What observations are consistent with the conclusion that DNA serves as the genetic material in eukaryotes? Select the four corr
11111nata11111 [884]

Answer:DNA is shown to be the genetic material in bacteria and some phages.

DNA is shown to be present in mitochondria, chloroplasts and nucleus, where genetic function is performed

Specific genes can be isolated and spliced into bacterial DNA, which can be inserted into a bacterial cell, and then its genetic expression is monitored.

DNA and RNA are found to be the only macromolecules in eukaryotes that consist of a set of subunits which can combine in unique sequence

Explanation:

1. Lipds is another macro molecule with different subnits  of  fatty acids and glycerol,therefore the option ( DNA is found to be the only macro molecule in Eukaryotas that has different sub units) is WRONG.

2 The   correlation of action and absorption spectra varies with different organisms DNA. e..g  in viral cells  there is a wide difference between the absorption and action spectra, that is no correlation, while  some bacterial cells showed correlations. The option(For DNA, content in various cell types action and absorption spectra of ultraviolet light are correlated IS WRONG.

What a vestigial structure? How does it support evolution?
atroni [7]
A vestigial structure is a structure that kind-of just "hangs out" in our bodies. We don't really need it, yet it is there. So, why is it there??? We probably needed it, for example, when we needed to digest plants. (Appendix) Some say that the appendix was used for digesting plants and berries, but it is really just speculation. We "evolved" to not need the appendix. 
Here are some other vestigial examples: wisdom teeth, tail bone, pelvic bone in a snake, and wings on a flightless bird. 
I hope this helped, if it did not let me know!!
I hope you have a fantastical day!!!XD
