Answer:

Explanation:

Bacteria become 'factories' that produce a large number of copies of the recombinant DNA. There are several reasons for the use of bacteria as the host in the recombinant DNA technology. They are; Bacterial cells are easy to grow, maintain, and manipulate in a laboratory.

const2013 [10]

Answer:

The group needs to find signs of apical dominance, growth in response to light, vascular tissue differentiation, formation of lateral and adventitious roots, etc.

Explanation:

Lanolin is a solvent used to study physiological processes in plants by diluting hormone growth regulators (in this case, indole acetic acid). Indole acetic acid (IAA) is the most important auxin hormone in plants. Auxins are essential plant hormones synthesized in expanding shoot tips that move down the stem to the roots. These hormones coordinate cell division, elongation and identity during plant body development. IAA hormone is well known to regulate different plant developmental processes including, among others, apical dominance (where the central stem grows more strongly than other lateral stems), tissue differentiation, stem elongation, phototropism (growth in response to light) and gravitropism (response to gravity). For instance, under the application of IAA, it is expected that bean stems grow to imitate the response to light (phototropism) by bending away from the side where lanolin was applied.

Shortly after the zygote is formed, it begins the processes of duplication and division. Each resulting new cell has:
seropon [69]

Answer:A. the same number of chromosomes as was contained in the zygote.

Explanation:a zygote is formed when the sperm fertilize the egg .

After fertilization,the zygote undergoes cleavage.cleavage is the mitotic Division of the cells of a zygote to produce daughter cells.

These daughter cells are called blastomere,which contains the same number of chromosomes as the parent cells.the cells formed do not grow in size but continues to divide, forming a mass of cells.

This mass may be solid at first but as cleavage continues,the cells move away from the center,leaving a fluid filled cavity in the middle (blastocoel).

The mass of cells are called blastula.
