What would you expect to happen to levels of mevalonate in human plasma if an individual were to go from a meat-containing diet

enyata [817]

Answer:

increase

Explanation:

The mevalonate pathway is known to generate isopentenyl pyrophosphate and dimethylallyl pyrophosphate, which are used to synthesize diverse compounds including cholesterol and steroid hormones. The levels of mevalonate in human plasma may be used as a measure of cholesterol synthesis. When the cholesterol level is low, it stimulates its endogenous production by the mevalonate pathway. Since it is well known that the vegetarian diet reduces cholesterol, this diet also increases mevalonate levels.

A man heterozygous for blood type A marries a woman heterozygous for blood type B. What could be the possible blood types of the

GenaCL600 [577]

Answer:

Heterozygous A: AO (remember, O type blood is a recessive allele. It's masked by A)

Heterozygous B: BB (h0m0zygous)

AO x BB --> AB, BO

Therefore, the genotypes of their offspring will be 1 AB to 1 BO, while the phenotypes will be 1 AB blood to 1 B blood.

I hope this answer helps you find what your looking for! :)

In cats, black fur color is caused by an x-linked allele; the other allele at this locus causes orange color. The heterozygote i

Luden [163]

The offspring that will be produced in the cross would have tortoiseshell fur.

<h3>X-linked traits</h3>

In cats, the male is XY while the female is XX.

Assuming that black fur is caused by the allele B and the orange fur is caused by A

A black female will have the genotype $X^BX^B$

An orange male will have the genotype $X^AY^A$

Crossing the two: $X^BX^B$ x $X^AY^A$

Offspring: $X^BX^A$ , $X^BY^A$ , $X^BX^A$ , and $X^BY^A$

$X^BX^A$ = tortoiseshell fur female

$X^BY^A$ = tortoiseshell fur male

Which traits are challenges of life for all organisms? Choose all answers that are correct.

Varvara68 [4.7K]

<span><span>a. </span>Reproducing</span>
d. maintaining structure
f. obtaining energy

These three traits definitely standout as a challenge for every living creature in the ecosystem. In Darwin’s Natural Selection Survival of the fittest: being fit is one category in order to survive the wild, in other words, being flexible. Reproduction is battle royale in both humans and animals, even for plants too. Why? Because the ecosystem changes, the weather changes, the food chain is a combat to chase. Some can’t even reproduce due to hereditary or physical causes. Energy is as important as living. If plants can make their own food how about the carnivores and the omnivores. Food is a challenge. Structure is sustaining the capacity and ability to hunt and survive. Important and a by-product of obtaining energy.
