| Mitochondria are bounded by a double membrane. The inner filled space is called the matrix which contains _______ that break down carbohydrate products, releasing _________ to be used for ATP production | enzymes/energy |
| Mendel carried out monohybrid crosses with his peas. What does that mean? | He was only looking at a single trait at a time in each experiment |
| Which of the following is mismatched? A. Cilia-microtubules B. Centrioles-Spindle C. Mitochondria-stroma D. Lysosomes-hydrolytic enzymes E. Ribosomes-RNA | B. Centrioles-Spindle |
| Which is not a correct association of cell organelles and structure? | Endoplasmic reticulum- concentrated chromatin, RNA and nucleoli |
| Cellular respiration is best asociated with the | Mitochondrian |
| The final shape of a protein is very important to its function. When proteins undergo an irreversible change in shape called __________ they ____________ perform their usual functions | Denaturation / cannot |
| Technology is the __________ | application of scientific knowledge for a practical purpose |
| Which statement is false concerning movement of molecules across the cell membrane? | Lipid molecules do not pass through easily |
| Tissues that produce large amounts of secretions, such as the gastric glands of the stomach, contain cells with large numbers of | golgi apparati |
| A membrane sac filled with large molecules of potassium is suspended in a beaker of water. What will happen? | Water will enter the sac and it will swell |
| Which sequence of classification categories is in the proper order from least to most inclusive? | species, gnus, family, class, order, phylum, kingdom, domain |
| The layer where organisms can exist on the surface of the earth is the | biosphere |
| A cell placed in a hypotonic solution will | gain water |
| Nutrient molcules are used as building blocked or for energy. This best represents which characteristic of life? | Living things acquire materials and energy from the environment |
| A student sitting on the back row oped a bottle of foul-smelling perfume and dabbed it on her wrists. One-by-one (beginning from the back of the room) the students began to cough due to the foul smell. This phenomena was due to | diffusion |
| Both plans and animal cells have mitochondria because they both | Need ATP for energy |
| The structure shown in the following figure is H-H-N-C-R-H-C--OH--O | an amino acid |
| During photosynthesis, solar energy is converted to chemical energy by the chloroplasts. The process is represented by: | solar energy+carbon dioxide+water > carbohydrate+oxygen |

| Osmosis can occur when a membrane is | semipermeable |
| Cellular respiration is best associated with the | mitochondrian |
| You are conducting an experiment to determine what concentration of disinfectant is most effective in killing bacteria. In this example, the concentration of disinfectant would represent the | experimental variable |
| Which of the following types of lipid is the most abundant constituent of cell membranes? | phospholipid |
| Proteins do NOT pass through cell membranes because | they are very large molecules |
| The definition of osmosis is the | diffusion of water across a selectively permeable membrane |
| Nucleic acids are polymers of | Nucleotides |
| A membrane sac filled with large molecules of potassium is suspended in a beaker of water, What will happen? | Water will enter the sac and it will swell |
| Macrophages, a type of white blood cells, are able to remove bacteria from our bloodstream and tissues by | facilitated diffusion |
| Which of the following domains contains organisms that are adapted to life in harsh environments? | Domain Archaea |
| If the mitochondrion is the result of endosymbiosis, what membrane of the mitochondrion represents the engulfing vesicle? | The outer mitochondrial membrane |
| Which statement is false regarding science? | Correct scientific conclusions are permanent and never subject to change or refinement |
| When an intestinal cell ingests substances inside very small vesicles that can only be seen with an electron microscope, this is | Pinocytosis |
| An isotonic solution means that the solute concentration outside the cell | is the same as inside the cell |
| Removal of the hydroxyl functional group would disrupt the structure of ___________ |
