Answer:

Glycolysis

Explanation:

Glycolysis is the first step in cellular respiration, both aerobic and anaerobic.

Glycolysis occurs in the cytoplasm, whereas other steps of aerobic respiration occur in the mitochondria.

During glycolysis, a six carbon glucose molecule is broken down into two three carbon molecules of pyruvic acid. This process yields two molecules of ATP. Two hydrogen ions and two molecules of water are also released during the process.

Which process is a squeezing motion of the circular layer of smooth muscle in the small intestine?
Over [174]

Segmentation is a squeezing motion of the circular layer of smooth muscle in the small intestine.

<h3>What is segmentation in the small intestine?</h3>

Segmentation, which mostly affects the small intestine, is made up of localized contractions of the Gastro-Intestinal tract's circular muscle. These contractions separate out little portions of the intestine, allowing their contents to move back and forth while being continuously divided, broken up, and mixed.

Our intestines' circular muscles contract during segmentation to churn food back and forth, rather like a washing machine. This churning helps break down food into tiny bits for digestion by allowing it to mix with gastric secretions in the intestines. By bringing chyme into contact with the intestinal walls during segmentation, the technique also helps to increase absorption.

A cell that consists of a 65% salt concentration is placed in a solution with a 27% salt concentration. What will happen to this
zzz [600]

Answer:

The correct answer would be - the cell will get water and expand.

Explanation:

If a cell with a higher salt concentration is placed ins a low salt concentration solution then the water will move through the cell membrane into the cell and the cell will swell or expand.

Water always moves from a low solute concentration to a high concentration area, therefore, if the cell has more salt concentration than outside the cell water move inside the cell which leads to an increase in the water concentration inside the cell and expands its size.
