Which of the following are the best recommendations for improving the methods of an experiment to test how different beverages affect baby tooth loss?
Try using multiple independent variables in your experiment.
Try focusing efforts on a single trial.
Try using different brands of soda as well as different beverages.
Try adding a control group to your experiment.
Dante uses 12 of his saved baby teeth and soaks them in different beverages for 36 hours. After the time, he measures the mass. Based on his findings in the above table, which statement is true?
Milk had the greatest loss in tooth mass.
Diet cola had the greatest loss in tooth mass.
Cola had the least loss in tooth mass.
Fruit punch had the least loss in tooth mass.
What is science?
Study of the supernatural
Lists of beliefs and facts
Finding evidence to support something you already think
Collecting and organizing data about the natural world.
Which of the following best describes a result of the polar nature of water molecules?
Ionic compounds dissolve easily in water
The volume of water decreases by nearly half when it is frozen.
Water molecules repel each other
Water molecules repel most other substances.
Water has a much higher specific heat than most other covalent compounds. What do you predict might happen if water had a low specific heat instead?
Flooding would occur and animals would be forced to migrate.
Harmful organisms living in water would reproduce at a rapid rate.
Organisms that are sensitive to changes in temperature would die.
Plants would not have enough water in effectively carry out photosynthesis.
Water molecules have properties that enable the to stick to each other and to the inner surface of the xylem. As a result, the water can move through the plant by capillary action. Which property of water is most direct cause of capillary action within the xylem?
Water is a versatile solvent
Water is a polar molecule
water has a high specific heat capacity
Water has a high surface tension
Which of these possible replies best describes scientific principles or the work of scientists?
Scientific theories do not become scientific laws
Science always finds the right answer
One should be wary of science because it is based on research and evidence, not bias and opinion.
Scientists take each other at their word regarding experimental results, and the public should, too.
Which statements are true about theories in general
Theories may become scientific law.
Theories are broad and useful explanations for how the world works.
Theories are accepted as absolute truth in the scientific community.
Theories are dynamic and complex, but not constantly subject to revision.
Which of the following statements is part of the cell theory?
Cells are composed mostly of empty space.
Cells are generally large enough for the unaided eye to see.
All cells are produced from existing cells.
Only animals are made up of cells.
Which of the following is NOT one of the three parts of Cell Theory?
All living things are made of cells.
The cell is the smallest living thing that can perform all the functions of life.
Cells are too small to see without a microscope.
All cells must come from pre-existing cells.
Megan says "I don't believe what the scientists say, because that's just a theory," her brother replies. "If those scientists were certain, then it would be a law, not just a theory." Which statement explains why they are having a misunderstanding?
Her brother has a misconception that theories become laws and is confusing the scientific use of theory with the everyday use of the word.
Her brother is confusing the meanings of scientific law and scientific theory.
Her brother has a misconception about the types of questions that science can answer and which are addressed by the other ways of knowing.
Her brother is confusing the meanings of the terms theory and hypothesis.
Jellyfish have body surfaces that are permeable to water but not to salt. Fortunately, the ocean is very stable in its salt content with an average salinity (salt content) of 35 ppt (parts per thousand). What would happen if a jelly fish were placed in a low salinity environment such as an estuary with a salinity of 10 ppt?
The jellyfish would lose salt into the estuary.
The jellyfish would lose water into the estuary.
The jellyfish would gain salt from the estuary.
The jellyfish would gain water from the estuary.
A red blood cell is 90% water. A red blood cell is suspended in 11% water solution. What will likely happen to the red blood cell?
The cell will burst
The cell will shrink
The cell will not be affected
The cell will continually grow then shrink.
According to the diagram, which of the following is correct about how the solutes are moving across the membrane?
active transport is occurring because solutes are moving from low concentration to high concentration.
Bulk transport is occurring because solutes are moving from high concentration to low concentration.
osmosis is occurring because water is moving from high concentration to low concentration.
Diffusion is occurring because solutes are diffusing from high to low concentration.
Which of the cells displayed in the chart below can be characterized as a prokaryotic cell?
Cell A
Cell B
Cell C
Cell D
Which of the following characteristics defines a cell as a eukaryote?
Being able to move
Being able to reproduce
Having a nucleus
Having ribosomes
Which of the following best compares the structures found in plant cells and animal cells?
Animal cells contain cell walls and a large vacuole while plant cells contain cell membrane and many small vacuoles.
Animal cells do not contain chloroplasts, cell walls, or a large vacuole while plant cells do.
Plant cells contain rough endoplasmic reticulum and a golgi apparatus while animal cells contain smooth endoplasmic reticulum surrounded by lysosomes
Plant cells have rigid cell walls and do not contain mitochondria or ribosomes while animal cells do.
Which of the following best compares the membranes found in different types of cells?
Animal cells have cell membranes and cell walls, but plant cells do not have cell membranes.
Animal cells have membrane-bound organelles, while plant cells carry out the functions necessary for life in the cytoplasm.
Prokaryotes have only cell membranes, while eukaryotes have both cell walls and cell membranes.
Prokaryotes and eukaryotes have cell membranes, but eukaryotes also have membrane-bound organelles.
The following diagrams show an animal cell dividing during four stages of the cell cycle. Place the stages in order.
A, B, C, D
B, D, A, C
B, A, D, C
C, D, A, B
Most chemotherapy agents kill cancer cells by affecting the S-phase of the cell cycle. Based on the diagram above and your knowledge of the cell cycle, which of the following best explains why the S-phase is targeted by chemotherapy agents?
Because the cell grows and is most active during the S-phase.
Because the cell divides and creates new cells during the S-phase
Because the cell duplicates its DNA for its daughter cells during the S-phase
Because the S-phase lasts the longest amount of time of all the cell cycle phase.
