Answer:

Beetle diversity thus appears to have resulted from multiple factors, including low extinction rates over a long evolutionary history, codiversification with angiosperms, and adaptive radiations of specialized herbivorous beetles following convergent horizontal transfers of microbial genes encoding PCWDEs.

The total energy in a system is 30J and the PE is 20J. what is the KE?
Inessa [10]

Total mechanical energy = potential energy + kinetic energy.

If we plug in our numbers:

30 = 20 + KE

Let's solve for KE:

30-20= KE

10 = KE

If we go back to the original equation:

30 = 20 + 10

Thus we know this is correct.

Pls help with answer!!!<br><br><br> will give brainliest
MariettaO [177]

Answer:

It should be A).

Explanation:

Albino is a recessive trait (denoted by bb).

If your hamster does not carry the recessive trait, that will mean that they will have to have two dominate trait (denoted by BB).

Therefore, assuming that you breed your hamster with a known albino hamster, and he has two dominate, then the offsprings will be:

\left[\begin{array}{ccc}&B&B\\b&Bb&Bb\\b&Bb&Bb\end{array}\right]

Therefore, there will be a 0% Albino showing up (recessive trait), but all will carry the recessive trait to the next offspring.

However, you receive 50% Albino offspring, thereby implying that there is already a carrier on top of the recessive breed:

\left[\begin{array}{ccc}&B&b\\b&Bb&bb\\b&Bb&bb\end{array}\right]

Therefore, your hamster does carry the albino trait.

A) Yes.
