Answer:
The folded structure at that region of the primary sequence of a protein that contains proline will have an alpha helix at that .
Explanation:
Amino acids that feature a side chain with a cyclic ring system are known as aromatic amino acids.
Histidine, as well as proline,as well as proline, are two well known examples of aromatic amino acids.
These side chains of such amino acids used to make a protein determine the shape of the protein.
Alpha helices were created at that site when proline was present in the amino acid's main sequence.
As a result, an alpha helix would indeed be present within the folded structure of such a proline-containing protein's main sequence.
Amino acids' primary purpose is to act as that of the components that make up proteins. About Fifty to 2,000 amino acids are normally linked end to end in several configurations to form proteins. Each protein contains a different set of amino acid sequences that are folded and bent in a certain way.

Antibiotic resistance genes in bacteria can be transferred by ______ gene transfer.
Horizontal
Antibiotic resistance genes in bacteria can be transferred by horizontal gene transfer.
What is horizontal gene transfer?The dissemination of antibiotic resistance genes among bacteria (aside from those that are passed from parent to child) is a result of horizontal gene transfer (HGT), which also promotes the evolution of pathogens.How do genes for antibiotic resistance function?Once a bacteria has acquired a resistance gene and incorporated it into its DNA, the bacterium can dominate other bacteria and convey the resistance gene to all of its offspring. Bacteria reproduce quickly, which amplifies resistance.What three kinds of horizontal gene transfer do bacteria engage in?Bacteria can transfer genes horizontally through transformation, transduction, and conjugation. Conjugation is the most prevalent method of horizontal gene transfer among bacteria, particularly from one donor bacterial species to another.Give an example for horizontal gene transfer?In multicellular organisms, horizontal gene transfer can happen in a number of different ways. For instance, in plants, HGT can function naturally through host-parasite interactions.

Why it is that proline is considered to disrupt a helix but histidine does not?
Proline can disrupt the helix while histidine cannot because of their difference in side-chain structures.
Proline is different from all the other amino acids as it contains a secondary amine rather than the amino group. The side chain of the proline forms a cyclic structure among itself, thereby creating stearic hindrance. Thus, making it unsuitable for the alpha-helix. This is why proline acts as a helix breaker.
Histidine is a positively charged amino acid with an imidazole functional group. Unlike proline, the side chain of histidine does not form a cyclic structure in itself and hence it does not act as a helix breaker.

What would happen to both acid-fast and non acid-fast cells if no heat was used in the staining procedure?
When both acid-fast and non-acid-fast cells if no heat was used in the staining procedure the cell wall becomes hydrophobic and impermeable. It happens because most stains and chemicals in aqueous material are in the absence of heat due to the waxy, destructive structure. It's possible that we neglected to heat the solution or decolored it excessively.
Acid fast stains are used to differentiate acid-fast organisms such as mycobacteria. Mycolic acids make up a large portion of the cell walls of acid-fast bacteria. Nonacid-fast bacteria will stain blue/green with the Kinyoun stain, while acid-fast bacteria will stain red. Non-acid fast bacteria are those that decolorize and lose their carbol fuchsin red color.
The primary difference between acid-fast and nonacid-fast bacteria is that acid-fast bacteria resist decolorizing by acid after receiving a stain whereas non-acid-fast bacteria are readily decolorized by acid after staining.

Nonrenewable resources are used much more prevalently today despite knowing that they pollute and will run out in the future. why then are we not using more renewable resources?
We are not using more renewable resources because we have been using fossil fuels since the 18th century and renewable resources are comparatively new. Also, we have limited knowledge about them, so it will take time to change our mindset toward renewable resources.
Based on exhaustibility, there are mainly two types of resources, renewable resources, and non-renewable resources.
Renewable resources are those resources that are replenished while non-renewable resources are those resources that are not replenished.
The non-renewable resources take millions of years to form and once exhausted they cannot be made more.
Examples of renewable resources are solar energy, wind energy, geothermal energy, etc. while examples of non-renewable resources are fossil fuels like coal and petroleum, metals, etc.
Despite the fact that the supply of non-renewable resources like coal and petroleum is limited and they also cause pollution, the use of them is rampant around the world.
The use of fossil fuels is widespread because we have been using them since the 18th century and the use of renewable resources is a very recent phenomenon.
Also, a major hurdle for using renewable resources is the upgrading of current technology to harness these resources.
