Proteins contain 4 calories in every gram, while fats contains 9 calories for every gram, carbohydrates carbohydrates contain 4 calories in each gram. Therefore, 15 grams of carbohydrates contain 15 ×4 = 60 calories, 8 grams of fat will have 8×9= 72 calories and 8 grams of proteins contain 8×4= 32 calories. Hence, the total number of calories will be 60+32+72 = 164 calories
Answer:
More energy
Explanation:
More energy is needed to carry out the metabolic rate of a person ( the minimum amount of energy required to carry out all of the reactions needed to keep a person alive).

Nondisjunction is most likely responsible for the failure of a gamete to receive a copy of a particular chromosome.
What is non-disjunction?
When a pair of homologous chromosomes fails to segregate or separate at anaphase, both of the pair's chromosomes pass to the same daughter cell. This most likely happens during meiosis, but it can also happen during mitosis to create a mosaic individual. These are some potential causes of nondisjunction, while the exact cause or causes are unknown. Growing maternal age is linked to trisomy 21 and trisomy 18 fetuses and newborns, indicating that the mother's age may be a significant etiological component. Chromosomal structural defects such translocations and pericentric inversions might hinder chromosome pairing during meiosis and encourage nondisjunction.

The scientific design in which has limitations
due to oversimplification is the statement “in a study of the effect of lawn
fertilizer on the health of a backyard pond, biologists grow two colonies of
duckweed in a large flask to represent pond ecosystems”. Oversimplification is
an overview and generalization of a statement to miscomprehension,
misperception or even error. It overlaps the true statement.
