Answer:
The correct answer is option a.
Explanation:
Power output refers to the power exerted at the time of performing physical activities. Power output is one of the best means of determining athletic performance at the time of exercise or any physical activity. When the athlete jumped over the treadmill, his output power enhanced abruptly, while the power input enhanced slowly over a duration of one to two minutes.
<span>Animals gradually adapt to changes within their environment over time. This gives them a better chance of surviving rather than going extinct because of the change. Say there is a gene mutation affecting color within a population of beetles in a rain-forest. All of the beetles used to be red, but now a few of them have experienced a gene mutation and are green. Because they live in a rain-forest, it is likely that the green beetles would blend in with their surroundings far better than the original red beetles, and those red beetles would be wiped out by predators because they are easier to spot. The green beetles would live on and flourish, and their population would increase. Soon there would be few or none red beetles, and many green beetles.</span>

Explanation:
A model is a representation of an idea, process that scientists use in explaining a complex data to a more simple and understable way. Models reflect the natural world e.g. climate models are used by humans to learn and to know about carbon cycles, water cycles and the weather. Model do come with some limitations one of them is an incomplete detail e.g. measuring the distance round the earth, we were made to believe that the model of the Earth is spherical, so in calculating the distance round the earth certain details are missing like the variations in distance caused by valleys and mountains and other topological problems that might be encountered.
