Meiosis is a type of cell division that takes place in the sex cells where four daughter cells are formed with half the number of chromosomes as the parent (haploid, n). In this case, if the gametes were formed by mitosis then it means they would have a diploid (2n) number of chromosomes.

stiv31 [10]

Sam and Jenny ride their bikes at a constant velocity of 3 miles per hour.

Explanation:

Here we see that both of them are moving at a constant velocity which means their speed is constant and they are moving in a straight line.

Zero acceleration is implied on the bikes and the net force is BALANCED.

When forces are in balance, acceleration is zero. Velocity is constant and there is no net or unbalanced force.
