4. Predictive
What makes isotopes different than regular atoms?
They have a different number of neutrons
Define learning.
A durable change in behavior brought about by experience
What letter represents the exponential curve, and what letter represent the logistic curve?
J - exponential
S - logistic
What is the greenhouse effect?
The natural process that warms Earth's surface by trapping heat in the atmosphere
What are the 3 challenges for science?
1. Loss of biodiversity
2. Emerging and reemerging diseases
3. Climate change caused by global warming
Organic molecules always contain a ____ and a ____
Define nature and nurture
Nature - the genetic component of behavior
Nurture - the environmental component of behavior
Define predation and give an example.
Occurs when one organism, the predator, feeds on another, the prey.
Ex. Animals such as a lion that kills zebra
What are 2 examples of reservoirs?
Fossil fuels and living/dead organisms (like trees)
"Makes generalizations based on collecting and analyzing a large number of specific observations," is inductive or deductive reasoning?
Inductive
What are adhesion and cohesion?
1. Adhesion - water adheres to a surface or object
2. Cohesion - water comes together in a cohesive unit
Explain classical conditioning versus operant conditioning.
Classical conditioning - Presentation of two different, usually unrelated, stimuli at the same time causes animal to form association
Operant conditioning - Stimulus-response strengthened, and usually involves a reward/punishment
Define density-dependent factors and density-independent factors and give an example of each.
1. Density-dependent factors - Biotic factors Competition, predation, parasitism
2. Density-independent factors - Abiotic factors Weather, natural disasters
What is the equation for photosynthesis?
Energy + 6 CO2 + 6 H2O --> C6H12O6 + 6 O2

What are the properties of water due to hydrogen bonding?
1. High heat capacity
2. High heat of vaporization
3. Cohesion and adhesion
4. Can dissolve many molecules
5. High surface tension
What are the 4 forms of animal communication and define them.
1. Chemical - Transmission of information between animals using chemical substances called pheromones, which are detected by an individual’s sense of smell
2. Auditory - The use of sounds for animals to convey information, essential for survival and social interaction
3. Visual - Animals use signals like body posture, color changes, and even light to convey information to other animals
4. Tactile - The exchange of information through physical touch
What are the three symbiotic relationships and what are the relationships like?
Parasitism - One benefits while the other is harmed
Commensalism - One benefits while the other is not benefitting or being harmed.
Mutualism - Both organisms benefit from each other.
What is the equation for respiration?
C6H12O6 + 6 O2 --> 6 CO2 + 6 H2O + Energy
