The condition called dysuria is characterized by painful or difficult urination, it can be due to pathologic or benign causes.
Mimicry. Mimicry the close resemblance of 1 plant or animal
to another for some purpose. mimicry is a similarity of one organism, usually
an animal, to another that has evolved because the resemblance is selectively
favoured by the behaviour of a shared signal receiver that can respond to
both.[1] Mimicry may evolve between different species, or between individuals
of the same species. Often, mimicry evolves to protect a species from
predators, making it an antipredator adaptation.[2] The resemblances that
evolve in mimicry can be in appearance, behaviour, sound or scent.
Answer:
6400 years
Explanation:
Given that;
N/No =(1/2)^t/t1/2
No = amount of radioactive material originally present
N = amount of radioactive material present at time t
t= time taken for N amount of radioactive material to remain
t1/2 = have life of the radioactive material
2.5/40 = (1/2)^t/1600
1/16 = (1/2)^t/1600
(1/2)^4 = (1/2)^t/1600
4 = t/1600
t = 4 * 1600
t = 6400 years
Solar energy or fuel does little to pollute the earth's atmosphere.
