Biological Classification

Answer (a) cow
Bovine spongiform encephalopathy is also called mad cow disease and is a transmissible neurodegenerative disease that will affect the cattle. The prior proteins are abnormal. The mode of transmission is by consumption of cattle products that are contaminated by infected nervous system tissues. They can be easily transmitted to humans and prevention measures are taken. This includes the removal of specified risk materials from the cattles.

Let's match each compound from Column I with its correct function from Column II:

Trypsin: This is an enzyme involved in the digestion of proteins, breaking them down into smaller peptides.

• The correct match is: 1 → r (Works as an enzyme).

GLUT-4: This is a glucose transporter protein found in muscle and fat cells that facilitates glucose uptake into the cells.

• The correct match is: 2 → s (Enables glucose transport into cells).

Collagen: This is a structural protein found in connective tissues, serving as an intercellular ground substance and providing strength and support to tissues.

• The correct match is: 3 → q (Is an intercellular ground substance).

Antibody: These are proteins produced by the immune system that help fight off infectious agents like bacteria and viruses.

• The correct match is: 4 → p (Fights infectious agents).

Correct Matching:

1 → r (Works as an enzyme)

2 → s (Enables glucose transport into cells)

3 → q (Is an intercellular ground substance)

4 → p (Fights infectious agents)

The correct answer is (D) : 1-r, 2-s, 3-q, 4-p.
