It maintains cell shape and assists movement of the cell parts and it also provides stability of the shape.
Answer:
(E) left atrium.
Explanation:
Pulmonary veins are veins that carry oxygenated blood from the lungs to the heart (left atrium). These veins are part of the pulmonary circuit:
Venae cavae are a vessels (vena cava interior and superior) that carry deoxygenated blood from the body to the right atrium. From the right atrium through the tricuspid valve the blood goes into the right ventricle. Then, from the right ventricle through the pulmonary valve the blood goes into the main pulmonary artery which carries deoxygenated blood to the lungs (to recieve oxygen). Oxygenated blood from the lungs travels to the heart: two pulmonary veins from each lung to the left atrium.
Answer:
Question: If is possible to synthesize proteins in vitro (in a test tube) without the use of living cells. If starting from a mature mRNA transcript, which of the following components would not be needed to do this?
(a) Adenine Molecules
(b) Amino Acids
(c) tRNAs
(d) Ribosomes
The correct answer is (a) Adenine Molecules.
Explanation:
Transcription can be explain as transfer of genetic information from DNA to RNA. During transcription, mRNA is produced as copy of gene to allow the genetic information go out of nucleus to form protein. Adenine molecules would not be needed for this process. Actually, It is formed when adenine is attached to a ribose ring and one of the bases used in forming nucleotides of the DNA and RNA not in transcription.
Answer:
Is it lymp or lymph..?
I know about lymph
Lymph is the fluid that flows through the lymphatic system, a system composed of lymph vessels and intervening lymph nodes whose function, like the venous system, is to return fluid from the tissues to the central circulation.
Two functions of lymph are:
•The removal of excess fluids from body tissues. ...
•Absorption of fatty acids and subsequent transport of fat, chyle, to the circulatory system.

When a cyclic AMP is dissolved in water it loses its bond between its P atom and its main aromatic ring. In the pictures attached, is shown in red the bond that's lost. The cyclic AMP is a messenger involved in many biological processes.
