A mistake in DNA replication before meiosis produces an organism that is better able to outrun predators.
Explanation:
The genetic variation results from the different alleles of a population. The mutation or mistake in DNA replication would cause gene variants which may be beneficial. The variation in the DNA sequence of genome results in variants in small population.
Genetic variation is the cause of natural selection and eventually, evolution takes place with beneficial traits.
It is mentioned in the question that resulting offspring having received the mutant allele could result in better surviving capabilities or phenotypic traits as they are able to outrun predators.
Answer:
The correct answer is - option b) lipids
Explanation:
Lipids are one of the nutrients that are necessary to the body of an individual organism as it plays role in different ways such as energy storage, cell signaling, component of the cell membrane and many more hat maintain homeostasis in organisms body.
These nutrients are made up of fatty acid and glycerol long chains so these are polymer of glycerol and fatty acid and called triglyceride which provides maximum energy in comparison to other nutrients in need.
Thus, the correct answer is - option B) lipids.

The answer to this question would be: decrease, decrease
Anorexia is a mental disease that causes the patient to experience fear of gaining weight. In this case, the patient will try to limit their food intake(in an extreme way) or induce vomit to remove the food.
The effect should be same as starvation or malnutrition. As the food intake decreased, blood glucose is decreased too. The body adapts by lowering the basal metabolic rate so it loses less energy. Insulin and leptin will be decreased too as it was not needed.
We should remember that we should consume all necessary nutrients at a correct amount and proportion. this includes the primary food substance carbohydrates, fat and protein. and protective food substance in a small amount, which includes mineral ions ( iron, calcium etc) and vitamins. Also we have to take in enough water (6-8 cups a day) and fibre to prevent deficient diseases and to maintain health.
in addition, note that the amount of food intake varies with age, sex, body status, daily activity etc. For example, teenagers and pregnant women should increase all necessary nutrients intake to ensure proper growth and development of ourselves or the baby.
