- A.
Hydrogen
- B.
Nucleus
- C.
Membrane
- D.
Protoplasm
Correct Answer
C. MembraneExplanation
The outer covering of a cell is known as the membrane. The cell membrane is a thin, flexible barrier that surrounds and protects the cell. It controls the movement of substances in and out of the cell, allowing nutrients to enter and waste products to exit. The cell membrane also plays a role in cell signaling and communication with other cells. It is made up of a phospholipid bilayer with embedded proteins, providing structural support and maintaining the integrity of the cell.Rate this question:

The six functions of epithelial tissue are______________________________________________.
Correct Answer
diffusion,excretion,absorption,secretion,sensation,protectionExplanation
Epithelial tissue serves several functions in the body. It allows for the diffusion of substances across its surface, facilitating the movement of molecules in and out of cells. It also plays a role in excretion, helping to eliminate waste products from the body. Epithelial tissue is involved in absorption, allowing for the uptake of nutrients and other substances from the external environment. Additionally, it aids in secretion, producing and releasing various substances such as hormones or enzymes. Epithelial tissue is also responsible for sensation, as it contains specialized cells that can detect stimuli. Lastly, it provides protection, acting as a barrier against physical, chemical, and microbial damage.Rate this question:

Two properties of Nerve tissue are_______________________________
Correct Answer
excitability ,conductivityExplanation
Nerve tissue is characterized by two main properties: excitability and conductivity. Excitability refers to the ability of nerve cells to respond to stimuli, such as chemical signals or electrical impulses. This allows nerve cells to generate electrical signals, known as action potentials, in response to these stimuli. Conductivity, on the other hand, refers to the ability of these electrical signals to travel along the length of the nerve cell and transmit information to other cells. Together, these properties enable nerve tissue to play a crucial role in transmitting and processing signals in the nervous system.Rate this question:
- 11.
What are the supporting cells for nerve tissue called____________________________
Correct Answer
neurogliaExplanation
Neuroglia, also known as glial cells, are the supporting cells for nerve tissue. These cells provide structural support, insulation, and protection to neurons in the nervous system. They help maintain the overall health and functioning of neurons by regulating the extracellular environment, providing nutrients, and removing waste products. Neuroglia also play a role in repairing damaged neurons and forming scar tissue. Overall, neuroglia are essential for the proper functioning of nerve tissue.Rate this question:
- 12.
