Research the ecology of your region and find one species that is endangered. Find an estimate of the population of the species in your region.
Describe the threats facing that species, especially threats posed by human activities.

Indicate whether the following statements about the biases in the fossil record are true or false. a) inland species are more likely to be preserved than marine species b) organisms with hard body parts are more likely to be preserved than are those composed soft tissues. c) species that existed over a larger area are more likely to be preserved than species existing over a smaller area. d) organisms that lived very long ago are more likely to be found as fossils than organisms that lived relatively recently e) the fossils of larger organisms are more likely to be found than the fossils of smaller organisms

Competition occurs between species when

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.
