Regulation of opening and closing of stomata
Answer:
The correct answer would be:
- Genotype ratio: 1 (PP) : 2 (Pp) : 1 (pp)
- Phenotypic ratio: 3 (polka-dot tails) : solid colored tail
The genotype of both parents is Pp (heterozygous).
Thus, both the parent would produce two types of gametes which are P and p.
The cross would result in the production of offspring with three types of genotype PP, Pp, and pp in 1:2:1.
Offspring with PP and Pp will have a polka-dotted tail as it is the dominant trait.
Thus, the phenotype ratio would be 3 (polka-dotted tail) : 1 (solid colored tail).
Answer:
a. Determine the allele frequencies of:
f(T) = 0.485 ≅ 0.48
f(t) = 0.515 ≅ 0.52
b. Determine the genotype frequencies of the exposed generation
- F (TT) = 0.21
- F (Tt) = 0.55
- F (tt) = 0.24
the genotype frequencies of the next generation
- F(TT) = 0.23
- F(Tt) = 0.5
- F(tt) = 0.27

Due to technical problems, you will find the complete answer and explanation in the attached files
Homeostasis is the attempt to maintain stable conditions (particularly in an organism). It is done by using feedback loops (positive and negative).
Telomerase activity is controlled during development and is extremely low in somatic (body) cells, virtually undetectable. These somatic cells age because they do not frequently use telomerase.
- Telomeres are repetitive sections at the very ends of chromosomes that are present in a variety of eukaryotic species, including humans and unicellular protists.
- Each round of DNA replication wears down a little portion of the telomeres, which serve as caps to safeguard the interior chromosomal regions.
- Most somatic (body) cells do not typically have telomerase activity, but certain adult stem cells and germ cells—the cells that produce sperm and eggs—have.
- Adult germ cells, tumor cells, and fetal tissues all contain telomerase. Telomerase activity is controlled during development and is extremely low in somatic (body) cells, virtually undetectable. These somatic cells age because they do not frequently use telomerase.
