Why does exposure to high temperatures cause an enzyme to lose its biological properties?
Ivanshal [37]

Answer:

Shape of active site changes that's why

Enzymes are affected by temperature. So, as temperature increases, enzymes activities also increases, till optimum temperature is reached. If it goes above the optimum temp, the enzymes becomes denatured or can't function anymore due to change in its active site.

A mouse geneticist selected for increased 12-day litter weight (total weight of a litter of offspring 12 days after birth) in a
wlad13 [49]

Answer:

12-day litter weight is a trait that has an important genetic influence and therefore also a high response to selection

Explanation:

Heritability is a statistical measure of how much of the variation in a given trait can be attributed to genetic differences and how much of trait variation is due to environmental factors. A heritability value close to 1 indicates that almost all of the variability is due to genetic factors, while being poorly influenced by environmental factors. In this case, 12-day litter weight is a trait that exhibits an important genetic component (i.e., a high heritability value), thereby the correlation between parent and offspring will be high and lines selected for this trait will show a high response to selection.

Before exploring energy balance and its effect on weight, you must first be able to use the vocabulary effectively.
valkas [14]

Answer:

1. When the number of calories a person consumes is equal to the number of calories he or she burns in a day, that person's body is in Energy Balance.

2. Someone who is in Positive Energy Balance eats more calories in a day than he or she bums.

3. Negative Energy Balance occurs when the number of calories a person bums in a day is greater than the amount he or she consumes.

4. Weight management involves applying strategies that allow someone to keep his or her body weight within a healthy.

5. The Basal metabolic rate is the amount of energy uses in order to perform its basic physiological functions.

6. The Thermic effect of food refers to the number of calories burned in order to digest absorb, metabolze, and store food.

7. The Lean body mass refers to his or her total body - fat mass.

Explanation:

This group of statements are related to body weight, the balance between the energy we consume through food and all the energy we burn through excercise and different activities, such as only mantaining our body temperature and normal processes.
