A chemist wants to show how the molecular structures of the major greenhouse-effect contributors allow them to
absorb heat.
Which of the following would the chemist not be modeling?
A) carbon dioxide
B) carbon monoxide
C) chlorofluorocarbons
D) nitrous oxide
E) methane gas

Answers

Answer:

Option C is the correct choice

Explanation:

The major contributor of green house effect are

a) Carbon dioxide (CO2)

b) Carbon Mono-oxide (CO)

c) Nitrous oxide

d) Methane

e) Ozone

The chlorofluorocarbons (CFCs) is a man made green house gas and hence the chemist will not model it as it does not allow to absorb heat. Instead it leads to non ending chain reactions with the ozone layer thereby degrading it and hence allow entry of harmful UV rays.

Option C is the correct choice

If a microscope has a 40´ objective lens in place and a 15´ ocular lens, the total magnification of the microscope system under these conditions is

Answers

Answer:

600`

Explanation:

The total magnification of a microscope is obtained by multiplying the magnifying power of the ocular lens and that of the objective lens.

Mathematically.

Total magnification = ocular magnification x objective magnification

In this case, ocular magnification = 40`, objective magnification = 15`

Total magnification of the microscope system = 40 x 15

                 = 600`

Hence,  the microscope system under these conditions would be 600`.

Answers

Answer:

Using your gloved hand to apply pressure on the wound to control bleeding. b. Direct pressureBleeding that can be seen coming from a wound. a. External bleeding The escape of blood from an artery, vein, or capillary inside the body. d. Internal bleeding A tight band placed around an arm or leg to constrict blood vessels in order to stop blood flow to a wound. g. TourniquetBlood vessels that carry blood from all parts of the body to the heart. f. Veins Vessels that transport blood to the capillaries for distribution to the cells. e. ArteriesA bandage applied snugly to maintain pressure on the wound to control bleeding. c. Pressure bandage

Explanation:

Direct pressure is a technique used to stop the bleeding on the wound. The person should place both hands over the wound and press firmly till doctors arrive. With this first aid technique, we prevent excessive blood loss, which can cause worse problems in the future.

There are two types of bleeding, external and internal. In the first one, the skin opens, and blood comes out to the exterior. In the second one, the skin is not open, so the blood does not come out to the exterior, but blood goes to tissues around the broken vessel due to an internal injury.

A tourniquet is a first-aid technique use to stop blood flow and prevent that the injured person bleeds out till death. A band, a piece of shirt, or a belt should go around the limb and tie it hard to stop the blood flow and allow the patient to arrive at the hospital. It is a technique usually use when there is a wound that affects the main vessels.

There are different types of vessels. They change in size and structure. Veins are the vessels that carry blood back to the heart, where it will go to the pulmonary circuit to be oxygenated. Arteries will take the oxygenated blood from the heart to the rest of the body. The arteries branch into small vessels called arterioles, and the arteries branch into capillaries which will give oxygen to the cells.

A pressure bandage controls bleeding and prevents the injury from being contaminated. The pressure bandage does not restrict blood flow as a tourniquet.

Explanation:

See, when you eat something it goes down the esophagus and into the stomach, then to your small and large intestine. While it slowly travels through your intestines, your body is slowly taking the nutrients from that piece of food, which makes the food turn into a different color, since all the nutrients is taken out of the food, then the body no longer needs that food. Then it disposes from the body!

Which allele combination represents a female who is a carrier for an X-linked recessive disorder?
XRXr
XrXr
XRY
XrY

Answers

The allele combination for a female carrier is XRXr

The allele combination XRXr represents a female who is a carrier for an X-linked recessive disorder.

X-linked recessive inheritance

Females usually inherit two chromosomes X, while men inherit only one chromosome X (and one chromosome Y).

The inheritance of the chromosome X in females resembles mendelian inheritance because females have two X chromosomes.

In this case, females having the genotype XRXr are carriers because lowercase letters denote the presence of the recessive allele.

In conclusion, the allele combination XRXr represents a female who is a carrier for an X-linked recessive disorder.

A group of scientists studied the effects of exercise on insulin sensitivity in elderly women. The scientists measured the amount of insulin secreted in the saliva when given glucose. Measurements were taken at 0, 20, 40, and 70 minutes after the glucose was administered. The graph shows the data collected before and after a four-month exercise program was put into place

Which statement BEST analyzes the data shown in the graph?
A. Elderly women secrete more insulin the more they exercise.
B. Exercise decreases insulin sensitivity in elderly women.
C. Insulin sensitivity is at its highest after 50 minutes.
D. Insulin sensitivity increases as exercise decreases.

Answers

Answer:

B. Exercise decreases insulin sensitivity in elderly women.

Explanation:

I got the answer correct in a test.

Exercise decreases insulin sensitivity in elderly women.

What is Insulin?

Your muscle cells are better equipped to use any insulin that is present to take up glucose during and after exercise because their insulin sensitivity has risen.

Whether or not insulin is present, when your muscles contract during activity, your cells can absorb glucose and utilise it as fuel.

Depending on how long you exercise for, among other things, will determine how your physical activity affects your blood sugar levels.

Learn how your blood sugar changes as a result of activity. You can better understand the advantages of exercise by monitoring your blood sugar levels more frequently before and after exercise.

Therefore, Exercise decreases insulin sensitivity in elderly women.
