1- Reactants (H = 2, O = 2)
Products (H = 2, O = 0)
2- Reactants (P = 4, O = 2)
Products (P = 2, O = 3)
So basically if it was H20, then there is 2 Hydrogen because the two is in front of the H and there isn’t a 2 in front of Oxygen.
However if it was H2O2, then there is two hydrogen and two oxygen because there is a two on both of the symbols which indicates how much reactants/products there is.
Hope this helps!
Explanation:
Gram staining is a widely used technique designed to distinguish between the bacteria on the basis of the composition of the cell wall of the bacteria.
The basis of differentiation is the color of the bacteria they attain after staining technique is performed that is gram-positive bacteria remain deep blue in color while gram-negative bacteria appear pinkish-red in color.
If the culture of the bacteria on which the test to be performed is of more age that is more than 24 hours of age then the bacteria cells lose their ability to retain the stain mainly the gram-positive bacteria. Also, the culture gets damaged after 24 hours.
Thus, fresh cultures are used for staining.

Answer:
This is because the neutrality of polarity can be changed by electric field in this case. When you create - charge in the comb and you expose the pieces of confetti to the electric field created by the charge, you will polarise them so that the part closer to the comb will be + and the other will be
Answer:

b: 1/2
c: 1/4
d: 0
Explanation:
Since the wife had a color-blind father (X^cY), she should be a carrier for the disease. Her genotype would be "X^cX". Fathers do not transmit the X-linked disorders to their sons, so the genotype of the husband is "XY".
a. The probability that the couple's first child will be a normal son: 1/4
b. The probability that the couple's first child will be a normal daughter: 1/2
c. The probability that the couple's first child will be a color-blind son: 1/4
d. The probability that the couple's first child will be a color-blind daughter: Zero
