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]3 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.

The cell organelle which serves as the site of protein synthesis in the cell is the ribosomes.

<h3>What are cell organelles?</h3>

Cell organelles are membrane-bound structures whivh are found embedded within a cell cytoplasm and which perform specific functions for the cell.

Some cell organelles include:

  • mitochondria
  • ribosomes
  • lysosomes
  • Golgi bodies

The ribosome is a cell organelle which functions as the site for protein synthesis in the cell.

Therefore, the site of protein synthesis in the cell is the ribosomes.

__________ can occur when part of a population of a species becomes separated from the remainder
aleksklad [387]

Answer:

The correct answer is would be - geographic isolation.

Explanation:

The geographic isolation is also known as the speciation in which biological species experience genetic changes and on the basis of the genetic changes that experienced this separated with other organisms of the species.

It is physical separation or speciation of the biological organisms on the basis of geographical barriers of two population of the same species that keep them from interbreeding and reproducing.

Thus, the correct answer is - geographical barriers.

In one experiment, scientists raised mice in germ-free conditions so the mice lacked intestinal microbes. The mice were fed a lo
Luba_88 [7]

Answer:

The answers are:

1. initial composition of microbial community (controlled variable)

2. age of the mice (controlled variable)

3. change in body fat (dependent variable)

4. diet (independent variable)

5. weight gain (dependent variable)

6. final composition of the microbial community (controlled variable)

Explanation:

Before I go ahead to explain each of the choices of classification, let us define each of the different types of variable.

1. Independent variable: this is a variable that is under the control of the experimenter. It is made up of the factors that are being tested. In our example, the independent variables is; diet. The aim of the experiment is to study the effect of the type of diet on the mice. The diet can also be varied and assigned at will by the experiment.

2. Dependent variable: a dependent variable is one whose outcome is reliant on the effect of the changes in the independent variable. It is the factor to be measured. In our example, the factors that obey these definitions are; change in body fat and weight gain. these two factors depend on the types of diet taken by the mice, hence they are the factors to be measured.

3. Controlled variable: these are variables that are kept constant throughout the experiment to rule out biases, because they produce the same effect on the dependent variable as the independent variable and must be keep constant or uniform in the test groups. in our example, the factors that are controlled include; initial and final compositions of the microbial communities and the age of the mice, because the microbial composition if not uniform among the groups can cause  biases in how the diets are processed, and the age of the mice also must be uniform to avoid age-related differences in the processing of the diets
