Fat; they store twice as much energy per gram
Answer:
The correct answer is ''high survival rates of offspring and the cost of parental care''
Explanation:
Natural selection is the differential reproduction of some genetic variants with respect to others. Natural selection favors individuals who maximize their total reproductive success throughout life, that is, it favors certain phenotypes or variants are associated with greater offspring and / or greater survival, that also means that selection will favor those who stop spending on a particular breed at the right time to invest in another, that is, the amount of energy invested in each of them. This same natural selection also favors those genes that make it effective when the body that carries them is in development to extract all possible parental investment from their parents.

Explanation:
Answer:
The correct answer is "the S layer may play a role in protecting cells from viruses and predatory bacteria found in nature but not in laboratory cultures".
Explanation:
The S-layer (surface layer) is a part of the cell's envelope comprised of of identical proteins or glycoproteins that could be found in archaes and some bacterias in nature. The function of the S-layer is unknown, however the fact that is only seen in nature suggest that it may play a role in protecting cells from viruses and predatory bacteria found in nature but not in laboratory cultures. It is likely that archaes and bacteria synthesize the S-layer when they recognize viruses and predatory bacteria in nature, the S-layer is not synthesized in laboratory cultures because these pathogens are not present.
Answer:
No, there are no differences
Explanation:
Deoxyribonucleic acid (DNA) is a molecule composed of two polynucleotide chains that interact together in order to form a double helix. This molecule (DNA) carries the genetic instructions that make each species unique. In DNA, each polynucleotide chain is composed of nucleotide monomers: a nucleotide is composed of a deoxyribose sugar attached to a phosphate group and one nitrogen-containing base (i.e., adenine, thymine, guanine and cytosine). This basic structure is the same among different species, and, therefore, genetic differences between different groups (in this case, animals, plants, and bacteria) are caused by differences in the nucleotide-base sequences of their DNA molecules.
