Given that,
The speed of a wave, v = 200 m/s
Wavelength, 
We need to find the frequency of this wave. The relation between wavelength, frequency and the speed is given by :
So, the frequency of this wave is 100 Hz.
The smallest type of stream is a brook.
Out of the following given choices;
A) naturally acquired passive immunity; will have
B) artificially acquired passive immunity; will not have
C) artificially acquired passive immunity; will have
D) naturally acquired active immunity; will have
E) naturally acquired active immunity; will not have
The answer is B. It is
artificially acquired because it is introduced into the body and not naturally produced
by the immune system. Passive immunity <span>because
it involves immunoglobulins that are part of passive immunity of the acquired
immune system. Will not have long-term
memory passive immunity does involve T and B cells that are mainly involved in
memory of immunity. </span>
<span>this is because
gene mutation. Albinism is a recessive trait caused by a mutation in the gene for the enzyme which is important in melanin synthesis. </span>
