Explanation:

Where does gas exchange take place in the respiratory system, and between what structures?

Answers

The gas exchange take place in the lungs where carbon dioxide and oxygen diffuse across alveoli (which are attached to every bronchial tubes) and tiny capillaries surrounding them.

Final answer:

Gas exchange in the respiratory system occurs in the alveoli, which are small air sacs located in the lungs. Oxygen diffuses from the alveoli to the capillaries, while carbon dioxide diffuses from the capillaries to the alveoli.

Explanation:

Gas exchange in the respiratory system takes place in the alveoli, which are small air sacs located at the ends of the respiratory bronchioles. These structures are found within the lungs. The alveoli are surrounded by capillaries, which are tiny blood vessels.

When we breathe in, oxygen from the air enters the alveoli and diffuses across the thin walls of the alveoli and capillaries. At the same time, carbon dioxide, a waste product, diffuses from the capillaries into the alveoli to be removed when we exhale.

So, the gas exchange occurs between the alveoli and the capillaries surrounding them.

Many organs are involved in the processes of keeping the blood and the body clean. When poisonous or harmful substances are in the blood, they are absorbed by the _______ and released in a less harmful form. When wastes are present in the blood, they are filtered out and removed from the body by the _______.

Answers

The answer is; Liver, kidney

The liver is a significant organ of detoxification of the body. The xenobiotic biotransforming enzymes in the liver breakdown and oxidize/ reduce and hydrolyze toxins and make them less effective. The specificity of these enzymes is broad thence are able to break down a wide variety of toxins we are normally exposed to in our environment.

When the liver break down the toxin to less harmful metabolites, these molecules are filtered out by the kidney and excreted outside the body with urine.

what causes a protein to migrate on SDS-PAGE in such a way that it appears to be a protein that is much bigger

Answers

SDS-PAGE is used for separation of proteins or protein fragments based on their size. SDS is an ionic detergent that denatures and binds to proteins. Consequently, the proteins are negatively charged. An electric current is running through the gel in the electrophoresis with positive pole on the bottom. Since proteins are negatively charged, they migrate toward the positive pole of the gel. Some of the proteins are smaller so they can travel more quickly through the gel than the bigger proteins. 

Drosophila eye color is an X-linked trait. Red eye color is dominant, and white eye color is recessive. Which Punnett square shows the probability that 25 percent of offspring will be red-eyed males?

Answers

A punnet square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. The diagram is used by biologist to determine the probability of an offspring having particular genotype. Base on that the possible answer would be that the two parents should have genotype a of something like XXi x XY where Xi is the allele for red eye colour

The probability depends on the nature of the genotypes of the parents.

What is a Punnet square?

The term punnet square has to do with a instrument that is used to determine the probability of the phenotype of an offspring. This probability depends on the nature of the genotypes of the parents.

In this case, the question is incomplete, the probability depends on the nature of the genotypes of the parents,
