Question

The smaller the divergence in gene sequence, the greater the evolutionary distance between the organisms. True False All of the following are density-dependent factors except nutrient availability rainfall amounts amount of available space predation Which of the following is characteristic of K-selected populations? a high intrinsic rate of increase offspring with good chances of survival small offspring many offspring per reproductive episode A population that Experiences high mortality rates early in life followed by a high survival rate until the end of the normal life span exihibits which type of survivorship curve? Type II Type I Type IV Type III

Explanation / Answer

1. false.

2. rainfall amounts

Explanation:-Density-independent factors, such as weather and climate, exert their influences on population size regardless of the population’s density.

Density-dependent limiting factors include:

•   competition

•   predation

•   parasitism

•   disease

3. offspring with good chances of survival

4. Type III

Explanation:-

Type III Survivorship Curve curve depicts a population with high mortality early in life and high survival later in life (e.g., weeds).
