Answer:
Probably not much.
We exhale carbon dioxide every second.
"Burn less trees." - thank you kaliliew16
Therefore, not much can be done.. We would have to all stop breathing to stop the flow of carbon dioxide, meaning we'd all die off quickly due to lack of oxygen.
hope it helps you!
Adaptive genes are selected and passed from generation to generation.
<h3>Natural selection and the evolution of long necks in giraffes</h3>
According to Darwin's theory of natural selection, natural selection selects for adaptive genes in organisms and deselects non-adaptive genes.
Thus, adaptive genes are passed from generation to generation.
In the case of the giraffes. It is plausible that their ancestors kept on stretching their necks in order to feed as the trees they fed on kept growing taller. The taller the tree grows, the longer the ancestors of giraffes stretched their necks to reach it. Otherwise, they just might have to die of starvation.
This adaptation activated the long-neck genes in the ancestors of giraffes. Natural selection selects this trait and it was passed down across generations.

Answer:
3.
Explanation:
genotypes are traits embedded in the genes that cannot be observed whilst, a phenotypes are traits that are physically displayed by the body and therefore, can be observed.
example,
genetic factor - brown colored eyes.
connotation for the gene - B
Genotype - BB.
phenotype - brown colored iris.
