A great amount of Antarctic animals feed on them. Whales, penguins, fish, birds, etc. They eat phytoplankton.
1.) B it is not d because it shows a growth in the beak size, it didn't say anything about the birds having larger beaks just that the size increased
2.) A
p=.5 q=.5
q^2=.25 p^2= .25 2(pq)= .5 everything added up is 1.0 so we good
so q^2, which is the recessive gene or gg, is 25 percent
The<em> cell membrane</em> controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.
The correct answer is (a) driving.
The pressence of undesirable substances in air is called as air pollution. There are many human activities that contribute to air pollution. The biggest contributor is driving. The pollutants that comes out of the car are carbon dioxide, carbon monoxide. They also release hydrocarbon and nitrogen oxides which when combines in sunlight becomes ozone. Air pollutants emitted by cars and other automobiles increases the level of harmful gases which to severe health problems such as heart disease, asthma, irritation in eyes.
Answer: the low air pressure reducing CO2 solubility
The differences between the airplane and standard cruising altitude are air pressure. When you are on the higher ground, the air pressure should be lower since there is less air above your head.
In a place with less air pressure, the gas solubility will decrease. Bubbles appeared if gas solubility is lower than the gas concentration. Assuming the beverage concentration is same, then it will be much more bubble appeared in an airplane because the gas solubility is lower.
