<u>Answer:</u>
<u>Haploid cells join to form an organism that has a complete set of chromosomes is the correct answer.</u>
<u></u>
<u>Explanation:</u>
<u>In the fertilization process two haploid cells sperm fuse with an egg which results in the formation of a diploid cell.</u>
<u></u>
<u>meiosis produces haploid cells rather than diploid cells because in Meiosis the chromosome number gets reduced.</u>
<u></u>
<u>In the Meiosis process the number of chromosomes in the daughter cells gets reduced to half than of the parent cell and this process results in the formation of four haploid daughter cells</u>
<u></u>
<u>So Haploid cells join to form an organism that has a complete set of chromosomes is the correct answer.</u>

R-strategist. The organism produces many offspring very quickly.
Answer:
A) One band of intermediate density and one band of heavy density.
Explanation:
According to semi conservative model of replication the two DNA strands separate during replication such that the new DNA molecule has one parental strand and one new strand. In this experiment, originally E.Coli cells were grown in 14N medium so all the DNA strands had 14N. When the medium was changed to 15N, only 15N would be available to the cells for replication.
After first round of replication all DNA molecules would be of intermediate density as one strand would be old 14N strand and another would be new 15N strand. After second round of replication 15N strand would be formed from both 14N strand and 15N strand. So, one band will be formed of intermediate density (14N-15N) and another would be of heavier density (15N-15N).
Answer:
Vitamin D3 is synthesized in keratinocytes of the two epidarmal layers namely <u>stratum basale </u>(bottom layer) and <u>stratum spinosum</u>.
Explanation:
In the two epidermal layers of the skin namely <u>stratum basale</u> and <u>stratum spinosum</u>, 7-dehydrocholesterol (pro-vitamin D3) is converted to vitamin D3. This process takes place in the presence of ultravoilet radiations. Briefly, upon exposure, the pro-vitamin D3 is photolyzed to pre-vitamin D3. The pre-vitamin D3 then isomerized to form vitamin D3.
