The head of a phospholipid is "water loving" and is said to be hydrophilic.
Answer:
2n=46(duplicated)
Explanation:
Prior to cell division, which can either be meiotic or mitotic, the DNA content of the cell gets doubled in the Synthesis phase of the Interphase stage. In humans like myself, our cells consist of 23 pairs of chromosomes or 46 chromosomes. The DNA doubles in order for each daughter cell to get the correct number of genetic material.
After the S-phase, the chromosome number in the human cell does not change, just that each individual chromosome gets replicated or duplicated to form sister chromatids. Therefore, the human cell will contain 46 duplicated chromosomes or 92 sister chromatids after Synthesis phase and before the meiotic division.
Note that, humans are diploid organisms (2n) i.e. two set of chromosomes. Hence, they undergo meiosis to reduce their ploidy level from diploid (2n=46) to haploid (n=23).
A) is correct
because the experiment is based on radiations, not the type of radiations so it can't be b.
it can't be c because again, it's talking about the radiation
it can't be d because the water isn't an effect of radiations
