Question 1
What is the term for the cell's ability to maintain a stable internal balance?
a
peristalsis
b
metabolism
c
physiology
d
homeostasis
Question 2
How do ribosomes and the Golgi apparatus interact to maintain homeostasis?
a
Ribosomes store liquids and other waste products that are created by the Golgi apparatus.
b
Ribosomes synthesize proteins that are sorted and packaged by the Golgi apparatus.
c
Ribosomes transport proteins and enzymes that are synthesized by the Golgi apparatus.
d
Ribosomes store molecules that are converted into usable energy by the Golgi apparatus.
Question 3
Summarize the lytic cycle.
10.7A: The Lytic Life Cycle of Bacteriophages - Biology LibreTexts
a
The viral DNA incorporates itself with the host cell’s and replicates whenever the host cell replicates itself.
b
A virus injects its genetic material into the host cell, copies itself using the host's structures and resources, and then forms new viruses that burst out of the host cell.
c
A virus copies its own genetic material and then splits its cell membranes in half to form two identical viruses.
d
A virus lays eggs on the host cell’s protein coat, which then hatch and move on to infect other cells.
Question 4
A single-celled organism is represented in the diagram shown below. An activity is indicated by the arrow.
Which substance is the main energy source needed to perform this process?
a
Photosynthesis
b
ATP
c
DNA
d
Enzyme
Question 5
The picture shows a leaf found on an autotrophic plant.
The cells in this leaf are making their own energy by the process of
a
respiration, where oxygen and sunlight at Q and R are taken in and then converted into carbon dioxide and glucose at S and T.
b
photosynthesis, where glucose and oxygen at Q and R are taken in and then converted into water vapor and thermal energy at S and T.
c
respiration, where carbon dioxide and oxygen at Q and R are taken in and then converted into thermal energy and methane gas at S and T.
d
photosynthesis, where carbon dioxide and sunlight at Q and R are taken in and then converted into glucose and oxygen at S and T.
Question 6
A student sets up an investigation by placing a plastic bag over a plant. She secures the plastic bag so that it is completely sealed and nothing can enter. She observes the plant daily to see if it remains green and healthy.
Which TWO questions is this investigation, as described, designed to answer?
a
Can the plant perform respiration without a large supply of carbon dioxide?
b
Can the plant perform photosynthesis without a large supply of oxygen?
c
Can the plant perform respiration faster than a plant that is not sealed?
d
Can the plant perform respiration without a large supply of oxygen?
e
Can the plant perform photosynthesis faster than a plant that is not sealed?
f
Can the plant perform photosynthesis without a large supply of carbon dioxide?
Question 7
A substance that moves across a cell membrane without using the cell’s energy tends to move___________.
a
away from the area where it is more concentrated
b
toward the area where it is more concentrated
c
away from the area of equilibrium
d
away from the area where it is less concentrated
Question 8
Under what condition will diffusion take place most rapidly?
a
movement through a permanent barrier
b
movement from an area of high concentration to an area of low concentration
c
movement against a concentration gradient
d
movement from an area of low concentration to high concentration
