Explain how an organism's ability to survive and reproduce can affect the entire population
inn [45]

Answer:

The organism will pass on the traits to their offspring. If the offspring also has an increased chance of survival it will have a higher chance of passing on the traits. Over a long period of time the entire population can inherit this trait.

Explanation:

According to the theory of natural selection organisms with beneficial traits are more likely to survive to the reproductive stage and pass on the beneficial gene to their offspring. <em>Natural selection selects beneficial traits.</em>

What are the common stereotypes about the masculinity?
Zigmanuir [339]

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.

Muscle cell activity increases and ATP decreases below the set-point, a sensor molecule detects low ATP and activates protein ki
sergeinik [125]

Answer: Feedback mechanism

Explanation:

Feedback mechanism is the body's way of maintaining physiologic processes in the body. These physiologic processes include maintaining homeostasis, production of energy, hormones as well as enzymes required for chemical reactions.

There are 2 types of feedback mechanism:

  1. Positive feedback: The stimulus (message) sent to the brain, produces prolonged increased production or increased activity in the body.
  2. Negative feedback: In negative feedback, the stimulus causes production, secretion or activity till a set point where the body knows it has taken enough. This causes a self termination of the process.

In the increased muscle activity, the increase in activity in turn causes a decrease in energy (ATP) and serves as the stimulus leading to the release of enzymes which in turn lead to increased absorption of glucose which will be used by the body to produce more ATP needed for the muscular activity. At the end of the muscular activity, the body recognizes that it doesn't need an increased absorption of glucose to support increased activity anymore and glucose absorption normalizes.
