Answer:

Gravitational potential energy is greatest at the highest point of a roller coaster and least at the lowest point. Kinetic energy is energy an object has because of its motion and is equal to one-half multiplied by the mass of an object multiplied by its velocity squared.

Explanation:

From what majority science textbooks say is that potential energy is when an object has the ability to move, but it doesn't... that is not word for word, but I hope it helps.

1. Other than having many features in common, state other characteristics of species 2. Give reasons for the loss of energy from

Natasha2012 [34]

Answer:

As a metabolic heat.

Explanation:

The loss of energy from one trophic level to the next in a food chain occurs because energy is lost in the form of heat when the organisms from one trophic level are consumed by organisms from the next level. Only 10% of energy is transferred from one trophic level to another while the remaining 90% energy is lost in the form of heat energy in the ecosystem.

Beginning with a cell that just fertilized ( 1 cell ) how many times must it divide to become a 64 cell blastomere ?

natka813 [3]

A cell that just fertilized has to divide 6 times to form a 64 cell blastomere.

Explanation:

Human reproduction begins with the fusion of male gamete sperm and female gamete ovum. The fusion of sperm and ovum forms the zygote that is diploid. The zygote then undergoes mitotic division to develop into embryo.

The zygote first divides into two and the two individual cells divide again to form four individual cells and so on. Thus the number of cells after each division can be represented by the equation $2^n$ where n is the number of divisions. in the question it is given that the blastomere has 64 cells.

$2^n=64$

n=6

This means that the fertilized cell has to divide 6 times to develop into 64-celled blastomere.
