Answer:

Option A, Key stone

Explanation:

A keystone species plays a major role in an ecosystem as it is the species whose presence effects all other species in the ecosystem .In general a keystone species is always a dominant predator that feed on prey population. If it is removed, the prey population will explode and the population diversity will reduce. For example - bison, prairie dog etc.  

Hence, option A is correct

Alenkasestr [34]

Answer: Food storage

Explanation:

Stomach is a small pouch like structure which has the ability to store food temporarily.The storage of the food temporarily takes place in the stomach. The food that we eat reaches to the stomach by the help of food pipe.

Here, the food is stored until it is completely broken down into simpler form and enzymes act on them.

The food is then absorbed in the small intestine. But before this food is temporarily stored in the stomach where all the digestive juices and enzymes come to act on the food.

The magnitude of an earthquake is a number that represents the what
Llana [10]

One useful point about the moment magnitude scale is that it is logarithmic, where each whole number represents a factor of 32. Therefore, the difference in two whole numbers of the magnitude means that an earthquake is 1,000 times stronger. For example, a 7.0 magnitude earthquake releases 1,000 times more energy than a 5.0 one.

Metabolic pathways can be controlled through the availability of enzymes and modulation of their catalytic activities. Enzyme av
postnew [5]

Answer: a) substrate and cofactors b) covalent modification

Explanation:

Metabolic pathways involve all the chemical processes takes place in the enviornment or in an organisms.The metabolic pathways are controlled through the catalytic activities of enzymes.

The availability of enzyme is regulated  by substrate and cofactors present in enzyme and enzyme activity is commonly regulated via covalent modification.

Enzymes are highly selective in nature and bind to a specific substarte only. The active site in enzyme binds with the substrate to form enzyme substrate complex. Coactors assist the enzyme activity, without cofactor enzyme can not perform its activity.

Hence enzyme availibility is regulated by  substrate and cofactors regulates.

Covalent modifications regulates activity of enzyme as it involves addition and removal of chemical group to synthesis required protein. It can change the chemical properties of the site by targeting one or multiple amino acid.

Thus the correct answer is a) substrate and cofactors b) covalent modification
