Joel is comparing two slides showing chromosomes in a sperm cell and a skin cell of a dog. He finds that the sperm cell has 39 c

Sphinxa [80]

Answer:

The total number of chromosome in a skin cell is equal to 78

Explanation:

The sperm is usually haploid i.e it will contains only half of the total chromosome number.

Therefore , if the total number of chromosomes is "n" , then the number of chromosome in the sex cell will be "n/2"

Thus, 39 chromosome is just the half of total chromosome number.

Now a skin cell is a diploid cell and it will contain all the chromosome i.e "n"

As we know

$\frac{n}{2} = 39\\n = 39 * 2\\n = 78$

Hence, the total number of chromosome in a skin cell is equal to 78

Potential Energy on the way up the rollercoaster

Nana76 [90]

Answer: Because The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill. Once you start cruising down that first hill, gravity takes over and all the built-up potential energy changes to kinetic energy. Gravity applies a constant downward force on the cars.Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released. Gravitational potential energy is potential energy that results from an object's position in a gravitational field, and is equal to the object's weight multiplied by its height.

hope this helps have a nice day❤️
