Answer:
The skinfold method, the measurement of subcutaneous fat folds, is the most widely adopted field method for the assessment of body fat, especially in children.
It is based on the principle that fat is of a known density and by “summing” measurements of subcutaneous fat thickness across the body, total and regional fat can be estimated.
Skinfold thickness measurements are typically used to rank individuals in terms of relative total “fatness”, or to assess subcutaneous fat at various regions of the body.
Population specific equations are used to derive estimates of percent body fat.
In infancy, it might be the sole tool available for assessing body composition longitudinally as other methods may not be feasible, or may only be suitable for use at body sizes e.g. PEA POD, can only measure infants up to 10kg.
Answer:
A
Explanation:
The correct option that does not describe the science of nutrition would be <u>that many studies have been conducted on the association between certain types of cancer and diet and, therefore, these links are well-understood</u>.
<em>While truly indeed many studies have been conducted linking certain types of cancer and diet, scientists are far from understanding the link between diets and cancer. While some degrees of understanding exists, it is not 100% certain that there is a cause-effect relationship between these two factors, and a large percentage of cases of cancer are caused by factors that cannot be controlled.</em>
The correct option is, therefore, A.
Answer: The correct answer is- Polymerase chain reaction.
Polymerase chain reaction is a technique in molecular biology that is used to produce multiple copies of a piece of DNA molecule through multiple cycles of three stages that are-
1) Denaturation- The two DNA strands are separated ( so that template DNA are exposed) at higher temperature.
2) Annealing- Primers ( forward and reverse) are attached to the template DNA.
3) Extension- New DNA strand is synthesized using enzyme Taq polymerase that adds dNTPs ( deoxyribonucleoside triphosphate) according to the complementary sequences in the template.
Answer:
The correct answer would be B) theory: hypothesis.
A hypothesis refers to the proposed or tentative explanation of any physical or natural process.
It usually provides the first step of any research or experiment.
It is highly testable as it is tested with the help of a number of scientific experiments and observations et cetera.
In contrast, a scientific theory is a well-proven explanation of aspects of the natural world. It is based on facts which have been confirmed through experiments and observation.
