In cell b2 same cost may or may not appear based on the value in cell a2 (if value changes in a2, then this cost is multiplied with the difference of value in cell (a2-a1), otherwise value of previous cell appears in cell b2.
Each mature Volvox colony is composed of numerous flagellate cells similar to Chlamydomonas, up to 50,000 in total, and embedded in the surface of a hollow sphere or coenobium containing an extracellular matrix made of a gelatinous glycoprotein.olvox is a polyphyletic genus of chlorophyte green algae in the family Volvocaceae.
In microbiology, a colony-forming unit (CFU) is a unit used to estimate the number of viable bacteria or fungal cells in a sample.Viable is defined as the ability to multiply via binary fission under the controlled conditions.stimation of microbial numbers by CFU will, in most cases, undercount the number of living cells present in a sample for these reasons. This is because the counting of CFU assumes that every colony is separate and founded by a single viable microbial cell.
