The correct answer is polar cell.
Polar cell is termed as the transport of heat to polar latitudes from tropical to be accomplished.
Examples of cells which are found in the hemisphere include ferrel cells, polar cells, and Hadley cells.
Convection cell is termed as a phenomenon which is known to occur when there is a difference of density in the body of gas or liquid.
The difference occurs when there is rising and falling of currents. Any fluid from conventional cell can be formed. For example in the earth atmosphere.
Answer and Explanation:
The gene pool is the sum of all the alleles in a population. Sometimes, allele frequencies within a population change randomly with no advantage to the population over existing allele frequencies. This phenomenon is called genetic drift.
Answer:
You have 20% of adenine. If you have 20% of adenine than you have 20% of thymine, because the amount of adenine and thymine is equal. 20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%. Then divide this by 2 and you will get 30%. 30% of guanine and 30% of cytosine, because their amounts are equal in the DNA stand.
Explanation:
Answer:
D (proteins moving ions from low to high concentration across a cell membrane)
Explanation:
Active transport, by definition, is a type of substance transport that requires energy (typically in the form of ATP). Having said that, we can immediately eliminate B (aka water diffusion throughout the cytoplasm of a cell), as diffusion (osmosis in this case) does not require any expenditure/spending of energy. Next, we can cancel A and C because although they do require energy, there is no transport involved. Thus that leaves us with D. D is not only the answer because of the process of elimination but also b/c the ans. choice says that ions are being moved from low to high concentration, which is against the concentration gradient and thus requires energy.

50/50
you see, the coin only has 2 sides
Also, you're flipping it twice
therefore, the probability is matched up and you have a 50/50 chance of getting heads at least 1 of those 2 times
(Hope it helped ^_^)
