C. according to Earth's existing magnetic field.
Answer:
A)11,460 years
Explanation:half of a radioactive element represent the time take for half of it's components to dissociate or disintegrate.
For carbonn14 that undergo an emmision to form a stable carbon 14,it moves thus
14C(1 part) ______14C(0.5 parts)_____14C(0.25parts)
i.e it undergo two radioactive decay which means two half lives .
Since each half life is 5780 years ,the age will be 2×half lives= 2×5780=11,460 years
I'd draw a car on a hill and explain how you press the gas pedal and gravity helps push the car down the hill, or draw it going up the hill and explain how gravity makes it difficult for the car to make it up the hill.
(C) its genetic diversity is very low.
<h3>What is meaning of Extinction?</h3>
Extinction is the final phase of a sort of creature or a taxon—typically a species. Although the ability to reproduce and bounce back may have been lost earlier, the death of the last member of the species is typically considered to be the moment of extinction.
Determining this point is challenging because a species' potential range may be quite wide, and is typically done after the fact. Due to this problem, there are phenomena like Lazarus taxa, in which a species that was thought to be extinct suddenly "reappears" after a period of apparent absence (usually in the fossil record). Estimates place the number of extinct species at over five billion, or more than 99% of all species that have ever existed on Earth.

The main dietary factor associated with elevated blood cholesterol is saturated fat.
<h3>
What about saturated fat?</h3>
- Because they increase the amount of LDL cholesterol in our blood, saturated fats, sometimes known as "bad fats," increase the risk of cardiovascular disorders (including heart disease and stroke).
- Cholesterol that is circulated in the blood.
- The majority of this cholesterol is produced by the body, however some is also absorbed from the meals you eat.
- Even if they include fat, foods derived from plants never contain cholesterol.
- Only foods from animals do. Low density lipoproteins are able to transport cholesterol.
- Dietary fat, particularly saturated and trans fats, may increase LDL and total cholesterol levels in the blood.
- Blood cholesterol levels may be lowered by substituting polyunsaturated and monounsaturated fats, particularly olive and canola oil, for some saturated fats.
- When we consume too much saturated fat, the receptors stop functioning as effectively, and blood cholesterol levels rise.
