Answer:
objective observations
Explanation:
These observations are based on specific events that have already happened and can be verified by others as true or false.
Pretty sure I'm wrong
The more polar A compound moves ahead of the less polar B compound.
Explanation:
The analytical process that involves the separation of colored substance or chemicals is named as paper chromatography, a replacement of thin-layer chromatography. In this method, there is the use of two solvents and rotation of paper at 
. It helps in isolating two complex compounds of equal polarity.
A non-polar mixture of solvent is required in the mobile phase of this method. In accordance with the retention factor of this process, the more polar compound A will go further than compound B as the solvent is non-polar.
Answer:
Plasma membrane acts as a selectively permeable barrier between cell components and external environment. If plasma membrane breaks down, it would result in the release of cellular components including cell organelles and cytoplasm in the external environment ultimately leading to the cell death.
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>
