Barnacles are organisms that live in aquatic environments and live stationary lives attached to hard surfaces. Their feathery ap

pendages catch food as it passes by, making them very successful in tidal waters and within coral reefs. How would scientists best determine the fitness of barnacle populations?
counting the number of surviving offspring a population produces

placing the barnacles in a new environment to determine survival rates of populations

studying the frequency of genes and alleles to determine fitness

counting the number of identical offspring produced by a parent population

The correct option is A.
Fitness refers to the quantitative representation of natural and sexual selection within an evolution. Fitness can be defined in respect to a genotype or a phenotype. Relative fitness is described as the survival or reproductive rate of a genotype or phenotype relative to maximum survival or reproductive rate of other genotypes in the population. Thus, the fitness of a population can be determined by finding out the number of offspring that survive to adulthood.

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.

Anastasy [175]

Answer:

The correct answer is "cell lysis due to the effect of osmotic pressure".

Explanation:

The cell wall is a structure that brings protection from the outside world and also helps to maintain the cell's water balance. The cell wall prevents that the cells is exposed to a large amount of turgor pressure, making the cell turgid when it is under extremal conditions. Some antimicrobials, such as bacitracin, block cell wall synthesis which makes the cell unable to support turgor pressure, resulting in cell lysis due to the effect of osmotic pressure.
