Biology
What is the structure of living organisms in order?
atoms, cells, tissue, organ, organ system, organism
What organelles DO bacterial cells have
flagella, circular DNA, plasmids, cell wall
What are the two types of mixtures?
Homeogeneous and heterogeneous
What is a dot a cross diagram?
A diagram to show either the movement of electrons or the electrons being shared between two or more atoms.
What is the formula for speed?
Speed = distance / time
What are the characteristics of living organisms?
MRS GREN (movement, respiration, sensitivity, growth, reproduction, excretion, nutrition)
What is the function of the cytoplasm?
gel like substance where all chemical reactions occur
If I have a solution of dissolved substances in a liquid, what kind of mixture is it?
Homogeneous (cannot distinguish specific parts)
What is an ionic bond?
An ionic bond is where electrons are transferred between elements to form a complete outer shell of electrons.
What does the area under a speed time graph represent?
distance (meters)
What structures are unique to PLANT cells?
permanent vacuole, chlorophyl, chloroplast
How would you calculate the volume of an irregulary shaped object?
Displacement method of water.
Electrons are equal to....
the number of protons
what is a covalent bond?
a bond of shared electrons that forms a neutral (no charged) bond between two or more elements to form a complete outer shell of electrons.
what is the formula for volume of a rectangle?
length x width x height (answer is cubed)
What structures do PLANT and ANIMAl cells share?
nucelus, cell membrane, ribosomes, cytoplasm, mitochandria
If something is being removed from the cell, such as CO2 waste, what characteristic of living organisms is being portrayed?
excretion
What is an element that takes an electron called?
anion (negative charge overall)
How do you find the number of neutrons in an element?
subtract mass number and proton number (proton number is ALWAYS smaller number)
If something is asking you for the difference, what is it asking you for?
To subtract the two answers to find the amount inbetween
What is the formula for magnification?
magnification = image size / actual size
Name the three specialized cells we discussed
Red blood cells, mesophyl cells, root hair cells
What type of bond will form between a metal and non metal?
Ionic
If something is asking you to draw BOTH the formation and final product of a dot and cross structure, what will is look like?
first image will show uneven outer electron shells, have arrow(s) showing either moevement or sharing of electrons. Draw another diagram with final product (charges if applicable, full shells, etc)
What is the correct verbage for a speed time graph?
constant acceleration, constant decelleration, constant speed, stationary
