Exponential growth Study guides, Revision notes & Summaries

Demographics Answer the study of the dynamics of population change Exponential curve- Answer when populations follow an accelerating rate of growth which is proportional to the population size Crude Birth Rate (CBR) Answer number of births per thousand individuals in a population per year Crude Death Rate (CDR) Answer number of deaths per thousand individuals in a population per year calculate CDR and CBR Answer dividing the amount of deaths or births by the population, and then mult...

How did the initial conditions of development differ between developed and developing countries? correct answer: 1. Developing countries are often less well endowed with natural and human capital than the currently developed nations. 2. Low-income countries have on average lower levels of real per capita income than developed countries in the world. 3. By the time of their early industrialization, many developed countries, notably the United Kingdom, the United States, and Canada, had economi...

KSU Biology 198 Exam 2 with Certified Solutions Ecology The study of interactions between life forms and their environment. Ecosystem All living organisms in an environment plus the physical and chemical environments in which they live. GPP (Gross Primary Productivity) All the sunlight that hits a given area, primary producers use it to grow and reproduce, then converted to NPP NPP The usable energy left over for consumers is called ____. It helps determine how many trophic lev...

evolution - change in gene frequency in a population over time mechanism - a way for change to occur natural selection - a process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits - proposed mechanism for evolutionary change variation is determined by - the environment heredity - passing of traits from parents to offspring reproductive success - successfully passing genes to next generation...

Binary Fission : Most common form of bacterial reproduction Binary Fission 4Basic Steps : 1.Growth of cell size and increase in cell components 2.Replication of DNA 3.Division of the cytoplasm (cytokinesis) 4.Septum formation and division of daughter cells Z ring Assembly : •Cytokinesis is directed by FtsZ protein •FtsZ assembles Z ring to form divisome •Divisome activates production of peptidoglycan and septum Generation Time : •Generation Time (Doubling Time) - time takes ...

autotroph - organism that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer biosphere - part of Earth in which life exists including land, water, and air or atmosphere community - assemblage of different populations that live together in a defined area consumer - organism that relies on other organisms for its energy and food supply; also called a heterotroph ecology - scientific study of interactions among org...

Density Dependent Factor - A factor that influences an individuals probability of survival and reproduction in a manner that depends on the size of the population (i.e. predation, disease, food supply) Density Independent Factor - A factor that has the same effect on a individual's probability of survival and reproduction at any populations size (i.e. hurricanes, floods, fires) exponential growth models - occurs when populations are not limited by resources. (J-curve) logistic growth mo...
