Movement of molecules in a fluid or gas from a region of higher concentration to a region of lower concentration.
What is Diffusion?
100
a large molecule, or macromolecule, made of many monomers bonded together.
What is a polymer?
100
organisms that get their energy from nonliving resources, meaning they make their own food.
What is producers?
100
a cell has two copies of each chromosome: one copy from the mother, and one copy from the father.
What is diploid?
100
process by which light energy is converted to chemical energy; produces sugar and oxygen from carbon dioxide and water.
What is photosynthesis?
200
The diffusion of water molecules across a semipermeable mebrane from an area of higher water concentration to an area of lower concentration.
What is osmosis?
200
substrate that decreases the activation energy needed to start a chemical reaction and, as a result, also increases the rate of the chemical reaction.
What is a catalyst?
200
organisms that get their energy by eating other living or once living resources, such as plants and animals.
What is consumers?
200
a cell has only one copy of each chromosome.
What is haploid?
200
organelle composed of numerous membranes that are used to convert soalr energy into chemical energy; contains chlorophyll.
What is chloroplast?
300
drives molecules across a membrane from a region of lower concentration to a region of higher concentration.
What is active transport?
300
polymers that are made up of monomers called nucleotides.
What is Nucleic acids?
300
Another word for producers are...
What is autotrophs?
300
a form of nuclear division that divides a diploid cell into haploid cells. this process is essential for sexual reproduction.
What is meiosis?
300
any of the alternative forms of a gene that occurs at a specific place on a chromosome.
What is allele?
400
a soulution outside of the cell has the same concentration of disolved particles as the cell. Water moves into and out of the cell at an equal rate so the cells size remains constant.
What is isotonic?
400
the amount of energy that needs to be absirbed fir a chemical reaction to start.
What is activation energy?
400
another word for consumers?
What is heterotroph?
400
the physical characteristics of an individual organism.
What is phenotype?
400
uptake of liquids or large molecules into a cell by inward folding of the cell membrane.
What is endocytosis?
500
Soulution has a lower concentraton of dissolved particles than a cell. The water molecules are more concentrated outside the cell than inside.
What is hypotonic?
500
Catalyst for chemical reactions in living things. Lowers the activation energy and increase the rate of chemical reactions.
What is enzymes?
500
Model that shows the complex network of feeding relationships and the flow of energy within and sometimes beyond an ecosystem.
What is a food web?
500
a grid system for predicting all possible genotypes resulting from a cross.
What is a punnett square?
500
law that states that allele pairs separate independently of each other during gamete formation, or meiosis.
