Answer:

Explanation:

If any recessive phenotypic individuals result from the cross, then the unknown individual must carry the recessive allele, and have the heterozygous genotype. A testcross helps reveal the genotype of an organism when that organism shows the dominant trait, such as agouti coat color in rats.

Hi i need help with this. can someone give me a full answer on this? thank you!
Stolb23 [73]

Answer:

Point 3 for kinetic, points 1 and 5 for potential

Explanation:

There is one point that the ball has the most kinetic energy it is at point 3. Point 3 has the most kinetic energy because it has gained the most speed since it was dropped and it also is right before it starts slowing down from trying to go up again. Points 1 and 5 have the most potential energy. When the ball is at point 1 or 5 it is at its maximum height thus it cannot swing any further, so it stops for a split second and gains a large amount of potential energy before it is released into kinetic energy when it falls back down.

xeze [42]

The unit for power in electricity should be watt. The power show how many energy transferred during a time and the SI unit would be joule per second.  

The bill is charging for the amount of energy. The energy could be calculated by multiplying the power with time. In this case, the power in kilo watt will be multiplied by the duration in hour which make the kilowatt hour.
