In 2001, a small population of mice in Colorado had 150 births, 110 deaths, 12 immigrants to the population, and 2 emigrants from the population. In 2002, Colorado experienced a severe drought. In this year, the birthrate for the population remained the same (150), but there
were 140 deaths, 2 immigrants to the population, and 12 emigrants from the population. Keeping in mind the equation for growth rate (r= [B
+ 1 - [D+]), explain what the population curve would look like for this population during the period from 2001 to 2002.

It would be a U-shaped curve because the population dropped and rebounded during these years.

It would be flat because the population experienced neither growth nor decline during these years.

It would show an increase in the population in 2001 and a flat line in 2002.

It would show an increase in the population in 2001 and a decrease in the population in 2002

The collared lizard is a species found in the desert southwest. male collared lizards show considerable color variation, ranging from brightly colored to a very dull pattern. your goal is to determine the function, if any, of male color patterns in collared lizards, using the scientific method. your tentative explanation is that male color plays a role in attracting females for mating purposes. you predict that females will preferentially choose brightly colored males over dull-colored ones. to test this prediction, you observed the interactions of female collared lizards with their male counterparts. you selected males that were the same age and size, and that differed only in their coloration pattern. you placed equal numbers of the two types of male lizards, bright and dull, in aquariums, along with one female lizard per aquarium. out of 350 aquariums observed, the female chose to mate with the brightly colored male 277 times, and the dull-colored male 70 times. in 3 instances, the females did not mate with either type. create a bar graph of your data, plotting the type of male (dull or brightly colored) on the x-axis. on the y-axis, plot the frequency with which each type of male was chosen by females. using this graph, answer the following question(s). is it reasonable to conclude (i. e., is it supported by the data) that female collared lizards prefer more brightly colored male lizards over dull-colored males?

The phylogenetic tree illustrates the relationship between humans and our closest living relatives. the tree was based on biochemical comparisons, including dna and amino acid sequences. according to the biomolecular data, we could infer that a) the four organisms do not have a common ancestor. b) humans are more closely related to chimps than any other apes. c) chimps are more closely related to gorillas than they are to humans. eliminate d) there is no evidence if any relationship between the four branches on the tree.

The pressurized plants and fungi mentioned in the video have some surprising similarities. what differences would you expect them to have?
