Duncan was a subject in a clinical study that was designed to determine the effects of certain diets on health. While participat

ing in the study, he had to live in a special medical unit at the university hospital. He wasn't permitted to eat anything other than the synthetic formula diet provided by the researchers. The formula contained vitamins, choline, minerals, animal protein, purified water, and corn starch. Within a few weeks, Duncan developed patches of scaly skin on his arms and legs and bald spots on his head. When _____ were added to his formula, the signs of the nutritional deficiency disappeared.

Phantasy [73]2 years ago
6 0

Answer:

The missing options are:

- steroid hormones

- carbs

- essential fatty acids

- PHO

The correct answer is essential fatty acids.

Explanation:

Essential fatty acids are the fats that our body can not produce by itself, but that are essential for the function of the body, so we have to consume foods that have these fats, such as fish, oysters, nuts, chia seeds, soybean oil, etc. The deficiency of these fats causes skin problems, alopecia, anxiety, depression, among other things.

Match the food item to its nutrient group
ss7ja [257]

Macronutrients can be defined as the compounds which can be found in large quantities in the human diet. Majority of the energy for the functioning of the body is derived from these macronutrients. These includes the fats, carbohydrates, and the proteins.

Micronutrients can be defined as the compounds which are required by the body in small quantities, but they are essential for the proper growth of the body. These includes the vitamins and minerals.

Hence, the given food and the nutrient groups can be matched as follows:

Macronutrients - Carbohydrates, proteins, fats.

Micronutrients - Zinc, calcium.

“blank” investigations are best for demonstrating cause-and-effect relationships. a. descriptive b.comparative c. experimental
FromTheMoon [43]

C. Experimental

Explanation - The cause and effect of a process would be studied in experimental investigations. However, in descriptive studies, relationship between the factors are not studies rather the detail of the process is studied. In comparative investigation, several factors are compared and its effects are analyzed.

In experimental investigations, experiments are carried out based on the hypothesis and then it is validated accordingly. Validation is a must to prove and disprove the hypothesis. Therefore, experimental data and hypothesis are related.

Life sciences about gaseous exchange please help.​
dem82 [27]

Gaseous exchange is fundamental in aerobic organisms because oxygen is required to carry out cellular respiration.

<h3>What is cellular respiration?</h3>

Cellular respiration is a series of chemical reactions by which aerobic organisms interchange oxygen and carbon dioxide with their surrounding environment.

During cellular respiration, oxygen is consumed to generate ATP and carbon dioxide is released.

In conclusion, gaseous exchange is fundamental in aerobic organisms because oxygen is required to carry out cellular respiration.

Which of the following events characterizes metaphase of mitosis?
Natalka [10]

A.chromosomes aligning themselves at the equator.

<h3>What distinguishing features of mitosis' metaphase?</h3>

A phase of cell division known as "metaphase" (mitosis or meiosis).Individual chromosomes are typically dispersed throughout the cell nucleus.The chromosomes of the cell condense and move toward one another, aligning in the center of the dividing cell, and the nucleus of the cell disintegrates during metaphase.

<h3>What distinguishes metaphase from other phases?</h3>

Its alignment of a duplicated chromosomes at the metaphase plate, an equatorial plate, is what gives metaphase its name.Via microtubules attached to its kinetochore, one of the sister chromatids is joined to one pole of the cell, and the other sister chromatid is associated to the other pole.

Alcohol dehydrogenase (ADH) is an enzyme that aids in the decomposition of ethyl alcohol (CH3OH) into nontoxic substances. Methy
Thepotemich [5.8K]

Answer:

d. Competitive inhibition will decrease because the proportion of the active sites occupied by substrate will increase.

Explanation:

Enzymes are bio catalysts in living cells responsible for aiding biochemical reactions.

Their active sites are primary protein  3D structure  for binding with substrates during   reactions.

Enzymes reactions are usually affected by inhibitors(e.g methyl alcohol) which compete with the active site with the actual substrate(ethyl alcohol) ,

This is an example of competitive inhibition. The more ethyl alcohol available, the more active sites  occupied, therefore denying the inhibitor methylalchol  chances to the active site, thus preventing the formation of toxic formaldehyde, and more of non toxic substances from formation of more ADH-METHYL ALCOHOL COMPLEXES at the active sites
