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.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.

the answer is 100% density i've answered this question before and done the quiz myself.
