A student produces a labeled drawing of a virus for a presentation. The student states that the capsid has a function similar to the nuclear membrane found in animal cells.
Both transport proteins throughout the structures.
Both provide energy for activities in the structures.
Both protect genetic information for the structures.
Both code for the proteins needed for reproduction of the structures.
A type of cellular transport is shown.
Active transport, because energy is being used to move molecules against the concentration gradient
Facilitated diffusion, because energy is being used to move molecules with the concentration gradient
Osmosis, because energy is not being used to move molecules with the concentration gradient
Endocytosis, because energy is not being used to move molecules against the concentration gradient
The diagram shows molecules that a mitochondrion uses and produces during a cellular process.
DNA
RNA
CHO
ATP
Which table shows two steps of DNA replications?
The karyotype, or chromosomal profile, for humans is shown. A karyotype can be used to investigate genetic disorders.
The cell cycle skips G0 phase and repeats G1 phase.
Mitotic division is skipped, and the cell cycle proceeds to cytokinesis.
Mitotic division stops in metaphase and cannot proceed to anaphase.
The cell cycle skips S phase and proceeds to G2 phase.
In a study of physical endurance, researchers observed significant increases in the heart rates and breathing rates of participants immediately after they engaged in strenuous exercise.
Which statement best explains the increase in the heart rate and the breathing rate during exercise?
The water concentration in the blood increases.
Body cells require increased oxygen as energy is expended.
Muscle cells increase in temperature and require fluid to reduce the temperature.
An increase in muscle activity causes increases in glucose levels in red blood cells.
In 1898 Friedrich Loeffler and Paul Frosch found evidence that the cause of the highly contagious hoof-and-mouth disease in livestock was a microscopic infectious particle. It was discovered that this particle requires a host cell to reproduce.
Which pathogen is most likely responsible for causing hoof-and-mouth disease in livestock?
A bacterium, because it is contagious
A fungus, because it infects livestock
A protist, because it is microscopic
A virus, because it requires a host cell to reproduce
Which of the following activities occur in the S phase?
Prophase
Anaphase
Telophase
Interphase

Which of the following activities occur in the S phase?
Which is represented by Structure X?
Which of the following activities occur in the S phase?
Which of the following activities occur in the G1 phase?
The flu is caused by a virus.
The ability to maintain a stable internal environment is called ________________.
Metabolism
Mitosis
Heterozygous
Homeostasis
Cell have several mechanisms for regulating their internal environments. Which of these mechanisms involved in maintaining homeostasis requires energy?
osmosis
diffusion
active transport
passive transport
Mature human muscle cells and nerve cells
remain undifferentiated unless an injury occurs
become cancerous more easily
continue to divide throughout their life
are permanently in a state of non-division
The cell cycle control system
receives messages from the outside of the cell that influence cell division
triggers and controls major events in the cell cycle
is influenced by growth factors that bind to cell receptors
all of the above
Diffusion, a form of passive transport, is the movement of
particles from high to low concentration
particles from low to high concentration
