A type of reasoning that involves experimentation and observation to establish general principles
What is inductive reasoning
100
These are the strongest type of chemical bonds where two atoms share an electron
What is a covalent bond
100
The four major types of biological macromolecules
What nucleic acids, proteins, carbohydrates, and lipids
100
Instrument that allows the study of surface structures of cells.
What is scanning electron microscope
100
these are two examples of secondary structures in protein
What are alpha-helices, beta-pleated sheets
200
These are 2 of the 7 defining characteristics of living things
What is 1) cellular organization, 2) metabolizes energy, 3) can maintain homeostasis, 4) can reproduce, 5) can grow and develop, 6) can respond to environment, 7) environmental adaptation
200
A particle which carries a + or - charge due to the loss or gain of an electron
What is an ion
200
these are the primary molecules that make up biological membranes (be specific!)
What are phospholipids
200
In general, smaller cells are more efficient than larger cells. This is because they have a larger ____________________.
That is surface-to-volume ratio
200
two types of molecules that are used energy storage both short term and long term (name both)
What are carbohydrates and lipids
300
The hierarchy of organization within biology (going from an atom up to a single organism)
What is (atom) molecule, organelle, cell, tissue, organ, organ system, organism
300
This number of this particle changes between to atoms in order to create an isotope
What are neutrons
300
If a protein in denatured, this level of protein structure is NOT affected
What is primary structure (the order of amino acids does not change).
300
Organelle that is the center of control in the cell.
What is the nucleus
300
find the word to finish this analogy: chemical reaction is to equilibrium as organism is to THIS
What is homeostasis
400
this phenomenon is caused by genetic changes in a species over time and is shaped by natural selection
What is evolution
400
A substance that will increase the amount of H+ ions when dissolved in water
What is a acid
400
the level of protein structure that is determined by the polar and non-polar interactions between the amino acids' functional groups within a polypeptide strand
What is tertiary structure
400
It states that all life is composed of cells and that all cells arise of pre-existing cells.
What is The Cell Theory
400
This is the level of hierarchy which includes the populations of all species in an area minus the natural environment
What is a community
500
The 5 steps of a scientific investigation, in reverse!
What is making conclusions, testing/experiments, making predictions, forming hypotheses, formulate a question, and observation.
500
A polar molecule, which also makes it a "water loving" or __________________ molecule
What is hydrophilic
500
The two types of bonds that hold a molecule of DNA together
What are hydrogen bonds (across the strands) and phosphodiester bonds (along the backbone)
500
Proteins are synthesized by ______________, get folded in the ______________, travel in ___________ vesicles to the __________ where they are sorted to be delivered to different parts of the cell.
What are ribosomes, Rough ER, transport and Golgi.
500
In an experiment measuring kids preference of kool-aid based on sugar content, you make 3 types of kool-aid with low, medium, or high amounts of sugar. You graph how many glasses of kool-aid each kids drinks. This is the dependent variable
What is the number of glasses of kool-aid each kid drinks
