A scientist adds 5 mcg of the mineral cadmium to the daily diet of 100 4-week-old laboratory mice. After twelve weeks, the researcher weighs and takes blood samples from each mouse. According to her findings, the mice lost weight during the 12-week period and they have abnormal levels of certain hormones in their blood. Based on this information and your knowledge of scientific research, what would you tell the researcher about her findings?
A. She needs to conduct more tests on the animals' blood, because her findings are
incomplete.
B. The findings are not meaningful or valid because of the way she designed her study.
C. Her results are very interesting and she should report her findings to nutrition scientists, so
they can repeat her study and confirm the results.
D. The findings need to be summarized in a research article for submission to a peer-reviewed
nutrition journal.

Answers

Answer 1

Answer:

B. The findings are not meaningful or valid because of the way she designed her study.

Explanation:

In a scientific experiment, a control group is a group of individuals/subjects that do not receive the experimental treatment. The control group is used to determine how much of an impact a treatment (in this case, cadmium intake) has on the variables being examined in the participants who are subjected to the experimental treatment. In any experiment, it is imperative to include a control group in order to validate experimental results. In this case, it is not possible to confirm that the loss of weight and abnormal hormone levels are due to cadmium uptake because only a control group would elucidate the contribution of cadmium intake on the variables being tested.

Prejudice
Stereotypes
De jure segregation
De facto segregation
Intersectionality

Answers

Answer:

De facto segregation

Explanation:

The term "De facto segregation" refers to a type of segregation that is not maintained by laws and legal concepts, but rather maintained by society's prejudice and personal choices. The "Separate but equal" doctrine is an example of this type of segregation, as it was created out of people's conviction that blacks and whites could not share the same public environment. This doctrine was not created by laws, but by prejudice rooted in society.

Ted coordinates his carbohydrate intake from all sources to balance with the insulin injection that he gives himself each time he eats. Based on this information, Ted must have which of the following diseases?

a. Diverticulitis
b. Type 2 Diabetes
c. Ketosis
d. Type 1 Diabetes

Answers

Answer:

d. Type 1 Diabetes    

Explanation:

Type 1 Diabetes attacks the beta cells in the pancreas. The beta cells produce insulin, a hormone that allows glucose in our bloodstream to enter the cells for their functions and to store it for when the body needs it in the future. In type 1 diabetes, the body does not produce insulin, so there are high concentrations of sugar in the blood, which can be dangerous. A person with type 1 diabetes has to inject insulin, coordinating it with the carbohydrate intake so that glucose can enter the cells.

Fat-soluble nutrients are carried to the liver from the intestine via the hepatic portal vein.

Answer:

Hope this is helpful

True, Fat-soluble nutrients are carried to the liver from the intestine via the hepatic portal vein.

What is nutrients?

A nutrient is a substance used by an organism to survive, grow, and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi, and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures, such as hair, scales, feathers, or exoskeletons. Some nutrients can be metabolically converted to smaller molecules in the process of releasing energy, such as for carbohydrates, lipids, proteins, and fermentation products (ethanol or vinegar), leading to end-products of water and carbon dioxide. All organisms require water. Essential nutrients for animals are the energy sources, some of the amino acids that are combined to create proteins, a subset of fatty acids, vitamins and certain minerals. Plants require more diverse minerals absorbed through roots, plus carbon dioxide and oxygen absorbed through leaves. Fungi live on dead or living organic matter and meet nutrient needs from their host.

Different types of organisms have different essential nutrients. Ascorbic acid (vitamin C) is essential, meaning it must be consumed in sufficient amounts, to humans and some other animal species, but some animals and plants are able to synthesize it. Nutrients may be organic or inorganic: organic compounds include most compounds containing carbon, while all other chemicals are inorganic. Inorganic nutrients include nutrients such as iron, selenium, and zinc, while organic nutrients include, among many others, energy-providing compounds and vitamins.

Which blood vessels play a key role in regulating blood distribution and pressure because their diameters may be easily and rapidly adjusted?

Answers

Answer is Arterioles

Arterieole is blood vessels play a key role in regulating blood distribution and pressure because their diameters may be easily and rapidly adjusted.

What is Arteriole?

A microcirculation blood vessel with a small diameter known as an arteriole extends and branches from an artery to lead to capillaries. The main site of vascular resistance is found in arterioles, which have muscular walls with typically only one to two layers of smooth muscle cells.

The transition from arterioles to capillaries is where blood pressure and blood flow velocity vary the most.

This function is crucial because it stops the one-layer, tiny capillaries from blowing up under pressure. The arterioles are responsible for this pressure drop since they have the highest resistance of all the peripheral blood vessels, which results in a significant drop in pressure.

Therefore, Arterieole is blood vessels play a key role in regulating blood distribution and pressure because their diameters may be easily and rapidly adjusted.
