Gender, age and body weight are the three factors.

<h3>What are the effects of gender, age and body weight on energy expenditure?</h3>

Body weight:

Energy consumption while at rest is determined by body size and weight. Due to the higher maintenance costs associated with a larger body, a heavier person has a higher resting energy requirement. The most unpredictable part of overall energy expenditure is activity-induced energy expenditure. Since larger subjects' activity energy expenditure is not higher in proportion to the expense of moving with a higher body weight, smaller and leaner subjects often move more. As a result of changes in body size and body composition, eating causes variations in energy expenditure.

Gender:

In comparison to girls of the same size and age, adult males frequently have 10–20 percent more muscle mass. Because muscle burns more calories than fat, men have greater basal metabolic rates (BMR). As a result, men need 5–10% more energy than women.

Age:

Compared to adults, children and adolescents require more energy for growth and development. As people age, their body composition changes and their energy needs decrease, resulting in a decrease in BMR. As people age, many of them become less active.

The human population has changed since it first appeared on earth as The b. population has generally increased, and at rates that have varied over time.

Humans, as well as other populations, have changed since their appearance on earth. Some populations became extinct as they were not able to cope with the environmental changes whereas other became more adaptable and increased in number over time.

The human population has also increased with the passage of time. However, the increase in the rate of the human population was not a stable one. At some times in the past, the population number declined due to environmental factors such as the eruption of a disease etc.

However, with the passage of time, humans have managed to adapt themselves to the changing environmental conditions and their population is increasing rapidly.

Although a part of your question is missing, you might be referring to this question:

The human population has changed in ways that are similar to other populations. How has the human population changed since it first appeared on earth?

a. The population has generally increased at a relatively constant rate

b. the population has generally increased, and at rates that have varied over time

c. The population increases rapidly until it reaches carrying capacity, where it has remained for thousands of years

d. The population increases rapidly until it reaches carrying capacity, and then decreased at a constant rate

Answer:

b

Explanation:

environmental factors play a very important role in the development of an individual
