Invasive species have a higher reproductive potential than native species. b. invasive species are keystone species. c. invasive species are not held in check by the predators and agents of disease that have always been in place for native species. d. invasive species come from geographically isolated regions, so when they are introduced to regions where there is more competition, they thrive. e. invasive species are less efficient than native species in competing for the limited resources of the environment.

The many volcanoes located along the edge of the pacific ocean make up the ring of fire. how does subduction play a role in the volcanic activity in the ring of fire?

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?

All individuals have two alleles for a given trait. according to mendel's these alleles are passed down one each from both mother and father.
