Why do scientists consider vestigial structures (like a human appendix) evidence for evolution?
qaws [65]

Answer:

vestigial structures are considered evidence because scientists believe they are structures that were once used by a species ancestors but are not longer needed. these structures do not impair the organism in any way, so there is no need for evolution to get rid of them. for example, the human appendix is considered a vestigial structure.

(d) State the null hypothesis for the experiment whose data are graphed in Figure 2. Provide evidence to support or refute the s
Varvara68 [4.7K]

The null hypothesis here is "the insertion of the wild type MSH2 gene does NOT reduce the number of <em>C. neoformans </em>C3 and C6 cells". This hypothesis is not supported by Figure 2, thereby the alternative hypothesis is accepted.

In the scientific method, a null hypothesis is a plausible explanation that states that there is no statistically significant difference between a certain feature and/or variable of a particular population.

In this case, the null hypothesis indicates that there are no differences associated with the insertion of the wild-type MSH2 gene variant (i.e., the normal allele) in the growth rate of <em>C. neoformans</em> strains on a medium containing a toxic chemical (mutagenic agent).

Figure 2 does not support the null hypothesis because the growth of wild-type MSH2 gene inserted <em>C. neoformans</em> C3 and C6 strains is inhibited when they grow on a medium containing a toxic chemical, thereby this hypothesis is rejected and the alternative hypothesis is accepted.

Polymers of polysaccharides are all synthesized from monomers by which process? *
Fynjy0 [20]
The reaction which connects monomers (polymerization) is dehydration synthesis.
The name tells you about the nature of the reaction - dehydration means 'loss of water', correct? When two biological monomers connect, one gives up a hydrogen ion (H+), and the other gives up a hydroxyl group; (OH-). They combine to form H2O - water.
