Answer:

We use special tools and chemicals to help us see how long and how old the dirt or soil is, and or new technology!

Explanation:

First of all, lets say you found a weird rock that you have never seen before.

It was brown with white spots, and had a name carved into it! You take it to your house and search up the name that is carved on the rock! You found a old rock that a long lost Indian tribe had used for marking the dead!

Why do we rarely see food chains with quinary (5th level) consumers?
love history [14]

Answer: Energy is passed up a food chain or web from lower to higher trophic levels. This loss of energy explains why there are rarely more than four trophic levels in a food chain or web. Sometimes there may be a fifth trophic level, but usually there's not enough energy left to support any additional levels.

What are the possible phenotypes of chicken offspring if one parent has black feathers ( FB ) and one parent has white feathers
Salsk061 [2.6K]

Answer:

None. Chickens have feathers not fur.

Now to color. The male usually determines color so without that information it is hard to answer with any authority.

In most crosses if the male is black and the hen is white you will get some black chicks and all will have white/black

variations.

If the male is white and the hen is black you will get some all

white with others showing black and white.

If the breed is Leghorn, even if the rooster is black you will

get mostly white chicks with some throwbacks in red and buff.

Sphinxa [80]

Answer:

Chloroplast.

Explanation:

This is what I believe it is since we're obviously talking about an animal cell and NOT a plant cell like it says. Animal cells do not contain chloroplast.

If this is the answer you're not looking for, let me know! Hope this helped! :)))

"Tryptophan self-controls its synthesis." Justify this statement.
Dimas [21]
Tryptophan self-controls its synthesis. If we have a large amount of tryptophan in the sense that it exceeds, tryptophan would act as a co-repressor which prevents synthesis of more enzymes for its production. Hope this answers the question.
