Answer:
Temperatures in a desert climate range from 86 to 104 degrees Fahrenheit, while summers are wet and winters are dry. When the rains fall, herds of prey animals abound as they feed on the lush grasslands and water at the many waterholes and rivers. The average rainfall in the desert is 10 inches per year. Sahara desert vegetation includes African Welwitchsia, date palm, thyme, magaria, olive trees, orange trees, and fig trees. Apart from these, more than half of the Sahara desert is extremely barren with no vegetation found. However, there are still some areas in the Sahara desert that are lush, containing abundant trees and plants. The most common landscape features found in deserts are sand dunes, yardangs, desert pavements, debris, playas, oases, mesas, alluvial fans, arroyos and buttes. These landforms vary from desert to desert. In areas dominated by the tundra climate type, winters are long and cold, especially in the region north of the Artic Circle where, for at least one day in the year, the Sun does not rise. Winter precipitation generally consists of dry snow, with seasonal totals less than in the summer when cyclonic storms that develop along the boundary between the open ocean and sea ice yield rainfall. The average snowfall in the tundra is 10-40 inches per year. Tundra vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone between the tundra and the forest is known as the tree line or timberline. The arctic tundras located between the north pole and the coniferous forests or taigaregion. It is characterized by extremely cold temperatures and land that remains frozen year-round. Arctic tundra occurs in frigid mountaintop regions at very high elevations.
Answer:
D. Burn more oil for heating homes
Explanation:
Encouraging people to conserve power would help weaken the greenhouse effect, not increase it. Stopping cutting down the trees in the Amazon forest would also heavily help weaken the greenhouse and not increase it. And unlike the others, using more nuclear power plants wont affect the greenhouse atfect but instead affect our air quality. Our problem is that burning coal, oil, and gas produces carbon dioxide, which adds to the supply already in the atmosphere, increasing the greenhouse effect and thereby increasing the temperature of the Earth so therefore its D.
Answer:
Divergence
Explanation:
This happens because of the different genetic makeup or genotype of different individuals. The divergence mechanism occurs because of divergent evolution where in some cases random chances occurs and neurons became a source of stimulus for one but not other and vice versa.
The statement “This type of evidence can be checked by others” best explains the importance of empirical evidence in science.
Explanation:
There are all kinds of evidence used in science, but empirical evidence is obtained as a result of <u>repeated experiments and observations</u>. This evidence is used to either support or argue against a scientific theory. Empirical evidence is the preferred evidence since this kind of evidence can be peer reviewed, i.e. reviewed by other scientists and/or researchers. In other words, the experiment can be redone, and the <u>evidence can be tested</u>.
Answer:
they both decrease genetic variation
