According to the diagram of the water cycle, what happens to the water in the oceans before it becomes water in the atmosphere?
OverLord2011 [107]
<span>Within the water cycle, the water within the ocean evaporates and is converted into a gaseous form before it is able to enter the atmosphere (Answer A). High in the atmosphere, the water then cools and condenses, forming water clouds that eventually rain back to the ground and ocean. </span>

How does crossing over in meiosis result in genetic variation?
Aneli [31]

Cross over is the first  way genes are shuffled to give rise to genetic diversity. Cross over takes place in sexual  reproduction.  The normal way that cross over occurs is chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other.

If they break the pieces at the same locus in the sequence of base pairs, the result is an exchange of genes called  genetic recombination and it ensures that the daughter cells produced  have a different genetic makeup from the parent cell and thus diversity occurs.

Dr. Haxton says the o-o bond is polar and the c-c bond is nonpolar. A good student would say ...
Serggg [28]

Dr. Haxton says the O-O bond is polar and the C-C bond is nonpolar. A good student would say ...

a.No, both bonds are highly polar.

b.Yes. O attracts electrons more strongly than C.

c.Right! O is electronegative, so O2 is polar.

d.Wrong again, Ralph. Both bonds are nonpolar. When two atoms of the same kind form a covalent bond, they share electrons equally because their electronegativity is the same.

e.No way. C is more electronegative than O.

Answer: d.Wrong again, Ralph. Both bonds are nonpolar. When two atoms of the same kind form a covalent bond, they share electrons equally because their electronegativity is the same.

Explanation:

Often when O and H are present in the substance at (opposite) ends (of the electronegativity scale), the polarity observed is very large, we can safely say the substance have a polar bond in it.

Which organisms are not examples of an adaptive radiation?
gavmur [86]

Answer:

Option B, Mammals and reptiles in the post-dinosaur age.

Explanation:

Adaptive radiation is mechanism through which species evolve very fast from common single ancestors. In simple words two different species are said to have evolved through adaptive radiation when they have descended from a single lineage. This is not the case with mammals and reptiles.  

Generally in adaptive radiation, a species evolve when it faces new environmental challenges due to change of habitat or area. For example mammals have evolved from dinosaurs.  

Hence, option B is correct
