Answer:

C.) They self-fertilize

Explanation:

Mendel used pea plants because they self fertilized, meaning that the plant could supply a sperm and egg cell so it could produce its own offspring. This makes the process of looking at genetics and traits much easier for the scientist studying the genes of plants.

2. Can the classification system change? If so, provide an example of a way it has changed in the past. (2 points)
Elis [28]

Yes, classification system is still evolving together with our knowledge.

But, before changing the name (e.g. of a species) it is important to collect and gather a wealth of information in order to support that change. Classification system is still evolving. The reasons for the changes are DNA analyzes. It is the new way for discovering relation between organisms and put them in the right context (classification used to be based on morphological characteristics).

Change in classification can be shown in an example of fungi. In the 90s fungi classification included only phyla Chytridiomycota and Zygomycota. Now theyhave been classified mainly on the basis of characteristics of their sexual reproductive structures. So, there are 7 phyla now: Microsporidia, Chytridiomycota, Blastocladiomycota, Neocallimastigomycota, Glomeromycota, Ascomycota, and Basidiomycota

<span>10% rule (efficiency between trophic levels): limits how long an ecosystem's food chain can be
Predator/prey cost benefit analysis (i.e. foraging) -- cost is risk of being eaten or killed along the way, benefit is energy/nourishment obtained: limits distribution of predator v. prey
Immigration/Emigration with other populations and ecosystems
Island biogeography: size of land and distance from another population/ecosystem (mainland): limits population size and variability on island</span>
