Answer: answer
Explanation: Using PCR, a DNA sequence can be amplified millions or billions of times, producing enough DNA copies to be analyzed using other techniques. For instance, the DNA may be visualized by gel electrophoresis, sent for sequencing, or digested with restriction enzymes and cloned into a plasmid.
Answer:
B
Explanation:
The plains have large rivers flowing through them. Every living creature or plant that grows requires water, so the answer is B.
Fertilizers are needed by very large farms. It is what makes it possible to grow enough grain to have excesses to sell.
Pesticides are also needed. Insects abound in many sparsely populated areas.
Renewable resources are used, but it is not the answer.
Answer:
Explain how natural resources are identified:
Satellites are machines that are launched into space. They move around the Earth to get information that can help identify natural resources. How do satellites do this? Satellites scan the Earth’s surface to get information about its color and brightness. This information is used by a computer to make a “computer map”. Once they finish the "computer map" a person would look at the map and determine which materials are which. These maps are not for showing a person how to get from one place to another, but for showing what the surface of Earth looks like and what it is made of.
Why are natural resources unevenly distributed:
The formation of these resources requires certain conditions. For example, copper ores are formed where there is volcanic activity. Iron ores were formed a long time ago when certain substances combined to form sedimentary and other types of rocks. So, iron ores could be found more often in places with environments that were just right for the formation of these rocks. Graphite forms when another type of rock, called metamorphic rock, is formed.

This is what I put and I got all the information from the text on edge 2021.
