The three sources of energy include,

Solar energy

Wind energy

Water and geothermal.

Energy is termed as the capacity of physical system to do work. It exists as kinetic or mechanical energy, light potential energy, electrical and heat.

Source of energy can be classified as renewable and non-renewable.

The renewable is derived from natural processes which replenished constantly, for example, solar energy, biomass, ocean, hydropower and wind.

The solar energy it is sustainable to mean that it does not run out but it is maintained reason being that sun shines every day.

A good advantage of solar is that it is natural and available in plenty, and non-pollution. Wind energy helps to turn the blades of windmills as it turns shaft to where they are attached.

Winds blowing over the Earth's surface blow from ______ pressure centers to the ________ pressure centers.

artcher [175]

Answer:

High, Low

Explanation:

Wind blows air on the surface of the earth from a high pressure center to a low pressure center (this is depicted in the image attached). The area between the two "centers" is referred to as pressure gradient. The warm air in the region of the low pressure center then rises up into the atmosphere. The warm air then cools up in the atmosphere and then passed down back to the earth's surface

Artyom0805 [142]

1. $p^{2} +2pq+q^{2} =1$ where in a population:

p - the frequency of the A allele

q - the frequency of the a allele

$p^{2}$ - the frequency of the AA homozygous genotype

$q^{2}$ - the frequency of the aa homozygous genotype

2pq - the frequency of the Aa heterozygous genotype

A population at equilibrium will have the sum of all the alleles at the locus equal to 1.

2. Conditions:

A. The breeding population must be large

B. No natural selection

C. The mating must occur randomly

D. No mutations to cause changes in allelic frequency.

E. No changes in allelic frequency due to immigration or emigration.

3. By comparing the actual genetic structure of a population with what we would expect from a Hardy-Weinberg equilibrium, we can determine how much it deviates from the baseline provided by the mathematical model. Depending on how large the deviation is, one or more of the model's assumptions are being violated. Thus, we can attempt to determine which one.

How does energy flow in an ecosystem

irakobra [83]

Answer:

Energy is passed from organisms at one trophic level or energy level to organisms in the next trophic level. Producers are always the first trophic level, herbivores the second, the carnivores that eat herbivores the third, and so on.
