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.

What is a group of organisms that are closely related and share similar characteristics

This is the process of making a prediction based on the results of prior observations of similar events.

Cladistics is a way of classifying organisms by examining the characteristics of their ancestors and descendants and depicting the relationships in a cladogram. which of the following best describes a challenge in classifying organisms this way? a. there are millions of species on earth, and a cladogram is not a practical means for classifying all of them. b. it is impossible to tell which organisms are most closely related to each other using a cladogram. c. cladograms are detail-oriented and do not provide a useful understanding of evolutionary relationships. d. there is a limited number of ways to organize the information, so most cladograms end up looking very similar.
