Answer:
composition of meteorites
Explanation:
The continental drift theory has been based upon several evidence. The shape and perfect fit of South America and Africa is one of those evidence. The fossil records are another very strong evidence, as there are fossils of the same species on different continents that are not connected to each other in the present, and in nature is practically impossible to have the same species in different continents. The evidence about the climate also suggests that the continents have been moving, as there are remains of glaciers at places that nowadays are deserts and savannas. The meteorites are not one of the evidence though, and their composition doesn't have anything to offer in this tehory, as their composition is not related to the Earth and the processes on it.
Answer:
The temperate rain forest.
Explanation:
Temperate rain forests are similar in structure and precipitation amounts to a tropical rain forest. The difference is in the location and temperature of each. Tropical rain forests are located on and near the equator, and are incredibly warm and humid, with large amounts of precipitation. Temperate rain forests are found north of the Tropic of Cancer and have moderate temperature and humidity levels. The way to remember the difference is to notice that Temperate is a combination of 'moderate' and 'temperature' and can be said to mean "moderate temperature".

Answer:
A: Oxygen levels are low and, therefore, more red blood cells are produced, giving the athletes an advantage when competing at lower altitudes.
Explanation:
<em>At high altitudes, the partial pressure of oxygen is lower compared to lower altitudes</em>. The body system try to adjust to lower oxygen level by undergoing several physiological changes. Depending on the duration spent in high altitude, the body can either try to adjust in the short term or acclimatize for a longer term.
One of the processes the body undergoes during acclimatization is an increase in red blood cell production. The kidney secretes erythropotein in response to inadequate oxygen in body tissues, and this makes the liver to increase erythrocyte production.
The increase in red blood cell production correspondingly increases the oxygen-carrying capacity of the blood as a result of increased hemoglobin. This condition persists for a few weeks even after the body returns to lower altitude where oxygen is adequate. Increased oxygen capacity means the rate of energy production (through respiration) within the body will also increase
<em>Hence, those who acclimatize to high altitude usually experience increased capillary density, tissue perfusion and improved athletic performance at lower altitudes. </em>
The correct option is A.
