What is reproduction?
What is asexual reproduction?
What is sexual reproduction?
1) The creation of offspring
2) One parent that makes identical offspring
3) Two parents making similar offspring - shared characteristics from both parents
Parents pass on their _____ to their offspring. This is called ________. Genes are made up of ___.
Genes, Heredity, DNA
What is maintaining homeostasis?
What are some examples of how humans do this?
1) When you keep a stable internal environment
2) Shivering when cold, sweating when hot
What is adaptation?
What are some examples of adaptations?
1) When an organism becomes better suited for the environment.
2) Camouflage, venom, webbed feet, fangs
What does being able to respond to stimuli mean?
What is a stimulus?
What are some examples of a human responding to stimuli?
1) It means that you have the ability to sense and react to change
2) Anything that causes a reaction
3) Pupils constricting due to the sunlight, loud bang that causes you to jump
What is growth?
What is development?
1) Increase in height or weight
2) Maturation - changing from child to adult
True or False?
Growth and Development can only occur in humans.
False
What is nutrition?
How is metabolism related to it?
1) The process of consuming nutrients for good health
2) Metabolism is the rate at which you process foods to create energy (how fast you consume the nutrients)
What is cellular respiration?
1) The process by which the body uses glucose (food) to release stored energy.
Explanation: Cellular respiration is the body’s way of breaking down glucose (sugar) to release the energy that’s stored in it for the cells to use.
What is excretion?
What are some examples of this?
1) Getting rid of waste
2) Sweat, urine, feces, saliva
All or part of the organism ______ at some point in time
Moves

2) Vulture, hyena
What are decomposers?
What are 2 examples of them?
1) Decomposers are organisms that break down dead organisms to recycle nutrients.
2) Mushrooms, bacteria, some worms
True or False?
Decomposers are microorganisms that break down dead organisms through chemical processes.
True
