. Hence, the richest source of stored chemical energy in the body is FATS IN TISSUES.

If Darwin knew of Mendel's work, how might it have influenced his theory of evolution? Do you think this would have affected how well Darwin's work was accepted?
Answer:
See explanation
Explanation:
According to Darwin, the determinant of the ability of species to thrive in their environment is their ability to develop favourable characteristics which enable them to survive in their environment. This ability to develop favourable characteristics is called natural selection.
These favourable characteristics are passed on from parents to offsprings and are responsible for the perpetuation of organisms having these favourable characteristics in comparison to other members of the same species.
In relation to Mendel's theory, these favourable characteristics could be regarded as Mendel's factors (currently identified as genes). These factors are units of inheritance passed on from parents to offsprings.
If Darwin had an idea of Mendel's work when he propounded his evolution theory, he could have modified his idea of favourable characteristics to imply genes. This would have made his idea more empirical than speculative and led to a faster world wide acceptance of his ideas.
plants make glucose using energy from the sun and two molecules. which two molecules do they use ?
Nitrogen is the most common element in the air. Why do bacteria play a role in the nitrogen cycle?
Explanation:
Bacteria play a role in the nitrogen cycle because:The bacteria’s helps in breaking down the organic materials which has nitrogen in it, and helps in giving the nitrogen back to the cycle. Bacteria helps in breaking down of the leaves and then it diffuses the nitrogen to the soil. Prokaryotes also plays an important role in the nitrogen cycle. The nitrogen fixing bacteria present in the root zone of plants basically in the soil, helps in conversion of the nitrogen into ammonia. Then the nitrifying bacteria converts the ammonia to the nitrites or can say nitrates.

An amino acid analyzer is an instrument used to determine a. the sequence of amino acids in a polypeptide chain b. the presence of modified amino acids in a protein c. the identity of N-terminal and C-terminal amino acids in a protein d. the identities and relative amounts of amino acids in a protein
Answer:
d. the identities and relative amounts of amino acids in a protein
Explanation:
An amino acid analyzer is an automated machine that is used to determine the identities and quantities of amino acids in a given protein, peptide, and cellular samples. It makes use of the ion-exchange chromatography principle to determine the presence of amino acids. When the chromatogram is obtained, the relative amounts are then determined by the analyzer.
Since proteins are made of sequences of amino acids, the identities of proteins can also be obtained through this method. Ninhydrin, in the chromatographic column, reacts with the present amino acids under an ultra violet detector and is then observed at a wavelength of about 440 - 570nm.

In what ways is a eukaryotic cell similar to a city?
Answer: In many ways, the eukaryotic cell is kind of like a city. I will tell you what each of the organelles in a cell does. Your job will be to try to match each of the cell parts to the parts of a city and explain why they are similar. a) Golgi Apparatus: packages up proteins and labels them for distribution to other parts of the cell.
Each one, like the organs inside your body, fulfills a particular function that is required for the cell to stay alive. Consider the cells to be a miniature city. Because they all do similar jobs, the organelles could represent companies, places, or parts of the city.
What is a cell?Cells are the fundamental building blocks of all life. Gazillions of cells make up the human body.
They support the body's structure, absorb nutrients from food, convert those nutrients into energy, and perform specialized functions.
Each one, like the organs in your body, performs a specific function that is required for the cell to survive. Think of the cells as a miniature city.
Because cell city has jobs that a plant cell does not, it represents an animal cell. In cell city, we believe that a waste disposal plant performs the same function as lysosomes, an organelle found only in animal cells.
Thus, this way, a eukaryotic cell similar to a city.

14). Clonal selection and differentiation of B cells activated by antigen exposure leads to the production of ________. A) large quantities of the antigen initially recognized B) vast numbers of B cells with random antigen-recognition receptors C) long-lived erythrocytes that can later secrete antibodies for the antigen D) short-lived plasma cells that secrete antibodies for the antigen
Answer:
The correct answer is D) short-lived plasma cells that secrete antibodies for the antigen
Explanation:
Each B lymphocyte has an antigen receptor (BCR: B cell receptor), a surface immunoglobulin (IgM or IgD), that binds to specific domains of the antigen called antigenic determinants or epitopes. Only B lymphocytes with a high antibody affinity for the antigen, and which are capable of processing and presenting it, will be positively selected. In this contact between the two cells, an exchange of chemical signals takes place that leads to the activation, clonal proliferation and differentiation of B cells into two sister subclones: one of antibody-secreting plasma cells, and the other of memory primed B cells. Therefore, only these last positively selected B lymphocytes will survive, proliferate and differentiate into plasma cells, synthesizing and secreting antibodies of a single isotypic class, with a unique specificity and high affinity, improving the ability to adhere to the antigen and, thus , neutralize and destroy pathogens.

Many plant pathologists believe that plant resistance is based upon the interplay of different signaling molecules? Justified.
Answer:
Yes.
Explanation:
Many plant pathologists believe that plant resistance is based upon the interplay of different signaling molecules because plants have various signaling molecules that plays a great role in their growth and development. Ethylene, auxin, cytokinins, gibberellins, and abscisic acid are the growth regulators that controls the growth of plants in different conditions i.e. in resistance. These signals leads the plant to take measures in difficult situations experience by the plants so in this way the plant is resistance to the harsh environmental condition.

When observing a plant cell under a microscope, what parts do you think would be big enough to see?
Answer:
Explanation:
There are a few key structural differences between plant cells and animal cells.
Below are a few of the main ones:
Plant cells are generally larger than animal cells.
Only animal cells have lysosomes (however, recent, and controversial, research suggests that some plant cells may have lysosomes), and only plant cells have chloroplasts.
While plants cells have a rigid cell wall, animal cells have a thin and flexible plasma membrane.
Plants cells have a large central vacuole and animal cells have many small vacuoles
When observing a plant cell under a microscope, one can see large interlocking rectangular blocks. Around each cell, the cell wall is clearly visible. When stained, the cell wall is somewhat thick and visible. The cytoplasm is also lightly stained, with a darkly stained nucleus at the cell's periphery.
What is a plant cell?A plant cell is a eukaryotic cell with something like a true nucleus and organelles that perform specific functions. However, some organelles found in plant cells differ from those found in other eukaryotic cells.
