Atmospheric CO2 taken in by photosynthesis.

Answer:
D
Explanation:
Two genes are involved in this case: one coding for eye color and the other for skin color.
According to the question, the allele for Black eyes (B) is dominant over the allele for orange eyes (b) while on the other gene, the allele for green skin (G) is dominant over the allele for white skin (g).
This means both alleles for orange eyes (b) and white skin (g) are recessive i.e masked by their counterpart allele
Since they are recessive, they will only be phenotypically expressed if they are in their homozygous state. i.e same type of allele.
In this case, the parent has orange eyes and white skin i.e.both recessive traits
Therefore, the genotype will be bbgg.
An action potential is caused by either threshold or suprathreshold stimuli upon a neuron. It consists of four phases; hypopolarization, depolarization, overshoot, and repolarization. An action potential propagates along the cell membrane of an axon until it reaches the terminal button.
The hypothalamus is not the master gland rather "it is a connection point between the nervous and endocrine systems." Where the hypothalamus controls the basic impulses and drives of human action.
