replicate
Isotopes have the same number of ___ and different number of ____
Polar covalent
Carbs, lipids, nucleic acids, and ____ are the 4 macromoelcules
Proteins
A detectable change in the internal or external environment
Stimulus
Which control SHOULD have an effect?
Positive control
Isotopes have same ___ number and different ___ number
same atomic number and diff mass number
This bond shares electrons equally
Non polar covalent
Made up of fatty acid chains and are hydrophobic/non polar and insoluble in water
Lipids
Includes all the chemical reactions occurring within an organism
Metabolism
Negative
Which isotopes changes or decays overtime?
A unstable isotope
Not a bond but these are described as weak distance dependent attractions between neutral atoms or molecules
Van der waals
Give the body short term energy. These get broken down and transferred to ATP
Carbs
A researcher changes the temp of water and measures how quickly sugar dissolves. What is the dependent variable?
Time required for sugar to dissolve
No fertilizer/plain water is an example of which control?
Negative
Overtime which isotope will start to under radioactive decay?
Unstable
This compound does not dissolve in water and tends to separate
Hydrophobic
Made up of amino acids and help with immune system, muscle, cell structure, cell membranes, etc (Antibodies go with these)
Proteins
Students expose identical plants to different colors of light and count the oxygen bubbles produced. What is the independent variable?
Positive
During radioactive decay unstable isotopes can transform into other ____
Elements
This compound interacts favorably with water and tends to dissolve
Hydrophilic
This includes DNA (genetic info) and RNA (helps make proteins)
Nucleic acids
True or false: Sexual reproduction generally produces more genetic variation?
TRUE
