What is a mutation?
A change in the DNA sequence
Where is DNA stored?
Nucleus
Plants use sunlight to make what sugar?
Glucose
What gas is released during respiration?
Carbon
Name one limiting factor.
Food, Predators, water, space, sunlight
What is an adaptation?
A trait that helps an organism survive and reproduce
What is the main function of DNA in a living organism?
The main function of DNA is to store and pass on genetic information. DNA contains the instructions that tell cells how to grow, function, and reproduce.
What gas do plants take in?
Carbon Dioxide
What process releases energy from food?
Cellular R.
What happens if a population gets too large?
Resources run out and the population decreases
What is natural selection?
The process where organisms with helpful/benefical/advantageous traits survive and reproduce more
If a DNA strand is ATC-GGA, what is the complementary strand?
TAG-CCT
What gas do plants release?
Oxygen
What is the main energy molecule cells make?
ATP
What are biotic factors?
Living organisms such as plants, animals, fungi, and bacteria in an ecosystem.
Why might a population of insects become resistant to pesticides over time?
insects with resistant traits survive and reproduce
If a DNA strand is TAC-GCA-TTT, what is the mRNA strand?
AUG-CGU-AAA
What is the equation to photosynethesis?
Carbon dioxide + water + sunlight → glucose + oxygen
What is the equation to Cellular Respiration
C6H12O6+6O2→6CO2+6H2O+ATP (energy)
What are abiotic factors?
Abiotic factors are the nonliving parts of an environment that affect living organisms.
Examples of abiotic factors include:
What is the difference between inherited traits and learned behaviors?
Inherited traits are passed through genes; learned behaviors are taught or experienced
