Answer:
The correct answer is - option c.
Explanation:
Benedict test is used to test the presence of reducing sugar in a sample. If the benedict solution turns in red or orange color it means there is a presence of glucose as it is a reducing sugar. So, this test result shows that there no reducing sugar in the sample as it is blue.
Lugol test is the test to see if the sample has starch in it or no by turning in to blue color, in this result, it is orange in color which suggests that there is no starch available.
A Biuret solution is used to test for the availability of protein in a particular sample, purple or pink color is the representation of the presence of protein. There is no protein as per result
Sudan red test is used to test the presence of TGA, lipids, or lipoproteins in a sample by reacting with it and turn in to red color. The absence of the lipids shows no change as it is shown in this test.
Thus, the correct answer among these options is - option C.
One of the difference is that fishes have single circulation but humans have double circulation of blood.
The answer is Pharyngeal Phase and Esophageal Phase stages of swallowing. In the pharyngeal phase, the bolus of food is pushed against the epiglottis, which closes the respiratory tract. The upper oesophageal sphincter relaxes and the bolus moves into the esophagus. In the oesophageal phase, the oesophageal sphincter closes when the bolus moves down and peristalsis action takes over to move the food down the oesophagus.
First, let's define the alleles:
(Dominant) allele for unattached earlobes is E
Allele for attached earlobs is e
(Dominant) allele for dark hair is H
Allele for light hair is h
Heterozygous would mean that for both sets of alleles, they will be EeHh.
Now for a Punnett Square:
EH Eh eH eh
EH EEHH EEHh EeHH EeHh
Eh EEHh EEhh EeHh Eehh
eH EeHH EeHh eeHH eeHh
eh EeHh Eehh eeHh eehh
These are all the possibilities for the parents' offspring. Since the square is 4x4, then the number of genotypes is <u>16</u>.
<u>Now for the probabilities of each genotype</u> (the amount of times a certain genotype appears divided by the total number of genotypes):
EEHH: 
EEHh: 
EEhh:
EeHH:
EeHh: 
Eehh:
eeHH:
eeHh:
eehh:
(If you ever want to check if your probabilities are off, just add them together and they should add up to the total!)
Hope this helps! :)
