What layer of the atmosphere contains almost 80% of the atmospheres total mass

Biology

Solution:

The troposphere is the atmospheric layer closest to the planet and contains the largest percentage (around 80%) of the mass of the total atmosphere.

The troposphere is the lowest major atmospheric layer, extending from the Earth's surface up to the bottom of the stratosphere. The troposphere is where all of Earth's weather occurs. It contains approximately 80% of the total mass of the atmosphere.

The troposphere is characterized by decreasing temperature with height (at an average rate of 3.5 degrees F per thousand feet, or 6.5 degrees C per kilometer). In contrast, the stratosphere has either constant or slowly increasing temperature with height.

Thus the right answer is troposphere.

Arctic foxes typically have a white coat in the winter. In summer, when there is no snow on the ground, the foxes typically have

arsen [322]

Answer:

The decrease in the amount of daylight in winter causes a change in gene expression, which results in foxes growing a lighter - appearing coat.

Explanation:

With less quantity of sunlight during winter days, the arctic fox is not able to produce melanin, the natural pigment that changes the hair color into brownish color. In summer days, is the opposite effect, in this way, the hair of the fox turns into brown - gray color.

How can DNA be used to illustrate that evolution has occurred?

Alexxandr [17]

DNA can illustrate that evolution has occurred since in the process of natural selection advantegeous genes or traits have been selected to pass on through generations and further more evolve as long as the species survies and is successful in reproducing.

Each sentence describes an interaction between two of Earth’s spheres. Match each sentence with the spheres that are interacting

galina1969 [7]

The answers would be the following:

Geosphere and hydrosphere - water vapor condenses on a glass.

Hydrosphere and biosphere - Grady swims in the ocean.

Biosphere and atmosphere - Lena takes a deep breath

Atmosphere and geosphere - gusty winds weather sandstone in the desert.

If you'd like to know why:

Geosphere involves the solid part of the Earth, so that would mean it involves the rocks, land, and the like.

Hydrosphere involves water, your clue there would be hydro, which means water.

Atmosphere involves the air around us, which includes winds.

Biosphere refers to the biotic components. Bio means life, so we consider living things here.

Now all those spheres interact with each other, and it is through this interactions that our world is formed and how our Earth is able to sustain life.

Taking into consideration the features of each sphere, you can see that Grady is a living organism and the ocean is made up of water.

Hence, hydrosphere and biosphere are interacting.

Lena is a living organism, and she is breathing in air.

Hence, biosphere and atmosphere are interacting.

Water vapor is made up of water, and glass is a solid found on Earth. (Not really a good example of interaction between these two spheres)

Hence, hydrosphere and geosphere are interacting. 

Lastly, gusty winds is part of the atmosphere and sandstone is a type of rock.

Hence, Geosphere and atmosphere are interacting.

Define monohybrid inheritance and law of segregation??

dexar [7]

Answer:

In a monohybrid cross, both the alleles are expressed in the F2 generation without any blending. Thus, the law of segregation is based on the fact that each gamete contains only one allele. This law is based on four basic concepts: A gene exists in more than one form of an allele.
