The gases must also be exchanged between the blood capillaries and the cells of the body. This is called internal respiration

Answer:

Take two potted plants and provide equal conditions to both.

Explanation:

Two potted plants i.e. one is placed near the nuclear accident site while on the other hand, the other is placed far away from the nuclear accident. Provide equal conditions to both plants so that we can find out the hypothesis that  the frequency of mutations decreases with the organisms distance from the source of radiation. The result shows that the potted plant that is located near to the nuclear accident site having high frequency of mutation as compared to other plant due to the radiation present at that location.

What is the primary product of light-independent reactions?
Alina [70]

The correct answers are;

A.) High energy sugars

A) ATP

The light-independent (dark) reactions are chemical reactions of photosynthesis which occurs within the stoma in plant chloroplast. These reactions use the products of light-dependent reactions which are ATP and NADPH with some enzymes (such as RuBisCO) to carry out its processes. Carbon dioxide and other compounds are converted to produce high energy sugars (glucose) which is used by the plant.

Glycolysis is the cellular degradation of the simple sugar (glucose) to produce pyruvic acid (also known as pyruvate), and ATP (adenosine triphosphate) is used as an energy source.

vampirchik [111]

Answer:

The somatic nervous system

Explanation:

The peripheral nervous system is categorized into two types: the autonomic and somatic nervous system.

The somatic nervous system controls the voluntary actions of the boys so is also known as the voluntary nervous system and the voluntary system involves the skeletal muscles therefore is also known as the skeletal nervous system.

The skeletal nervous system contains two types of neurons called the afferent neurons which carries the sensory input from the muscle to the CNS ans the efferent neurons which brings the impulse from the CNS to the muscles.

Thus, the somatic nervous system is the correct answer.
