<u>Answer:</u>
Although statements are not given in the question, we could make the most possible deduction as follows:
The allele for purple flowers is dominant whereas allele for white flowers is recessive.
<u>Explanation:</u>
According to the question,
- Purple flower plant was crossed with white flower plant.
- All offsprings have purple flowers.
Here we have one possibility that both parents were homozygous but in their own traits. <u>Purple flower</u> plants were "PP" and white <u>flower plants</u> were "pp" So, the <u>first progeny</u> (direct offsprings) would have "Pp". So, as per considerations, purple is dominant allele which will mask the recessive allele thus defining the color of all offsprings as purple. However, further cross of their generation will definitely end up into purple and white flowers (3:1) but this condition is not mentioned in the statement.
It's a decomposition reaction. It's a chemical reaction because one substance (H2O2) is breaking down and becoming 2 completely new substances (H2O and O2)
well, there are a few meanings...
1. the area of variation between upper and lower limits on a particular scale.
2. a set of different things of the same general type.
<span>The major difference between viruses and living cells is that viruses do not have nuclei while living cells do. A second major difference is that viruses need a host cell to survive while living cells do not. For the most part, viruses just contain genetic material (typically in the form of RNA) inside of a capsid. Living cells have many more organelles, including ribosomes and cytoplasm, which viruses lack.</span>
The function of the nucleolus is: D. Assembly of ribosomes.
The function of the nucleolus is to transcribe DNA into ribosomal RNA and assemble RNA into ribosomal subunits. The creation of RNA is important because RNA makes up ribosomes which are responsible for protein synthesis in the cell.
