Answer:
what is the question you basicly just gave us a paragraph to comment on
Explanation:
Answer:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.

Answer:
Taxol induces the assembly of microtubules, while Nocodazole suppresses tubulin assembly
Explanation:
Taxol and nocodazole are antimitotic drugs, i.e., drugs that inhibit the progression through the cell cycle, which is useful for killing cancer cells. Microtubules are proteins that act as the 'skeleton of the cell', which need to be reorganized when cells replicate. These structures (microtubules) are composed of α and β-tubulin heterodimers which assemble into protofilaments of microtubules. Taxol is an antimitotic drug that induces the formation of microtubules, thereby inhibiting microtubules' reorganization during mitosis. In consequence, cells treated with Taxol enter into apoptosis (i.e., programmed cell death). Moreover, Nocodazole is known to induce microtubule disassembly by interfering with the polymerization of tubulin monomers. In consequence, Nocodazole is useful to depolymerize the microtubule cytoskeleton.

See the answer below
Explanation:
<em>It may seem that the options have been omitted in this question. However, in order to evaluate the claim that a mean from a particular group is statistically higher or lower to a mean from another group, there would be a need to compare the two means. </em>
Mean comparison or testing for a significant difference between means can be carried out using the Student's t-test or one-way Analysis of Variance (ANOVA).
When the means being compared are just for 2 groups as indicated in the illustration, Student's t-test and one-way ANOVA can be used. However, once there are more than 2 group means being compared, one-way ANOVA will only be applicable.
