Answer:

See the explanation below.

Explanation:

Mitosis has to do with the division of somatic or vegetative cells. Diploid parent cells divide to give rise to two diploid daughter cells that are genetically identical to the parent cells. Mitotic process is important for for wound healing, growth and development of living organisms.

On the other hand, meiosis is concerned with the division of sex cells. Diploid parent cells divide t give rise to four haploid daughter cells that are genetically different from the parent cells as a result of crossing over and recombination. Meiotic process is important in sexually reproducing organisms. It ensures that the ploidy level of organisms are kept constant from one generation to the other.

In mitosis, the first stage is prophase. The nucleolus disappears and the two centrosomes begin to form the mitotic spindle. The spindle xtends between two opposite poles f the cell. Next is the metaphase. The centromeres of the chromatid pairs align at the center of the miotic spindle. Then anaphase, the centromeres will split that separates the chromatid pair. They are now called chromosomes. The last phase is the telophase. The chromosomes will then form a thread-like chromatin and for ache envelope, a nucleoli appears. The type of cell division that produces gametes with half the normal chromosome number is the meiosis. Meiosis is the type of cell division used in sexual reproduction. It will occur in the testes and ovaries.

Difference between paw paw and tomato

choli [55]

Answer:

❥ Ripe pawpaws give off a wonderful fruity aroma. If the pawpaw does change color, it will likely turn a lighter shade of green, possibly with some yellowing. A more reliable indicator is feeling. The fruit will begin to feel softer, much as a peach or avocado.

❥ Your ripe tomato will give slightly to the touch. It shouldn't be soft but rather a little tender. Because tomatoes ripen from the inside out, this is a good indicator that it's ready.

If scientists were trying to construct recombinant dna molecules, how would they do it?

Tamiku [17]

Constructing recombinant DNA or rDNA scientists should combine both DNA from two different species. Based on study, rDNA is possible if both DNA that should be combined should have the same chemical structure. Most o the DNA do have the same structure they only differ in nucleotide sequence.
