Answer:The seminal vesicles produce mucus to neutralize the acidic environment of the vagina.
Explanation:
The seminal vesicles is found in male reproductive system which produces mucus that is alkaline in order to protect the sperm from the acidic environment of the female vagina . This also contain sugar to nourish the sperm.
The vargina is the outer opening of female reproductive system that receives the sperm. It is acidic in nature because it discharge fluids that contain liquid, cells and bacteria that lubricate and protect it.
A single gene could be inserted into a plant's genome, enabling specific traits to be expressed easily. Scientists have identified genes for two enzymes needed to make pro-vitamin A. One of these genes comes from corn.
Answer:
structures that preform many jobs in cells :)
Answer:
B) astrocytes
Explanation:
Cells other than neurons that play an important role in the normal functioning of nervous system are called Neuroglia or glial cells.
Satellite cells, astrocytes, schwann cells and oligodendrocytes are all examples of glial cells.
⇒Satellite cells provide protection and nutrition to cells in peripheral nervous system ( peripheral nerves and ganglia).
⇒<em><u>Astrocytes</u></em> play an important role in central nervous system (brain and spinal cord). They provide protection to neurons, scavenge ions, form the blood-brain barrier and also maintain extracellular environment suitable for neuronal functioning.
⇒Schwann cells are found in the peripheral nervous system and myelinate the axons of neurons.
⇒Oligodendrocytes are found in central nervous system and produce myelin sheath which myelinates (insulates) axons of neurons. Their function is similar to schwann cells but in the central nervous system.
From the above discussion it is clear that the answer is B) Astrocytes as these maintain a suitable chemical environment for the neurons.
