The third option: Increase the intensity of cardiovascular workouts, is the right one. we know this because the rest of the options don't give the right fit. anaerobic workout is a short burst of energy, so it wouldn't be a good fit. Doing fewer aerobic workouts would lower it even more. Decreasing intensity of a cardiovascular workout would also cause a larger decrease. so it is the third option. Hope this helps a lot.

Answer:
bright blue trait = recessive
yellow trait = dominant
Explanation:
let the letter B represent the gene for skin colour.
This means that the dominant gene is 'B' while the recessive gene is 'b'
A dominant gene is one that is exhibited phenotypically in the presence of both gene variants (heter0zygous state - Bb) while a recessive gene is only expressed phenotypically when it is in a h0m0zygous state (bb)
In order to find out the genotype of the parents, let us consider each cross one after the other.
1. A bright blue female and a bright blue male produce all blue progeny.
2. A yellow female and a yellow male produce a mix of both bright blue and yellow progeny
From statement 2, it can be deduced that the trait for yellow colour is dominant because a cross of the parents exhibiting this trait produces bright blue offsprings too, meaning that the genetic composition of the parents contains the gene that codes for yellow colour. Since these parents show a yellow colour in a heterozygous state, then the trait for yellow colour is dominant.
Therefore, the genotypes of the parents in each case include:
1. A bright blue female and a bright blue male produce all blue progeny. (bb × bb)
2. A yellow female and a yellow male produce a mix of both bright blue and yellow progeny (Bb × Bb)
I think we should not throw our rubbish everywhere’s
