What happens when the lungs recoil? A. Expiration occurs.
B. Internal respiration occurs.
C. Ribs and diaphragm muscles contract.
D. Inspiration occurs.

Answers

Answer 1
Answer:

Answer:

The correct answer is option A.

Explanation:

Breathing is the exchange of air through the involved passages in between the atmosphere and the lungs. Inspiration is a process where we take air into the lungs from the atmosphere also known as inhalation.

Expiration is releasing air out of the lungs to the atmosphere. In expiration, the diaphragm relaxation and elastic recoil of tissue decrease the thoracic volume of lungs. That results in an increase the intraalveolar pressure in the lungs.

Thus, the correct answer is option A.

Answer 2
Answer: Expiration occurs when the lungs recoil.

"Ribosomes are described as the site of protein synthesis. Ribosomes consist of RNA and protein combined into a very particular shape. As a ribosome moves along an mRNA transcript, amino acids are joined together by peptide bonds. The formation of peptide bonds is facilitated by rRNA in the ribosome. Thus, rRNA can be described as a(n)"

Answer:

Catalyst

Explanation:

Translation is the second process of gene expression which occurs in the ribosomes of living cells. The ribosome is a complex of Ribosomal RNA (rRNA) and proteins. Translation occurs when ribosomes attach to the transcribed mRNA molecule to read its codons using the transfer RNA (tRNA's) anticodon. The tRNA then carries amino acid that corresponds the codon it reads to the growing polypeptide chain.

In this process, amino acids are attached to one another forming a peptide bond. This linking of one amino acid to another is facilitated by rRNA's as it helps catalyzes the reaction like an enzyme. Ribosomal RNA catalyzes the reaction that forms a peptide bond between the amino acid in the A site of the ribosome and the growing polypeptide (future protein) in the P site.

Which of the following is an example of a nonpoint source of freshwater pollution?A.) pesticide runoff from farm fields
B.) leaking toxic waste landfill
C.) sewage treatment plant
D.) factory waste piped into a stream

Answers

A.) pesticide runoff from farm fields

Freshwater pollution can be defined as the contamination of inland water with substances that affect its natural use and it can be caused by chemicals, petroleum, fecal waste, sediments and fertilization. Thus, non-point pollution is the process where pollution result from many diffuse sources such as agricultural areas which drain into the wind-borne debris or rivers.
