Active transport moves molecules across the plasma membrane of a cell with the help of transport proteins and energy (ATP).
Active transport is the means of transport of molecules across the plasma membrane with the help of energy. This method is usually used for the transport of molecule against their concentration gradient, i.e., from lower concentration to higher concentration.
Plasma membrane is the outer layer surrounding the cell. It is made up of lipid bilayer, proteins, carbohydrates and cholesterol. The lipid bilayer is amphipathic since the lipid head is hydrophilic and its tail is hydrophobic. The plasma membrane is semi-permeable in nature.

Explanation:
Answer:
We usually categorize senses into 5 main groups: Touch, Smell, Taste, Sound, and Sight. All of these senses are detected by different types of nerves in different areas of the body. The cardiovascular system allows the brain to communicate with these nerves and receive signals from them. If the cardiovascular system isn't working properly, the brain cannot communicate with the body's nerves.
The human integumentary system in body helps regulate body temperature through its compact association with the sympathetic nervous system (SNP), the division of the nervous system involved in our fight-or-flight responses. Hair can be curly, strait, or wavy, it can also be rough, smooth or silky. But the main function of the hair is to cover or insulate our body. It helps regulate body temperature. It also diverge a person's sweat or perspire.
<h3>
What is sympathetic nervous system?</h3>
The sympathetic nervous system is constant monitoring body temperature and start appropriate motor responses.
For example, the sweat glands, accessory structures of the skin, release water, salt, and other substances to cool down the body when it becomes warm.
