1. Answer;
Monkey
Explanation;
-Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms.DNA-DNA hybridization, this process hybridizes the genetic information from two different organisms to determine similarities between them.
-In this case the DNA of housefly, bettles , butterfly and grasshopper are very similar as they are closely related organisms.
Therefore; Monkey's DNA would be expected o be least similar to the housefly’s.
2. Answer;
The sample yields very little DNA,
which means that it must be amplified to produce enough quantity to detect on a gel
Explanation;
-Polymerase chain reaction, or PCR, is a technique used to take a piece of DNA and make many copies of it. This technique is very similar to the natural process which cells use to make new copies of DNA, but it is also a little different.
-PCR is a necessary step in the analysis of a DNA sample taken from a crime scene because the sample yields very little DNA, which means that it must be amplified to produce enough quantity to detect on a gel.
Answer:
Light is an essential factor in maintaining plants. The rate of growth and length of time a plant remains active is dependent on the amount of light it receives. Light energy is used in photosynthesis, the plant's most basic process.

Answer:
<h3>When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.</h3>
Answer:
Option (C).
Explanation:
The plasma membrane of the eukaryotes are made of the phospholipid bilayer and the proteins are embedded or span the membrane bilayer. The carbohydrates are attached in moieties with the protein and lipid.
The fluidity of the membrane depends on the saturation, cholestrol and the hydrocarbon chains. The hydrocarbon chain is non polar in nature that allows the diffusion of non polar solutes across the membrane. This decreases the permeability of the polar molecules and the hydrophobic interactions in the membrane.
Thus, the correct answer is option (C).
