In his analysis of different species’ DNA, E.Chargaff discovered the base-pairing rules of DNA.
1.) Chargaff’s rules state: The amount of adenine is equal to ? and the amount of cytosine is equal to ? .
2.) if a sample of jellyfish DNA is 14% cyotsine, approximately how much adenine would there be in that same sample? Show your work.
Answer:
1. Thymine, Guanine
2. 36% Adenine
Explanation:
1. Edwin Chargaff, who proposed the complementary base pairing rule, stated in his rule that the amount of purine bases (Adenine and Guanine) is equal to the amount of Pyrimidine bases (Cytosine and Thymine). This means that, in a DNA molecule, the amount of adenine is always equal to Thymine (A=T) and the amount of Cytosine is equal to Guanine (G=C).
Also, the total amount of the four nucleotide bases that make up a DNA molecule is equal to 1 or 100% i.e. A+T+G+C= 100%
2. Based on the rule above, if a sample of jelly fish DNA contains 14% Cytosine, the amount of its complementary pair (Guanine) will also be 14%.
Hence, Cytosine and Guanine will collectively occupy 14+14=28% of the DNA.
To find the amount of the other two bases i.e. Adenine and Thymine, we subtract 28% from 100%
That is, 100 - 28 = 72%
If both Adenine and Thymine contains 72% and each must be equal, we divide 72% by 2 to get the amount of each.
Hence, 72/2 = 36% of Adenine and 36% of Thymine.
According to the question, Adenine will contain 36% in the Jellyfish DNA.
Soil at the shore of Lake Erie in Pennsylvania has a high sand and gravel content. Which of the following is a characteristic of this type of soil?
A) extreme acidity
B) rapid water drainage
C) extensive producer biomass
D) significant depth before hitting bedrock
Answer:
rapid water drainage
Explanation:
These are example of granular (sand and gravel)soils.They are more permeable to water, and therefore can not retain water molecules.They are non-cohesive soil,with high strength and capacity to withstand slope.
High acidity is not a characteristic feature of soil with sand and gravel.In addition, such soil lacks biomass therefore can not support plant growth. The soil type is not a yardstick to determine the dept of soil type.Consequently, rapid water loss due to porosity is the best option.

Do you think percent daily value (% DV) is a useful tool, even for people who don't consume a 2,000 calorie diet? Explain

Answer:
Yes because it gives off a sense of how high a particular food is, or the oppostite, how low it is for a specific nutrient.
Explanation:
This is the sample answer but reworded so no one gets striked for cheating. the answer above is the sample answer.
Hope this helps :3
Yes, the percent daily value (% DV) is a useful tool, even for people who don't consume a 2,000-calorie diet.
What is the percent daily value?The percent daily value may be defined as the value which is usually calculated by dividing the amount in a serving by the total recommended daily amount.
It indicates the value of each nutrient in a serving of the food specifically. It gives an idea to the person how more he/she is already taken in terms of calories or may be short with respect to daily recommendation limits.
Therefore, it is well described above.

Which formations are created by wind deposition? Select two options.
spits
deltas
loess hills
kettle lakes
sand dunes
Answer:Loess Hills and Sand Dunes
Friend me!!!!
Explanation:Loess is made of silt that were wind blown from vertical cliffs.
Sand dunes are basically hills of sand. They form when wind is impeded by a rock and it drops some of the sand as it hits the rock. Slowly the deposited sand builds up to form bigger dunes.
Hills since sand dunes are hills also, this is also considered a formation made by wind deposition.
Answer:
I believe it is loess hills and sand dunes

How is climate change like a game of Tetris? How can kids stop climate change? What are some of the ways that you will help?
Answer:
Climate change is like a game of Tetris because a lot of little things add up to it. you don't fill up the screen in Tetris in one move, small things build up over time.
Kids can stop climate change by being environmentally conscious and making an effort to reduce the size of their carbon footprints. They can choose to take public transportation instead of driving to school, they can take colder or shorter showers, and they can reduce their waste by using reusable bags at the grocery store or reusable cups instead of throw aways.
Some of the ways that i will help is by bringing my own reusable cup next time i get a soda at the gas station and taking shorter showers.
Explanation:
you can say whatever you want for the last part i know gas station dews aren't everyone's thing.
In your OWN words, describe the cardiac cycle
Answer:
The cardiac cycle is defined as a sequence of alternating contraction and relaxation of the atria and ventricles in order to pump blood throughout the body. ... In other words, when the atria are in diastole, the ventricles are in systole and vice versa.The cardiac cycle describes all the activities of the heart through one complete heartbeat—that is, through one contraction and relaxation of both the atria and ventricles. ... The volume of the ventricles remains unchanged (isovolumetric) during this period.
Explanation:
