B. Absolute dating uses the half-life of an element
Absolute dating is a technique that uses radioactive minerals present in rocks and fossils while relative dating compare the sample in terms of age difference. However, absolute dating is more accurate because it uses half-life of an element and provides dates in years.
Answer;
2) the rate at which changes occur in a type of molecule
Explanation;
The molecular clock is figurative term for a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged.
Scientists can use relaxed-clock methods to deal with variation in the rate of the molecular clock. By measuring the patterns of evolutionary rate variation among organisms, they can also gain valuable insight into the biological processes that determine how quickly the molecular clock ticks.
A B
Archaebacteria kingdom of unicellular prokaryotes whose cell walls do not contain peptidoglycan
Protista kingdom composed of Eukaryotes that are not classified as plants, animals, or fungi
Fungi kingdom composed of heterotrophs; many obtain energy and nutrients from dead organic matter
They would cut down trees which when cut down release. This would then affect the air quality as trees absorb the carbon dioxide in the air. It is also destroying animals habitat
