After the esophagus which comes next in the alimentary canal
mina [271]
The food bolus will then get digested in the stomach.

Specifically, only protein is chemically digested into short polypeptides under the enzyme pepsin. The gastric juice that contains pepsin is produced by the gastric glands. The stomach is very acidic. It has a pH value of around 2. This is because it has to make sure that only pepsin is functional and so as because hydrochloric acid is present. 

Polypeptides are not yet the final form of protein, amino acids are. But the process of breaking down polypeptides into amino acid is yet to be done at this stage, so as the other digestion of e.g. carbohydrates or fat. They'll mostly be done in the duodenum, which is the next stage after the stomach.

Why do you pass out if you lock your knees?
Inga [223]
It's caused by blood pooling in the legs, so there's insufficient return to the heart and brain. Normally, moving one's legs helps to pump blood back to the heart through muscle contraction. Locking the knees makes standing still easier, but reduces use of the leg muscles. In some people, this pooling may lead to hypoperfusion of the brain and fainting, which is essentially the body's way of putting the brain and the legs and the heart at the same level.

Which term best describes the change from more light-colored moths to more dark-colored moth:
maria [59]

Answer:

The correct option is B) adaptation

Explanation:

The features and properties of an organism that make it favourable to live in an environment are termed as the adaptations of that organism. Over time, evolution occurs and organisms with better adaptations survive as they are better suited to live in a particular environment. The light-coloured moths were adapted to live on Earth when the colour of the trees had not gone dark. With time, as the colour of trees got darker, the moth had to change colour to be better adapted to live on Earth.
