ipn [44]

Cloning is a process of producing genetically identical organisms through the techniques of biotechnology. Reproductive cloning of animals involves the somatic cell nuclear transfer in which the nucleus from an adult donor cell is transferred to an egg cell from which the nucleus has been removed. It is then incorporated into the uterus of a surrogate animal.

Pet cloning is not acceptable because of the following reasons-

(1) Its a very expensive procces with a high rate of failure.

(2) The clones produced tend to develop health problems. Large Offspring Syndrome (LOS) with very large organs is observed showing problems with blood flow and breathing with respect to heart and lungs, renal failure and other complicated issues.

(3) The clones are susceptible to skeletal abnormalities, higher rates of infection and tumour development. This results in a high mortality (death) rates.

(4) Since a surrogate mother is involved in the process of cloning, they experience a lot of health problems while carrying the embryos and sometimes it can be even killed.

Thus, cloning of pets is not acceptable as it affects both the cloned animal and the surrogate mother which is not preferred. Instead, adopting a homeless pet will provide shelter to another animal with a better nourishment.

The regulation involves a different type of endocrine hormones and thyroid gland and receptors that help in signaling the increase or decrease of body temperature it involves neurons and hormones.

Due to the response of thermoreceptors and hormones is known as the neuroendocrine response. Hypothalamus Involves two or more hormones and several steps it known as a complex response.

Thus, the correct answer is a Complex neuroendocrine response.
