How does research into natural selection and traits help you understand why some butterflies have coloration that looks like the
QveST [7]

Answer/Explanation:

Natural selection - over time - selects for traits that improve fitness. A butterfly with wing coloration that looks like a hungry owl would certainly be a deterrent to their natural predators, such as smaller birds. This is because the owl is the predator of the smaller birds, and their instinct is to avoid the owl.

If a mutation arose that resulting in coloration that looked like an owl, (or at least slightly menacing) this would be beneficial to the butterfly, as it would be more camouflaged from predators. This means it would be more likely to reach reproductive age and pass the mutation onto its offspring, who would also have a competitive advantage.

Over time, this would lead to a population of butterflies with coloration that looks more and more owl-like .

What would the result be if a drug that blocks the action of rna polymerase was introduced into a virus-infected organism?
Svetllana [295]

Answer:

The correct answer is: viral replication would stop.

Explanation:

Drugs that block the action of RNA polymerase in viruses are called antivirals and are used to cure viral infections like Hepatitis and Herpes.

<u>Antivirals do not destroy the virus but rather mess with its development by inhibiting its replication</u>.

Viruses do not have the capacity to replicate or synthesize proteins by themselves, so they need a host that can "lend them" the structures needed to perform those processes. If the drug blocks the RNA polymerase, the virus won't be able to replicate itself.

Do some organisms outcompete eachother
Helen [10]

Yes, Organisms compete for the resources they need to survive like food, air, water, space. In areas where these are sufficient, organisms live in comfortable co-existence, and in areas where resources are abundant, the ecosystem boasts high species richness (diversity).

True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.
Bond [772]

Yes. True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.

The neural crest, which forms early in the development process in vertebrate embryos, is a fold on the neural plate where the neural and epidermal ectoderms converge. As an embryo grows, the neural crest produces neural crest cells (NCCs), which can differentiate into a variety of different cell types and contribute to tissues and organs.

The notochord is a temporary structure that plays a crucial role in higher animals. It secretes substances that communicate with all neighbouring tissues, telling them where they are and what will happen to them.

Therefore, True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.
