Answer:
DNPH - 2,4-Dinitrophenylhydrazine
Explanation:
This is a chemical compound used for quantitative identification of Ketones and Aldehydes in a sample.Since the urine analysis shows positive results for ketone and aldehydes,this is the test for the this. It is usually marked with yellow/orange precipitate(ppt) (dinitrophenylhydrazone).The latter is formed as a results of condensation reaction.
DNPH is a solid compound whose color changes from red to orange, when used to test for the carbonyl groups.Red when pure.
To conduct the test 1-2drops of the sample is dissolved in 2 ml of ethanol.
This should be added to about 3ml of DNPH,and shake severely for the solute and solvents to mixed up.
Usually, a precipitate should formed afterwards.However,if this did not appear, 15 minutes intervals should be observed for the precipitate( yellow or orange ppt) to appear.
The color of the precipitate depends nature of the carbon molecule or hydrocarbons in the sample. Thus, if the sample is aromatic that is unsaturated hydrocarbon e.g benzene red ppt appears, However, if straight hydrocarbon molecules (aliphatic) Orange ppt appears.

this is because C says you hold it for 3 seconds and your walking backwards which is not true for doing a push up. A is standing and doing an exersice so thats not a push up. D is saying you lie on your stomach. Thats also not a push up.
Push-ups have just a minor direct effect on the abdominal region because they primarily target the muscles of the upper body. Thus, option B is correct.
What are the benefits of doing push-ups?If and only if the calories burned during exercise are sufficient to convert fat loss and enhance abdominal muscle, push-ups can help reduce belly fat.
The push-up aids in strengthening and muscle growth across the upper body.
Improved cardiovascular health and greater shoulder joint support are two more potential advantages. Daily push-up practice does carry certain hazards, though. These include elbow injury, wrist pain, and lower back pain.
Targeted muscles include the pectoralis major in your chest, the triceps in your arms, and the shoulders (especially the scapular changing muscles).
Therefore, place palms shoulder-width apart describes the movement progression for a regular push-up.

Studies report that the differences in the time obese and lean people spend lying, sitting, standing, and moving account for about_______cals per day
Answer:
approximately 350-500 calories per day
Explanation:
It has been shown that obese and lean people's calorie needs are different despite having the same daily activities (for example, sitting and walking). These variations can be associated with different factors including height, weight, sex, age, physical condition, muscle mass, etc. At comparable body weight, lean people need less energy than obese. In this regard, it is important to note that people that have regular exercise routines burn fewer calories when doing the same activity. Moreover, lean people have proportionally more muscle mass than obese people, and thereby they are capable of burning more calories in the same unit of time.
