The relationship between the hermit crabs and the snails is A.commensalism
Why? Commensalism refers to a relationship where one organism benefits from the other without affecting it. In this case, the hermit crab benefits from the snails, via the latter's discarded shells. The crab's use of the snails' shells has no impact on the snails.
Answer:
- Dependent variable: number of cells that are in one of the phases of mitosis
Explanation:
In an experiment, the independent variable is the variable that is not changed by the other variables that are being measured during the experiment (in this case, the independent variable is represented by the distances from the root cap). On the other hand, the dependent variable is the variable that is being measured/tested during the experimental procedure and, therefore, is 'dependent' on the independent variable. In consequence, in an experiment, the dependent variable is expected to change as a result of the manipulation of the independent variable.
There is quite a lot, but the fact that both mitochondria and chloroplasts have their own circular DNAis what I would call "key" evidence. That is, these organelles are not "manufactured" by the cell (i.e., there are no "genes for mitochondria" in eukaryote genomes): like their ancestral bacteria, they reproduce by binary fission.

Answer: The complimentary strand will read ATG CCC GTC GTA TTT TAG
Explanation:
The complimentary strand to the replicating DNA molecule is known as messenger RNA (mRNA).
The mRNA directs specific bases to pair the existing base on the replicating DNA strand:
- Adenine (A) pairs only with Thymine (T)
- Guanine (G) pairs only with Cytosine (C)
So, to obtain the complimentary strand of TAC GGG CAG CAT AAA ATC, substitute each letter with its base pair.
Thus, the complimentary strand will read ATG CCC GTC GTA TTT TAG
