Answer:

D. Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.

Explanation:

Radioactive dating is the method in which radioactive isotopes are employed to evaluate the age of rocks and ores. There are many complex radioisotopes utilized for radioactive dating is like Potassium, Uranium, and Carbon. Radioactive dating operates on the system that a radioactive isotope can fade into the constant daughter nuclei at a steady rate. Geologist commonly uses the system for half life. Half-life is the time needed for half of the radioactive element to decline. This is fixed for a selective element.

Spontaneous reactions _____. always result in increased disorder of the system always take place at a rapid rate always release
Dmitry_Shevchenko [17]
The correct answer is that it "naturally favor the formation of products".
Spontaneous Reactions is best described as a response that favors the formation of merchandise on the situations under which the reaction is happening. A roaring bonfire is an instance of a spontaneous reaction, for the reason that it is considered to be exothermic (there may be a decrease in the energy of the system as strength is launched to the environment as warmness).

Why the horses developed an oxygen debt when they exercised.
user100 [1]

Answer:

The horses developed an oxygen debt when they exercise because they suffered from Exercise-Induced Pulmonary Hemorrhage (EIPH).

Explanation:

A temporary shortage of oxygen in the body tissues during physical exertion such as exercise or a sudden burst of activity is referred to as oxygen shortage.

Horses (compared to humans) are uniquely designed to experience little or none of this.

When the body takes up oxygen, it reacts with glucose to produce energy. This is called Aerobic respiration.

There is also another procedure that the body uses to produce energy. This occurs when glucose is broken down in the cells. After this happens, lactic acid is created but cannot be stored in the body and must be expelled.

This interval when energy is produced without the presence of oxygen is called "oxygen debt".

When a horse is fit, its breathing quickly returns to normal. The longer the time taken for the breathing to return to normal, the less fit the horse is.

One of the factors that can reduce the fitness of a horse is the Exercise-Induced Pulmonary Hemorrhage (EIPH).

This occurs when blood vessle in the lung ruptures causing blood to bleed into the airways. So blood occupies space where oxygen should have. This reduced the amount of oxygen delivered to the blood stream. Hence the oxygen debt takes longer to be repaid.

Cheers

Why do most stars not necessarily die in the time we would normally expect them to?
Ivanshal [37]
The reason why stars does not die when it is there time is because they tend to fuse in different and more heavier elements. In that way, it prevents them from dying for they were able to have the components of different elements, extending their lives and prevent themselves from dying on the time that they were supposed to.
