Genetic variation can be defined as the difference in the DNA sequences between the individuals in the population
<u>Explanation:</u>
- Antibiotic resistance in bacterial populations is caused by natural selection of bacteria that inherit mutations that make them resistant to the antibiotics,this sentence describes the source and preservation of genetic variation.
- The Mutation is one of the genetic variation or disorder, and probably bacteria choose mutation to become repellent to antibiotics
- In some of the cases of spontaneous bacteria have been obtained from other sets of bacteria through the process and make the bacteria repellent to an antibiotic.
- They survive antibiotic treatment and increase in numbers by natural selection.
- Natural selection can be stated as the process in which organism survive and reproduce adapting to the environment
It should be the trophic level..
<h2>Collagen genes is the best choice</h2>
Explanation:
Collagen is the most abundant protein in mammals
- Collagen is found in bones,muscles,tendons and skin
- It is the one which holds the body together
- It strengthen and support many tissues in the body
- Collagen genes encode many types of collagen which have a structural role in the extracellular matrix and has a great tensile strength
- At least 26 different collagen polypeptide chains are present which are encoded by 26 unique collagen genes
- Since collagen is the main protein of connective tissue in animals and is considered as the most abundant protein in mammals it can be the best choice to base the phylogeny
- Rest all options are specific for a particular function in particular animals
Ham and turkey belong to the macromolecules of proteins, oil and vinegar belong to the macromolecules of fats and oil, while wheat bread belong to the macromolecules of carbohydrates.
<h3>What are macromolecule nutrients?</h3>
The macromolecule nutrients are those nutrients that are made up of large organic molecules which are usually proteins, carbohydrates, fats and oil.
The macromolecule category that each food item belong to include the following:
- Ham and turkey belong to the macromolecules of proteins,
- oil and vinegar belong to the macromolecules of fats and oil,
- while wheat bread belong to the macromolecules of carbohydrates.
The monomer unit that each food item must be broken down into to perform cellular processes include the following:
- Ham and turkey: must be broken down into amino acids.
- Oil and vinegar: must be broken down to triglycerides.
- Wheat bread: Must be broken down to glucose.

Answer:
<h2>The Infusion Nurses Society (INS) classifies a solution as isotonic if its tonicity falls within (or near) the normal range for blood serum-between 280 and 300 mOsm/liter. A hypotonic solution has an osmolarity less than 280 mOsm/liter, and a hypertonic solution has an osmolarity greater than 300 mOsm/liter.</h2>
