Answer:
A. Because energy is lost at every level.
Explanation:
energy decreases as it travels from lower levels to upper levels--which is a logical observation you could make.
Think of it like this--if a fish eats a small organism, it will then spend some of the energy obtained from the organism swimming around--so when a larger fish eats our fish, the energy from the original organism will already be partially lost (from our fish swimming around).
This means that when this pattern continues over multiple levels, we keep losing energy--which limits the environment's capacity for organisms to survive.
Hope this helps, have a lovely day :)
Answer:
When the cell cycle is interrupted, apoptosis occurs.
Explanation:
Opoptosis is also known as programmed death of the abnormal cell. When cell DNA is damaged first it is repaired. If cell DNA cannot be repaired so the cell kill itself. If Opoptosis didn't occurs, then the cell divides with the damage DNA and transfer that damage DNA to the daughter cells which lead to cancer disease. Cancer also occurs when uncontrolled division of cells is done.

Answer:
The option which does not describe the generalizations in the cerebral cortex is <u><em>b. The hemispheres are exactly equal in function.</em></u>
Explanation:
The cerebral cortex is an exclusively grey matter which makes 40% of the mass of the brain. It has areas for motor neurons and sensory neurons to enter into it and it controls actions like thinking, understanding etc.
The cerebral cortex has two hemispheres; the left hemisphere and the right hemisphere. Each side has different functions to perform.
The cerebral cortex is divided into four lobes and each lobe performs different functions.
