<em>The traits of multicellular organisms are A. Can reproduce a whole colony in a matter of hours. and D. Divide in two to produce.</em>
Answer:
The correct answer is D increasing the activity of protons pumps that lowers the pH of the cell walls allowing cells to elongate.
Explanation:
The plant growth hormone auxin work by increasing the H+ ion concentration thus decreasing the pH of the apoplast.
The decrease in the pH of the apoplast helps in the cell wall extension that ultimately result in cell growth.
Auxin hormone exert this effect by increasing the activity of increasing the activity of proton pumps in the apoplastic membrane.
Answer:
heterologous
Explanation:
Recombination occurs between homologous regions between chromosomes.
Although sex chromosomes come from autosomal chromosomes and were once homologous, they have evolved distinctly casuing low homology between them. Currently sex chromosomes are heterologous and differ substantially in composition. In fact, recombination between sex chromosomes only occurs in a small pseudoautosomal region that is still homologous.
Cellulose is a form of carbohydrate.
Answer:
Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles. This recombination process creates genetic diversity at the level of genes that reflects differences in the DNA sequences of different organisms.
