Answer:
4
Explanation:
Because most of these organisms are autotrophs meaning they make their own food from abiotic factors. Organisms higher up the food chain are heterotrophs meaning they feed on other organisms for energy. Organisms at lower trophic levels usually have higher biomass (in higher population numbers) than higher organisms. This is because of the inefficiencies of passing energy up the food chain.
C5-T1 (cervical 5, 6, 7, 8, and thoracic 1 spinal nerves) comprise a network called the Brachial Plexus, literally meaning "arm network."
This plexus controls both sensory and motor function of the entire upper extremity (shoulder, arm, forearm, wrist, and hand).
Answer: 4, 3, 2, 1
Explanation:
Microtubules originate near the nucleus of animal cells, and the positive ends project outward.
Dynein would be used for moving melanosomes back to the nucleus in light-colored cells.
Kinesin would be responsible for moving melanosomes outward to generate dark-colored cells.
The melanosomes move along microtubule tracks using motor proteins.
