Explanation / Answer

1. Option C. Peptidoglycan forms a mesh like layer outside the cell wall of bacteria.

2. Option C. Human plasma protein includes fibrinogen and immunoglobulin. The Fibrinogen is a glycoprotein that helps in the formation of blood clot in humans. The Immunoglobulin are the class of proteins present in the serum and cells of immune system, which functions as antibodies.

3. Option A. The Alveolate is the member of Alveolata, large assemblage of protists. The alveolates are characterized by system of sacs beneath the cell membrane includes ciliates, foaminiferans, dinoflagellates and apicomplexans.

4. Option B. It is through the mycelium that a fungus absorbs nutrients from its environment.It does this in a two stage process. Firstly the hyphae secrets the enzymes onto food source, which breaks down the polymers into monomers. These monomers are absorbed into the mycelium by facilitated diffusion and active transport.

5.Option B. MSH is acronym for melanocyte stimulating hormone. It is secreted by pituitary gland and function sin skin darkening.
