Answer: The Joker is a very popular character with boys, perhaps because laughter is part of their own “mask of masculinity.” A potential negative consequence of this stereotype is the assumption that boys and men should not be serious or emotional. However, researchers have also argued that humorous roles can be used to expand definitions of masculinity.
The Jock is always willing to “compromise his own long-term health; he must fight other men when necessary; he must avoid being soft; and he must be aggressive.” By demonstrating his power and strength, the jock wins the approval of other men and the adoration of women.
The Strong Silent Type focuses on “being in charge, acting decisively, containing emotion, and succeeding with women.” This stereotype reinforces the assumption that men and boys should always be in control, and that talking about one’s feelings is a sign of weakness.
The Big Shot is defined by his professional status. He is the “epitome of success, embodying the characteristics and acquiring the possessions that society deems valuable.” This stereotype suggests that a real man must be economically powerful and socially successful.
The Action Hero is “strong, but not necessarily silent. He is often angry. Above all, he is aggressive in the extreme and, increasingly over the past several decades, he engages in violent behavior.”
The Buffoon commonly appears as a bungling father figure in TV ads and sitcoms. Usually well-intentioned and light-hearted, these characters range from slightly inept to completely hopeless when it comes to parenting their children or dealing with domestic (or workplace) issues.

Answer: <u>Genetic Modification of crop plants.</u>
Explanation:
Genetic modification alters the genome of an organisms through the use of biotechnological tools and advancements in molecular biology. Usually, DNA is swapped among organisms, and between species; this is called transgenes. These altered plants are usually called transgenic organisms.
Some plants can be modified in several ways to meet global food security needs. These include:
-drought tolerance-plants grow in arid conditions with minimal water
-increased yield- plants produce more crop per input
Answer:
Denaturation, Annealing and Extension are the steps of PCR.
Explanation:
There are three steps of PCR process.
1) Denaturation
2) Annealing
3) Extension
In the first step, the DNA denatures when they are allow to heat. In Annealing, the process of polymerization occurs. Polymerase chain reaction (PCR) is a method which is used to formed or produce billions of copies of a particular DNA sample. In this process, monomers attached to one another to form polymers and the process is known as polymerization. In the extension, new strands of DNA are formed by using the old DNA strands as a template.
