Why does the seed of maize germinate into maize plant but not into millet plant? Why does a dog give birth to puppy but not the piglet? How do characters of parents gets transmitted to offspring from generation to generation? Body of all living organism is made of large number of cells. Each cells consists of nucleus. Thread like substances are present in nucleoplasm of nucleus. These thread like substances are called chromosomes. These chromosomes are responsible for the passing of characters from parents to offspring. Each chromosomes contains large number of genes. Because of the genes present in chromosomes characters of the parents get transmitted into offspring. These genes are made up pf DNA (Deoxyribonucleic acid).

Human Blood Definition, Functions, Parts , Types, Blood pressure, Blood circulation, etc. Blood The blood is fluid connective tissue. It is viscous and red in colour. It carries nutrients, hormones and oxygen to all the parts of the body and helps to eliminate the waste materials from our body. The blood is mainly up off plasma and blood corpuscles. •  Plasma It occupies about 55% of the blood. It is transparent yellowish liquid. It contains 90% water and rest 10% of solid protein, fat, salt, carbohydrates, antibodies, etc. Functions of plasma - It transports digested food nutrients dissolved in water which diffuses through the intestine. - It carries carbon dioxide liberated during respiration from the cell or tissues to lungs. - It carries waste materials released from tissues to the related excretory organs. - It transports the hormones secreted by endocrine glands to the tissue of related site. - Fribinogen protein present in plas...

NERVOUS SYSTEM AND BRAIN The organ system comprising brain, spinal cord and nerve tissues is called nervous system. The nervous system is responsible for control and coordination of the body. In nervous system, the electric signals are generated in the form of nerve impulses which are usually associated with the fast response to the envision of mental stimuli. The nervous system performs following function. • It helps to get information of change in environment through sense organs. • It makes the body capable of conduct involuntary activities such as breathing,  rhetoric, contraction and expansion of heart. • It helps to regulate voluntary activities of the body i.e. movement of different parts of the body while doing work. • It helps in remembering, thinking, reasoning, etc Nervous system are basically divided into three divisions. a. Central nervous system b. Peripheral nervous system c. Autonomic nervous system Central Nervous system (C...
