Radical Equations 37 minutes This lesson begins by looking at the warm up as a class. I ask for a volunteer to share their steps and solution. I then ask if anyone did the problem in a different way, a useful strategy for highlighting student thinking as well as multiple methods of solution Math Practice 3. I planned the problems carefully to build upon each other both graphically and algebraically.
Amber Parsons Unit 4 Blog 1. Explain the difference between species richness and species evenness. The number of species per sample is a measure of richness. The more species present in a sample, the richer the sample.
Species richness does not take into account the number of individuals of each species present.
It gives as much weight to those species that have very few individuals as to those that have many individuals.
Where as, evenness is a measure of the relative abundance of the different species making up the richness of an area. List and describe four random processes that can cause evolution. One cause of evolution can be random mating, which is when species mate randomly within a population.
Another cause of evolution is no gene flow. Alleles are moved between populations when animals disperse to new locations, and when pollen and seeds are blown by wind or moved by water or animals, which can easily cause evolution. Summarize in your own words allopatric speciation.
That's why a lack of interbreeding means the two populations evolve separately. What factors determine the rate of evolution? The ability of a species to survive depends greatly on how quickly it evolves and the adaptations needed to thrive and reproduce.
Rate of environmental change. Genetic Variation within the species, wide variety of phenotypes increase rate of evolution.
Population size, for instance small populations evolve more quickly. Generation time, species that become reproductively mature at a faster rate tend to evolve more quickly.
Do you agree with the statement below? Why or why not? Yes, because five global mass extinction events have occurred since the evolution of complex life roughly million years ago.
The most commonly known one is dinosaurs, due to the inevitable ending of most species I do think there will be a mass extinction.
In your own words explain the difference between primary and secondary succession in terms of cause and the types of plant species that begin to grow in each. Give an example of each. Primary succession is the colonization of living organisms into an area that was not previously colonized by any living things.
An example of this would be succession after a glacier recedes or after a new island forms from oceanic volcanoes. Secondary succession is the regeneration of the living community after a major disturbance.
For example, after a forest is clear-cut the trees are removed but some small plants, the soil, and soil organisms remain.1: the act of assigning something the assignment of a task 2 a: a position, post, or office to which one is assigned Her assignment was to the embassy in India.
