To prevent acid from seeping in the stomach, the stomach cells join one another via

The stomach and the cells that comprise it have a three-part protection system to protect from the acid contained in the stomach, comprised mostly of compact cell unions.

The stomach is one of the main digestive tract organs. Its job is to break down the food we ingest and pass it along to the rest of the digestive tract. To perform this action, the stomach secrets hydrochloric acid. However, the stomach itself is not damaged by this acid due to a three-part protective system comprised of:

Tight epithelial cell lining
Mucose Barrier
Bicarbonate secretion

The cells present in the epithelial lining of the stomach join one another via compact cell unions to form a closed barrier which is then covered by a thick Mucose barrier. This along with the secretion of bicarbonate which works to break up the acids present in the stomach and ingested, form a sealed barrier that protects the stomach from harm.

Answer:

Mutation

Explanation:

I believe it is a mutation. A mutation is when the DNA is copied with a small mistake. Ex: AGCC => AGGC

Then, after a mutation, the DNA isn’t exactly identical because of this mistake in the DNA after copied.

vlabodo [156]

Answer:

E2F transcription factors

Explanation:

The E2F transcription factors (TFs) encode intracellular factors associated with the control of the cell cycle. E2F are TFs that bind to promoter consensus sequences in order to activate transcription. These TFs control the expression of target genes involved in cell proliferation including, among others, genes for DNA replication and mitotic activation. Moreover, the E2F proteins also may act as a link between cell fate and the cell cycle. The retinoblastoma (Rb) is a protein that modulates the activity of the E2F family of TFs, and it has been shown that the Rb/E2F pathway is a key molecular mechanism associated with cell proliferation.

Why does water move along its concentration gradients?

Artemon [7]

There is an electrical gradient and there is a concentration gradient.

1.) Chemical gradient better known as concentration gradient is much more powerful and compelling than the electrical gradient.

2.) Water is a polar molecule, meaning one side it positively charged while the other is negatively charged. This polar charged molecule causes water to have a weaker electrical gradient, thus the water has to move on its concentration gradient.
