Options for the question have not been provided. They are as follows:
(1) DNA in muscle cells
(2) base sequences in liver cells
(3) genes in an egg cell
(4) number of chromosomes in a fetal bone cell
Answer:
(3) genes in an egg cell
Explanation:
Evolution is the change in characteristics of a species which it develops over the time. These changes can be a result of natural selection, genetic drift, founder effect etc. They are passed from one generation to another hence the alleles for them get fixed in the population.
For evolution to occur, change should take place in germ cells. Germ cells are the one which fuse to form the organisms of next generation. If there is a change in their genes, it would also appear in next generation, unlike changes in genes of somatic cells. Since egg cell is a germ cell it is the correct answer.
I think the answer to this would be A
Embryonic stem cells have the potential to produce regenerated tissues, such as skin. They could provide means of healing diseases such as type 1 diabetes where a particular cell has been lost or is malfunctioning.
<span>d. During mitosis daughter cells receive an exact copy of the parent cells and during meiosis it only receives half of the genetic material.
</span><span>Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. Meiosis on the other hand is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells. </span>
<span>a).only leaves will show color flower will tend to be dark.
b).only flower will show up leaves will tend to be dark.
c). both leaves and flowers will be dark.
(any object which has a color absorbs rest of colors of spectrum except that color which it reflects
for example: green leaves absorbed v.i.b.y.o.r. except green which is reflected by leaves)
so if placed in red light they will not show any color because leaves will absorb red color)</span>
