A "TT" (tall) plant is crossed with at "tt" (short) plant. What percentage of the offspring will be tall?

100%

Explanation:

My biology teacher taught me the FOIL method. F=first, O=outside, I=inside, and L=last.

TT x tt

The first letter of each parent together would be Tt, T=tall so the plant would be tall, 25%

The outside letter of each parent together would be Tt, T= tall so the plant would be tall, 25%

The inside letters of each parent together would also be Tt, T=tall so the plant would be tall, 25%

The last letter of each parent together would also be Tt, T=tall so the plant would be tall, 25%

Each outcome has a T, and that is dominant so therefore, the plants will always be tall. You could also think about it as a letter has to be passed down to each child and the first plant only has capitals to pass and the second only has lowercase to pass down.

100% of the offspring will be tall.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
