For a specimen of an active motile microorganism, the most effective microscope for visualization would be the phase contrast microscope.

In summary, the phase contrast microscope would be the most effective microscope to use when a live microbe specimen is in question due to the fact that it would use a phase change to create an enhanced image without having to kill or stain the microbe.

In snapdragons, tallness (T) is dominant to dwarfness(t), while red color is due to gene (R) and white to its corresponding allele (r). The heterozygous condition results in pink (Rr) flower color.

The process of transcription is known to have a less effective “proofing” stage to check the sequence of bases than does the process of DNA replication. What effect does this have on the base sequences produced by transcription?

A.Errors in the base sequences will result in a damaged strand of DNA.

B.The base sequences of mRNA can be exactly the same as those on DNA.


C. It is more likely that there will be more errors in coding base sequences in mRNA than there will be in DNA.

D. It is more likely that there will be fewer errors in coding base sequences in mRNA than there will be in DNA.

How do icebergs contribute to rising sea levels?
○ They melt and increase the amount of water in the ocean.
○When they increase in size, they take
water out of the ocean.
○They break away from land, displacing significant amounts of water.
○The number of icebergs has been increasing, taking up more space in the ocean​

Ecologists are interested in quantifying different kinds of biodiversity. In each of the two studies outlined here, which kind of biodiversity are ecologists studying?

a. Ecologists draw blood samples from basking shark (Cetorhinus maximus) specimens caught from a single large population in the Atlantic Ocean. From each blood sample, the ecologists isolate DNA. Comparing several DNA sequences across the individuals that were sampled, the ecologists are able to estimate the variation in DNA sequences in the entire population.

b. Ecologists establish 20 small areas, called plots, randomly scattered across a California grassland. They count the number of different plant species present in each plot. By noting how many species appear in the plots, the ecologists are able to estimate the number of species in the entire grassland.

In the year 2374, humans finally developed the technology necessary for time travel. You are a scientist interested in the population genetics of extinct animals. After seeing Jurassic World, you decide to go back in time to study a population of velociraptors. The skin color of this dinosaur varies between tan (dominant) and brown (recessive). You observed 336 tan velociraptors and 64 brown velociraptors during your study. Assume the population is in Hardy-Weinberg equilibrium. a) What is the allelic frequency of the dominant (tan) allele in the population

The two genes f and g, code for body size and aggressiveness, respectively. The F allele is dominant over f, and codes for a larger body size. The G allele is dominant over g, and codes for more aggressive ants. You perform a Mendelian dihybrid cross (NOT a test cross) on these traits. If there is no recombination between these genes (recombination frequency = 0.00), what ratio should you see phenotypes in in the offspring? (note that the parent generation was made up of large aggressive ants and small docile ants.)
A. 9 large aggressive:3 large docile:3 small aggressive: 1 small docile
B. 1 large aggressive:1large docile:1small aggressive:1small docile
C. 12 large aggressive:4 small docile (i.e. 3 large aggressive:1small docile)
D. None of the above
