Structural, Characteristics, Functions and Location of Connective Tissue . Structural Characteristics: The. amount of matrix is more in connective tissue but the number of cells is comparatively less. Matrix may be jelly like, soft or hard and fragile. One or more than one type of fibre and materials like calcium carbonate may remain present in matrix (Fig-5.6): Functions : Connective tissue connects muscle with muscle and bone with bone. Connective tissue may transform into skeletal tissue, fibrous tissue and. fluid connective tissue. On the basis of structure and function connective tissue is mainly of three types. As: A . Films Connective Tissue: This type of connective tissue lies below the body-integument and sparsely in muscles. In their matrix numerous fibres are present. B. Skeletal Tissue: Internal structural building tissue of the body is called the skeletal tissue. Functions : 1. This tissue forms the internal structure of the body, e.g. skeletal system. 2. It gives the b...
Male-Female determining chromosome: @@@$ IMPORTANT@@@ READ THIS Every living being has a definite number of chromosomes. In human beings there are 23 pairs of chromosome. Among them 22. pairs are similar in both male and female, these are Autosomes, AA. Members of the remaining pair of chromosome are different in male and female. This pair of chromosome determines the sex of human beings. As they determine the sex, so they are called X and y sex chromosome or sex determining chromosome. One of the sex chromosomes is X chromosome and the other is Y chromosome. If the sex chromosome pair is XY, the child will be male (son), and if it is XX, the child will be female (daughter). In Drosophylla (a fly) also XX indicate female and XY male. So in case of determining the sex, the role of X and Y chromosome is vital. Whether the child will be a son or daughter: Now we will discuss whether the father or mother is responsible for the birth of a son or daughter. Both male and female have 44 autos...
