Hypothesis
Before doing an experiment a scientist writes the following statement, "If water is present, then the growth of mold on bread may accelerate". This is an example of a(n)
Thickness of fur
Dr. Thalamus wanted to know if a new hormone would increase the thickness of fur on rabbits. Twenty rabbits of the same type and age were placed into two groups. Group A was given the hormone every week. Group B was not given the hormone. What would be the dependent variable?
Hormone
Dr. Thalamus wanted to know if a new hormone would increase the thickness of fur on rabbits. Twenty rabbits of the same type and age were placed into two groups. Group A was given the hormone every week. Group B was not given the hormone. What would be the independent variable?
was fed the same amount without the food additive
A biologist wants to test the effectiveness of a new food additive on causing growth in mice. An effective control group would be on that
Proteins
Nucleotides are to nucleic acids as amino acids are to
Lipids
Which of the following macromolecules is used for long term energy storage?
The peanut oil used to fry the fries.
Which of the following parts of a Chick-Fil-A meal is an example of a lipid?
Carbohydrates
Which of the following organic compounds is the short term source of energy for living things?
contain genetic material
Which of the following characteristics is common to both bacteria and viruses?
Viruses can reproduce only using a host cell.
How do viruses reproduce?
the ability to nourish
In order to be classified as living, an organism must have among other characteristics
regulates what enters and exits the cell
Which is a function of the cell membrane?
activation energy
What is the term used to describe the energy needed to get a reaction started?
catalysts used in all chemical reactions
What are enzymes?
Nucleus
Which cell structure contains the cell's genetic material and controls the cell's activities?
Lysosomes
Which organelle is the recycling center that breaks down worn cell parts using digestive enzymes?
Golgi apparatus
What cell part is labeled by the arrow in the image below, which helps package substances?
Ribosomes
Which organelle is the site of protein synthesis?
Cell Walls
Structures that support and give shape to plant cells are
prokaryotic cells lack a true nucleus and membrane bound organelles
Prokaryotic cells differ from eukaryotic cells in that
cell wall and chloroplast
What two structures are found in plant cells that are not found in animal cells?
mitochondria
Which organelle converts food into energy?
Homeostasis
Sweating is a process by which excess water and salts and a small amount of urea are removed from the human body. Sweating involves the skin and the excretory system. This ability of an organism to maintain a stable internal environment is called
stores food, water, waste, etc.
What is the function of the cell part that is labeled by the arrow in the image below?
Semi-permeable
The type of membrane that allows only certain molecules to pass through is
passive transport
The movement of substances into and out of the cell without the use of energy is called
osmosis
The movement of water across a semi-permeable membrane from an area of high water concentration to an area of low water concentration is called
Hypotonic
If the solution surrounding a cell has a lower concentration of solutes than inside the cell, water will move into the cell through osmosis, causing it to expand. What kind of solution is surrounding the cell?
an area of high concentration to an area of low concentration
Diffusion is the movement of molecules from
the organism will shrink
Organism Y has an internal salt concetration of 3 g/L. Solution A has a salt concentration of 5 g/L. What will most likely happen to the organism if it is placed in solution A?
water to move into the cell
An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes
an Amoeba wraps its' membrane around a small unicellular organism to eat it
Which of the following is an example of phagocytosis?
active transport
Potassium molecules move from areas of LOW concentration to HIGH concentration through a protein channel in the cell membrane. This would be an example of
swell, but stop when the cell wall prevents further expansion
If a plant cell is placed in distilled water, it will
Isotonic
A red blood cell has been placed in a solution. There is no net movement of water. This means that the solution is
Exocytosis
When vesicles are used to release waste product out of the cell, it is called?
ATP
The chemical energy supply for all living cells s contained in a molecule that, when broken down, releases the energy so that it may be used for activities such as muscle contractions, photosynthesis, and locomotion. This molecule that is a storehouse of energy is
Chloroplast
Which plant organelle is the site of photosynthesis?
False; only plants do photosynthesis
Plant and animal cells both perform respiration and photosynthesis.
is where cellular respiration occurs
The mitochondrion of a cell
38
During aerobic respiration, how many ATPs are produced from one glucose molecule?
mitochondria
The Krebs Cycle and the Electron Transport Chain phases of cellular respiration take place in which organelle?
Autotrophs
Organisms, such a plants, that make their own food are called
a bond is broken between the second and third phosphate group
Energy is released from ATP when
in the thylakoid
Chlorophyll is needed for the light dependent reactions, so it is found in what part of the chloroplast?
glycolysis --> krebs cycle --> electron transport chain
Which of the following is the correct sequence of events in cellular respiration?

Lactic acid fermentation occurs in
photosynthesis
The equation below summarizes what biological process?
6CO2 + 6H2O à C6H12O6 + 6O2

Cellular respiration is called an aerobic process because it requires
