Between 2000 and 2013, fatalities from measles decreased by approximately 75%.
<h3>What do you mean by Measles?</h3>
Measles may be defined as an acute and highly contagious viral disease that is commonly caused by a single-stranded RNA virus known as measles virus.
Fatalities caused by measles in 2000 = 582,800
Fatalities caused by measles in 2013 = 145,700
Total differnce = 437100.
Now, the percentage = 437100/582800 ×100 = 75%.
Therefore, between 2000 and 2013, fatalities from measles decreased by approximately 75%.

Answer:
D) Expressed in the stomach, but not in the cells of the small intestine
Explanation:
Answer:
10%
Explanation:
Chargaff postulated the complementary base pairing rule, where he stated that in the DNA molecule, Adenine (A) will always pair with Thymine (T) and Guanine (G) with Cytosine (C) i.e. A-T, G-C
Chargaff stated that the concentration of purines (Adenine and Guanine) is always equal to that of pyrimidines (Thymine and Cytosine) i.e. {A} + {G} = {C} + {T}
These equal concentration equals 100% in totality i.e. A+G+C+T= 100%
Thymine pairs with Adenine, if there is 40% of Thymine in the DNA molecule, it means there will be 40% of Adenine also. 40 + 40 = 80%. This leaves us with 100-80 = 20% for Guanine and Cytosine.
Since there will be an equal amount of Guanine and Cytosine too, Guanine will therefore, be 20/2 = 10%.
That is, 10% Guanine, 10% Cytosine.
The correct option is D.
When it comes to movement of particles in an out of cells, there are two basic types of transportation, these are passive and active transportation. The passive transportation of particles does not require the use of energy while the active transport system requires the use of energy in the form of ATP. From the diagram given in the question, it can be seen that energy is involved in the process. Energy is mainly needed to move the particles against the concentration gradient since the inside of the cell is highly concentrated while the outside has low concentration. <span />
