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

In hemoglobin, the transition from t state to r state (low to high affinity) is triggered by:_________

Elena L [17]

In hemoglobin, the transition from t state to r state (low to high affinity) is triggered by Bisphosphoglycerate (BPG)

Bisphosphoglycerate (BPG), also known as 2,3-Disphosphoglycerate (2,3-DPG), aids in the transition of hemoglobin from a high-oxygen-affinity to a low-oxygen-affinity state.
2,3-BPG binds to hemoglobin, causing oxygen to be unloaded. Furthermore, 2,3-BPG reduces hemoglobin's affinity for oxygen. As hemoglobin is unloaded in our tissues, 2,3-BPG binds to it, promoting oxygen unloading.
When we increase the concentration of 2,3-BPG in our blood, the oxygen binding curve shifts to the right. This means hemoglobin will have a lower affinity for oxygen and will be able to deliver more oxygen to our body's tissues and cells.
