What do we breath.
Oxygen.
What is the element for Hydrogen?
H.
What is faster the speed of sound or the speed of light?
The speed of light.
Tell the teacher.
What type of reproduction do flowers use?
Asexual.
What is the greenhouse effect?
The layer of gases in our atmosphere that traps heat and keeps the Earth warm enough to have life.
Which is the most reactive group on non-metals?
Group seventeen is the most reactive group of non metals.
What waves have the longest wave length.
Radio Waves
What should you do to your hair during labs?
Tie it back.
What reproduction only used one parent?
Asexual.
Does melting land or melting sea ice have a greater impact on sea level rise?
Melting land ice.
What is the most reactive group of metals?
The metals in group one are the most reactive.
What is the line that connects equal areas of pressure on a map?
Isobars.
Use the emergency eye wash station.
Color blindness is a trait controlled by an X-linked gene. Normal vision (B) is dominant to color blindness (b). Paul is a boy with normal vision, and his mom is heterozygous with normal vision. What is Paul's colorblind Dads genotype? What is the probability of Paul's parents having a colorblind child?
The Dads genotype is XbY. The probability of a colorblind child is 50%.
What is the effect of increased temperature on the volume of ocean water?
The volume of ocean water increases.
What are the elements touching the zig-zag line (except for Aluminum) called? Name the four of them as well?
Metalloids. Boron, Silicon, Arsenic, and Germanium.
What happens to the speed of sound when the temperature changes?
Sound travels faster when the air is hotter.
Christian, Jack, and Paul are doing a lab when suddenly Paul drops a beaker full of dangerous chemicals he runs to get a mop but accidentally steps in the chemicals and is splashes all over Christian. What should they do? What did they do wrong?
Jack and Paul should go get the teacher to see if Christian is okay and help them clean up the mess. If the teacher says he should, Christian should go to the emergency shower and wash off. Paul shouldn't have been running and they should've gotten the teacher immediately.
A flower plant with genotype AB/ab ; Cc is crossed with a plant having genotype ab/ab ; cc. Genes A and B are linked and separated by 10 map units, while gene C assort independently. Researchers observe that among 400 offspring, the following phenotypes occur:
Phenotype Number
Red, Round 178
Red, Elongated 22
White, Round 18
White, Elongated 182
Using this information, determine: The recombination frequency between genes A and B.
10% (or 10 centimorgans, cM).
What is the ice-albedo feedback?
This positive feedback loop in the Arctic accelerates global warming because the loss of a highly reflective surface causes more solar energy to be absorbed by Earth.
What are I⁻ and Xe⁺?
Isoelectronic species.
According to VSEPR theory, the repulsion between bonding and nonbonding electron pairs gives water its bent shape; these nonbonding pairs are called these.
Ione pairs.
