Answer:
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life.

Explanation:
An omega-3 fatty acid is one that has its first double bond at the <u>methyl </u>end of the molecule.
Explanation:
Fatty acids will have a methyl end and a carboxylic acid end and the long carbon chain.
The number of hydrogen atoms attached to the carbon atoms depends upon its saturation type – saturated or unsaturated fatty acid.
The main advantage of the unsaturated fatty acids is that they have fewer hydrogen atoms because they are replaced with a double bond between the carbon atoms.
There are both short chain (carbon atoms 18 or less) or long chain (more than 20) fatty acids.
Omega-3 fatty acids are polyunsaturated fatty acids (PUFA). Depending upon the carbon chain length, the first C=C double bond occurs between the third and fourth carbon atom from its methyl end on the carbon chain of the omega-3 fatty acid.
Omega-3 fatty acids are recommended by dieticians due to its immense health benefits especially for the heart since it reduces blood triglyceride level, blood pressure, plaque formation, and the risk factors for heart attacks or failure. These are also good for the eyes, to treat mental depression, and for fetal brain development during pregnancy.
Answer:
c. individuals of a single species that live and interact in one area
Explanation:
When some organisms belonging to a single species live together in an area, they make a population. Since members of a population belong to the same species, they are able to interbreed among themselves to produce viable and fertile progeny. They have the same resource requirement and interact with each other. All the plants of <em>Mangifera indica</em> present in an area make a population. Likewise, a group of <em>Panthera tigris</em> living in a forest together makes the tiger population of that area.
