Explanation / Answer

Ans 29 : ( c ) based on how their secretion is released.

On the basis of the mode of pouring of their secretions, glands are divided into two categories namely exocrine : they are glands which pour their secretion either directly over the substrate or through a duct. e.g ; goblet cells , salivary glands , tear glands , gastric glands, intestinal glands.

And the second is the endocrine gland : they are ductless glands. The glandular secretion directly poured into the fluid bathing the gland and their secreted products are called Hormones

Ans 30 : (c ) Holocrine

The cell filled with secretory products disintegrates during discharge of the product.These glands accumulates their products into cytosol.e.g ; sebaceous glands

Ans 31: ( e ) protein fibres and ground substance

Connective tissue posses a viscous semifluid or semi-solid matrix, a number of fibers and living cells. Matrix is thin, gel -like transparent , intercellular material of structural glycoproteins and glycoaminoglycans.

Ans 32 : ( e ) liver cells

Connective tissues are most abundant and widely distributed in the body of complex animals. It includes cartilages, bone , adipose , blood, tendons , ligaments.

Ans 33 : ( c ) ground substance

Ans 34 ( a) hyaluronic acid
