lys-0071 [83]

Answer:

According to the warning signs that exist in radiology clinics, a pregnant woman should consult her physician before undergoing an x-ray study because x-rays are a form of ionizing radiation that can affect the development of a gestational baby.

Explanation:

<em>Signs/notices in radiology clinics indicate that women who are pregnant or suspect they may be pregnant should consult their doctor before undergoing a radiological examination. Why should they do it?</em>

X-rays are a type of electromagnetic radiation -ionizing- capable of passing through the body, used to obtain images of the interior of an organism by capturing these rays on photographic film.

It is well known that X-ray radiation can have mutagenic effects on living organisms, according to the amount of radiation and the time to which it has been exposed. In the pregnant woman, who has a fetus developing inside her, special attention must be taken due to the harmful effects that ionizing radiation can have on its development. This is the main reason why a pregnant woman should consult her doctor before undergoing a radiological study.

5. Which of the following is an example of active transport?
Nadusha1986 [10]

Answer:

D (proteins moving ions from low to high concentration across a cell membrane)

Explanation:

Active transport, by definition, is a type of substance transport that requires energy (typically in the form of ATP). Having said that, we can immediately eliminate B (aka water diffusion throughout the cytoplasm of a cell), as diffusion (osmosis in this case) does not require any expenditure/spending of energy. Next, we can cancel A and C because although they do require energy, there is no transport involved. Thus that leaves us with D. D is not only the answer because of the process of elimination but also b/c the ans. choice says that ions are being moved from low to high concentration, which is against the concentration gradient and thus requires energy. Hope you found this helpful! :)

Explain, using natural selection, how the beetle population will adapt over time.
Julli [10]

Answer:

Over time the beetle population will adapt as a result of natural selection because the beetles "desired" by the birds will be eaten and their population will dimish as a result. The beetles that are not eaten by the birds will have a chance to allow their population to grow because a. they aren't being eaten and b. they have more space as the other colored beetle's population is shrinking. Causing the eaten species to become less prominant and the not eaten beetle's population to grow and take over in place of the other beetles.
