Answer:
The Earth's geosphere is divided into three chemical sections: The crust, composed almost entirely of light elements, like silicon. The mantle, which is 68% of the Earth's mass. The core, the innermost layer; it is composed of very dense elements, such as nickel and iron.
Explanation:
In Geosphere is the solid or mineral part of the Earth, consists of layers, from the outer crust down to the inner core, which have separated through density and temperature.
Grasshoppers are an important native component of grassland ecosystems in the U.S., playing a role in nutrient cycling and serving as a critical food supply for wildlife.
Answer: Option (c) is the correct answer.
Explanation:
A long hydrocarbon chain that consists a terminal carboxylic group is known as a fatty acid.
An unsaturated fatty acid consists a double bond within the fatty acid chain. If a fatty acid contains more than one double bond then it is known as polyunsaturated fatty acid.
For example, oelic acid has chemical formula 
is an unsaturated fatty acid.
Therefore, we can conclude that option (c) represents an unsaturated fatty acid.
Generally, you can calculate it with this formula: df = (r-1)(c-1) where r is the number of rows and c is the number of columns.
Answer:
A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts or human activities such as specicide and human population planning.
