Which vitamin can be synthesized in significant amounts by humans and, therefore, may NOT be essential

Answers

Answer:

The correct ansqwer is- Vitamin D

Explanation:

Vitamin D is the vitamin that can be synthesized by the human body itself therefore it is not an essential vitamin for human beings. Human skin is the part that helps in making this vitamin in humans.

The natural form of vitamin D is vitamin D3 which is formed by the sunlight exposure on the skin. When we expose our skin in the sunlight the UV radiation penetrated our skin and converts provitamin D3 into pre-vitamin D3 then this previtamin can be isomerized into the natural form of vitamin D Which is vitamin D3. So the right answer is vitamin D.

She concludes the fish populations are always large close to the coasts throughout all oceans. Why is this an invalid scientific conclusion? a. She needs less data to draw conclusions.
b. Scientists should repeat this experiment at different sites to draw conclusions.
c. Scientists require laboratory-based experiments to draw conclusions.
d. Scientists always need long-term observations to draw conclusions.

Answers

Answer:

Option B

Explanation:

When ever a scientific research or experiment is conducted , it is made sure that the results obtained are consistent through multiple trials. Here , only two trials are done i.e one on coast of California and the other on the Pacific Ocean.

Since the number of samples taken for this study are not as per the standard sample guidelines and hence the result obtained can not be considered as a acceptable.

Thus, option B is correct

Wild plants are useful in agriculture because of their _____. hardy seeds
genetic diversity
rare habitats
ideal traits

Answers

Genetic diversity

Wild plants are useful in agriculture because they give "safety" to the crop. Most of the crops have plants that are very identical, and when an adversity comes, like a pest or bad weather, to which the crop is susceptible, most of the crop is extinguished because they were all very similar and therefore, all vulnerable. When wild plants are present, they offer a wider genetic diversity that will turn the crop into a more resistant crop.
The answr is B :)

B)"After much thought, I believe that the best explanation is..."
C)"Based on the observations made and experiments performed over the last fifty years ..."
D)"If sunlight shines on the right side of a plant, then the plant will grow toward the right because ..."

Answers

A scientific theory is an explanation that is tested by the scientific method. "If sunlight shines on the right side of a plant... " is a description of a scientific theory. Thus, option D is correct.

What is a scientific theory?

A scientific theory has been a detailed and thorough explanation of the topic idea of the universe and natural world by the use of scientific methods and investigations including the hypothesis and facts.

A theory must be testable and can be falsifiable by various experiments and observations. It follows several steps of scientific methods to determine the observations and reach conclusion.

The phrase, "If sunlight shines on the right side .." is a theory as it starts with "if" which suggests that the idea of the sunlight and plant growth is explained by testing the hypothesis.

Therefore, option D. "If sunlight .." is a scientific theory.

Protein combined with ____________ in a post-exercise meal increases glycogen synthesis more than just carbohydrate alone. A. water B. fat C. minerals D. carbohydrate

Answers

Answer: Carbohydrate.

Explanation: The post exercise diet includes carbohydrates and protein. The diets that are rich in carbohydrates and protein increases the glycogen synthesis.

The rate of glycogen synthesis will be slow if it solely contains carbohydrates and in combination with protein the glycogen synthesis is fast.

The food like chicken, eggs, milk, rice fruits and other sources of protein and carbohydrates can be used as a source of energy. Post exercise there is a deficiency of glycogen in the body as the body utilizes all the stored energy during the time of exercise.

Protein combined with __carbohydrates__ in a post-exercise meal increases glycogen synthesis more than just carbohydrate alone.

c. Use of intermittent auscultation requires a lower nurse-to-patient ratio.

d. More nurses are needed when electronic fetal monitoring is used because of increased medical interventions.

The ANSWER is c.

c. Use of intermittent auscultation requires a lower nurse-to-patient ratio.

Explanation:

a. There must be a 1:1 nurse-to-patient ratio regardless of the method used.❌

A one-to-one ratio is important at the second phase of labor or in occurrence of a high-risk condition, irrespective of the monitoring method applied.

b. Staffing patterns do not influence fetal monitoring choices.❌

Staffing patterns do have an influence in conserving safe monitoring routine of the labor patient.

c. Use of intermittent auscultation requires a lower nurse-to-patient ratio.✔

Intermittent auscultation is largely staff-intensive.

d. More nurses are needed when electronic fetal monitoring is used because of increased medical ❌

Reduced nursing time is needed when carrying out electronic monitoring, this will allow the nurse to have increased time for educating, encouraging and supporting the laboring woman.
