Answer:

If one amoeba dies then two amoeba get born:

at different stages of the generations of the amoeba it changes accordingly and the died amoeba numbers are also change in the given manner :

          stages    dies                          born

          I               1                                2

          II              2^{1}           4 = 2^{2}

          III              2^{2}          8 = 2^{3}

At  n^{th} =  2^{n}    2^{n+1}

By the geometric series formula:

 1+a^{1}+ a^{2}+ a^{3}...+ a^{n}=\frac{a^{n+1} }{a^-1} }

so,  1+2^{1}+ 2^{2}+ 2^{3}...+ 2^{n}=\frac{2^{n+1} }{2^-1} }

Thus, total amoeba died = 2^{n+1}-1

        total amoeba died+1 = 2^{n+1} (born).... hence prooved

What happen to the brain and the brain cavity?
Gnoma [55]

Answer: OK so The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).Survival in untreated hydrocephalus is poor. Approximately, 50% of the affected patients die before three years of age and approximately 80% die before reaching adulthood. Treatment markedly improves the outcome for hydrocephalus not associated with tumors, with 89% and 95% survival in two case studies

Maintenance of extracellular water volume on the other hand depends primarily on the extracellular concentration of sodium and chloride ions.
