Why must cells divide to stay small or change shape to reduce volume?

Biology
2 answers:
stepan [7]3 years ago

Answer:

if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.

Answer:

To ensure the cell is able to obtain nutrients or remove wastes.

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume That is why cells are so small.

Red flowers (dominant) crossed with white flowers (recessive) can yield pink flowers. Pink is the heterozygous condition in a trait that shows incomplete dominance. If pink flowers are crossed with white flowers, assuming random chromosome segregation, what percentage is expected to be red flowers?

RR x rr= Rr, Rr, Rr, and Rr

Red x White= Pink heterozygous

Rr x rr= Rr, Rr, rr, and rr

Pink x White= 0% as both Pink and white shares it with 2:2 or 50:50%

How do changes in the atmosphere from burning fossil fuels affect plant life? Select two correct answers
german

Answer:

I'd Say A because it talks about slowing down the plants and removing stuff from the soil.

Which section of the brain is responsible for coordinating muscle movements
jarptica [38.1K]

Answer:

The cerebellum (back of the brain) and the brainstem (middle of the brain)

Explanation:

Muscle movement coordination can be<em> voluntary</em> or <em>involuntary</em>. There are different sections of the brain responsible for the two;

  • Voluntary movement of muscles is coordinated by the brainstem in addition to other functions such as sneezing, swallowing, vomitting, etc.
  • Involuntary coordination of muscles is controlled by the cerebellum in addition to maintaining posture, balance and body equilibrium.

Hence, both the cerebellum and the brainstem are responsible for coordinating muscle movement.

What are the responsibilities of the region of the brain highlighted below?
spayn [35]

That part of the brain is specifically used for expressing language, so I would say "<u>Controlling voluntary body movements, processing information from sense organs, thoughts, and learning abilities.</u>" Is the answer. It's known as the Bronca's Area.
