In this exercise, you will compare the amino acid sequence from the aphid to the amino acid sequences of the other species to id

entify how similar they are. As a first step, you will compare the aphid sequence (Acyrthosiphon) to a bacterial sequence (Pantoea).
The sequences below show the first 60 amino acids of one polypeptide, using the one-letter abbreviations for the amino acids. An underscore (_) indicates a gap inserted in a sequence to optimize its alignment with the corresponding sequence in Arabidopsis.

An amoeba reproduces by splitting itself into two amoebas. This means that the original amoeba dies and its two offspring live o
Naddika [18.5K]

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
