Fatty acids are building blocks of lipids. The correct option is A.
Fats and oil are known as lipids.
Lipids are part of the classes of food which are made up of high proportion of carbon and hydrogen with very little oxygen.
Fats are solids and oils are liquids at room temperature. They serve the following functions to the body:
- They provide the body with energy
- They are solvents for fat-soluble vitamins and hormones.
Before lipids can be absorbed into the body, they must be broken down into fatty acids and glycerol.
Therefore, fatty acids are building blocks of lipids.

Gene mutations can be positive, negative, or neutral. Suppose that the normal gene in Model 2 produced a polypeptide that was necessary for cellular respiration.
A) Choose a mutation from those in Model 2 that might be positive for a cell. Explain your reasoning by relating the mutation to the cellular respiration process.
Genes encoded in our DNA result in the production of proteins that perform specific functions within human's cells and various environmental factors and spontaneous events can lead to changes in genes, these changes are called mutations, can lead to alterations in the structure and activity of the proteins in the cells use. Mutations are the source of all new alleles in nature and arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Therefore,a gene mutation is a change in the sequence of nucleotides that occurs during cell replication (mitosis and meiosis) within a single coding section of DNA. Variations in alleles lead to variations in organisms within a population, cellular respiration, i.e. the reduction of inspired oxygen to water, which powers cell function, also generates highly reactive oxygen species that can damage DNA, with the purine bases G and A being particularly susceptible to this kind of attack,so Positive mutations lead to the organism having a better chance of survival, which means the mutation may be passed on to the offspring.
B) Choose a mutation from those in Model 2 that might be negative for a cell. Explain your reasoning by relating the mutation to the cellular respiration process.
Due to one's metabolism, the human body replaces every cell within the cellular respiration process and any mistakes can also occur in the transcription of mRNA or the translation of a polypeptide. However, these changes are considered to be negative mutations, because they are not permanent changes to the cell, however such mutations may lead to an early death probably before the organism can produce offspring.
I believe it goes 8,1,2,3,4,7,5,6 hope this helps
<span />
Answer:
a, d, c, b
Explanation:
I'm not sure how to explain but ik its right!! If not i'm so sorry.
<span>The function of the digestive system is to digest and absorb the food that we eat . Which means that we have two main processes , digestion and absorption. Digestion is the breakdown of food into small molecules,which are then absorbed in your body (during the process of absorption). </span>
