1. zygomycetes reproduce asexually through the haploid spores formed in , or sexually through diploid nuclei formed in .
2. are called club fungi because they produce club-shaped reproductive structures like toadstools.
3. the vegetative body of most fungi is called a(n) , which consists of an interwoven mass of threadlike filaments called .
4. a(n) is a symbiotic association between a fungus and a single-celled alga or cyanobacterium. the fungus protects the photosynthesizer from harsh conditions while consuming the extra nutrients it produces.
5. a(n) is a symbiotic association between a fungus and the roots of a plant. the fungus receives energy-rich sugar molecules produced by the plant while passing minerals and nutrients from the soil to the root.
6. , also known as sac fungi, include morels, yeasts, and the species that produces penicillin.

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?

How does the molecular clock work? a. it analyzes the brain functionality of two different species. b. it examines and compares the physical characteristics of two different species. c. it illustrates relationships between two different species. d. it compares the number of mutations that exist in the dna of two different species.

What evidence supports the law of conservation of energy? a) mechanical energy is converted to chemical energy during photosynthesis. b) oxygen is made from the breakdown of carbon dioxide during photosynthesis. c)energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis. d)the sun gives off light energy that is absorbed by plants.
