A roller coaster is fastest at the front of the train. The shorter the hill the roller coaster climbs, the greater its kinetic energy. Potential energy is converted to kinetic energy as the roller coaster goes down the hill. No conclusion can be made from this evidence
1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of structure and organization in organisms.
3. Cells arise from pre-existing cells.
4. All cells maintain homeostatis.
Answer:
13% cytosine
37% thymine
Explanation:
Chargaff's rule states that the DNA always has a 1:1 ratio of purine bases (the cytosine and thymine to pyrimidine bases (guanine and adenine).
If there is 13% guanine, then there must also be 13% of cytosine (since G pairs with C)
The total of guanines and cytosines is 26%, meaning the total of A + T is 100% - 26% = 74%. That means there are 74/2 = 37% of thymine.
