Answer:
CFU/mL
Explanation:
Given -
a) Number of colonies of bacteria is equal to ![66](https://tex.z-dn.net/?f=66)
b) Total volume of the solution is equal to
mL
c) Dilution factor is equal to ![10^{-7}](https://tex.z-dn.net/?f=10%5E%7B-7%7D)
As we know that
CFU/mL ![= \frac{N * DF}{V}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7BN%20%2A%20DF%7D%7BV%7D)
Where N is the number of bacterial colonies, DF is the dilution factor and V is the volume
Substituting the given values in above equation, we get -
CFU/mL ![= \frac{66* 10^7}{0.1} \\= 66*10^8](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B66%2A%2010%5E7%7D%7B0.1%7D%20%5C%5C%3D%2066%2A10%5E8)
6) humans
7) bacteria
8) caterpillars & rabbits
9) trout, and predators
10) It can be overfeeded , and everybody will die sooner or later

The actively dividing cells, or meristems, control plant growth. Primary (apical) meristems, the dividing tissue at the tips of the roots, grow longer roots, and secondary meristems, the dividing tissue seen in the cross-sections, grow thicker roots.
