The type of reaction that occurred when potassium chloride and silver acetate react to produce silver chloride and potassium acetate is called a double replacement.
First, write out all combinations for the parents:
<u>SsBB</u>:
SB
sB
SB
sB
<u>ssBb</u>:
sB
sb
sB
sb
So now that you know what to put on as the x and y for the Punnett Square, set it up:
<u> | SB | sB | SB | sB </u>
<u>sB | SsBB | ssBB | SsBB | ssBB </u>
<u>sb | SsBb | ssBb | SsBb | ssBb </u>
<u>sB | SsBB | ssBB | SsBB | ssBB </u>
<u>sb | SsBb | ssBb | SsBb | ssBb </u>
Now, listing each possible genotype and the number of times they show up in the square:
SSBB
0 times
SSBb/SSbB
0 times
SSbb
0 times
SsBB/sSBB
4 times
SsBb/SsbB/sSBb/sSbB/
4 times
Ssbb/sSbb
0 times
ssBB
4 times
ssBb/ssbB
4 times
ssbb
0 times
Since there are only 4 genotypes are possible, set up ratios of those four:
SsBB:
4 times/16 total = .25 = 25%
SsBb:
4 times/16 total = .25 = 25%
ssBB:
4 times/16 total = .25 = 25%
ssBb:
4 times/16 total = .25 = 25%
This means that the<em> genotypes</em> have a 25% : 25% : 25% : 25% likelihood.
Now, let's figure out the phenotypes of the 4 genotypes:
SsBB:
Ss = dominant
BB = dominant
SsBb:
Ss = dominant
BB = dominant
ssBB:
ss = recessive
BB = dominant
ssBb:
ss = recessive
Bb = dominant
So we have 2/4 that are S-dominant B-dominant and 2/4 that are S-recessive B-dominant.
This means that the phenotypes are:
2/4 = 50% Thin stripes with black eyes, and
2/4 = 50% Thin stripes with gray eyes.
I hope this helped you out :)
<span>Autotrophs are green plants which have the ability to manufacture their own foods. They do this by trapping the energy from the sun by the help of a chemical called chlorophyll, which is found in their leaves. The plants combine carbon dioxide and water in the presence of sunlight to produce glucose. The animals, which are heterotrophs and can not produce their own food depend on autotrophs for food. Thus, the autotrophs are usually described as the primary producers in any ecosystem.</span>
The answer is mass and volume.
Oxygen is produced in the light stage of photosynthesis at Photosystem 2 and results from the splitting of water. Chlorophyll does not absorb green light so in green light there will be less water split and so less oxygen is produced.so thats how we know the reason why a leaf is the color that it is. basically it is because of chlorophyll.
Hope this helps.
