Wildlife biologists are attempting to monitor the population size of the insect pest known as the gypsy moth (lymantria dispar) during the summer months. to estimate the total population size of these insects living in a 50 square kilometer forest, biologists have sampled 10 random trees, counting the number of eggs and larvae on each selected tree. which factor should be modified to improve the overall experimental design? a) the sample size should be increased. b) data should be collected all year long. c) weather conditions should be controlled. d) researchers should include other insect species.

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
