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:
D. Increase in temperature from 20 degrees C to 37 degree C
Explanation:
A decrease in substrate concentration might not necessarily lead to an increase in enzymatic activities.
Enzymes are pH specific. Thus increasing the pH of operation from 6.8 to 7.4 might destroy the enzyme.
Reactants need to overcome a minimum energy (activation energy) before they can be converted to products. The higher this energy, the lower the rate of reaction. Hence, increasing in activation energy will lead to a lower rate of enzymatic reaction.
<em>Enzymes work optimally at a temperature that is close to the human's body temperature which is 37.5 degrees. Hence, increasing temperature from 20 degrees to 37 degrees will result in an increased enzymatic activities.</em>
The correct option is D.
A plant-life filled biome of sorts, like a thick forest.

Answer: Only some of the organisms survive and reproduce.
Natural selection is a process of differential survival and reproduction in which organisms bearing favorable phenotypic traits survive in changing environmental conditions. Therefore, only some of the organisms survive and reproduce which have suitable phenotypic trait. For example a population of beetle bearing two colors red and green. The green colored beetles mimic the color of grass will remain undetected by birds and those with red color easily observed and detected by birds. Hence, only green beetles are favored for survival over red beetles.
