What is Connective tissue? Also provides its functions

Connective tissue: Connective tissue is mesodermal in origin and form of matrix, fibres and cells. It constitutes the extracellular ground substance and fills up the intercellular spaces between the cells. Functions of Connective tissues: Connective tissue is basically a binding and a packaging tissue but has many other important functions as well- A type of connective …

What is Hybridization? Give its uses and describe different types of hybridization in Plants.

Hybridization in Plants: Hybridization is the method of producing new crop varieties by crossing two genetically different parents. As a result of hybridization, the desirable characters of two or more species or varieties are combined together or are transformed from one to the other. Hybridization increases genetic variability. Uses of Hybridization: The main purpose of hybridization …

What is Genetic load?

Genetic load: Genetic load is a measure of the number of disadvantageous genes in a population or of the damage done to the population by certain genetic factors. Disadvantageous genes reduce fitness by mortality, morbidity or sterility in heterozygotes, if the gene is dominant and in homozygotes, if it is recessive. Thus, it is related to …

Structure of Phospholipid and their arrangement in Cell membrane

Structure of Phospholipid: Phospholipids are the triglyceride lipids where one fatty acid is replaced by phosphoric acid, attached to additional nitrogenous group like choline in lecithin phospholipid. The two fatty acids hydrocarbon chains and glycerol functions as hydrophobic (water-repellant) and forms the non-polar tail of the phospholipid molecule; whereas phosphate and nitrogenous compound, choline functions as …

Write a short note on Respiration?

Respiration: Respiration is the process of taking oxygen into the cells, using it to release energy from the digested food and eliminating the waste products (carbon dioxide and water). Respiration involves two main processes: Breathing or External Respiration: The process of taking in oxygen-rich air from the surrounding medium and giving out carbon dioxide-rich air into …
