Answer:
polyphyletic
Explanation:
Polyphyletic
The organisms in this groups show similar attributes, but lack a recent common ancestor and could have risen from convergence.
Take for instance, birds and mammals in a polyphyletic group of warm-blooded animals may possess a mixture of biochemical and physiological attributes. On the other hand, their most recent common ancestor was a cold-blooded species, which shows birds and mammals had their warm-blooded nature as separate groups.
Another example is the Elephants, hippopotamuses, and rhinoceroses belongs to a polyphyletic groups with each one coming from a separate small species.
Answer:
The sister group for the following are:
a) Eukaryotes
Sister group is Archaea
b) Opisthokonts
Sister group is Amoebazoans
c) Stramenopiles
Sister group is Alveolates
d) Protists
They don't have a sister group
e) Bacteria
Sister group is Archaea
f) Bikonts
Sister group is Unikonts
Explanation:
Sister group is a term used in phylogeny to show the relationship between a group of organisms.
When two species come from a particular group or taxon, they are sister groups to each other.
Protists in the above answer does not have a sister group because most protists are not related to each other. Protists tend to be more related to plants or animals.
Answer:
G
Explanation:
your have to look at the second triplet of bases: AGT since it says the chain is only 2 amino acids long (so the 3rd triplet must be the stop codon).
Now remember that for the DNA-mRNA transcription A becomes U, T becomes A, C becomes G and vice versa. So to codify a UGA codon you need ACT in the DNA. Since we have AGT instead, it means the G was changed by the mutation.
