The class of macromolecule a steroid belongs to is a lipid.
Answer:
The process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin, and it is now regarded as be the main process that brings about evolution.
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
Answer: A branched polymer has greater terminal glucose residues in comparison to a unbranched polymer of the same molecular weight resulting in a higher number of terminal glucose residues required to be mobilized when energy is demanded. Enzyme and polymer evolve together to meet the dire need for rapid mobilization.
Explanation:
In comparison to an unbranched polymer, a branched polymer has a more compact and symmetrical molecular conformation with a greater terminal glucose residue. It can be broken down easily when energy is needed. For instance, the branched form of starch, amylopetin, in the small intestine starch is hydrolyzed to form glucose which is converted to biochemical energy and stored for later use.
4, any other option is a mix between dna and rna, or describes rna
Basically you have hydrophilic (water loving) and hydrophobic (water hating) the heads are hydrophilic and the tails are hydrophobic. this allows the cell to be selectively permeable. this means selectively allows or does not allow substances In or out
