Answer:
C) 86 J of energy for every 100 J that enter it.
Explanation:
Efficiency is a measure of performance of an engine which can be calculated by the formula as given below to get in percentage:
Efficiency = energy output/energy input x 100
If the efficiency of a car’s engine is 14 percent it means that for every 100 joules of energy that is entered into it, only 14 joule is converted into useful output and rest of the 86 Joules is wasted.
The efficiency of any machine is never 100%, however, if any machine miraculously converts all the input energy to useful output energy, it means it is 100% efficient.
Hope it helps!
Answer: Genetic engineering is a tool in biotechnology wgich is beneficial to both the organism, the society and the environment.
What is genetic engineering?
Genetic engineering is a technique in biotechnology in which genes of organisms are manipulated to produce desirable effects in the organism.
Genetic engineering provided benefit to both the organism as well as the society.
To the organism, it gives the organism an advantage of increased chances for survival, for example producing disease-resistant crops.
To the society, it enhances food production as plants produce more food when healthy.
To the environment, it enables these disease to disappear as they can no longer affect organisms.

Answer:
Penicillin binds and inhibits bacterial enzyme DD-transpeptidase.
Explanation:
Penicillin is made up of 4 rings of β-lactam and acts by binding to DD-transpeptidase of bacteria. The DD-transpeptidase facilitates the cross-linking of the peptidoglycan cell wall of bacteria. This leads to malformation of the protective cell wall of the bacteria and causes it to lyze and die.
