Answer:
All the puppies have black hair because albino alleles are found in two different genes.
If we let the letters A and B represent the two different pigmentation genes, the one of the dogs is AAbb, and the other is aaBB.
Their offspring are AaBb and so there are not albinos because they have one dominant copy of each gene.
They use a hygrometer. It measures relative humidity (the amount of moisture in the air) A psychrometer is an example of a hydrometer
Ecosystem an area where plants, animals, and other organisms, co-ordinate for their living. According to energy pyramid, ecosystem can support fewer foxes than grasshoppers.
<h3>What is energy pyramid?</h3>
Energy pyramid is the flow of energy from one tropic level to another which is always erect.
After each level, 90% energy is lost in environment as heat. There is loss of energy at each tropic level.
As foxes comes after grasses in energy pyramid, so the ecosystem can support fewer foxes than grasshoppers.
Thus, the correct option is A.
