100
Making more of one's own kind.
What is reproduction?
100
The type of reproduction that results in variations in the offspring.
What is sexual reproduction?
100
Most of the energy on Earth comes from this and is the start of all food chains.
What is the sun?
100
The basic unit of all living organisms.
What is the cell?
100
Supports the body and works with the muscular system to help it move.
What is the skeletal system?
200
The release of energy by combining oxygen with digested food.
What is respiration?
200
When an organism has two different genes for a particular trait.
What is hybrid or heterozygous?
200
The only type of organism that can use the energy from the sun to make its own food?
What are green plants?
200
The site in which green plants make their own food by capturing sunlight energy.
What is the chloroplast?
200
Removes wastes from the body.
What is the excretory system?
300
Getting rid of waste products.
What is excretion?
300
The genetic cross done to show the percentages of the offspring to possess a certain trait.
What is a Punnett Square?
300
The gradual change in a species over time.
What is evolution?
300
The site in which both plant and animal cells store their food, water, and wastes.
What is the vacuoles?
300
Delivers oxygen to sites of gas exchange between the circulating blood and air.
What is the respiratory system?
400
Breaking down food into a form that can be used for life functions.
What is digestion?
400
When the genetic makeup of an organism are the same, example: bb.
What is a purebred or homozygous?
400
The organism that has the least amount of energy in the food chain below. seaweed -> small fish -> seal -> polar bear
What is the polar bear?
400
The outermost part of the plant cell, that gives it it's structure, that animal cells do not have.
What is the cell wall?
400
Breaks down food to be used as energy.
What is the digestive system?
500
Xylem and phloem are part of this function in plants and the heart and blood vessels are part of this function in animals.
What is circulation?
500
The trait that will only show up in an organism that is a purebred.
What is a recessive trait?
500
All food chains end with this type of organism, which feed on dead, decaying material.
What are decomposers?
500
The organelle that uses oxygen and glucose to make ENERGY for the cell to carry on all cell processes.
What is the mitochondria?
500
Controls the body by releasing hormones into the blood.
What is the endocrine system?
