Question

This phylogenic tree is composed based on molecular data (rRNA). What statements can we infer are true about the organisms throughout the tree?

options:

Because the tree is rooted, all branches share a common ancestor.

All organisms have some sort of cellular structure/organization.

All Eukaryotes evolved from Bacteria.

Since the organisms contain RNA, they share the same DNA.

If the organisms contain RNA, the share the same four nitrogen bases.

Answer 1

Because the tree is rooted, all branches share a common ancestor.

All organisms have some sort of cellular structure/organization.

If the organisms contain RNA, they share the same four nitrogen bases.

Answer 2

Because the tree is rooted, all branches share a common ancestor.

All organisms have some sort of cellular structure/organization.

If the organisms contain RNA, they share the same four nitrogen bases.

Step-by-step explanation:

The tree is rooted means that they are sharing common ancestor of all the species which are present in the phylogenetic tree, it shows the evolutionary relationships between the groups of species.

The level of organization is found in an organism that is organized from the small form to the large form such as organelle form cells, cells form tissues, tissues form organs, etc.

If the organisms contain RNA, they share the same four nitrogen bases because RNA contains these 4 nitrogenous bases: Adenine, Cytosine, Uracil, and Guanine.
