PLS DO NOT PUT A LINK IT IS A VIRUS Which factor can increase both potential energy and kinetic energy of an object?

Increase in speed
Increase in mass
Decrease in temperature
Decrease in height from the ground

Imagine you have a five-step food chain. If 100 percent of the energy is available at the first trophic level, what percentage of energy is available at the highest trophic level

Explanation:

hope this helps

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

explanation:

this transfer is call conjunction
