Answer:
Nervous system
Explanation:
The nervous system in humans work together to collect information about the external environment because they consist of the brain, spinal cords and neurons. They collect information from external environment and those information travels through neurons from sense organs like eyes, ears, skin e.t.c as a form of electrical impulses. When they get to the end of the neuron, a chemical called neurotransmitters are released which travels across the cells and send it to the brain, the brain then process it and interprete the signals and respond to it as stimulus.
No bc Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP<span>). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called </span>aerobic respiration<span> and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.
