Step-by-step explanation:
Larval mosquitoes breath through trachea in their siphons. This is a structure analogous to the snorkel on a diesel electric submarine. It allows for gas exchange with the atmosphere while the remainder of the insect is submerged. The opening of the siphon is hydrophobic so it won’t get wet and blocked by water. This works well to keep the siphon and the trachea open under normal conditions. Oil when poured on water forms a thin film. When there are mosquitos in that water, when their siphons contact the oil layer, the oil wets and blocks their siphons and suffocates the mosquitoes. This works against most, but not all mossies, as evolution is an amazing process. Some mosquitoes (Mansonia, Coquilletidia) have a siphon designed to penetrate the air vessels in aquatic plants and they don’t need to come to the surface to breath like other mossies. So oil won’t work on these genera.
Answer:
the answer is a 20% increase
Step-by-step explanation:
first, you have to find the amount of change (how much her points scored increased
second , you would divide 
which equals 0.2
then you would multiply by 100 or move the decimal two places to the right
which would equal 20%
Answer:
5y = 18
Step-by-step explanation:
Answer:
Y=x+6
Step-by-step explanation:
to find out the slope you use the equation y2-y1/x2-x1. When you plug in the coordinates it will look like 7-2/1-(-4) and this is equal to 5/5 which can be simplified to 1. So the slope is 1! Now to find the y intercept you have to do b=y1-m*x1! If you plug into the coordinate it will be b=2−(1)⋅(−4) which is equal to 6. Then to construct out equation of the line it will be y=mx+b so now we plug in the slope and the y intercept so that the equation would be y=x+6
