Answer:

<em>The correct option is C) Water is repelled by the hydrophobic tails of the phospholipid.</em>

Explanation:

The cell membrane is made up of phospholipids. The phosphates make up the head and are hydrophilic. The lipids make up the tail and re hydrophobic. The cell membrane is double layered with the heads pointing outwards and the tails embedded inwards. As lipids do not dissolve in water, hence the cell membrane is partially permeable for water. The tails made up of lipids are hydrophobic and hence repel water.

Scientists routinely explore whether two different animal species have evolved from a recent common ancestor.Comparisons of items eaten for food is the LEAST useful technique to help with this determination

<h3><u>Explanation:</u></h3>

The features that are related to the anatomy of two organisms when they share them in common indicates that they are evolved from the common ancestor. When there exists a common feature between any two species physically then it is inherited form the common ancestor.

The two species having common traits involves similar genetic material called DNA, genetic codes that are similar and same translation and transcription process. Thus studying about genes and gene expression will be helpful to explore whether two different animal species have evolved from a recent common ancestor than including the studies related to Comparisons of items eaten for food.

Inga [223]

Take for example the group of prokaryotes against eukaryotes. They may be similar in a way that they contain cells with organelles such as mitochondria, ribosomes, cytoplasm, and many more. But they may differ in the presence of a cell membrane and a nucleus. Eukaryotes have cell walls and a nucleus, while prokaryotes don't have.

Is necessary for the absorption of vitamin B12 in the small intestine. Chief cells, Located primarily in the basal areas of gastric glands are chief cells, which secrete pepsinogen, the inactive proenzyme form of pepsin.

<h3>Which vitamin requires intrinsic factor which is secreted by the stomach in order to be absorbed?</h3>

Intrinsic factor is a protein that aids intestines absorb vitamin B12. It is created by cells in the stomach lining.

Thus, Chief cells,Located primarily in the basal areas of gastric glands are chief cells, which perspire pepsinogen, the inactive proenzyme form of pepsin.
