Weather/Atmosphere
Which gas is our atmosphere mostly comprised of?
Nitrogen
Name at least 2 characteristics of living things
respond, made of at least one cell, growth and development, use energy/metabolize, and reproduce
What is the simplest form of life? (tissue, organ, etc)
CELL
Explain the difference between offspring in sexual reproduction vs offspring of asexual reproduction
Sexual reproduction= unique offspring; needs male and female
Asexual reproduction- identical offspring; happens alone
What reference point would make a moving car appear to be moving- being inside the car or outside the car?
Outside on the road (not moving)
Which layer of the atmosphere do we live in?
troposphere
How many cells does a protist have?
ONE
Which system is responsible for hormone production?
Endocrine
Recessive means the trait does not show. It is masked.
How does the amount of force needed to move an object change with mass?
F= ma. More mass= more force needed to move the object
Where is air pressure the greatest- high in atmosphere or lower near sea level?
Lower!
Since most protists, like bacteria, produce asexually, what will their offspring look like?
Identical to them!
What is the term for internal balance in response to external stimuli (like too much heat or too cold)?
homeostasis
B= brown eyes, which is dominant to b= blue eyes. How do two brown eyed parents make a blue eyed child?
Both parents are heterozygous (Bb) or carry the recessive gene
Explain what 3 types of motion are happening on the graph I hold up
Constant acceleration, stopped, then going backwards/decelerating
What is convection and how does it impact weather?
Convection is when warm air rises and cool air falls.
It is what causes rain/weather (water cycle) and breezes
Name at least two differences between plant and animal cells.
Plant cell has cell wall and chloroplast
Animal cell has centriole
Vacuole in plant cell is larger
The circulatory system transports 3 main materials. List them. (one from digestive, one from respiratory, one from excretory)
nutrients, oxygen, waste (red/white blood cells will also be accepted)
Explain the difference between a Punnett Square and a pedigree chart
Punnett Square is a guess- it predicts probability offspring will have a trait
Pedigree tracks traits we know exist- often diseases
Two students are arm wrestling. John pushes LEFT with a force of 10N. Sam pushes RIGHT with a force of 15N. Who wins and by how much force?
Sam by 5N to the right
Explain how high and low air pressure impact weather
High pressure= clear, sunny skies
Low pressure= rainy/cloudy
Which part of a cell is responsible for energy production?
Mighty mitochondria!
Name two systems that work with the skeletal system/explain how
With muscular to help us move
With immune since white blood cells are formed in bones and help fight germs
With circulatory, since it transports blood cells.
Gray fur is dominant to white fur. A heterozygous mouse and a white mouse mate. What is the expected ratio of gray to white in the offspring?
50% (or 2:2)
How does the mechanical, potential, and kinetic energy change when a cup goes from being on a table to falling on the ground.
Mechanical energy never changes
There is more potential when the cup is on the table. Then, the energy changes to kinetic as it falls.
