It represents unusual growth pattern. The normal growth curve is sigmoidal( S - Shaped). This is where the population of an organism rises steadily initially, then rapidly as in exponential growth pattern (J - Shaped); but then declines negatively until at zero growth rate.

Describe three hypotheses proposed to account for the decline in cell numbers during the death phase of a growth curve.

1. Nutrients and O2 deficiency. With cell number increasing competition for substrate increases so nutrients (or oxygen for aerobic bacteria) become less available, number of dying cells arises and the viable...

I'm in need of an explanation for zig-zag or two start model of chromatin packaging. Can you provide some help. Thank you.

"Zig-zag" or "two start" model of chromatin packaging are identical names for spatial structure of 30-nanometer chromatin fiber. According to it, in chromatin DNA is joined with histones (proteins that...

Given the following reaction: Cu+2AgNO3=2Ag+Cu(NO3)2 How many moles of zag will be produced from 46.0 g of Cu, assuming AgNO3 is available in excess?

First, the amount of Cu should be calculated:n = m / Mr,where m - mass, Mr - molecular weight, n - number of moles.n (Cu) = 46 g / 64...

If a is numpy array of shape (5,3) and b is of shape (2,4),what is the shape of a (b)?

Assuming the elements of b are valid indices into rows of a, then a[b] will be a 3D array with shape (2,4,3). In your example, that means b should be...
