Robber crabs have more in common with humans, which are vertebrates. Sponges are simple organisms that don’t have tissues. Crabs and humans have specialized cells and tissues, bilateral symmetry, and a coelom. According to the phylogenetic tree, vertebrates and arthropods have more nodes, or common ancestors, than crabs have with sponges.

NemiM [27]

Entropy, is mainly responsible for the resting state of this protein.

Hydrogen bonds, disulfide bonds, and dipole-dipole interactions produce the complicated folding styles seen in secondary and tertiary structure. however, if a protein does not have these elements of structure, it'll undertake a kingdom in which its entropy is maximized.

Secondary shape is determined through hydrogen bonding within the amino acid chain backbone. Tertiary structure is the entire protein's form, decided Entropy Interplay and hydrophobic forces. The tertiary shape of a protein is the 3 dimensional shape of the protein. Disulfide bonds, hydrogen bonds, ionic bonds, and hydrophobic interactions all affect the form a protein takes.

The nonpolar amino acids have formed the nonpolar center of the protein, weak van der Waals forces stabilize the protein. furthermore, hydrogen bonds and ionic interactions between the polar, charged amino acids make a contribution to the tertiary structure.

Disclaimer: your question is incomplete, please see below for complete question

A. Entropy

B. Hydrogen bonds between amino acid residues

C. Dipole-dipole interactions

D. None of the above

Aquaporins would be expected to _____ in numbers when _____ is present in the blood
dangina [55]

Aquaporins would be expected to increase in numbers when there is an insufficient amount of water present in the blood.

Aquaporins are a type of proteins which are present in the integral membrane of the cells. They act as channels and help in the transport of water and small solutes across the membrane.

Whenever there is insufficient amount of water present in the blood, the antidiuretic hormone or the ADH responds. The aquaporins increase in number in the blood. They allow the transcellular reabsorption of water. Due to this fact, more water is able to escape from the collecting tubules and enter the blood.
