Answer:

Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell's ribosomal RNAs (rRNA), the cell's membrane lipid structure, and its sensitivity to antibiotics.

What latitudes experience the<br> coolest temperatures?
Elanso [62]

Answer:

you should expect, on an annual basis the high latitudes (60 to 90 degrees N/S) are the coldest.

Explanation:

Latitude provides the location of a place north or south of the equator and is expressed by angular measurements ranging from 0° at the equator to 90° at the poles. Different latitudes on Earth receive different amounts of sunlight, and are a key factor in determining a region’s climate. For example, the higher the latitude of a given place (the farther away it is from the equator), the sharper the angle of the sun’s rays that reach it, meaning that the rays of the sun are spread across a broader area. Therefore, higher latitudes receive less heat than lower latitude areas nearer the equator.

The Earth’s axis is tilted 23.5° to the perpendicular, meaning that the amount of sunlight that a particular latitude receives changes with the seasons. From April to September, the Northern Hemisphere is tilted toward the Sun, where it receives more energy; the Southern Hemisphere receives this additional energy between October and March, when it is tilted toward the Sun.

Although there is no specific ‘type’ of climate, there are three general climate zones: arctic, temperate, and tropic.

Arctic

From 66.5N to the North Pole is the Arctic; from 66.5S to the South Pole is the Antarctic. Places within the arctic climate zones tend to be snow- or ice-covered year-round. This is despite the fact that they tend also to be exceptionally dry, sometimes receiving as little precipitation as the world’s driest deserts. Very little snow falls on these high-latitude regions, but even less melts due to the cold temperatures and scarce sunlight. The deep ice and snow that covers these regions has been built up over hundreds, indeed thousands, of years. In these regions, the Sun hovers above the horizon at midnight in the summer and never rises at all at times during the winter.

Temperate

The temperate zone is located between the arctic and tropic zones. However, ‘temperate climate’ is something of a misnomer since most regions located within the temperate climate zones experience distinct changes across four seasons. For example, in much of eastern North America – from the Ohio Valley in the United States to the southern shores of Hudson Bay in Canada – the ‘temperate’ climate can experience both arctic and tropical weather in the same year. These climate variations increase the further an area is from an ocean or another large body of water; they diminish in areas where oceans and other large bodies of water are able to influence the climate more strongly. Temperate regions are also affected by the direction of the air flow they receive. Areas in Canada, for example, have cool Arctic air passing through, while the southern United States receives warm air from the Gulf Stream.

Tropic

The tropical belt of land and sea extending around the globe on both sides of the equator – between 23.5S and 23.5N – receives the most sunlight, but it is not necessarily the hottest since it is covered extensively by oceans that use some solar energy for evaporation. This combination of high moisture and intensive solar heating results in a persistent zone of convection (the upward movement of moist, unstable air) known as a tropical low, which often results in generous cloud formation and frequent rainfall. These factors also help moderate the temperatures within this zone.

Most areas, however, are characterized by distinct sub-climates where average temperatures, precipitation, and other factors vary noticeably. Although there are different classifications of world climates, many of these sub-climates include low latitude tropical rainforest and tropical savanna; middle latitude maritime, mediterranean, and steppe; high latitude subarctic, tundra, and polar ice cap; as well as desert and highland areas.

The correct answer for the question that is being presented above is this one: "<span>c. water storage." </span><span>Water storage is one of the following adaptations would be found in a savanna plant, but not necessarily in a grassland plant. This is because savannas may lack water and whenever there is available water (e.g. rain) the plants needs to store it for future usage.</span>

Why dose Canada have such a low population density
Nataly [62]
A large part of that land area is not conducive to farming or general use.  The Canadian Shield covers about a third of the nation.  The Arctic permafrost probably covers another third.  You cannot farm in either of these areas and the cost of building roads and infrastructure in or through these areas is very high.  Other areas have land that could be used for farming but the season is too short.  On the lands that are arable, Canadians are reasonably densely populated.  

<span>As to softened immigration process, the percentage of permanent residents (generally recent immigrants) has remained fairly steady at less than or at 1% of the population for at least 50 years.  Since the birthrates for multi generational Canadians (Canadians whose grand parents or before were immigrants) is so low, Canada needs immigrants to maintain the population at a sustainable level.  Yet the processes have not gotten easier.  The most recent iteration of the Immigration act has extended the time required for a landed immigrant to live in Canada before being eligible for citizenship (from three years in five to four years in six).</span>
