Answer:

A- brain + cranial nerves (I'm assuming since they are related)

B- Radial nerve

Explanation:

The cranial nerves are pairs of nerves that connect your brain to different parts of your head, neck, and trunk. There are 12 of them, each named for their function or structure. Their uses are mainly categorized as Sensory and Motor. Sensory nerves are involved with your senses, such as smell, hearing, and touch. Motor nerves control the movement and function of muscles or glands.

The radial nerve controls movement of the triceps muscle, which is located at the back of the upper arm and is responsible for extending the wrist and fingers. It also controls sensation in part of the hand.

Antelopes and elephants feed on the same species of grasses and shrubs in a savanna and the fitness of each species is reduced w

34kurt

Interspecific competition occurs between antelopes and elephants.

The term "competition" refers to the process that takes place among many species as they fight for the same limited resources in order to maintain their own existence. This struggle over resources occurs among organisms because these species occupy niches that overlap, and as a result, they are compelled to use the same resources like food, water, and shelter.

Competition can be either interspecific or intraspecific. The term "interspecific competition" refers to a type of competition that occurs between various species that live in the same biological area and are dependent on the same source of food.

In the question, both antelopes and elephants feed on the same grass and shrub species. Therefore they compete amongst themselves as a result of which their fitness is reduced.

Which of the following can affect the activity of an enzyme?

Gennadij [26K]

The correct option is 3.
Enzymes are biological catalysts which speed up the rate of biochemical reactions inside the cells. Enzymes are very specific in action and they require specific conditions called optimum conditions for them to function optimally.
When the optimum conditions are not met, an enzyme's activity will be lowered or totally stopped.
Conditions that affect the optimum activity of an enzyme include: temperature, pH level and regulatory activity of regulatory enzymes and hormones.
