Answer:
photochemical
hydrocarbon
Explanation:
Morning commuter traffic in cities contributes to<u> photochemical</u> smog. In this type of air pollution, a mixing of <u>hydrocarbons</u> from certain plants, nitrogen oxides from cars, and UV radiation from the sun results in a variety of pollutants, such as ground-level ozone, which can cause coughing and breathing problems.
<em>Photochemical smogs are caused by the photochemical reaction of hydrocarbon and nitrogen oxides in the lower atmosphere with sunlight playing a major role. The reaction of the hydrocarbon with the nitrogen oxide in the presence of light leads to the evolution of ozone gas while nitrogen oxide has the capacity to react with the sunlight on its own to produce nitrogen dioxide. This result in the formation of smog</em>
1)magnification goes by 10x (read 10 times), 100x,1000x and some goes 10,000x
2)Always focus first using lowest power possible first, switch to medium power (100x) after it's focused on low power(10x), on 100x, use the small knob to focus it more. DO NOT touch the bigger nob when in medium or high power. Switch to high power (100x) when it is focused on medium power, again focus again using the small knob on high power.
3) So it doesn't gather dust and fog up the lense? that one should be self explanatory
Most boreal forests are dominated by CONIFEROUS EVERGREEN TREES. The correct option is E. Boreal forests can be found in Canada, Russia and in Alaska in United states. Most trees in these forests are conifers with needle leaves and cones, examples include: black spruce, white spruce, balsam fir, jack pine, etc.
Answer:
The correct answer would be efferent neurons.
Efferent neurons are the motor neurons which communicate information in the opposite direction as compared to the afferent neurons, that is, they communicate information or response impulses from the brain or central nervous system to the muscles or glands.
The response impulses results in the movement of the muscles or activation/deactivation of certain gland
In contrast, afferent neurons are the sensory neurons which carry impulses from the receptors to the central nervous system.
Answer:
A
Explanation:
The energy carried by electromagnetic waves is sometimes referred to as radiant energy. Electromagnetic waves do not require a medium for propagation hence they can travel through vacuum and are known to transmit enormous amount of energy.
Electromagnetic waves transmit energy away from the source of the wave. Hence the answer chosen in the answer section above.
