) An allosteric interaction between a ligand and a protein is one in which: (3 pts) A) binding of a molecule to a binding site affects binding of additional molecules to the same site. B) binding of a molecule to a binding site affects binding properties of another site on the protein. C) binding of the ligand to the protein is covalent. D) multiple molecules of the same ligand can bind to the same binding site. E) two different ligands can bind to the same binding site.
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.

Why are fungi more like animals than plants?
PLEASE HELP ME
Answer:
Hey mate.....
Explanation:
This is ur answer.....
However, unlike plants, fungi do not contain the green pigment chlorophyll and therefore are incapable of photosynthesis. That is, they cannot generate their own food carbohydrates by using energy from light. This makes them more like animals in terms of their food habits.
Hope it helps!

6.Explain how animals in Vertebrata are classified into further subgroups.
Answer:
Vertebrates are further classified according to several criteria like exoskeleton, respiratory organs, method of giving birth, number of chambers in heart, mode of living etc. They are further classified into classes Pisces, Amphibia, Reptilia, Aves and Mammals
why us a spirogyra called a thallus ? which types of nutrition does it show ?why?
Explanation:
a plant body that is not differentiated into stem and leaves and lacks true roots and a vascular system. hence spirogyra called a thallus.
Spirogyra is an example of Green algae , thus it prepare its own food by process of photosynthesis in presence of sunlight and chlorophyll.So, its nutrition type is Autorophic.
Use the drop-down menus to complete the hypothesis of the first group of researchers. During a drought, the decrease in rainfall will reduce the amount of vegetation that can grow and increase the occurrence of natural fires, so an elevation in Select… and a reduction in Select… should be found in the cores.
Answer:
Microscopic charcoal, Vegetation.
Explanation:
As the researchers conducting research in the Nile region identified that an increase in temperatures leads to an increase in droughts and reduction of natural vegetation and thereby the chances of the occurrence of natural fires.In the 1950s the structure of DNA was discovered by using models and x-ray chromatography currently science has used advanced technology to completely map out the genes in a human's body. What would be the best advantage of using this information?
Answer:
Gene therapy to correct defective genes that cause diseases.
Explanation:
Gene therapy refers to the procedure that involves the introduction of nucleic acids (DNA or RNA) into the cells of an organism for the purpose of correcting abnormalities, such as a mutations or in other words to treat a genetic disease.Gene therapy entails bringing a normal and functional gene known as a trans-gene into a cell with altered gene. Another method can bring RNA capable of partially regulating or blocking the expression of an altered gene.The nucleic acids are introduced into the patient's cells by means of a viral vector or injected directly into the cells in the form of naked DNA.pls mark brainliest

The Channel Islands are a series of small islands off the California coast. Each island has a genetically distinct population of foxes. Compare the population of foxes on one of these islands to the population of foxes in the forests of mainland California. Which is more likely to be impacted by genetic drift? Which is more likely to be at Hardy-Weinberg equilibrium?
Answer:
The fox population on the Islands experiences genetic drift whereas foxes in the forests has Hardy-Weinberg equilibrium.
Explanation:
The fox population on the Islands experiences genetic drift because there is no chance of introduction of different type of foxes in these Islands which experiences less variation in the population of already existing foxes. Genetic drift is the change that occur in the frequency of an existing gene allele in a population due to random sampling of organisms. Genetic drift may cause gene variants to disappear completely with the passage of time which leads to reduce genetic variation. The foxes that is located in the mainland forest experiences Hardy-Weinberg equilibrium.

define and describe osmosis
Answer:
Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.
Explanation:
Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.
Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.
