The penicillin will kill the bacteria that were transformed is not a true statement.

Explanation:

The bacterial culture is genetically engineered with recombinant plasmids containing genes resistant to penicillin, hence when treated with penicillin, the bacteria will not be killed.

Bacteria develops resistance to chemicals or drugs like antibiotics namely penicillin over the course and becomes resistant to the drug action. The effectiveness of the drug will either be reduced or eliminated and the bacteria gains the ability to survive, reproduce and grow and increase their colony.

Recombinant bacteria will undergo genetic mutation and can develop resistance against antibiotics like penicillin. The recombinant plasmids further provides extra protection and prevents the entry of drugs or chemicals into the bacterial cell.

The Celsius temperature scale is also something called the centigrade scale. Why is this?
valentinak56 [21]
There are three temperature scales in use today, Fahrenheit, Celsius and Kelvin.

Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two being divided into 180 parts. The 18th-century German physicist Daniel Gabriel Fahrenheit originally took as the zero of his scale the temperature of an equal ice-salt mixture and selected the values of 30 and 90 for the freezing point of water and normal body temperature, respectively; these later were revised to 32 and 96, but the final scale required an adjustment to 98.6 for the latter value.

Until the 1970s the Fahrenheit temperature scale was in general common use in English-speaking countries; the Celsius, or centigrade, scale was employed in most other countries and for scientific purposes worldwide. Since that time, however, most English-speaking countries have officially adopted the Celsius scale. The conversion formula for a temperature that is expressed on the Celsius (C) scale to its Fahrenheit (F) representation is: F = 9/5C + 32.

UNO [17]

Answer;

Neuromuscular

-Neuromuscular is the factor affecting the client's ability to perform self care.

Explanation;

-Multiple sclerosis (MS) is a potentially disabling disease of the brain and spinal cord (central nervous system). Muscular weakness are due to abnormalities in the central nervous system, which leads to the need to minimize the possibility of postoperative residual neuromuscular relaxation.

-Multiple sclerosis (an example of demyelinating disease) is characterized by inflammation and selective destruction of myelin in the central nervous system, while the peripheral nervous system remains immune.

The theory of adaptation is valid because scientist?
denpristay [2]
Theory of adaptation is valid because scientist can see facts that supported the theory. Adaptation makes organism survive especially in this rapid changing world. For instance, parts of human anatomy like appendix and tail bone were still present in humans but are no longer functional.
