stepan [7]

Answer: The correct answer for the blank is-

B) cytoplasm.

Cytoplasm is the fluid filled compartment ( a thick, gel like substance) within the cell of a living organism that is mainly composed of water, salts, and proteins. It is surrounded by the cell membrane ( plasma membrane) and contains all the parts of cell ( such as in eukaryotic cell, it contains all the cell organelles except nucleus). It is the site for all the essential cellular processes.

Thus, option B) is the right answer.

Answer:

Option C= A hydrogen bond formed between a polar side chain and a hydrophobic side chain.

Explanation:

All three given options a, b and d have common mechanism to accommodate the polar amino acid.

A= A hydrogen bond forms between two polar side chains.

B= A hydrogen bond from between a polar side chain and protein back bone.

D =  hydrogen bond form between polar side chains and a buried water molecules.

All these are use to accommodate the polar amino acid.

While option C is not used. which is:

The latent heat of melting is 80 calories for 1 gram of ice. if 1 gram of ice absorbs 60 calories what do i get?
Eva8 [605]
Latent heat of melting is the energy that a solid absorbs to change its phase as its liquid. During this process, since all energy is used to change the phase, the temperature is constant.

Here the latent energy of melting for 1 g of ice is 80 calories and that 1 g of ice only absorbed 60 calories. hence the phase is not changed because it requires more 20 calories to melt.

Hence 1 g of ice remains as its solid phase (ice).
