Answer:
D
Explanation:
Linoleic acid is an omega-6 fatty acid that is composed of an 18 carbon chain polymer. Most of the bonds are single bonds but few are double bonds. The double bonds form ‘kinks’ (bends) in the chains. The more the C=C bonds the more bendy the molecule. Nonetheless, it is significant to note that single (sigma) bonds are easy to rotate around their axis than double and triple (pi) bonds. The more the single bonds, the more flexibility the the molecule.
The answer is c... c ... c....
The water in freshwater ecosystems like lakes, ponds, creeks, and rivers are more likely to freeze over in winter because it doesn't contain salt. The salt dissolved in marine environments prevents the water from freezing.

1. Humans should worry about atmospheric changes as they can affect their health in the sense of their lungs and other important body organs being damaged.
2. Positive effect of humans on ozone layer:
The fact that humas have stopped using CFCs has helped the ozone layer as these had a bad effect on this layer protecting us.
Negative effect:
One thing causing a bad effect on the ozone layer is carbon dioxide and the fact that humans are using it very often it causes the ozone layer to decrease in size meaning that the ozone layer won't be capable to protect us from harmful gases.
4. Scientists think that we should try stop the amount of carbon dioxide from rising because the increase in carbon dioxide leads to the earth becoming warmer and this can lead to a drastic change in the climate.
