Answer 1

Answer

1. Option A) Hemispheres of the brain

• Midsagittal section divides the body into right and left halves.
• Hence, it seperates right and left hemispheres of the brain.

2. Option D) Regulates movement of materials in and out of the cell

• Plasma membrane is made up of phopholipid bilayer.
• It is selectively permeable.
• Hence, it regulates the movement of certain substances in and out of the cell.

3. Option C) Connective tissue is designed to support, protect and bind organs/structures

• Connective tissue is made up of protein fibers as cells that secrete these fibers.
• The fibers provides strength to the tissue.
• It helps in binding the structures together.
• It also functions to protect underlying tissue.

4. Option A) It produces vitamin D which is important for calcium absorption.

• Skin produces vitamin D when exposed to sunlight using the UV rays.
• Vitamin D plays a major role in calcium absorption.
• Hence, it is very important fore bone health.
