Answer:
HeLa cells contain rare traits that make them invaluable to scientific research. Research into the Lacks family may provide insight into this mutation and cell proliferation.
Explanation:
HeLa cells have a controversial origin, rooted in ethical breaches. They were derived from a non-consenting, female African-American donor patient, Henrietta Lacks who was terminally ill with a form of cervical cancer. These particular cells have a remarkably short period of proliferation, due to their active telomerase.
During cell division, these telomoerases were found to make repeat copies of the cell's telomere, and the cells can divide an unlimited number of times in lab cell cultures- a very rare occurrence. They were later commercialized- HeLa cells are durable, robust and commonly used in cancer cell research.
Answer:
Echinoderms have a calcium carbonate endoskeleton, and vertebrates have a bony endoskeleton made of calcium phosphate. have bones mostly made of calcium phosphate.
Explanation:therefore, echinoderms do not have true endoskeletons.
The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue. Some species of algae are capable of growing very quickly.
Proteasomes are a large protein complex present in all eukaryotic cells that break down protein.
<h3>What are proteasomes?</h3>
It is considered one of the main pathways involved in the processes of enzymatic protein degradation.
It is the group of proteins that are associated forming large complexes, whose function is to digest cytoplasmic proteins, generating peptides.
Therefore, we can conclude that proteasomes is a large protein complex present in all eukaryotic cells that breaks down protein .

Answer:
Explanation:
If you are having a question be sure to give options next time, just answered this question because it was there at khanacademy.org, if you want it with the options.... Well then, it's:-
Option 1: Because of his "Pact of Steel" with Hitler, he entered Italy into WWII with the Axis as soon as Britain and France declared war on Germany.
Option 2: He supported the Republicans against the Nationalist forces of Francisco Franco in the Spanish Civil War.
