Answer:

Proterozoic Eon

Explanation:

The Proterozoic Eon is the most appropriate eon to indicate the geological age of this rock unit. This is because this rock presents fossils of the first multicellular and soft-bodied marine organisms and it was in the Eon Proterozoic that the first single-celled living organisms appeared.

The Proterozoic eon, as already mentioned above, is characterized by being the period of the land where the first multicellular marine organisms appeared. This period is divided into three ages: Paleoproterozoic Era (where eukaryotic beings arose), Mesoproterozoic Era and Neoproterozoic Era (where the first multicellular marine organisms arose).

sladkih [1.3K]

Answer:

A. maintenance of axons is not a cellular activity associated with microtubules.

Explanation:

Microtubules are hollow, bead-like, tiny tubular structure that helps cells maintain its shapes. Together with microfilaments and intermediate filaments, they form part of the cell's cytoskeleton. Microtubules also contributes to the cell movement or cytokinesis that includes muscle contractions in muscle cells. Microtubules also replicated chromosomes to opposite ends of a cell during cell division. Microtubules also contribute to the parts of the cell that help it move and are structural elements of cilia, centrioles and flagella. A bundle of microtubules makes up an axonemal structure of cilia and flagella.
