Morning commuter traffic in cities contributes to ____ smog. In this type of air pollution, a mixing of ____ from certain plants
azamat

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>

He light colored rock pocket mice in New Mexico blend in with the sandy soil of the area, but on darker lava flow, the light col
fiasKO [112]

<u>Answer</u>: option B they have a random gene mutation that affects their fur colour.

<u>Explanation</u> :-

  • <em>Variation</em> is the phenomena which occurs in all populations.
  • These variations result in slight differences in the phenotypes of individuals .
  • These variations only arise due to <em>random mutations </em>that arise in the individuals’ genome and then can be inherited by their offspring.
  • There is always a probability of one particular trait to make the individuals survive better in the environment as compared to other trait.
  • The individuals having the trait that helps them to survive better in the environment tend to survive more and leave more progeny. This is termed as <em>survival of the fittest</em>.
  • Thus, according to the question it can be inferred that the dark fur colour arose due to a <em>random mutation </em>since it is the only source of variation. Since, in the given environmental conditions the mice having the dark fur colour were less susceptible to the predators they are better fitted to survive.
  • The dark brown fur coat mice, survive better, leave more progeny and hence, increase their population with time. However, the orginal source of origin of this trait was a random mutation. Had this mutation not occured, the dark coloured fur mice would not have been there.

So, a <em>random gene mutation affecting the fur colour made the dark coloured mice first appear in the population.</em>

Water leaves the internal cavity of a sponge through the
Trava [24]

If I'm not mistaken, it leaves through the osculum which is a cavity located on the upper part of a sponge.

Sponges feed through a process called filtration, which means that they filter the water in search of nutrients. And after they collect everything they need from the water, they need to let it out somehow; through the osculum.



Hope it helped,
