Any change in non-reproductive tissues cannot be passed on to the DNA of the germ-cells. therefore, the traits acquired during life-time of an individual are not inherited.

Contraceptive methods should be adopted as: . They help in spacing two children. . Thus helps in maintaining a woman's and child's health. . Better care and healthier society. . Also prevention of sexually transmitted diseases on using condoms. . More productivity and hence better economic status.

Since we are mammals, the development of growing foetus takes place inside the mother's womb. Thus, during each cycle, the uterus prepares itself for implantation by increasing blood flow and thickening of uterine walls. In case, fertilisation does not take place, the thickened wall is not required,Read more

In case, fertilisation does not take place, the thickened wall is not required, it thus is shed along with blood and mucus in the form of menstrual flow.
(i) Plant raised by vegetative propagation can bear flower and fruits earlier than those produced from seeds. (ii) It also helps in propagation of plants such as banana, orange, rose and jasmine that have lost the capacity to produce seeds. (iii) All plants produced by this method are genetically siRead more

(ii) It also helps in propagation of plants such as banana, orange, rose and jasmine that have lost the capacity to produce seeds.
(iii) All plants produced by this method are genetically similar to the parent plant to have its all characteristics.
(iv) Thus, desirable features of parent plant can be retained and expressed without any change future generations.
Diabetes is caused due to deficiency or less secretion of insulin by pancreas. In such person, the blood sugar level is high. Function of insulin is to convert excess sugar present in blood into glycogen. Patients suffering from diabetes are thus given insulin injection to control their blood sugarRead more
