A research assistant has been asked to take microscopic images of a sample from a study. It

was requested that the image must be 3D, but does not require color. It is also important that

the image shows the plasmodesmata, which are small openings or pores on the cell wall that

allow for exchange of molecules such as water.

Which microscope should the research assistant use?

• dissecting microscope

• compound microscope

• scanning electron microscope

• transmission electron microscope

The image below shows an insect called a Walnut Twig Beetle. Without a microscope, you

would not be able to see the hair like structures and texture of the beetle's exoskeleton. Which microscope would have been used to take the image of the beetle?

• dissecting microscope

• compound microscope

• scanning electron microscope

• transmission electron microscope

A hospital purchased a transmission electron microscope. Which sample below would the

hospital view with this microscope?

• a large kidney stone

• the surface of a virus

• a mitochondrion inside the cell

• the movement of a bacterial cell

Use the figures below to answer the question. Figure 1 represents the percentage similarity in

sequences of nucleotides from a homologous gene. Figure 2 represents a cladogram formed

using evolutionary evidence like the information from Figure 1. Baboons have a percentage similar to 97.2% to human genes. Where on the cladogram would

you place the baboons?

• A

• B

• C

• D

The diagram below shows the evolutionary relationship between various species. Which species is most closely related to the sheep?

• dogs

• bats

• deer

• armadillos

The Florida panther was once classified into a separate group within the cougar species. After

further investigation, scientists eliminated the separate group and now classify the Florida

panther and the cougar in the same group. Which of the following would explain why the

classification of the Florida panther changed?

• New genetic evidence suggests a much closer relationship between the Florida panther

  and other cougars.

• Advanced technologies have shown a large difference in cell structure between the

  Florida panther and other cougars.

• Study of their embryos shows major differences in the development of the Florida panther

  fetus when compared to other cougars.

• Shared anatomical features between the Florida panther and cougars were also found in

  newly discovered organisms around the world.

Which of the following statements correctly classifies the organism into the appropriate

Kingdom?

• The organism is classified in the Kingdom Archaea because it has a nucleus.

• The organism is classified into the Kingdom Plantae because it has a cell wall.

• The organism is classified into the Kingdom Bacteria because it has a nucleus.

• The organism is classified into the Kingdom Animalia because it has a cell wall.

Which domain would contain organisms that have membrane bound organelles?

• Archaea

• Bacteria

• Eukarya

• Protista

A student identified four organisms in a sample of pond water and was able to identify

characteristics shown in the table below. Based on the observations of the student, which organism demonstrates the characteristics

of the taxonomic group for bacteria?

• organism 1

• organism 2

• organism 3

• organism 4

A student is having a difficult time comparing and contrasting the characteristics of the

Kingdoms Fungi and Plantae. Which question below would lead the student to discovering a

difference between the two kingdoms?

• Which organisms are eukaryotic?

• Which organisms have a cell wall?

• How does each organism obtain energy?

• How does each organism store its genetic information?
