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.

7. How does the plant lichen quicken the weathering process? *
34kurt

Answer:

The correct answer is - They secrete acid that breaks away rocks

Explanation:

Lichen causes chemical weathering to break the rocks quickly which is the excretion of various acids like oxalic acid and many more organic acids that can cause a significant impact on the rock by dissolving minerals.

By breaking the rocks it forms the ground for the plant that will come later in place of the bare rocks by this chemical weathering process. An example of chemical weather is a change of the granite to clay with the help of hydrolysis.

What is the end result of the electron transport chain?
WARRIOR [948]

Answer:

The end result is Water and ATP.

Explanation:

Electron transport chain is the stage of cellular respiration. Four protein complexes in the inner mitochondrial membrane form the electron transport chain. These complexes exist in a descending order of energy. The electron carriers come along to drop off all their electron and proton cargo that they picked up during the glycolysis and citric acid cycle stages.he electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP). ATP is used by the cell as the energy for metabolic processes for cellular functions.

Nutka1998 [239]

Answer:

1. D. Only DNA contains genetic information

2. D. Nitrogen and Phosphorus

Explanation:

1. Lipids are insoluble in water unlike other molecules. It stores energy within the fat tissues and cushion internal organs against trauma.

Carbohydrates are sugar units such as monosaccharides, disaccharides molecules which makes up starch that is fuel to your cells.

DNA is a type of nucleic acid that contains genetic information which influences your personal characteristics.

2. The family Rhopalodiaceae has the ability to perform nitrogen fixation, which allows diatoms to fix atmospheric nitrogen. And phosphorus has been found in some diatom species in the Black sea region which does not affect its reproduction rate and also helps in carbon cycle.
