Answer : 1. "Younger people generally have a slower metabolism than adults."
Explanation :
Answer: A) Younger people generally have a slower metabolism than adults. Explanation: Metabolism is the set of life-sustaining chemical transformations within the cells of organisms. The three main purposes of metabolism are the conversion of food/fuel to energy to run cellular processes, the conversion of food/fuel to building blocks for proteins, lipids, nucleic acids, and some carbohydrates, and the elimination of nitrogenous wastes. Younger people have faster metabolism than adults. Hence, the given statement 'Younger people generally have a slower metabolism than adults' is FALSE.

Answer : 2. "Some inherited genetic mutations can be good for the offspring."
Explanation :
Answer: B) Some inherited genetic mutations can be good for the offspring. Explanation: Mutations are accidents in the copying of DNA. A genetic mutation is a random change in the DNA that is passed on further generations of cells and or organisms. Genetic mutations are accidental changes in the DNA in the germ cells or early in the formation of the embryo. These changes if they are in the germ cell will be passed on to other organisms formed by sexual reproduction or asexual reproduction. An example would be the golden delicious apple. A lost of genetic information due to a mutation resulted in a different color of fruit. Genetic mutations that cause diseases are not always passed on to offspring.
