Answer:
The correct answer is "cell lysis due to the effect of osmotic pressure".
Explanation:
The cell wall is a structure that brings protection from the outside world and also helps to maintain the cell's water balance. The cell wall prevents that the cells is exposed to a large amount of turgor pressure, making the cell turgid when it is under extremal conditions. Some antimicrobials, such as bacitracin, block cell wall synthesis which makes the cell unable to support turgor pressure, resulting in cell lysis due to the effect of osmotic pressure.
<span>Ptyalin hydrolysis does not continue in the stomach because it is destroyed by the stomach once it enter the stomach. </span>
Ptyalin is an amylase enzyme commonly found in the saliva of
humans and animals. This enzyme is secreted in the mouth ( buccal cavity) and catalyze
the hydrolysis of starch into maltose and dextrin. Immediately the starch
leaves the mouth and enter the stomach, stomach acids destroy the ptyalin.
Julie listed out fossil fuels are a non-renewable source of energy and Fossil fuels are becoming more expensive.
Option C
<h3><u>Explanation:</u></h3>
Fossil fuels are defined as the type of non renewable energy which is formed as a result of dead and decaying organic matter over thousands of years under pressure and temperature of Earth’s core.
This type of fuels are formed due to the dumping of dead prehistoric organisms like dinosaur and others under the soil under a tremendous pressure and very high temperature, where they are acted upon by bacteria and other chemicals to reduce them into petroleum and coal. These are totally non renewable and they are getting expensive over days due to shortage of availability.
Transfer of newly created plasmids to e coli. The bacteria that contains a plasmid with antibiotic resistance will grow in the presence of antibiotic concludes that the insertion was successful.
<h3>
<u>Explanation:</u></h3>
The plasmid DNA that contains the foreign DNA when integrated with the competent bacteria which is e coli and heated, plasmid DNA will be entering into the bacteria by means of some smaller pores that are created in the membranes of the cell.
The plasmid DNA will be copied many times with the help of the replicating mechanism of DNA of the bacteria. Bacteria will grow on a nutrient rich food called agar after the transformation process. Those bacteria that contains a plasmid containing antibiotic resistance only grow in the antibiotic presence. Transformed bacteria will then grow in larger quantity.
