Acceleration is defined as the rate of change of velocity
Since velocity is a vector, it has both speed and direction.
So, if the object is travelling in a straight line at a constant speed, then it will not be accelerating. Both Magnitude and direction are constant.
However, if the object is travelling in a circle at a constant speed, then it'll be accelerating. An Object going in a circle is constantly changing it's direction, which means velocity is changing, so there is an acceleration caused by a net force.
Hope this Helps :)
Answer:
The moths were typically white with black speckles, which helped them blend in. There was a mutation that caused some of them to be almost entirely black, which would make them easier to spot and get eaten. However, one event that left the trees covered in ash and soot was an advantage for these moths. They blended into the trees more so than the other ones, and there was a giant fluctuation of them. The mutated ones now had a better chance of staying camofluaged, and the white and black speckled ones were more likely to get eaten.

Answer:
The longer answer lies in the details of photosynthesis, the electromagnetic spectrum, energy and “special pairs” of chlorophyll molecules in each plant cell. ... As such, plants look green because they absorb red light most efficiently and the green light is reflected.
Explanation:
Green plants are green because they contain a pigment called chlorophyll. Chlorophyll absorbs certain wavelengths of light within the visible light spectrum. ... Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants
