You are examining the phylogenic relationship of a newly discovered plant species (Species 2). You amplify the RUBISCO barcode a
frozen [14]

Answer:

a. Inversion

b. Duplication

Explanation:

Inversion has the name suggest, has to do with a segment of DNA being reversed from end to end.

In this case here,

Inversion is taking place here.

species 1 ATGCAAATTTGGGCCCATGAATGGTTGCAA

species 2 ATGCAAAAATTTTGGTACGCCGAATGGTTGCAA

Therefore, the sequences in bold in species 1 are observed to be reversed end to end in species 2.

Deletion ❌❌

I am sure it's not feasible because deletion entails removal of a few sequences.

It can be seen that species 2 is longer than species 1, which gives another reason why deletion is not feasible too, as no sequences are seen to be deleted.

I believe duplication is feasible since AATT sequences are repeated once.

Our final answer,

inversion and duplication occur here.

Water molds are fungus-like and heterotrophic. Why are they classified as chromists rather than protozoans or fungi
Colt1911 [192]

Answer:

The cell wall of oomycetes, however, is not composed of chitin, as in the fungi, but is made up of a mix of cellulosic compounds and glycan. The nuclei within the filaments are diploid, with two sets of genetic information, not haploid as in the fungi.

Hey guys...........please help me with this one❤❤❤❤ Every organism needs food. Does a cell also need it? Explain very briefly.
Alexxx [7]

Cells do need food. In a process known as cellular respiration, cells convert biochemical energy (oxygen as food) from nutrients into adenosine triphosphate (ATP), and then release waste products.


hope this helps.. :D
