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.

Describe the lysogenic cycle. Write a paragraph. Please don't copy and paste answers. Thank you.
Answer:
The viral DNA is inserted into the DNA of the host during the lysogenic cycle; however, viral genes are not expressed. During each cell division, the prophet is transmitted to daughter cells. The prophet leaves bacterial DNA after some time and passes through the lytic cycle to create more viruses. hope this helps 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

What is the name given to your gag reflux organ?
Answer: pharyngeal reflex
Explanation:
The gag reflex, also known as the pharyngeal reflex, is when your pharynx contracts and your larynx pushes up, contracting your throat.
The afferent limb of the reflex is supplied by the glossopharyngeal nerve (cranial nerve IX), which inputs to the nucleus solitarius and the spinal trigeminal nucleus. The efferent limb is supplied by the vagus nerve (cranial nerve X) from the nucleus ambiguus.

Sucrose is a carbohydrate produced naturally in plants. It is composed of glucose and fructose. Carbohydrates are made by plants which derive their food resources from photosynthesis. What molecules used in photosynthesis are rearranged to produce carbohydrates? Choose ALL that apply. A)ATP B)water (H2O) C)oxygen (O2) D)methane (CH4) E)carbon dioxide (CO2)
Answer:
b,e
Explanation:
i just took it
Carbon dioxide (CO2) and water (H20) are the molecules used in photosynthesis and rearranged to produce carbohydrates.
WHAT IS PHOTOSYNTHESIS:
Photosynthesis is the process by which green plants manufacture their food (glucose) using energy captured from sunlight. Photosynthesis involves series of biochemical reactions, however, the carbon dioxide and water are the two molecules combined. The general equation is represented as follows:6CO2 + 6H2O → C6H12O6 + 6O2
Therefore, carbon dioxide (CO2) and water (H20) are the molecules used in photosynthesis and rearranged to produce carbohydrates.
