The orange line provides a valuation reference of fair value based on commonly use formulas for valuing a business. The dark blue line represents a calculation of the normal P/E ratio that the market has typically applied to a company over whatever time frame is graphed.

The geographic isolation of islands limits immigration of new species, allowing established species to evolve with few strong competitors and predators. Islands are more prone to invasion by alien species because of the lack of natural competitors and predators that control populations in their native ecosystems.

Interpreting Graphs and Data: Logistic Growth. Part A. What does the right y-axis represent? resources, with quantity decreasing from bottom to top.

Which statement below most accurately describes a phylogenetic tree? A phylogenetic tree is a branching diagram used to illustrate a scientist’s hypothesis about how divergence took place among evolutionary lines.

What this particular tree tells us is that taxon A and taxon B are more closely related to each other than either taxon is to taxon C. The reason is that taxon A and taxon B share a more recent common ancestor than they do with taxon C.

basal taxon: a lineage, displayed using a phylogenetic tree, that evolved early from the root and from which no other branches have diverged. systematics: research into the relationships of organisms; the science of systematic classification.

The Axes. The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).

Birth and death rates in a population. Population size. Predator-prey interactions. Distribution of ages in a population.

Birth and death rates are studied, population size is calculated, and the age distribution is also studied. Demography deals with the overall study of how we, as humans, are spread out in an area, a country, or the world. It also concerns vital statistics such as birth and death rates of a population.

A type I survivorship curve is plotted as a convex curve on a graph. A type III survivorship curve depicts species where few individuals will live to adulthood and die as they get older because the greatest mortality for these individuals is experienced early in life.

Difference between exponential and logistic population growth. Exponential growth = individuals are not limited by food or disease; the population will continue to grow exponentially; not realistic. Logistic growth = the population begins to grow exponentially before reaching a carrying capacity and leveling off.

1: Exponential population growth: When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce.

The world’s human population is growing at an exponential rate. Humans have increased the world’s carrying capacity through migration, agriculture, medical advances, and communication.

Exponential growth may occur in environments where there are few individuals and plentiful resources, but when the number of individuals becomes large enough, resources will be depleted, slowing the growth rate. Eventually, the growth rate will plateau or level off.

Type I or convex curves are characterized by high age-specific survival probability in early and middle life, followed by a rapid decline in survival in later life. They are typical of species that produce few offspring but care for them well, including humans and many other large mammals.

There are three types of survivorship curves. Type I curves depict individuals that have a high probability of surviving to adulthood. Type II curves depict individuals whose chance of survival is independent of age. Type III curves depict individuals that mostly die in the early stages of their life.

Humans and most primates have a Type I survivorship curve. In a Type I curve, organisms tend not to die when they are young or middle-aged but, instead, die when they become elderly.

any age, shown by the Type II survivorship curve, is evident as a straight line with a constant slope that decreases over time toward zero. Certain lizards, perching birds, and rodents exhibit this type of survivorship curve.

A survivorship curve is the graphic representation of the number of individuals in a population that can be expected to survive to any specific age.

Humans and most mammals exhibit a type I survivorship curve. In type II curves, mortality is relatively constant throughout the entire life span, and mortality is equally likely to occur at any point in the life span.

What type of survivorship curve do people in Mexico have? people in Mexico have a type one survivorship curve.
