For mitosis, two cells are created, and for meiosis, four cells are produced. So the answer is B. Because in mitosis, the chromosome replicates once and divides once. In meiosis, the chromosome replicates once and divides twice. That's why the cell has half of the chromosomes after meiosis.
The only logical answer would be C. Unicellular, but the answers seem to be all wrong.
Octopus and squid have little suction cups on their tentacles. It helps with sticking onto food (so it doesn't get away) and also helps with sticking into things. If it wanted to camouflage into some rocks, it can use its tentacles to cling to to the rock.
Tentacles can also grab and carry things. Scientists have made tests where they would put a clam in a jar with the lid screwed on. The octopus would grab onto the jar and use its tentacles to twist the lid off.
Without tentacles, octopuses and squids would be pretty helpless and probably couldn't survive in the deep ocean.
Answer:
Substitution
Explanation:
There are 3 types of mutations: deletions, insertions, and substitutions.
A deletion deletes one of the bases (AGTC), which can completely mess up the sequence and create a completely different protein.
An insertion inserts a new base into the strand, which can also completely mess up the sequence and create a completely different protein.
A substitution just changes one of the bases to a different base. This doesn't usually affect what protein is made, but when it does, it only changes one of the amino acids in the sequence, whereas the others change all of the amino acids in the sequence.
If the same protein is still created, then this person only experienced a substitution because it didn't affect the end result of the protein.
