Answer:

The answer to the question: A fossil is determined through radioactive dating to be 1.5 million years old. This is an example of, would be: A: Absolute dating.

Explanation:

In paleontology, there are two ways in which fossils can be dated. One, is the inaccurate one, called relative dating, in which other sources, most commonly rocks around the fossil, as well as other fossils called index fossils, are used to approximately date a target fossil. But the more accurate, and almost infalible one, is called, absolute dating. This one uses radioactive isotopes and their characteristics in rocks and in the fossil itself, to more accurately establish the age of the fossils. The technique measures these isotopes in the minerals and components in the rocks and fossils to determine date.

Which of the following best describes the pattern of microbial death? Which of the following best describes the pattern of micro
____ [38]

Answer:

The cells in a population die at a constant rate

Explanation:

Microbial death is the loss of the ability of microbes to reproduce and survive in an environment. When a given microbial population is given a treatment, the microbial cells die at a constant rate. Microbial death rate  is not dependent on the specie and nor on the antimicrobial agent.

Therefore, the microbial cells in a population does not die at once but die at a constant logarithmic rate; the cells decreases exponentially as nutrients decreases and waste product increases.

For example, if 500,000 microbes are treated or in a nutrient depleted environment and 50,000 microbes is left after 1 minute, by the next minute under the same condition 5,000 microbial cells will be left and this pattern will continue, this explains exponential decrease
