Why would a mutation in a gamete have more profound biological consequences than in a somatic cell?
ArbitrLikvidat [17]
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!

Have your ideas about what happens to molecules in the liquid, solid, and gas phase changed? If so, how? What evidence supports
Westkost [7]

Various states of matter have molecules moving at different velocities.

<h3>Molecules in matter</h3>

Matter is composed of molecules. These molecules that compose matter are in constant random motion. The kinetic energy and velocity of the molecules depends on the state of matter.

Molecules of a gas are fastest followed by molecules in a liquid. Molecules in a solid do not move at all hence solids have a definite shape.
