Which statement about natural selection is true
Answer: natrual selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce
How does research into natural selection and traits help you understand why some butterflies have coloration that looks like the coloration of a hungry owl?
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 .
The nurse is caring for a client who has vesicles filled with purulent fluid on the face and upper extremities. on the basis of these findings, the nurse should tell the client that the vesicles are consistent with which condition?
The correct answer is allergic reactions, which leads to skin irritation.
The vesicles are the fluid-filled, small sacs, which can develop on the skin. The fluid within these sacs may be white, clear, or even mixed with blood. They are also sometimes considered as bullae or blisters. The development of vesicles takes place when the fluid gets occupied within the epidermis, that is, the skin's top layer.
Various health conditions can lead to the condition, however, the formation of vesicles is consistent with the allergic reactions that lead to skin irritation.

What percentage of a meal has been absorbed by the time it leaves the small intestine?
Out of the following given choices;
The answer is; D.
The Ilium is where most of the absorption of nutrients from the food we eat takes place. The ileum is well adapted for this task having a narrow lumen and well convoluted to move food slowly and give time for absorption. In addition, it has approximately 2,000 villi per square inch that increase the surface area for absorption.
What do scientists call organisms which obtain energy from the foods that they consume
Organisms that obtain enegy from the food they consume is called a heterotroph or consumer
