How would you describe the relationship between the mass of a car and its kinetic energy?
2 answers:
Answer:
The answer is A) As the mass of a car increases, its kinetic energy increases.
Explanation:
Kinetic energy is the energy associated with bodies that are in motion, depends on the mass and speed of the body, that is, The kinetic energy of a body depends on its mass and its speed according to the relationship.
The kitenic energy is expressed by the formula:
Where the kinetic energy, (Ec) is measured in joules (J), the mass, (m) is measured in kilograms (kg) and the velocity, (v) in meters / second (m / s).

One hypothesis that explains the result is : A) Two genes are involved with 12:3:1 epistasis, such that A_B_ and A_bb are black, aaB_ is brown,and aabb is green.
Explanation:
- This is a case of Dominant Epistasis.
- When two genes are involved and presence of dominant allele of one gene masks the effect of either allele of the second gene then the epistasis is termed as dominant epistasis.
- In the given case black :brown: green ratio is approximately equal to 12:3:1.
- Here presence of a dominant A allele that is responsible for the black colour masks the effect of either allele of B. Therefore A_B_ and A_bb produces black beetles
- Again , absence of dominant A allows B to express itself and Brown beetles are produced thus aaB_ is brown.
- When both the genes are present as recessive alleles, neither brown nor black colour is expressed and the beetles are green.Thus, aabb are green.
