I know that he found finches in different areas with different beak shapes....he found this was caused by the type of seeds that were available on the different islands...over time (evolution) their beaks changed to allow them to be able to survive (survival of the fittest)
<span>Answer:
Think of DNA-there are only 4 bases, but different combinations give infinite possibilities.
And the same for amino acids and proteins.
Immunoglobulins work on a similar principle. Different VDJ segments are combined for the heavy chain of an antibody. Different VJ segments are combined for the light chain.
Other ways:
Random nucleotides may be added or removed between the gene segments.
There are also different combinations of light and heavy chains.
Antibodies can be any of the 5 isotypes: IgA, IgM, IgG, IgE, IgD.
I'm not going to go into detail as this answer would take too long to write. Do some literature searching on B cells, V(D)J recombination, RAG genes, class switching.</span>
The following facts apply about Jupiter;
It is the largest planet (in the solar system) – 13,000 times bigger than earth
It has retrograde motion. However, the retrograde motion is actually an illusion due to the fact that the earth catches up with Jupiter planet during the revolution around the sun.
Ozone is present in the stratosphere layer of earth's atmosphere, which is about 6 to 30 miles from the earth's surface.
It is very helpful as it protects the life on earth from the harmful ultraviolet rays that come from the sun.
It is harmful as well because when it is inhaled by humans it can damage the lungs and can cause various problems such as chest pain and respiratory diseases.
The ozone layer is depleted by the CFCs, as the UV rays of the sun breaks down the CFCs into chlorine atoms. These chlorine atoms react with ozone and deplete the ozone layer.
Answer:
1. grow
2. Stimuli
Explanation:
the first sentence talking about getting bigger = grow and the second sentence talking about swimming = Stimuli doesn't make sense if you say. swimming is grow and the other VS
