Differentiate the pH conditions of the stomach and intestine and how does it help in the digestion of food.

babunello [35]

Answer:

pH of stomach is more acidic ranging from 1.5 to 3.5 meanwhile intestine is more on the neutral side ranging from 6 to 7.4

Explanation:

as far as it is concerned about digestion relation between the two stomach and intestine is that stomach has more acidic pH because most of the the digestion occurs in stomach. the more acidic ,the more quickly food will be broken down to essentials .like an upset stomach as it overdoes the digestion as for the intestine it is mainly responsible for absorption of already digested food..

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: $\frac{1}{16}$

after being bit by a poisonous snake, jacob was treated with an injection of an antiserum produced by immunizing a horse or shee

brilliants [131]

T cells and B cells are the two main cell types that are crucial to the efforts of the adaptive immune response, in addition to cytokines and APCs.

<h3>Passive immunity is conferred by which of the following?</h3>

By supplying antibodies or lymphocytes that have already been produced by an animal or human donor, a vaccination may also impart passive protection. Most vaccines are administered parenterally (by injection), although some can also be taken orally or even nasally (in the case of flu vaccine).

Monoclonal antibodies search for and bind to the spike protein that protrudes from the coronavirus that causes COVID-19 after they have entered your body. Monoclonal antibodies that bind to the spike protein can prevent the virus from entering cells, slowing the infection.

The endothelial cell glycocalyx, which serves as a molecular sieve, and pressure gradients in the capillary beds both affect how lymph fluid is formed. toward with fluid propulsion
