Branching points at the root of the eukaryotic phylogenetic treeA) suggest that Archaeplastids were the first eukaryotesB) are presently unclearC) strongly suggest that fungi are more closely related to plants than animalsD) reveal that unikonts are derived from the SAR clade

B) are presently unclear.

Explanation:

Any group of organisms whose cells contain a mitochondrion and a nucleus is referred to as the Eukaryote.

Branching points at the root of the eukaryotic phylogenetic tree are presently unclear.

Haven studied the root of the eukaryotes over the years, the branching points at the root is still not clear and unresolved.

However, the first eukaryote may have been capable of phagocytosis.

materials water oxygen those are the things i can think of in this moment.

the answer will be a) proteins i believe
