What is a push or a pull?
Define Weather.
Conditions of the atmosphere day to day. Temp, humidity, precipitation, wind speed....
What is a phenotype?
A physical trait. Blue eyes.
What is the function of the excretory system?
To filter waste out of the blood.
How does an amoeba move?
pseudopods
What kind of simple machine is a ramp?
inclined plane
Name the thunderstorm cloud.
Cumulonimbus
Define gene.
A segment of DNA that controls the protein production and the cell cycle.
What is the function of the digestive system.
To break food down into nutrients and to get rid of solid waste.
Is the cell membrane in both plant and animal cells? What does it do?
Yes. Controls what goes in and out of the cell.
Calculate the speed of an object moving traveling 100 kilometers in 5 hours.
20 km/hr
Earth's atmosphere is composed of what 3 gases.

Give an example of asexual reproduction.
budding or binary fission.
Explain how the circulatory system and the respiratory work together.
gas exchange occurs between the capillaries and the alveoli, the blood carries the CO2 and O2 to and from the lungs.

Explain how a gamete is different from other body cells.
it's a haploid, has half the chromosomes.
tendency to resist change in order to maintain a stable, relatively constant internal environment. Shivering
Compare and contrast an amoeba and a euglena. (how they move, feed)
Amoeba-pseudopods, engulfs food
Euglena- hetero and autotroph, had eye spot flagella
Both-heterotrophs and contractile vacuoles
Define Acceleration. (3 things)
Acceleration can be positive, negative and include direction. It's the rate of change of velocity.
Compare the arrangement of air molecules found in the troposphere with the mesosphere.
The air molecules in the mesosphere are further apart than the air molecules in the troposphere.
In a heterozygous cross of a (B) brown eyes and (b) blue eyes what percentage of the offspring will have blue eyes?
25%
Explain why it is important for the digestive, respiratory and circulatory system to work together.
Cellular respiration, so the cells can produce ATP (energy)
Compare and contrast mitosis and meiosis.
Mitosis-repairs, replaces, growth, diploid, identical
Meiosis-gametes, haploids
Both-cell division go through PMAT
