Answer:
B. Electron Cloud
Explanation:
It would not be A because, electrons orbit the nucleus so they cannot be physically IN it.
It cannot be C either because, we are talking about an atom not a cell. Mitochondria is only present in cells.
Unmyelinated axons and neuronal cell bodies make up the majority of the grey matter.
The processes that emerge from the cell bodies of neurons and transmit messages between those cell bodies are known as axons.
These axons are primarily unmyelinated in the grey matter, which means that myelin, a whitish-colored, fatty protein, is not covering them.
In the brain, the grey matter is used to process information. Grey matter structures analyze signals produced by sensory organs or other regions of the grey matter.
This tissue sends sensory (motor) stimuli to the central nervous system's nerve cells, where synapses cause the nerve cells to respond to the stimuli. Through myelinated axons, which make up the majority of the white matter in the cerebrum, cerebellum, and spine, these impulses travel to the grey matter.

<u>Answer:</u>
<em>Decrease in burning of fossil fuels will affect carbon cycle the most.
</em>
<u>Explanation:</u>
Carbon compounds circulate within the biosphere as part of carbon cycle. In terrestrial ecosystems Plants acquire carbon dioxide through photosynthesis and in aquatic ecosystems plankton absorb carbon dioxide.
Dead plants bodies deposited underground for a large number of years get converted to fossil fuels and the burning of these fossil fuels releases carbon dioxide into the atmosphere.
Carbon dioxide is also released into the atmosphere through processes like respiration and decomposition of dead organic matter. If burning of fossil fuels is decreased it will be the carbon cycle which will be affected the most.
