Water
Carbon Dioxide
Oxygen
Sunlight (Light Energy)
Glucose (Sugar/food)
Select all that are products (outputs) of photosynthesis.
Water
Carbon Dioxide
Oxygen
Sunlight (Light Energy)
Glucose (Sugar/food)
The main difference between photosynthesis and chemosynthesis is:
Photosynthesis gives off carbon doxide, while chemosynthesis gives off oxygen
photosynthesis happens in the dark, while chemosynthesis happens in light
photosynthesis uses chemicals (hydrogen sulfide) to make food, while chemosynthesis uses light
chemosynthesis uses chemicals (hydrogen sulfide) to make food, while photosynthesis uses sunlight
Select all of the requirements (inputs) for cellular respiration.
Water
Carbon Dioxide
Oxygen
ATP (Cellular Energy)
Glucose (Sugar/food)
Select all that are products (outputs) of cellular respiration.

Apple Tree
Owl
Skunk

An organism that produces its own nutrients from inorganic substances or from the environment instead of consuming other organisms is called an (a) .
An organism that obtains organic food molecules by eating other organisms or their byproducts and that cannot synthesize organic compounds from inorganic material is called a (a) .
This characteristics of life called (a) describes the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation
Negative feedback loops result in stabilization of a system.
Negative feedback is a process that _______ the signal that started the stabilization process.
reduces
amplifies
has no effect on
Positive feedback loops result in a system moving towards an extreme. Positive feedback is a process that _______ the the signal that started the process.
reduces
amplifies
has no effect on
In humans, maintaining a constant internal body temperature requires which type of feedback loop?
When your body senses that signal that glucose levels in the blood rising, your brain sends a signal to your pancreas. The pancreas then releases insulin, which opens channels in cell membranes to allow glucose to enter the cell, lowering blood sugar levels.
If an endotherm is in cold weather, which of the following will most likely happen to help that organism maintain a constant internal temperature?
The organism will shiver to decrease the internal temperature.
The organism will sweat to increase the internal temperature.
The organism will shiver to increase the internal temperature.
The organism will sweat to decrease the internal temperature.
This type of organism regulates its internal body temperature to maintain a constant temperature.
Endotherm
Ectotherm
This type of organism's internal body temperature changes as environmental temperatures change.

Which of the following structures in a flowering plant's reproductive system produces pollen?
Anther
Ovule
Ovary
Petal
(a) is the transfer of pollen grain from the anther to the stigma within one flower or between flowers of the same kind; usually an organism assists with this process through its own natural behaviors.
The seeds of a flowering plant can be found inside the (a) .
This structure encloses the egg cells inside the ovaries of a flowering plant.

Which of the following describes one concept explaining why two organisms are members of the same species?
Organisms are part of the same species if they reproduce
Organisms are part of the same species if they can produce fertile offspring
A (a) is a change in genetic information that can result in new traits.
An inherited trait that increases an organism's chance of surviving and reproducing is called a(n) (a) .
When an organism of a species has an adaptation, it will compete for resources better, survive longer and pass that adaptation on to it's offspring. As generations pass, more adaptations can be accumulated. This process is called
evolution by natural selection
artificial selection
mutation
adaptation
Which of the following is a true statement regarding evolution?
An individual organism within a population is said to evolve when it develops a mutation.
Evolution happens over many generations at the population level.
Natural selection can act on populations that are completely genetically identical.
An organism can choose to adapt to its surroundings when needed.
"I jumped into the rushing river and it took my breath away. It took a few minutes until I adjusted to the temperature." This statement best describes which process?
