Loriciferans are microscopic multicellular animals that live in various marine sediments. Before this discovery, some prokaryotes and some unicellular eukaryotes were known to inhabit anaerobic environments. Scientists determined that organisms of the genus Spinoloricus were eukaryotes and not prokaryotes because Spinoloricus cells have –
flagella
herediatry material
cell walls
nuclear membranes
Which of these statements best explains the process of energy conversion that takes place in the mitochondria?
Energy is required for carbon dioxide molecules to form six-carbon sugar molecules
Water molecules and radiant energy are necessary for anaerobic respiration to take place
Oxygen molecules release energy in the form of heat during combustion reactions
The energy in the bonds of glucose molecules is transferred to the phosphate bonds in ATP
A laboratory assistant was told to watch the mitosis of a eukaryotic cell under the microscope and inform the lead scientist when the cell entered metaphase. What should the assistant expect to look for to indicate that the cell is in metaphase?
The chromosomes gather at opposite ends of the cell and uncoil, and then two new nuclear envelopes form around this genetic material.
The sister chromatids separate into individual chromosomes and are moved apart
The chromosomes line up across the center of the cell, and each chromosome is connected to a spindle fiber
The chromatin condenses into chromosomes, the nuclear envelope breaks down, and a spindle begins to form
Which of these must occur during S phase of the cell cycle so that two daughter cells can be produced during M phase?
The DNA must be replicated
The chromosomes must be joined
The cytoplasm must be separated
The cell membrane must be expanded
A photograph of a virus is shown.
The projections on the surface of this virus allow the virus to —
move inside a host cell
attach to a host cell
control a host cell’s DNA
signal other viruses to infect a host cell

The similarities of the bones provide evidence that
the organisms may have evolved from a common ancestor
all species have one kind of bone structure
the cells of the bones contain the same type of mutations
all structural characteristics are the same in animals
According to the classification chart, which two organisms are most closely related?
Organisms 1 and 3
Organisms 2 and 3
Organisms 1 and 4
Organisms 2 and 4
Which characteristics do members of the Kingdoms Eubacteria and Archaebacteria share?
Prokaryotic and multicellular
Eukaryotic and unicellular
Eukaryotic and multicellular
Prokaryotic and unicellular
Five general characteristics of organisms in kingdoms Plantae or Fungi are listed in the box. Which table correctly lists the characteristics of the organisms in the two kingdoms?
The Linnaean taxonomic system classifies organisms into divisions called taxa. If two organisms belong to the same taxonomic group, they are related. Similarity at which of these levels indicates the closest relationship?
Kingdom
Class
Order
Genus

Which stage of mitosis is shown in image E?

anaphase
telophase
Which of the following activities occur in the S phase?
When an area of a chromatid is exchanged with the matching area on a chromatid of its homologous chromosome, _________________ occurs
Crossing over
Mutagenesis
Fertilization
Hybridization
