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.
Explanation:
Grounding and insulation will be the two most recognized means of preventing injury during an electrical equipment operation. The workers should always place a non-conductive material like plastic around the conductor of electricity. When grounding, there needs to be a direct connection to either a cold water pipe or even metal. Without doing either grounding or insulation, there is a chance of burns, shocks, fire, and in extreme cases death.
A. It’s the thing you change and you’ll measure the E. coli growth
Answer:
<em>A. The air pressure in that section of Earth’s atmosphere decreased.
</em>
Explanation:
In the free air, the density of the air diminishes as the air is warmed. On increasing the pressure, the density also increases. The air is packed. The density increments as pressure increments.
The thickness and density of air decline with the increase of height because of that the surface area of the Earth's climate diminishes with increase in height, along these lines gas particles can spread out.
The density of the air is most minimal at a high rise on a hot day when the pressure of the atmosphere is low.
Examples of current electricity are like starting a car, turning on a light, cooking on an electric stove, watching TV, shaving with an electric razor, playing video games, using a phone, and charging a cell phone.
Hope These examples helped. :D
