Cells are created from existing cells is the part of the
cell theory which explains why the skin is able to repair itself. The body
produces 300 million new cells every day. After getting a cut or scratch, the
skin may start bleeding. This happens when the injury tears down the tiny blood
vessels that is found under the skin’s surface. The body wants to stop the
bleeding so the platelets will come to the rescue.
At the cut, platelets stick together. This is how the blood
clots which then become a scab. This protects the area so the cells underneath
it can have the time to heal. Beneath the scab, new skin cells multiply to
repair the wound. Damaged blood vessels are restored and blood cells end the infection
in the wound. And also, under the scab, a new skin layer is formed.
Answer:
Enzymes proofread the DNA after the DNA has been replicated and replace any mismatched nucleotides.
Explanation:
DNA replication occurs to make exact copy of original DNA. Transcription of genetic information to an intermediate mRNA occur after replication after which we have translation of genetic information into amino acids.
In the process of replicating DNA error can occur and then enzymes proofread the work for errors. Enymes DNA polymerase proofs read the replication,removes and replace the nucleotide base from where error occurs. It proof read after the DNA replication has occured.
This enzyme is also involve in DNA replication.
For some reason I thought it was D) cellular respiration as C) photosynthesis dealt with plants and light.
The answer is C. A mycorrhiza is a symbiotic association
between a fungus and the roots of a vascular host plant. They colonize the roots
of vascular plants connect them, one to the other; and then send out their
filaments, called hyphae, as much as 200 times farther into the soil than the
roots they colonize.
