Biology is the study of_________.
Life
atom
this organelle is found at the center of the cell and contains genetic information
nucleus
What kind of transport requires the cell to expend no energy?
passive transport
What are the smaller pieces that make up DNA
nucleotides
The variety of life across the biosphere is ?
Biodiversity
the four main types of carbon-based molecules in organisms are
carbohydrates, lipids, nucleic acids, proteins
the three parts to cell theory are
all living things are made up of cells
cells are the most basic unit of life
all cells come from pre-existing information
this type of transport requires water to diffuse from an area of high concentration to an area of low concentration
osmosis
what is the central dogma of biology?
DNA-> RNA-> protein
During an experiment, factors that can be changed are known as __________.
independent factors
this bond requires atoms to share their electrons
covalent bond
a vacuole primarily stores this
water
this type of transport can referred to as the cell is "eating"
phagocytosis
What is the final product of translation?
Never pour water into _______ but pour it slowly into water.
This attraction causes water and other liquids to stick to each other.
cohesion
What takes place in the mitochondria
cellular respiration
this type of diffusion requires "help" from proteins to move materials into and out of the cell
facilitated diffusion
What are codons?
3 mRNA nucleotides
When do you use a line graph?
to show change over time
Explain the difference between endothermic and exothermic reactions
endothermic: energy is reabsorbed
Exothermic: energy is released
how are photosynthesis and cellular respiration related?
the products of photosynthesis are the products of cellular respiration
what type of transport would be needed for material to exit the cell.
exocytosis
what are the DNA base pairing rules?
A-T
G-C
