Environmental pollutants such as PCB's and the pesticide DDT are fat-soluble, non-biodegradable, and contaminate oceans and other aquatic systems. Plankton in the ocean become contaminated by these chemicals and pass them along through the food chain. A pregnant woman has been cautioned to limit her consumption of food that may be high in PCBs. If she consumes food from a nearby contaminated ocean, we would expect that the most contaminated foods would be ___________.

Answers

Answer 1

Answer: a. fish that eat shrimp.

Explanation:

The PCB's are said to contaminate plankton which then pass them along the food chain including to shrimp which eat plankton. The shrimp will therefore be expected to have higher levels of PCB than plankton because the shrimp eat multiple infected plankton thereby accumulating PCB in their system.

Fish that then eat the shrimp will therefore have even larger amounts of PCB than the shrimp for the same reason as above. Eating the fish would therefore present the most contaminated source to the woman.

What are the avantages of an MRI scan over an xray?

Answers

Answer:

One big advantage to an MRI scan is that there is no exposure to radiation as in the case with X-rays, CT scans, and PET scans. This means MRI can be used more safely on people who are particularly vulnerable to the effects of radiation, such as pregnant women and babies.

MRI also has the advantage over X-ray because it can identify swelling and inflammation. It can show both three-dimensional and cross-sectional images of the body.

Imagine you have your own blog. You want people to know the truth about teens and drugs. Write a paragraph to post on your blog that explains that most teens do not use tobacco, alcohol, or other drugs. PLS HELPP

Answers

Answer:

Although it is true that the use of recreational drugs, especially tobacco, alcohol or cannabis, is relatively common among adolescents, it is also true that the percentages in which this situation occurs do not exceed 20% of the total number of adolescents of the country. In other words, only 1 in 5 children under 18 years of age regularly use any of these three substances, while 80% stay completely away from their use. In this way, it is a concept that undergoes a generalization that is not true, but on the contrary a fallacious attribution to a whole group of people.

How many chambers in the Hart?

(Pringles)

Answers

Explanation:

The heart has four chambers: two atria and two ventricles.

The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.

The right ventricle pumps the oxygen-poor blood to the lungs.

The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.

Answer:

4

Explanation:

The heart consists of four chambers in which blood flows. Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.

A truck was carrying a substance in a tank. The molecules of that substance were moving away from each other . The truck parked overnight in a place where energy transferred out of the substance

Answers

Answer:

The missing parts of the question and options are:

In the morning, the substance was a gas. How were the molecules moving in the morning?

a. They were moving more slowly away from each other.

b. They were moving more slowly in place.

c. They were moving more slowly around each other.

d. They were moving more quickly around each other.

The substance cooled down, but why was it still a gas?

a. The molecules are so attracted to each other that they need much more energy transferred in to change phase.

b. The molecules are so attracted to each other that they need more energy transferred out to change phase.

c. The molecules are not very attracted to each other, so they need much more energy transferred out to change phase.

d. The molecules are not very attracted to each other, so they need much more energy transferred in to change phase.

The answers are:

a. They were moving more slowly away from each other

c. The molecules are not very attracted to each other, so they need much more energy transferred out to change phase.

Explanation:

If the substance is a gas, the molecules collide with each other, and they drift apart. The intermolecular forces between molecules are weak. As a result, when they bump with each other, they do not get attached. Usually, in a gas, the molecules move fast in all directions, and they gain energy with their collisions. However, in this case, they move slowly because the substance lost energy overnight. If the substance loses more energy, it becomes a liquid, and its molecules would be more attracted to each other.
