So the main difference here is that a somatic cell is all the cell's in your body except for your reproductive cells. Those reproductive cells are called gametes. So, when a mutation occurs in a somatic cell, it really doesn't do much because it's one cell out of trillions in your body. However if a mutation occurs within a gamete, that gamete gets inherited in the offspring during sexual reproduction, and become the *blueprint* for an entire human being. That small mutation would be present in every cell throughout the whole body. Thus, that is why a mutation in a gamete, has much more severe biological consequences vs a mutation in a somatic cell. Hope this helped!
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.
The first sentence is true
The remains of a Hadrosaur are an example of a fossil typically structures like bones shells and teeth fossilized more often then things like tissues or plant leaves.
