Explanation:
The tobacco plant species have its leaf colour with characteristics that changes gradually over a range of values, which refers to continuous variation.
Note that continuous variation keep expressing gene variants in successive generations of the tobacco plants, that differs from the parents. So, there are MORE THAN four genes controling the expression of varying phenotypes in the leaves
Answer:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
Answer:
Moistening food and helping to create a food bolus so food can be swallowed easily
A law is supported by scientific evidence that is reproducible, whereas a hypothesis is simply a guess that can be confirmed or refuted by an experiment.
<h3>What exactly is a hypothesis?</h3>
A hypothesis is a guess based on a large amount of background information. If only five trees survived, they may have received more light than the other five.
In that case, one will devise an experiment in which the same plant is randomly assigned to different treatment groups with varying degrees of light, and the rate of growth of each group is compared.
Thus, a law is supported by scientific evidence that is reproducible, whereas a hypothesis is simply a guess that can be confirmed or refuted by an experiment.
