The Ozone layer is the the atmospheric region called the stratosphere, and shields us from harmful ultraviolet B radiation that comes from the sun.
Which are best answers?
No - Ozone holes can be hole-shaped. - Actually the ozone holes are not actually holes, but an area where the ozone has been depleted or thinned.
Yes - Ozone holes allow ultraviolet light to reach the Earth's surface. - When ozone levels decrease, it allows UVB radiation to pass through and our surface is exposed.
No- Ozone holes don't have any ozone in them. - Ozone holes have lower levels of ozone in that area of the stratosphere.
Yes - Chlorofluorocarbons make an ozone hole larger. This is called the greenhouse effect. When we warm the earth's surface with these types of gases, they can trap energy from the sun. This makes it warmer on earth's surface. There has been a scientific link between CFC gasses and ozone depletion.
Yes - There is always just one ozone hole in the Earth's atmosphere. - The ozone hole forms over Antarctica because its winter allows the atmosphere to get cold enough for nacreous clouds to form in the ozone layer.
No - Ozone holes have more ozone than usual. - Ozone holes are areas where the ozone levels are depleted.
Answer:
primary demand and selective demand
Explanation:
Mike from the question exercises primary demand whereby one demands for a class or type of product and not a particular or certain brand that falls under that class. This is broader than selective demand which Lou exercised
Selective demand is the demand for a certain brand of product and maybe in a certain style. This is narrower than primary demand.
Because the witnesses had different viewpoints so they might have seen different things..
If for example the witness is somehow related to the victim, his/her point of view might have been compromised and couldn't be used
hope this helps
The answer to this depends on what sources you are using, but some sources state that people identify lies only 55% of the time!
That's very little, considering that 50% is the chance level - this number would be the one used if we could never really use our intuition to guess correctly. For example if we guessed that every second person randomly lies that would give us the "chance level" of 50 %. (if exactly half of the people lied).
And in real life, we can tell 55% of the time if people are lying - this means we are slightly better than chance.
We can conclude from this that we should never trust our intuition about whether people lie or not!
