Deadly particles like SO2 that comes into contact with the air will form air pollution. This deadly particles will then form acid rain. When those rain comes into contact with water supply, they turn the water acidic. They will cause river to be too acidic for fishes and other living organisms to survive.
The stomata closes down at night when there is no sun and there's no photosynthesis. It also closes down when the air is dry and when it's hot so as to prevent excessive loss of water.
When you encounter a molecule like this, you've encountered a Triglyceride:
Glycerol + Fatty acid + Fatty acid + Fatty acid (1 Glycerol + 3 Fatty acids).
Hope it helped,
Happy study/ study/ exam!
That's correct - it's a square where on one axis, the paternal allele (allele = one of the possible forms of the same gene), and on another the maternal allele is listed. Often, it's also indicated whether an allele is recessive or dominant.
Then, in the table that results, all the possible "combinations" of allele between the paternal and maternal party are created. If you count how often a certain combination appears, it indicates the likelihood of that combination.
See the picture (though it is directly from Wikipedia, please note). The likelihood of BB is 25%, of Bb is 50%, and of bb 25%.
