| Question | Answer |
|---|---|
| Nucleotide is to DNA as monosaccharide is to: | carbohydrate |
| Peroxidase is an enzyme that breaks down hydrogen peroxide in the cells. It accomplishes this because of its structure. What part of the enzyme is involved in this catalytic activity? | active site |
| Proteins are formed from monomers called | amino acids |
| Amino acids are linked together by peptide bonds to form proteins. In which organelle would proteins be assembled? | ribosomes |
| Examples of this macromolecule are fats, phopholipids, waxes, and steroids. | lipids |
| The building blocks of nucleic acids are | nucleotides |
| The basic unit of structure and function in living things is the | cell |
| Which cellular structures are associated with movement? | flagella |
| In the human body, the circulatory system transports and delivers substances. Within the cell, which organelle peforms a similar function? | Endoplasmic reticulum |
| A cell that has a cell wall, many organelles, including chloroplasts is a ___________ cell. | plant |
| A prokaryotic bacterium is different from a eukaryotic cell because it has no membrane bound _________. | nucleus |
| Unlike animal cells, plant cells have a large __________. | vacuole |
| What structure do all cells have in common? | DNA |
| What is responsible for the rough appearance of the endoplasmic reticulum? | ribosomes |
| Which organelle is the site of cellular respiration and is where energy is made available for the cell? | mitochondria |
| Unlike the cell membrane, the cell wall is made of tough _______ | fibers |
| The cell membrane ___________ which materials enter and leave the cell. | regulates |
| The movement of molecules from an area or high to low concentration is called | diffusion |
| When the concentration of molecules on both sides of the cell membrane is the same, the molecules will move across the cell membrane in both directions ___________. | equally |
| The molecules that move large, charged substances into and out of the cell are called. | proteins |
| To avoid growing too large, cells regulate their size by | dividing |
| The typical cell goes through a process of growth, development and reproduction called | cell cycle |
| The region on a chromosome that joins two sister chromatids is called | centromere |
| Teh bacterium Staphlococcus aureus can divide once every 20 minutes. It spends about 90% of its life cycle in | interphase |
| A leopard frog has normally 26 chromosomes in each body cell. How many chromosomes will each of his sperm cells have? | 13 |
| The process by which the cytoplasm and organelles divide is | cytokinesis |
| After cell division, a daughter cell will have properties like the parent because _________ is copied right before cell division. | DNA |
| Four haploid and genetically different gametes are produced during | meiosis |
| Sexual reproduction is important for a species because it allows _________ among the offspring that may help with survival. | variation |
| Crossing over may occur during which phase of Meiosis I? | Prophase I |
| The exchange of genetic material between homologous chromosomes that occurs during meiosis and contributes to genetic variability is called | crossing over |
| A reproductive cell having the haploid number of chromosomes A reproductive cell having the haploid number of chromosomes is called | gamete |
| During this phase of mitosis the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell. | prophase |
| During this phase of mitosis the chromosomes are aligned along the middle of the cell. | metaphase |
| During this stage of mitosis the chromosomes begin moving to opposite ends (poles) of the cell. | anaphase |
| The process by which DNA is copied is called | replication |
| In eukaryotes the DNA is found in the | nucleus |
