binding organs and tissues together
control and coordination
movement
protection
The data in the graph are the result of a paramecium being placed in a hypertonic salt solution.
Based on the data in the graph, which would most likely happen if the paramecium were placed in distilled water?
The contractions would increase.
The contractions would decrease.
The contractions would cease altogether.
The contractions would establish dynamic equilibrium
A sample of tissue has been observed to be tightly packed and regenerative. What type of tissue is the sample?
epithelial
connective
nervous
muscle
Which organelles are labeled D? and what is one feature that distinguishes them from the other labeled organelles?
chloroplasts; the only organelles that produce sugars from sunlight
ribosomes; only found in animal and bacterial cells
centrioles; found in animal cells but not plant cells
mitochondria; the only energy-generating structures found in cells

Golgi apparatus
lysosome
ribosome
endoplasmic reticulum

A patient with osteoporosis (reduced bone mass) may have a history of health issues. One issue could be
not enough skin exposure to the sun to make Vitamin D.
weak ligaments.
an increase in the absorption of calcium in the digestive system
weak tendons.
Which best defines homeostasis?
modifying the external environment
maintaining a stable internal environment
controlling what enters and exits the cell
movement of materials into the cell
How would the contractile vacuole of a freshwater amoeba respond if the organism was placed in seawater?
with more contractions
with fewer contractions
the contractions would suddenly cease
with the same frequency of contractions
The data in the table were recorded during an investigation in which a paramecium was placed in a hypertonic salt solution.
Which statement correctly describes the bars on a bar graph representing the data?
The graph has five bars of equal height.
The bars range from tallest for very high concentration to shortest for very low concentration.
The bar for very low concentration is twice the height of the bar for medium concentration.
The bar for very high concentration is five times the height of the bar for very low concentration.

nucleus
endoplasmic reticulum
mitochondrion
Which organelle makes the proteins that are needed by the cell?

Which structure is found in the cytoplasm of a prokaryotic cell, but is not found in the cytoplasm of a eukaryotic cell?
DNA
ribosomes
nucleus
mitochondria
A scientist discovers a cell that has chloroplasts, cytoplasm, DNA, and a cell membrane. Which statement best describes how the cell could be classified?
The cell is prokaryotic because it has DNA.
The cell is prokaryotic because it has cytoplasm.
The cell is eukaryotic because it has a cell membrane.
The cell is eukaryotic because it has chloroplasts.
The endosymbiotic theory provides an explanation for the origin of chloroplasts. Which trait of chloroplasts supports this explanation?
Chloroplasts do not reproduce.
Chloroplasts rely on proteins that are made by the cell.
Chloroplasts are larger than prokaryotic cells.
Chloroplasts have their own DNA.
Consider the plant cells in the image below.
Which is a function of the cell structure that is labeled X?
It stores lipids.
It helps in cell metabolism.
It provides support.
It transports proteins.
A magnifying glass is an example of which type of microscope?
electron microscope
scanning microscope
compound light microscope
simple microscope
Which statement is one component of the cell theory?
All living and nonliving things consist of one or more cells.
Cells and living organisms are spontaneously created.
Cells are the most complex unit of structure and function in living things.
A cell is the basic unit of structure and function of all organisms
Who first recognized the cell as the universal unit of life?
Virchow
van Leeuwenhoek
Hooke
Schleiden and Schwann
Which best describes the cell theory?
Scientists know all there is to know about cells, so the cell theory will not change.
As technological advancements are made, the cell theory may change.
A theory, once formulated, cannot be changed.
The development of a synthetic cell has caused the cell theory to change.
