Early Earth
It's the variety of life-forms that exist on Earth.
Biodiversity
Its an evolutionary tree diagram based on shared traits
Cladogram
In pea plants, purple flowers are dominant over white flowers. If a homozygous dominant plant was crossed with a homozygous recessive plant for flower color, what percentage of their offspring would have white flowers?
0%
It's the layer of the Earth's atmosphere in the which the ozone layer is located.
Stratosphere
These tools are used by meteorologists to collect data about air pressure
Barometers
It contains all the fossils found on Earth.
The fossil record
The ability to roll your tongue, your hairline and your eye color are all examples of these.
Inherited traits
If two heterozygous plants were crossed for seed color, (yellow is dominant), give the percentage for each genotype.
YY - 25%
Yy - 50%
yy - 25%
This layer of the Earth's atmosphere contains most of it's mass.
Tropospher
Water moves from the ground into the atmosphere by this process.
Evaporation
It's the process of dating fossils relative to which rock layer they are found.
Relative Dating
They are made up of tightly wound DNA molecules.
Chromosomes
If a heterozygous tall plant (dominant) is crossed with a short plant, what is the ratio of tall to short offspring?
2:2
The most abundant gas in the atomosphere.
Nitrogen
They are the lines on an air pressure map.
Isobars
The approximate age of the Earth.
4.6 billion years
A larkey has a genotype of "TT" or "tt" for tail type. How would you describe this genotype?
Homozygous (purebred)
Assume blue eyes are dominant to green eyes. Charles is homozygous for blue eyes. He marries Margaret who is heterozygous. What are the possible phenotypes for their children?
Blue eyes
It's the hottest layer of the Earth's atmosphere.
Thermosphere
Find the mass of 250 mL of benzene. The density of benzene is 0.8765. Show your work, label in grams, round to the nearest hundredth.
219.13 g
Acanthostega is one of the first known examples of one of these 4-limbed vertebrates.
Tetrapod
The letter "e" represents the eye color for a larkey. Red eyes are doominant in larkeys and grey eyes are recessive. What is thegenotype for a larkey that is purebred for red eyes?
EE
When a pea plant with green pods (dominant) is crossed with a plant with yellow pods, all the offspring have green pods. What are the genotypes of the parent plant?
GG and gg
Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere
What is the density of a 50 gram block of aluminum that measures 6 cm wide, 10 cm long and 9 cm high?
