The virus introduced to the island in 1982 that reduced the wolf population is an example of a density dependent factor.

In ecology, a density-dependent factor, also known as a regulatory factor, is any force that modifies the size of a population of living creatures in response to population density.

Because of their propensity to maintain population densities, density-dependent factors are also known as regulating factors.

Population size and a density-dependent factor's level of control are correlated, therefore an increase in population will increase the influence of the limitation. Density-dependent factors involve biotic factors such as availability of food , predation, competition,  parasitism and disease.

increasing intracellular cAMP leads to smooth muscle relaxation by: Group of answer choices inhibiting IP3 channels, leading to
kirza4 [7]

Answer:

1. Inhibiting IP3 channels, leading to decreased Ca2 in the sarcoplasm and reduced contraction.  

2. Increasing the relative activity of MLCP, leading to a decrease in tension.

3. Activating K channels, increasing K leaking out of the cell which hyperpolarizes it and decreases the likelihood of Ca2 entry.

Explanation

In smooth muscle, cyclic AMP (cAMP) mediates relaxation because cAMP inhibits a specific kinase required for myosin light chain protein (MLCP) phosphorylation, thereby triggering contraction in the smooth muscles. It has been shown that cAMP inhibits 1,4,5-trisphosphate (IP3)-dependent calcium ions (Ca 2+) release by activation of the cGMP-dependent protein kinase (PKG). PKG proteins act to modulate Ca2+ oscillations by stimulating sarcoplasmic Ca2+-ATPase membrane proteins, increasing Ca2+ in the sarcoplasmic reticulum stores and Ca2+ efflux from the cells, and activate voltage-gated potassium (K) channels, thereby leading to membrane hyperpolarization and reducing Ca2+ entry through Ca2+ channels.
