Term | Definition |
Phase of mitosis when chromosomes line up along the middle of the dividing cell: | Metaphase |
One product of cellular respiration | water |
diffusion | movement of molecules from an area of high concentration to an area of low concentration |
osmosis | movement of water across a semi permeable membrane |
translation | the cell uses information from mRNA to produce proteins |
controlled experiment | tests the effect of a single variable |
organelle that releases energy from sugars and other molecules | mitochondrion |
organisms that make their own food | autotrophs |
organisms that eat other organisms | heterotrophs |
An animal cell that is surrounded by fresh water will burst because | osmosis causes water to move into a cell |
particle transport that requires input of energy from the cell | active transport |
Type of RNA that functions as a blueprint for protein synthesis | mRNA |
The work of scientists generally begins with: | making observations and asking questions |
genes contain instructions for assembling: | proteins |
The function of a nucleus | store DNA, direct activities of the cell, contains the information to make proteins |
genes that are located close together on the chromosome | rarely assort independently |
nondisjunction | failure of homologous chromosomes to separate during meiosis |
number of chromosomes in a normal human karyotype | 46 |
cells that do not have a nucleus | prokaryotes |
DNA replication happens in this cell cycle phase | S phase |
