In addition to loss of muscle mass, inadequate calorie intake can lead to loss of bone density and an increased risk of fatigue, illness, injuries and poor recovery.
<h3>Why is it important to consume adequate calories?</h3>
- When your consumption of calories is not adequate, your body will not get all the necessary nutrients.
- It slows down the metabolism so as to conserve energy
- Calorie restriction can lead to reduce in leptin, a hormone that regulates appetite.
- Lower levels of leptin can lead to increase in hunger thus a person overeats. This results in increase in body weight.
- Low-calorie dieting increases stress and results in the release of the stress hormone (cortisol).
- Due to response to stress, the body conserves energy and the metabolism slows to combat the risk of starvation.
- Therefore, it is important to consume appropriate amount of calories and nutrients.

#SPJ4
Scientists have standardized a concise definition of life. true or falseThe answer is False
Answer:
Chromosome number variation: B. Down syndrome
Loss-of-function allele : D. PKU
Physiological trait
: E. Lactose metabolism
Discovery-based science
: A. Human Genome Project
Genetic cross: C. Model organism
Explanation:
Down syndrome is a condition in which there is an extra copy of the chromosome number 21. Hence, it is a chromosome number variation.
Physiological traits refers to any function of a body. Hence, it matches with lactose metabolism.
Human Genome Project was a project under which the whole genome of the humans were sequenced. Hence, it is a discovery based science.
A genetic cross is made between model organisms to test for the offsprings that would be produced from a cross. Hence, genetic cross and model organism math with each other.
