Answer:
D. Clear-cutting would increase the amount of carbon dioxide found in the atmosphere
Explanation:
Plants including trees are organisms that help maintain the balance of carbon in the carbon cycle. They do this via the process of PHOTOSYNTHESIS, which is the way they obtain their energy and carbon source. During photosynthesis, trees (plants) absorb carbon in form of atmospheric carbon dioxide (CO2) from the air through the STOMATA on their leaves.
CO2 is an input substance in order for photosynthesis to occur. In a case where all the trees (plants) of a forest has been clear cut or removed, there will be no organisms to directly absorb the carbon dioxide (CO2) released into the atmosphere via respiration. Hence, the amount of carbon dioxide found in the atmosphere would increase.
Three ways that humans have cut and frayed the woven tapestry of earths
biodiversity:
1.
Landscaping.
By landscaping, living things such as trees are eliminated to make way for the
construction of buildings. And thus, disrupting the ecosystem.
2.
Adding cement
to the ocean to increase the land surface area by excavating soil from the
maintains.
3.
Cutting of
trees.
Answer:
There are no options in this question but generally a sample of DNA can be increased;
By using Polymerase Chain Reaction (PCR) technique.
Explanation:
This question describes the application of making molecular biology to solving a crime problem; a branch called forensics. In this case where an insufficient small amount of DNA sample was recovered from the blood in a crime scene, the polymerase chain reaction technique, commonly known as PCR can be used to increase the DNA sample.
In the 1980's, a molecular technique used to amplify part of a template DNA strand to produce several copies of it, was invented by Kary Mullis and his colleagues. This amplification refers to the numerical increase in the number of DNA sequence.
