Answer:
Sunlight hits a smaller surface area at the Equator so heats up quickly compared to the poles. Explanation:
The

Monosaccharides are also known as Simple sugars.
Two main categories of sugars are monosaccharides and
disaccharides. Fructose, glucose, and ribose are included
in monosaccharides. Glucose is a kind of sugar in monosaccharides that is known
as the blood sugar.</span>

The only statement on the options that says true about density is:
> The density of an object determines whether it will sink or float.
Why?
Density is a physical property of an object.
Density is not derived as a unit of measure. It is derived from 2 fundamental units: kg and m.
The Density of an object is not constant.
Density is calculated by dividing the mass by the volume of an object.
Answer:
Most food webs have between 4 and 5 trophic levels
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers only absorb 0.1 or 1%.
From the input of solar energy begins a unidirectional energy flow. It passes through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is eventually dissipated in the environment.
There is an energy transfer from each trophic level to the next, and each level only uses 10% of this energy. This assessment is called "The 10% rule". As a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. The rest of the energy is used by the organisms in their own metabolism or dissipated as heat to the environment.
The progressive reduction of energy determines the number of trophic levels, which, in general, turns to be between 4 and 5.
Answer:
Gravity is considered to be one of the universal forces inherent of nature itself. Gravity is an attractive force between objects, which is proportional to the mass of the objects and inversely proportional to the distance between them. Gravity is what help planets follow an elliptical orbit, and is the reason why we can keep our feet on the surface of the earth.
