Biology

Answer: Layers of the Epidermis. The epidermis is the outermost layer of our skin. It is the layer we see with our eyes. It contains no blood supply of its own—which is why you can shave your skin and not cause any bleeding despite losing many cells in the process.

kow [346]

Answer:

Neurons in the parasympathetic division release neurotransmitters that act on receptors that slow heart rate

Stimulating the organs of digestion is a parasympathetic response

Parasympathetic nerves are associated with the cranial and sacral regions of the spinal cord, whereas sympathetic nerves are associated with the thoracic and lumbar regions

The sympathetic division of the PNS prepares the body for physical exertion in stressful situations.

Explanation:

The autonomic nervous system also called the vegetative nervous system is part of the peripheral nervous system which inervates  smooth muscle and glands. Thus, it directly affects the function of internal organs and  regulates  functions such as the heart rate, digestion, respiratory rate,  urination etc. This nervous system control is  unconscious.

The autonomic nervous system is divided into: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.

Parasympathetic nervous system works when organism is at rest so it is known as system responsible for "rest and digest functions". On the other hand, sympathetic nervous system works at active and stressful situations and it is known as "fight and flight" system.

3. Semi-permeable.

4. Passive transport

5. Osmosis.

6. Facilitated diffusion.

7. Active.

8. Endocytosis.

9. Exocytosis.

10. Protein pumps.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Generally, cells have the ability to independently replicate themselves.

In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.

In order for cells to function properly and stay alive, they must be in a state of equilibrium known as homeostasis.

Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.

One way that cells maintain balance is by transporting material in and out of a cell; the cell membrane is the organelle that is responsible for regulating this process. The cell membrane is called semi-permeable which means that the membrane will allow some materials to enter/exit the cell while preventing others. Thus, it is the wall of the cell and typically controls what leaves and enters the cell.

Some materials can easily move across the cell membrane without requiring energy, this is called passive transport and includes diffusion and osmosis, the diffusion of water. Another type of passive transport requires a protein to move larger molecules such as glucose across the cell membrane. This is called facilitated diffusion.

Other particles require energy to move across the membrane because they move against the concentration gradient and against homeostasis; this type of movement is called active transport. An example of active transport is endocytosis where vesicles are formed to move large particles into the cell and exocytosis where vesicles move large particles out of the cell.

This ultimately implies that, exocytosis is a process in which living organisms release or expel large amount of unwanted material through the use of vesicles. Vesicles are cell organelles that ensure materials are properly transported to the right and exact location.

Additionally, exocytosis is a process initiated by the Golgi apparatus because it prepares the material for export by chemically tagging them.

Protein pumps are another example of active transport that moves ions against the concentration gradient using a protein.
