Answer:
Trees maintain the air quality by the process of
Explanation:
Tress removes the carbon dioxide and it adds oxygen which maintains the balance of the gases in the atmosphere, during the process of photosynthesis which maintains the quality of the air we breathe.
Carbon dioxide is removed from the atmosphere by the trees when they perform photosynthesis, which helps to reduce the greenhouse effect which is caused because of the high level of carbon dioxide present.
They also remove the particulates matter present in the air, which maintains the air quality.
Thus these are some ways by which trees help to maintain the air quality.
a. global warming
b. oil spill
Answer:
its B I took the quiz
Explanation:
Answer:
False.
Explanation:
The food chain may be defined as the sequential tropic levels in which the organism eat other organisms and itself being eaten by other organism. Food chain do not exist in nature.
According to the 10% energy law, the energy is lost from one tropic level to the another tropic level. The 10% energy is available to the next tropic level and the remaining amount of energy is lost as heat. No energy gain occurs as the transfer of energy takes place from the producer to consumer.
Thus, the answer is false.
grass > rabbit > snake > hawk
The basic function of the nervous system is to send the signal from one organ to other organs with the help of neurons.
In this system, It includes:-
All these unit help to transfer the singal from sensory organ to target organ. To perform an action, stimulus is required.
The unit in which Motor neuron and all of the skeletal muscle cells recives the stimulates is called a motar unit.

The Action potential is the electrical signal that typically moves from the cell body down the axon to the axon terminals.
An Axon terminal may be defined as a region that is typically found at the end of a neuron after the termination of axons. This region is a small, spherical, bouton-like structure. It is also known as terminal boutons.
An action potential is a rapid and transitory alteration in the resting membrane potential. This potential significantly involves the alteration in the electrical potential which is associated with the passage of an impulse.
Such types of potentials are only stimulated by neurons and some muscle cells. This property of action potential is also known as excitability.
Therefore, the electrical signal that typically moves from the cell body down the axon to the axon terminals is known as the action potential.

Answer: Action potential
Explanation:
Action potential is the electrical signal that typically moves from the cell body down the axon to the axon terminals. There are other terms to refer to this, and those are impulse or spike. This is so because action potential is created when "the membrane potential of a specific axon location rapidly rises and falls," according to its definition.
