Answer:
Explanation: The possible genotypes from this cross are Rr, rr, Rr, and rr. So, that means two offspring will be red and two will be white. The percentage chance for each phenotype is: 50% chance for red flowers and 50% chance for white flowers.
Answer:
The correct answer is b. recognizes foreign DNA sequences that have previously entered the cell and directs the Cas proteins to destroy them.
Explanation:
Clustered regularly interspaced short palindromic repeats (CRISPER) is the sequences of DNA found in the genome of prokaryotes and archaea. These sequences are added at a crisper locus in DNA by bacteria through capturing bacteriophage DNA during infection.
Then this sequence is used to detect a similar sequence of bacteriophage during subsequent infection and destroy them by Cas9 enzyme. Cas 9 enzyme uses a crisper sequence as a template to destroy similar phage DNA.
So the CRISPER Cas system provides an adaptive defense mechanism to bacteria against foreign DNA coming from bacteriophage. Therefore the correct answer is b.
Answer:
Mast cells are a type of white blood cells that is found in connective tissues all through the body, especially under the skin, near blood vessels and lymph vessels, in nerves, and in the lungs and intestines.
Answer:
It would be increased basically by increasing the surface area of the cell
Explanation:
Like take the mitochondria for example the folded membrane increases the surface area without affecting the volume
