Belinda is a 10-year-old elementary school student who has come in for a physical examination. She is 55 inches tall and weighs 120 pounds. Her doctor calculates her BMI at 27.9 (98th percentile for her age). Concerned about her obesity, Belinda's doctor asks about her diet and her physical activity. Her mother reports that Belinda has become "lazy" and does not like to play outside with her friends after school. She says she is more irritable than usual and complains about helping with household chores. Her mother worries that she may be depressed, although she can think of no family issues that may be responsible for this behavior. Belinda sometimes skips breakfast or has cereal and toast in the morning; she takes chips, a juice drink, and a cheese sandwich made with white bread for lunch; and has a toaster pastry or cookies with milk for a snack after school. She doesn't particularly like meat and frequently asks for buttered pasta with cheese for dinner. Belinda says she eats vegetables "when my mom buys them." A blood test reveals a normal hemoglobin level, low serum iron, moderately elevated transferrin, and low transferrin saturation.
b. He will develop a second experiment to find a way to make the drug successfully lower blood pressure in mice.
c. The data he collected will be used in new investigations to determine why certain people are taller than others.
d. He will use these results to conclude that the drug will most likely lower blood pressure in five percent of people.
Answer:
A on edge
Explanation:
B. An operon is a region of DNA that codes for sugar-metabolizing enzymes.
C. An operon is a region of DNA that codes for a series of functionally related genes under the control of the same promoter.
D. An operon is a region of DNA that consists of a single gene regulated by more than one promoter.
I say b but I’m not sure
Answer: C
An operon is a function portion of a DNA strand that contains a cluster or genes that are controlled under one promoter. This is found in an bacteria or cell and controls protein synthesis. It helps conserve the energy of the cell by only producing proteins when necessary.
B. By increasing the activation energy of the reaction
C. By decreasing the activation energy of the reaction
D. By increasing the energy of the products of the reaction
E. By decreasing the energy of the products of the reaction
Answer:
Enzymes help to carry out biochemical reactions C). By decreasing the activation energy of the reaction
Explanation:
Enzyme catalysis An enzyme catalyzes a biochemical reaction by binding a substrate at the active site. After the reaction has proceeded, the products are released and the enzyme can catalyze further reactions.
