Answer:
A phospholipid
a. has both polar and nonpolar regions.
Explanation:
Phospholipids, as amphipathic molecules, consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged hydrophilic (water-loving) polar head, which face outward and are attracted to the intracellular and extracellular fluid. The fatty acids are the uncharged, hydrophobic (water-fearing) nonpolar tails, which face the inside, away from the water and meet in the inner region of the membrane.
Answer:
preparedness.
Preparedness is the tendency to learn some associations more easily, quickly and permanently than others.
If they remain isolated for a long period of time, the two groups will probably diverge genetically, and may result in speciation.
Genetic divergence is the process whereby two groups of the same ancestral species acquire autonomous genetic changes through time, usually after the groups have been separated reproductively for some period of time.
Speciation is an evolutionary process whereby populations develop to become different species.
The answer is alleles detached from one another during
anaphase of meiosis I, when the homologous pairs of chromosomes separate. During
anaphase I, homologous pairs are drawn apart, and
they go in the direction of the opposites of the cell. Meiosis I finishes
with the manufacture of two haploid daughter cells for the reason that
the homologous pairs of chromosomes have been separated.
Greater light intensity would mean a faster rate of photosynthesis in plants. photosynthesis takes in carbon dioxide and water to produce glucose and oxygen. therefore, a greater light intensity would mean faster oxygen production
