Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The sympathetic nervous system (SNS) releases the hormones (catecholamines - epinephrine and norepinephrine) to accelerate the heart rate. The parasympathetic nervous system (PNS) releases the hormone acetylcholine to slow the heart rate. Such factors as stress, caffeine, and excitement may temporarily accelerate your heart rate, while meditating or taking slow, deep breaths may help to slow your heart rate.

Think about what the terms density-dependent and density-independent mean. Which of the following statements about how density-d
Lera25 [3.4K]

Answer:

The Correct answer is C: The effect of most density-independent factors on population growth is not related to population density.

Explanation:

In nature, the population size and growth are limited by many factors. Some of these factors depend on the population density, while some others are density-independent.

Limiting density-dependent factors provoke a change in the population growth rate per capita, as the density increases.  In general, this change is a decrease in the growth rate. An example of these density-dependent factors might be competition or limited food availability.

The density-independent factors also affect the growth rate in a population, but they do not depend on its density. Some examples of these are natural disasters, or environmental conditions, among others.  

So,

a) False: the effect of most density-independent factors do not depend on the population density.

b) False: the effect of most density-independent factors do not depend on the population density.

c) TRUE: The effect of density-independent factors are not related to population density

d) False: The effect of most density-dependent factors ARE related to population density
