What are the classifications of the animal kingdom?
According to the system set up by Linnaeus, all animals are classified into seven categories: kingdom, phylum, class, order, family, genus and species.
Answer:
volt
Explanation:
The potential difference is expressed in volt (V). The potential difference between two points is said to be 1 volt if the work is done in moving 1-coulomb charge from one point to other is 1 joule. 1 volt= 1 joule/ 1 coulomb Unit for measuring the potential difference is volt and instrument used for measuring potential difference is a voltmeter.
<span>There are multiple possible hypotheses the researchers can test in their experiment. The following seems to be the most logical:
- humidity affects the cycling time in nitrogen cycles
- the inputs of nitrogen are exceeded by the amount of nitrogen re-cycled in a system.
- light availability improves nitrogen acquisition in plants.
- leaf litter removal due to heavy storms will alter nitrogen cycling in plants.</span>
Biomass is the most used renewable source of energy in US in the year of 2009.
<h3><u>
Explanation:</u></h3>
In US, the country is very cold and use of wood and other plant products as chimney fuels, or in cooking and other purposes are very common. This is because being a temperate country, US has forests of conifers which are source of soft wood, ideal for burning.
Other sources of Biomass energy comes from the biogas, wood wastes, ethanol, municipal solid wastes and even biodiesel.
As a present day scenario, although coal and petroleum are still the most used fuels in US, but the use of renewable sources of energy has increased to twice the amount from 2010 to 2018.
