False. Strontium 90 has a half life of only 30 years, and as millions of years pass, about the time fossils have been around, most if not all of any strontium would have decayed.
Answer:
<em>Yes, the above terms will be much similar.</em>
Explanation:
The term 'closest evolutionary relationship' reflects the organism or species which were the closest to different species in a phylogeny.
Most common ancestor also describes the ancestor from which two different organisms might have evolved.
Both the terms 'closest evolutionary relationship' and 'most common ancestor' show the common ancestors in a phylogenetic lineage. Hence, on evolutionary levels, both these terms have similar meanings and are often used to describe phylogenetic lineages.
Vacuoles store the materials needed for the cell.
The correct answer is Manganese (Mn).
<span>Manganese functions as a cofactor for a large variety of enzymes with many functions including those active in gluconeogenesis. <span>Pyruvate carboxylase that catalyzes breakdown of pyruvate to oxaloacetate requires manganese (or magnesium) for its function. Phosphoenolpyruvate carboxykinase also needs Mn.</span></span>
