Answer:
Lower Salinity in the ocean water.
Explanation:
The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures. Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals.
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
As temperature increases, the space between water molecules increases—also known as density, which therefore decreases. ... Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases
Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.

Answer:
The correct answer is 4.6 percent.
Explanation:
The Oort cloud refers to the clouds of icy objects, which is present in the outermost section of the solar system. These are the disperse layer of clouds found in the external layer of the solar system.
In the given question, it is given that the number of comets in the Oort cloud is 10^12 comets.
The number of comets getting close towards the Sun is 10 comets in a year.
The age of the solar system is 4.6 * 10^9 years
The number of comets used since the start of the solar system is,
(4.6 * 10^9 years) (10 comets/year)
= 46 * 10^9 comets
Thus, the number of comets disappeared since the beginning of the solar system is 46 * 10^9 comets.
The initial number of comets at the start of the solar system is 10^12 comets.
The percentage of comets that are used up are:
(change in no of comets) / (initial no of comets) % = (46 * 10^9 comets) / (10^12 comets) * 100
= 4.6 percent.
Answer:
The correct answer is option B "It will become narrower (span a more narrow range of ambient temperatures)".
Explanation:
Dogs, and other animals with fur, use their pelage to increase the range of ambient temperatures that they can tolerate. The way they do it is by altering their fluffiness depending if they are exposed to cooler or heater temperatures. If a dog is shaved, its thermoneutral zone will become narrower. Therefore, the dog will not be able to live in extremal temperature conditions as it did before with its fur.
