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.
Answer:
B. an asteroid belt lies between them.
Explanation:
The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets.
The Darwin's theory of evolution states that the organisms evolve through the process of the natural selection of the favorable genetic variations gradually over time. Through this process of the evolution, new species are developed over time. A single population may give rise to different species. These newly evolved species share similarities will each other as they have the same ancestor.
Hence, the given statement is 'true'.
Answer:
No
Explanation:
The results of the phenotype do not make any sense in relation to the main aim of the experiment.
Smooth, wrinkled, yellow, green describe attributes relating to seed texture and flower colours in a result that simulates that of a plant breeding experiment, rather than a plant physiology experiment.
The determination of the effects of carbon dioxide deficiency in the soil on the phenotypes of peas is a physiological experiment. Hence, a result in the form of a plant breeding experiment would make not be relevant.
