RNA and DNA are nucleic acids, and, along with lipids, proteins and carbohydrates, constitute the four major macromolecules essential for all known forms of life. Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA, RNA is found in nature as a single strand folded onto itself, rather than a paired double strand.

What is the thin layer of endothelial tissue that lines the inner surface of the heart and the valves called
serious [3.7K]

Answer:

Endocardium

Explanation:

The endocardium makes the innermost lining of the wall of the heart. It is present over the thin layer of connective tissue. The function of the endocardium is to provide a smooth lining for the chambers of the heart. The valves present in the heart also have endocardium. The dense connective tissue of the heart valves is covered by endocardium.

The presence of the smooth endocardium made up of endothelium reduces the surface friction as blood passes through the heart. The endocardium of heart chambers is continuous with the endothelial lining of the large blood vessels that are attached to the heart.

12. Recent developments have resulted in the ability to clone cats. Many people argue that cloning offers pet owners comfort in
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.
