Margarine is a butter substitute that is solid at room temperature. It is made from vegetable oils (often soybean or canola oil)

. The label on a container of margarine lists "hydrogenated vegetable oil" as the major ingredient. Which statement below makes sense?
a) The hydrogenated vegetable oil is less likely to clog arteries compared to butter.
b) The hydrogenated vegetable oil stays solid at room temperature because the fatty acid chains have been saturated with hydrogens, breaking the double bonds between carbons.
c) The hydrogenated vegetable oil has more "kinks" in the fatty acid chains, compared to non-hydrogenated oil,causing it to be solid at room temperature.
d) The hydrogenated vegetable oil has a lower melting point.

Answer:

The correct answer is: b).

Explanation:

  • Oil or solid fat is composed of long chains made up of hydrocarbons (fatty acids).
  • The fatty acid can be:
  1. Saturated - in which all the carbon atoms in the long hydrocarbon chain are linked to each other by single bonds. As a result of this there is a tight packing between the fatty acid molecules which gives them a solid texture at room temperature.
  2. Unsaturated - in which there are one or more double or triple bonds in between carbon atoms in the long hydrocarbon chain. As a result of this kinks or bends develop in the fatty acid chain which results in generation of space or gap in between fatty acid chains. This gives the fatty acid the capability to move as a result of which they have a liquid texture at room temperature.
  • Hydrogenation is a process by which the unsaturated fatty acids (oil) are converted to saturated fatty acid (margarine) by reducing the multiple bonds in between the carbon atoms with hydrogen.
  • Hydrogenated oil has a higher melting point and so it is solid at room temperature.
  • Hydrogenated oil can also cause clogging in the arteries as they cannot be easily broken down due to their increased stability.

Why do viruses need hosts to reproduce
Olin [163]
When it comes into contact with a host cell, a virus can insert its genetic material into its host, literally taking over the host's functions. An infected cell produces more viral protein and genetic material instead of its usual products. Some viruses may remain dormant inside host cells for long periods, causing no obvious change in their host cells (a stage known as the lysogenic phase). But when a dormant virus is stimulated, it enters the lytic phase: new viruses are formed, self-assemble, and burst out of the host cell, killing the cell and going on to infect other cells. The diagram below at right shows a virus that attacks bacteria, known as the lambda bacteriophage, which measures roughly 200 nanometers

What biological macromolecule is made up of monomers like the one shown below? Answer Carbohydrate Fat Nucleic acid Protein
LekaFEV [45]

Answer;

-Nuclei acid

Explanation;

-Nucleic acids are molecules that allow organisms to transfer genetic information from one generation to the next. These macromolecules store the genetic information that determines traits and makes protein synthesis possible.

-Nucleic acids include DNA and RNA. These molecules are composed of long strands of nucleotides. Nucleotides are composed of a nitrogenous base, a five-carbon sugar, and a phosphate group.

Which of the following are ways that DNA can undergo mutation? A. During DNA replication, the wrong base is added to the strand
trasher [3.6K]

Answer: Option C.

High-energy waves like UV light or radiation physically damage the DNA

Explanation:

Mutation is the change or alteration that occur in the DNA sequence or nucleotides sequence of an organism which is caused by mistakes when the organism is copied or environmental factors such as UV light.

Ultraviolet light cause mutations by activating the SOS repair systemof which is a part of i a new DNA polymerase that has no power to edit e but has the ability to move past the thymine dimer and synthesize DNA, This lead to cells able to replicate but with a high frequency of mutations.
