Point source pollution is a single, identifiable location of a pollution like a drainage or a pipe. On the other hand non-point source pollution refer to wastes that are disposed at a wide area and cannot be easily determined where the sources are. The answer for this is false. It is the non-point source pollution that is difficult to track and to control.
Answer;
DNA or protein sequences of shared genes
The MOST accurate way to determine the evolutionary relationship between two animals is through the examination of DNA or protein sequences of shared genes.
Explanation;
DNA or protein sequences of shared genes. Biochemical evidence is extremely accurate in determining the relationship between two organisms. Many animals have been re-classified, due to DNA evidence.
78% is nitrogen, 21% is oxygen, 1% is other.
<span>Triglyceride. Triglycerides are organic molecules found in fat cells like the subcutaneous tissues. They are the main constituents of body fat in humans and other animals; they are a type of lipids found in the blood which the body uses for energy in cases of starvation.</span>
Answer:
The animal triglycerides have a higher proportion of saturated fatty acids than the plant triglycerides.
Explanation:
The triglycerides have three fatty acids attached to the single glycerol molecule by ester linkage. The fatty acids may be saturated or unsaturated. The triglycerides with saturated fatty acids such as the animal triglycerides exhibit a relatively tight packing of these fatty acids and make them solid at room temperature.
On the other hand, the triglycerides with unsaturated fatty acids such as the plant triglycerides are liquid at room temperature since the presence of double bonds in the hydrocarbon chains leads to weaker interactions and does not allow the tight packing of the fatty acids.
