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
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.

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:)

Read the following passage from the Biology Department at University of California, Berkeley.
Northern elephant seals have reduced genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely.
Which of the following best describes how the population has evolved?
The population has not evolved because there was no change in allele frequencies.
The population has not evolved because it has grown.
The population has evolved because it has grown.
The population has evolved because there was a change in allele frequencies.
Answer:
the last one sorry if i'm wrong
Explanation:
According to the passage from the Biology Department at University of California, Berkeley.Northern elephant seals have reduced genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely.
The best option that describes is" the population has not evolved because there was no change in allele frequencies.Thus, option B is correct.
What is population?The term population reffered to the total number of people living in a particular given area.The population of an organism can't survive if it exceeds it's carrying capacity.
The causes that affect population growth animals that if there are more plants than usual in area, populations of animals that eat that plant may increase.
If animal population increases the population that eat that animal might also increase.
The effects of animals population can be dangerous and when population exceed the carrying capacity of their environment, animal suffer of malnutrition and disease.
When predictors became scarce due to over population, the weekar species of animal start or die in other ways .
The accurate description of the growth of a natural animal population is limited by environmental factors.
Therefore,The best option that describes is" the population has not evolved because there was no change in allele frequencies.Thus, option B is correct.
