C Increased nitrogen levels in the ponds
Answer:
Answer of the question is explaine dbelow.
Explanation:
Rho GTPases interact with a variety of effectors to control actin cytoskeleton
reorganization, cell shape, and cell polarity. RhoA regulates cell shape and adhesion by
the assembly of contractile actin microfilaments into stress fibres. Rho GTPases also
regulate proliferation and cell-cycle progression, especially GuS transition.
All the cells are about to enter mitosis means they cross GuS transition, a drug that is a
potent inhibitor of RhoA activity has no affect on the cell because these cells already in
G2 phase. So, all the cells appear to be in telophase.
So, the correct choice is A. all the cells appear to be in telophase.
You have already worked out that the white flower must have genotype pp (two recessive white alleles) and that the purple flower could be homozygous (PP) or heterozygous (Pp).
<span>Now you need to draw Punnet squares for both possibilities and show that the way to determine the genotype is the proportion of purple offspring. If the genotype is PP, then all the progeny will inherit one P and one p, making 100% purple flowers. If the purple flower is Pp, then half will inherit P and half will inherit p, making for half white and half purple flowers in the next generation.</span>
The plants ploidy is decided based on the chromosome within the nucleus . Plant can be either heterozygous or homozygous.
The major distinction between homozygous and heterozygous individuals is that the former have two identical alleles while the latter have both dominant and recessive alleles. Over several generations, kids with the same characteristic are produced through self-breeding between homozygous individuals.
Heterozygous and homozygous chromosomes are seen in human beings. Allele pairings are categorized as Heterozygous and Homozygous. A heterozygous person possesses various alleles, whereas a homozygous person carries a pair of identical (RR or rr) alleles (Rr).
Let's take the gene for hair colour as an example. This gene has two alleles, one of which is responsible for black (r), and the other for black (R). On a homologous set of chromosomes, such as RR or rr, homozygous people will carry the same colour allele, but heterozygous people will carry distinct colour alleles.
Hence, depending on type allele can be homozygous or heterozygous.
