11. What did Charles Darwin think about on his journey home to England?
He noticed the many patterns of diversity in most species and how these differences varied from island to island
12. After Charles Darwin returned to England, what hypothesis he develop to explain his findings?
Separate species arose from a common ancestor.
The correct answer is: E) cleavage furrow formation and cytokinesis
Cytochalasin B (cytos-cell and chalasis-relaxation) is a molecule which inhibit network formation by actin filaments by blocking monomer addition. As a result, itshortens actin filaments. This molecule is involved in cytoplasmic division where it blocks the formation of contractile microfilaments. One of the microfilament’s function includes cytokinesis and formation of cleavage furrow so these functions are affected by cytochalasin B.
Answer:
Yes, it is estimated that there are about one trillion microbes species on earth, and we have not been able to isolate 99.99% of them, so, the knowledge is very limited. There is an study approach called METAGENOMICS. In Greek, meta means “transcendent.” It is a research field that allows to study comunities from their total DNA. It is, you can extract and sequence DNA from a sample, and find out about the composition of the population in there, even the interactions between them, with no need of pure culture.
