Answer:
When a future offspring has just been conceived it has the highest level of potency in Totipotency.
Explanation:
Potency is the ability of cells to differentiate. AT different stages of development the level of potency changes. The highest level of potency is Totipotency and these cells have the ability to develop a whole organism. The common examples are spores and zygote. In embryonic stage the cells are Pluripotent and they can differentiate into different type of cells. Pluripotent cells after further development changes into Multipotent cells. Unipotent cells have the least potency and can develop only in one cell linage.
Answer:
<em>UV rays are highly injurious to living organisms since </em><em>DNA</em><em> </em><em>and</em><em> </em><em>proteins</em><em> </em><em>of</em><em> </em><em>living</em><em> </em><em>organisms</em><em> </em><em>preferentially</em><em> </em><em>absorb</em><em> </em><em>U.V</em><em> </em><em>rays</em><em> </em><em>and</em><em> </em><em>it's high</em><em> </em><em>energy</em><em> </em><em>breaks</em><em> </em><em>chemical</em><em> </em><em>bonds</em><em>. UV rays damage DNA and mutation may occur. It causes ageing of the skin, damage to skin cells and various types of skin cancers.</em>

Answer:
33
Explanation:
Gametes (sperm or egg) have half the chromosome of a diploid cell. That's why they are haploid cells.
If chromosomes come from a cell with 66 chromosomes, sperm will have 66/2 = 33.
That's why us humans have 46 chromosomes, but our egg or sperm has only 46/2 = 23 chromosomes.
