Answer:
somites
Explanation:
Embryonic development looks like a chronometer. Next to the future spine, cells are differentiated with a certain spacing that scientists call "somites." These are structures that grow, change shape. Somites will give rise to vertebrae, ribs, and axial musculature.
Somites are transient epithelial structures. These structures form early in embryonic development and originate with other important structures in the vertebrate organism.

Answer: The correct answer is D) Some energy in each trophic level is used for life processes.
Food chain represents the flow of energy through various living organisms (which lie at different trophic levels) in an ecosystem. The energy flows from one trophic level to the next and it is decreased with subsequent trophic levels.
As per the law of 10% energy transfer, only 10 % of the energy is transferred from one level to the next as the rest of the energy at every trophic level is utilized in various metabolic processes like respiration, digestion, excretion and also liberated as heat in the surrounding.
Due to this, the energy available at any trophic level is less than the previous trophic level.
D) Endocytosis is a transport mechanism that utilizes energy.
Endocytosis is an active transport, a biological process in which <span>molecules from outside the cell (proteins for example) are passed through the cell membrane and put into the cell. This process requires energy.
The other transport mechanisms, osmosis, diffusion and facilitated diffusion are processes that do not utilize energy. </span>
