Oil, natural gas, and coal are all fossil fuels.
A. Biodiesel is man made.
Hope this helps. :)
Following general conditions are necessary for natural selection to occur in population:
- More organisms are born than can survive.
- Organisms vary in their characteristics, even within a species.
- Differences in reproduction and survival are due to variation among organisms.
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Galapagos Finches: The Galapagos finches studied by Darwin on his famous voyage are probably the most common example of natural selection.
A. endoskeleton
Endoskeleton is not a characteristic of Arthropods that has attributed to their diversity and success. Endoskeleton is defined as inner characteristics of the skeletal feature of an organisms such as bears, humans, fish and etc.
Exoskeleton on the other hand is the trait by which arthropods posses. It is skeletal feature that is described outside or is extrinsic, this is evident as crabs have their skeletons outside of their body.
Sanitary landfill burial technology could help to reduce the amount of
waste going into a landfill
Explanation:
The land which is carefully designed into the top of the ground where trash is easily isolated. The main purpose of landfill is to keep It dry and care try to not come in contact with air. It is not like a compost pile.
This method is introduced by England in 1912. It is also called controlled tipping. It is about 1- or 3-meter feet. It is covered with clay.
<span>The ecosystem is the lowest level of the biosphere hierarchy to include weather patterns and soil conditions.
in the whole biosphere hierarchy, ecosystem actually placed as the second highest (1 place below biosphere)
But there are only 2 hierarchy that include weather and soils, and those hierarchies are biosphere and ecosystem. So technically the ecosystem will be the lowest in this matter</span>
