Answer:
B
Explanation:
DNA replication is semiconservative- meaning the old template strand will form a double helix with the newly synthesized strand. The DNA polymerase can only replicate DNA in the 5’ -> 3’ direction on a DNA strand. However, because the two strands of a DNA double helix run antiparallel (and they are replicated together), then during replication, one strand will be oriented in the opposite direction (i.e 3’ -> 5’ direction).
Because DNA polymerase requires a primer to begin replication, the leading strand will require one primer, because replication on this strand occurs continuously. On the lagging strand, many primers are required because replication is done piecemeal forming fragments called Okazaki fragments. The fragments are later joined by DNA ligases.
Answer and explanation;
The steps followed in an experiment include;
-Observation; this involves
taking note of something such as a curious phenomenon worth further thought and investigation
-Research; it involves forming a question so as to find out more about the natural phenomenon observed.
-Hypothesis, this is an informed guess as to the possible answer of the question.Its purpose is not to arrive at the perfect answer to the question but to provide a direction to further scientific investigation.
-Experiment, the hypothesis formed must be tested by conducting a well designed and controlled experiment. Its is an important step as it proves whether the hypothesis is correct or wrong.
-Analysis; it entails taking down the results and analyzing it together with the data and suing it to draw conclusion regarding the strength of the hypothesis.
-Conclusion; From the analysis a conclusion about the hypothesis can be drawn, explaining why the phenomenon occurs.
-Publish; the results may then be published as a reference and for future use and comparison.

Explanation:
His appropriate daily calorie intake is approximately 1430 calories daily for weight loss.
his BMI indicates that he is overweight...
BMI or body mass index measures the body the body is fat via a height and weight ratio this index applies can be used for both adults, men and women. BMI categories include underweight- less than 18.5, normal ranging from 18.5 to 24.9; overweight ranging from 25 to 29.9 and obesity with a BMI of 30 or greater. However BMI does have limitations; it often overestimated figures for body fat and athletes and people with more muscular builds and also an under estimation of body fat in older persons on those experiencing muscle loss.
Waist circumference can give can paint a better picture of overall health factors which include high blood pressure, high calorie intake, high blood cholesterol, smoking, blood glucose and physical a lack of physical activity. With two or more of these risk factors coupled with a BMI within the 25 to 29.9 range, persons like John are recommended to lose weight. This may be achieved via calorie restriction, a balanced diet and regular exercise.
For adult males, the recommended intake of calories daily in order to lose up to 1 pound weekly is 2000 calories. 1 pound of fat requires a deficit of 3500 calories weekly. Since his energy needs are up to 1930 calories/day, a maximum deficit of 500 daily or 1430 ingested calories per day should aid in fat loss.
