Explanation:
Answer:
B. VESSELS, HEART, CIRCULATING FLUID.
Explanation:
Blood is the circulating fluid. It is the connective tissue of liquid plasma and cells.
Heart is a muscular pump to move the blood and have it circulate throughout the body of living animals.
Blood vessels are arteries, capillaries and veins that deliver blood to all tissues.
The Circulatory System has two types. They are the open circulatory system and the close circulatory system.
An open circulatory system is one where the blood does not circulate inside blood vessels but also flows into cavities that irrigate tissues.
A close circulatory system is one where the blood circulate only inside the blood vessels.

A, B, and C make no sense
A makes no sense because Methane is lighter than air, and so the Methane would stay higher in the atmosphere, so it would not seep into the ground, it would remain in the air.
B makes no sense because Burning fossil fuels causes air pollution by increasing the amount of carbon dioxide in the air. the only way that carbon dioxide could pollute water is if it is combined on a molecular level, plus carbon dioxide does not inhibit the process of water being evaporated by the sun.
C also makes no sense because Deforestation causes acid rain by increasing carbon dioxide not decreasing carbon dioxide in the atmosphere.
so therefore by elimination your answer is D

Explanation:
Explanation:
The main activity that occurs at the transmissive segment is the release of neurotransmitter from synaptic vesicles . Prior to the arrival of the action potential, Ca2+ pumps embedded in the plasma membrane of a synaptic knob establish a calcium concentration gradient by pumping it out to the IF. Consequently, there is more calcium inside of the synaptic knob than outside it.
Further Explanation:
At synaptic junctions:
- The action potential travels along the membrane until the synapse where it’s electrical depolarization leads to the opening of channels allowing Ca2+ to rush into the terminal due to higher extracellular concentrations
- these flow through a presynaptic membrane until the concentration is built up, activating ion sensitive proteins attached to vesicles containing neurotransmitters
- this leads to changes in the proteins leading to the fusion with the membrane of the presynaptic cell, so vesicles are open and neurotransmitter is released. The neurotransmitter diffuses across to chemical receptors on the presynaptic cell where they bind temporarily
- This leads to activation of specific complexes, enabling the transmission of information. Thus, the chemical signal is transferred through this neuron as an electrical impulse
