14. what are the genotypes of the brown and yellow labs who have all black puppies? show all your work using punnett squares.
Varvara68 [4.7K]

There are two different genotypes of brown labs and three different genotypes of yellow labs (eeBB, eeBb, and eebb) (Eebb and EEbb).

Let's examine genotypes, a different table now: As a result, a brown or yellow lab couple can have both brown labs and black or yellow labs.In actuality, neither brown nor chocolate dogs are permitted. Only yellow puppies can ever be born to a yellow lab couple. Even stranger, two brown labs can have yellow or brown puppies, whereas two black labs can have yellow or black puppies. Only yellow labs are capable of independently producing several shades of colour.

What is the energy brought by electron carriers to the<br> mitochondria used for?
Nonamiya [84]

Answer:

The correct answer will be- to synthesise the ATP molecules in respiration process.

Explanation:

The electron transport chain is the last phase of the cellular respiration which helps in the synthesis of a large number of ATP molecules.

The ATP molecules are synthesized when the energy generated by the movement of protons through CF₀ unit takes place.

The movement of electrons in the chain leads to the movement of proton from the mitochondrial matrix to the intermembrane space. This creates the proton gradient across the membrane which to equilibrate the protons move down the concentration gradient through ATP synthase. The energy while this is used to rotate the ATP synthase which coverts the ADP to ATP.

Thus, to synthesise the ATP molecules in the respiration process.
