Answer:
equivalent resistance = R1R2/R1+R2
= 30/13 ohm
V = IR
= 5×30/13
V = 150/13 ohm
Answer:
The answer is B.
Explanation:
Regarding the situation explained in the question that "African Americans are not affected by the malaria disease because of a specific genetic trait that they possess and that trait provides them with protection" can be explained by the answer given in option B.
Being heterozygous, meaning possessing a dominant and a recessive allele regarding that genetic trait, in terms of sickle cell trait which is a gene that causes the individual's blood cells to be sickle shaped and balanced polymorphism which means carrying two different versions of a gene is an argument that is enough to prove that the above statement is incorrect because it means they have blood cells that can be affected by the malaria disease.

The aim of a tax on a valuable resource, in this case residential water use, is to reduce wasteful practices. In this case the county is considering a special tax when residential water use is ABOVE a certain amount. This is an effective mechanism to reduce wastage by causing high users to incur more cost. Everyone will still pay for their water consumption in the normal way (typically by a $/unit cost), however the tax will take effect when the residential water consumption reaches a certain point. This penalises high users of water by forcing them to pay more for a valuable resource. Note that essential services like energy and water are often subsidised in society. This means that we do not pay the true cost associated with the use of the resource. Setting a tax that applies to those that consume over a certain threshold helps to reduce wastage of an undervalued essential resource such as water or energy.
