The answer is (A) Mitochondria have their own DNA molecules, separate from the rest of the cell's DNA.
The endosymbiotic hypothesis concerns with the presence of two special organelles, mitochondria and chloroplast within the eukaryotic cell. These two organelles have their own set of DNA that is different from the nuclear DNA of the eukaryotic cell. It is believed that a primordial eukaryotic cell was in a symbiotic relationship with mitochondria-like bacterium. The primordial cell eventually engulfed the mitochondria-like bacterium for ATP production to power itself.

Answer:
A number of responses occur in the body to the release of neurohormones when the body encounters stress "inhibition of reproductive function"
Explanation:
Neurohormones in the mammals are oxytocin and vasopressin, both of them are produced by the hypothalamic region of the brain and then released into the blood by the help of neurohypophysis. Neurohormones are mostly the chemical messenger which are being released by the neurons, when they enter into the bloodstream from which they can travel to the target sites within body. The hypothalamus starts secreting the substances i.e. neurohormones when it receives the signal from the nervous system.
