Answer:
d. and e. I believe would be the correct answer
DNA consists of two types of nitrogenous bases: Purine and Pyrimidine. Purine is a double ringed structure that includes Adenine (A) and Guanine (G) while pyrimidine is a single ringed structure that includes Thymine (T), Cytosine (C) and Uracil (U). In a DNA helix pairing takes place between one purine and one pyrimidine. A pairs with T and U (in case of RNA) and G pairs with C. During a mutation, it is more likely for A to get mutated to G than to T because A and G are similar in structure than T and C and the structure of DNA is not changed.

Urea inactivates the enzyme function via denaturation of its secondary and tertiary function. Without its secondary or tertiary function, it’s 3D structural conformation is altered and it will be unable to perform its function.
If vector is less than 90° and greater than 0°, it’s positive. if it’s less than 180 and greater than 90, it’s negative. if there is no acceleration vector, it’s called zero acceleration.
