The correct answer is A. 20.2 s
Explanation:
The table shows there were three trials to measure how much time a toy car needs to move 1 meter on different surfaces. Now, to find the average time on a surface simply add the results of the three trials and divide this by number 3 (number of trials). The process to know the average time on dirt is shown below:
20 + 19.2 + 21.5 = 60.7 - Results of each of the trials
60.7 ÷ 3 = 20.2 s - Divide the total by the number of trials
This means the average time for the toy to move on dirt was 20.2s
The phenomenon where one gene can modify the effect on the second gene is known as epistasis.
In genetics, epistasis is a phenomenon in which the effect of a gene mutation is determined by the presence or absence of mutations in one or more other genes, which are referred to as modifier genes. To put it another way, the genetic background in which the mutation appears determines its effect. It has long been acknowledged that epistasis, or interactions between genes, is fundamental to comprehending both the structure and function of genetic pathways and the evolutionary dynamics of complex genetic systems.

The 1st answer (A) . That's called law of inertia.
Rest of the statements are true. But non of them are stated as laws.
The correct option is B.
Interdependence refers to the mutual reliance between living organisms.
The idea of interdependence in nature holds that all the living things on earth are interconnected as a result of their needs for matter and energy. They all depend on one another to survive. For instance, humans depend on green plants to produce oxygen which they used for respiration, while plants depends on humans to produce carbon dioxide which they use in the process of photosynthesis.<span />
