Answer:I really need it
Explanation:what’s the answer
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.

<u>Answer</u>:
Organic molecules present in chicken are Nucleic acid, proteins, carbohydrate and lipids
.
<u>Explanation</u>:
Chicken itself has the all four organic molecules in it. Organic molecules are those having carbon in it. They are attached by covalent bonds, in which electrons are being shared within the atoms. The nucleic acids are DNA and RNA which helps in the making of the proteins which are found in the various structure and ought to perform various metabolic functions. Proteins are the building block of the amino acids. Lipids found are the fat bodies, burning of lipids gives us energy.
Answer:
Explanation:
The correct answer is (B) Helicase creates the replication fork; single-strand binding proteins keep the single strands from reuniting. The replication fork is established by the enzyme DNA helicase, which separates the two complementary strands of a DNA molecule
Answer:
The correct option is : It undergoes a lysogenic cycle.
Explanation:
A virus can replicate inside a host cell by two process :
In the lytic cycle, the viral DNA makes copies of itself and manufactures the viral machinery inside the host cell. Eventually, the host cell bursts causing the release of the viruses. In such a condition the varicella virus would cause chicken pox.
In the lysogenic cycle, the DNA of a virus get incorporated into the DNA of the host. The viral DNA might replicate when conditions become favourable and cause diseases. In such a condition, the varicella virus would cause shingles.
