Which two organ systems regulate homeostasis in our bodies?

Usimov [2.4K]

The correct answer for the given question above would be option A. The two organ systems that regulate homeostasis in our bodies are nervous and endocrine. The nervous system is responsible in the coordination of different systems in the body, including the voluntary and involuntary function. Whereas, the endocrine system, along with the nervous system is responsible for the regulation of different hormones that are responsible for different functions in the body.

In tomato plants, the allele for purple stems is dominant to allele for green stems and the allele for red fruit is dominant to

Kamila [148]

So let's call the allele that is dominant for purple stems is P, and the recessive allele yielding green stems is p. And let's say that the allele that is dominant for red fruit is R and the recessive allele for yellow fruit is r.

The two plants are each heterozygour for both traits, meaning that the cross is going to be:

PpRr x PpRr

So let's setup a Punnet Square:

$\left[\begin{array}{ccccc}&PR&Pr&pR&pr&PR&PPRR&PPRr&PpRR\4&PpRr&Pr&PPRr&PPrr&PpRr&Pprr\\pR&PpRR&PpRr&ppRR&ppRr&pr&PpRr&Pprr&ppRr&pprr\end{array}\right]$

The genotypic ratios (alleles) and phenotypic ratios are as follows:

PPRR (Purple stem, Red fruit): $\frac{1}{16}$

PpRR (Purple stem, Red fruit): $\frac{2}{16}$ or $\frac{1}{8}$

ppRR (Green Stem, Red fruit): $\frac{1}{16}$

PPRr (Purple stem, Red fruit): $\frac{2}{16}$ or $\frac{1}{8}$

PPrr (Purple stem, Yellow fruit): $\frac{1}{16}$

PpRr (Purple stem, Red fruit): $\frac{4}{16}$ or $\frac{1}{4}$

pprr (Green stem, Yellow fruit): $\frac{1}{16}$

ppRr (Green stem, Red fruit): $\frac{2}{16}$ or $\frac{1}{8}$

Pprr (Purple stem, Yellow fruit): $\frac{2}{16}$ or $\frac{1}{8}$

So then we take the like phenotypic ratios and add them together:

Purple stem, Red fruit: $\frac{1}{16} +\frac{2}{16} +\frac{2}{16} +\frac{4}{16}=\frac{9}{16}$

Green stem, Red fruit: $\frac{1}{16}+ \frac{2}{16} =\frac{3}{16}$

Purple stem, Yellow fruit: $\frac{1}{16}+ \frac{2}{16} =\frac{3}{16}$

Green stem, Yellow fruit: $\frac{1}{16}$

Explain what would happen if the leaf tissue is kept at high temperature during the process of cell isolation

Aleksandr-060686 [28]

Answer:

Wilting of leaves occur.

Explanation:

if the leaf tissue is kept at high temperature during the process of cell isolation the leaf will shrink because of loss of all water. Due to high, temperature the stomata will be open and water is removed in order to remove heat from the body. A time comes that all water that is present in the cell will be removed and as a result wilting of leaves occur.
