Biology

Shtirlitz [24]3 years ago

Answer:

Mitosis is a division of a eukaryotic cell in which the chromosomes are evenly distributed among the daughter cells.  

In multicellular organisms, both sexual and asexual reproduction is followed by cell division, which ensures the growth and development of the organism. In addition, cell division is necessary to replace dead cells and repair injuries. New cells are constantly being added and old ones are being destroyed. About a hundred thousand more cells are created every second, and of course the same number dies. The new cells start with the division of the source cell. The cells formed in this way are called daughter cells. Stem cells can gradually divide into all the different cells in the body through mitosis.

Most of the body's cells are constantly renewed by mitosis, but there are also so-called irreplaceable cells that are formed only once in a lifetime for the life of the organism and do not regenerate by mitosis.

If the xylem in a young tree is damaged, which process is first affected?
scoray [572]

Roots transporting water

BigorU [14]

Answer:

The correct option is <em>B. 25 %</em>

Explanation:

 A heterozygous type can be described as the type in which both the alleles of a gene are different. If both the alleles of a gene are similar in an organism, then the person is said to be homozygous for the trait.

In the above question, two heterozygous parents are to be cross- bred to check the probability of them producing homozygous alleles (AA).

A punnet square made will show the following results:

       A     O

A     AA    AO

B    BA     BO

Hence, there will be 25% chance that the offspring produced could be homozygous AA.
