Answer 1

Answer:

skin

Explanation:

The skin is vital for our general health and well-being. In addition to acting as the body's first line of defense against bacteria and viruses, healthy skin also maintains fluid balance and helps regulate body temperature. She is very sensitive, she recognizes the slightest touch as well as pain.

As an outer layer that we can see and touch, the epidermis protects us from toxins, bacteria, and fluid loss. It consists of 5 sublayers of keratinocyte cells. These cells, produced in the deepest inner, basal layer, migrate to the surface of the skin. As they do so, they mature and go through a series of changes.

in which direction do particles in a solution move during passive transport

Answers

During the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending. The passive transport is seen in the cell too.

What is the importance of the different types of transportation?

In the cell, different types of transport are seen, such as active transport and passive transport; in active transport, energy is used, while energy is not used in passive transport. The movement of molecules across the cell plasma membrane is important because it allows cells to get rid of unwanted molecules. Passive transport does not require energy, and many nonpolar small molecules and gases can cross the lipid plasma membrane barrier and go into and out of the cell while, in this passive transport process, they save the cell's energy.

Hence, during the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending.
