Why are groups of small cells better than one large cell at moving material in

Biology
1 answer:
quester [9]3 years ago
5 0

Answer:

C. They have a greater surface-to-volume ratio.

Explanation:

Because these smaller cells can access and pass through the membranes of the other cell membranes and permeable coverings easily and voluntarily unlike larger cells. It is also efficient for these smaller cells to penetrate and travel, delivering and transporting goods and materials such as nutrients, oxygen and waste throughout the body without consuming enough energy and conserving lesser space.

For simple reasons, they are faster, more efficient and consumes little space, and most especially depletes lesser energy. So, many small cells have more surface area than one large cell.

Elastic fibers are important to muscle tissue since they resist excessive stretching and help muscle fibers spring back to its o
brilliants [131]

Answer:

True

Explanation:

Elastic fibers are composed of elastin, myofibrils and fibrillin. They are distributed <u>separately</u>, and therefore do not form bundles(they actually form a kind of mesh), like collagen fibers.

Elastic fibers are usually thin and long and can stretch up to 1.5x of their total length.

These fibers confer elasticity to the connective tissue. The mesh formed of elastic fibers easily yields to minimal tensions, returning to its original shape as soon as the deforming forces cease.

An example of the action of elastic fibers is when we pull the skin from our hands and release it, the elastic fibers are responsible for quickly returning the skin to its original shape.

Sensory receptor cells convert a stimulus, such as an odor molecule or light, into an electrical signal that is conveyed to the
swat32

Answer:

Sensory transduction.

Explanation:

Sensory transduction may be defined as the process by which sensory stimulus are transformed in the body. The receptor cell is mainly involved in the sensory transduction process.

The sensory receptor cell like a light or an odor is converted into the electrical signal by the process of signal transduction. The information is then conveyed to the nervous system in the form of electrical signals.

Thus, the correct answer is signal transduction.
