Answer;

D) glucose → lactic acid + energy

Explanation;

Fermentation refers to the process in which energy in form of ATP is generated in the absence of oxygen, through glycolysis alone.

Thus, Lactic acid fermentation is a type of anaerobic respiration that takes place in the muscle cells in which glucose is broken down to yield fast energy and lactic acid as a byproduct.

This type of anaerobic respiration converts pyruvate, final product of glycolysis, to lactic acid with regenaration of NAD+, which allows a continued production of ATP by glycolysis. Therefore, the muscles continues to produce energy when oxygen levels are low.

Answer:

(D). glucose → lactic acid + energy

Explanation:

Lactic acid fermentation can be defined as a metabolic process, which involves conversion of glucose into energy and lactic acid molecules.

It takes place in anaerobic conditions and takes place in some anaerobic bacterial cells and yeast cells. Animal cells, such as muscle cells also perform lactic acid fermentation under hypoxic conditions.

Thus, the correct answer is option (D).

In Drosophila, the bar mutant is characterized by eyes that are restricted to a narrow, vertical bar. When a bar female is mated

Lelechka [254]

Answer:

See the answer below

Explanation:

a) The mode of inheritance of the bar mutant is X-linked and dominant.

Assuming that barness is represented by the allele B.

Bar female = $X^BX^B$ or $X^BX^b$

Wild type male = $X^bY$

Bar female x wild type male:

$X^BX^B$ x $X^bY$

$X^BX^b$ $X^BY$ $X^BX^b$ $X^BY$

All of the F1 flies are bar because a single B allele is required for the trait to be expressed.

Bar male x wildtype female

$X^BY$ x $X^bX^b$

$X^BX^b$ $X^BX^b$ $X^bY$ $X^bY$

All the female offspring are barred while all the males are wildtype barred resulting in a 50/50 (857/905 is approximately 50/50) ratio of barred/wildtype offspring.

b) Genotypes of each of the cross above, including the parents and the F1 generations.

1. $X^BX^B$ x $X^bY$

$X^BX^b$ $X^BY$ $X^BX^b$ $X^BY$

2. $X^BY$ x $X^bX^b$

$X^BX^b$ $X^BX^b$ $X^bY$ $X^bY$

What process occurs at the boundary between the capillaries and the alveoli?

mr_godi [17]

Answer:

Diffusion.

Explanation:

Oxygen in the lungs diffuses from the alveoli into your bloodstream through capillaries and carbon dioxide diffuses from the bloodstream into the lungs also through these capillaries. The carbon dioxide is then breathed out.

Hope this helps! :)
