Explanation:
When a scientist uses radiometric dating to determine the age of a rock specimen, would he use a radioactive element with a short half life, say a half-life of less than 10,000 years, or a radioactive element with a long half-life, say a half-life greater than 1 billion years?
Answer:
He will use a radioactive element with a long half life of greater than 1 billion years
Explanation:
Rocks are an aggregation of solid mass which is usually rich in minerals. The age of rocks is established using radiometric dating method.
According to Oxford Dictionary, radiometric dating is "a method of dating geological specimens by determining the relative proportions of particular radioactive isotopes present in a sample."
The age of rocks can only be ascertained using isotopes that have very long half lives because many of these rocks are very old (aged billions of years) hence their age can only be determined using elements that has a half life greater than 1 billion years.

if earth suddenly had no moon, which biome would begin to change immediately and change most?
Answer:
The ocean.
Explanation:
A chemist wants to show how the molecular structures of the major greenhouse-effect contributors allow them to
absorb heat.
Which of the following would the chemist not be modeling?
A) carbon dioxide
B) carbon monoxide
C) chlorofluorocarbons
D) nitrous oxide
E) methane gas
Answer:
Option C is the correct choice
Explanation:
The major contributor of green house effect are
a) Carbon dioxide (CO2)
b) Carbon Mono-oxide (CO)
c) Nitrous oxide
d) Methane
e) Ozone
The chlorofluorocarbons (CFCs) is a man made green house gas and hence the chemist will not model it as it does not allow to absorb heat. Instead it leads to non ending chain reactions with the ozone layer thereby degrading it and hence allow entry of harmful UV rays.
Option C is the correct choice

Explanation:
why are owls considered keystone predator
Explanation:
Keystone species are animals that help manage other animal species by controlling population numbers and biodiversity within an ecosystem. The impacts of keystone species are usually greater than their numbers.
owls can be a great benefit to places where rodent populations are high. Dense urban areas often suffer from an abundance of rats and mice spreading disease, and rural agricultural communities have their crops consumed and soil eroded from burrowing voles and field mice. Without owls, and other top predators, rodent populations could explode and exacerbate the effects they produce.
Answer:
the owl is a keystone species, as many other birds. and it gives them the nutrients they need when they eat the bird and it mangeges the population of the other species:)
