Epididymis receives sperm from the efferent ductules and sends it on to the Vas deferens.
Epididymis is a structure that forms a connection between the efferent ductules and vas deferens.
Epididymis is a structure that helps in the maturation of sperm and make it functionally mature to carry out fertilization in the human female body. It stores the sperm cells. It matures the immature cells from the testis.
Epididymis is divided into three parts namely:
- Caput Epididymis: Part where sperm enters from testis directly
- Corpus Epididymis: Part where sperm gain motility
- Cauda Epididymis: Part where sperms are stored
Epididymis is an important region of the ductules present in the transportation of sperm out of the testis and towards the urethra of the male body.

Answer: (B) to function as the final electron acceptor in the electron transport chain.
Explanation:
Oxidative phosphorylation is a process that takes place in cellular respiration. It consists of two component pathways which includes the electron transport chain (etc) and chemiosmosis.
In etc the electrons are passed from one to another molecule, the energy is released by the electrochemical gradient.
In chemiosmosis, the energy stored in the electrochemical gradient is used to produce energy molecules in the form of ATP (Adenosine triphosphate).
The oxygen is present at the end of the etc. It's function is to accept the electrons also picks up the protons to form water. If oxygen is absent then no molecule will accept the electrons, the electron transport chain will stop. There will be no chemiosmosis as the ATP will not be produced in the absence of formation of a electron gradient.
Answer:
organic compounds are compounds which have combination of carbon atom in there structure. ex. vitamins, milk, coal etc
inorganic compounds are compounds which don't have any carbon atom in there structure ex. salt, iron, water etc
Answer:
Part of DNA (genetic material)
Explanation:
DNA cloning, as a method in molecular biology, is used for the multiplication of gene (or other piece of DNA). It usually includes steps of DNA insertion into plasmid (prokaryotic circular piece of DNA). That plasmid is than introduced into bacteria via process called transformation.
Answer:
The correct answer is option B.
Explanation:
Homeostasis is the process or mechanism of trying to maintain equilibrium while interaction with the outside world. An example of maintaining homeostasis in the system level would be the endocytosis and exocytosis of a substance.
Endocytosis and exocytosis are the mechanisms in which molecules are brought into the cell and out of the cell depending on their need to the cell.
Thus, the correct answer is option B.
