Antibiotics are routinely introduced into the food of cattle, chickens and other livestock, which causes the animals to grow fas
Rudik [331]

Answer:

Bacteria are highly adaptable microorganisms who have the capability of developing defense mechanisms against that which may harm them. Not least important of all, is the easiness with which some bacteria, especially pathogenic bacteria like Salmonella, or Klebsiella, develop mechanisms of resistance to antiseptics and, most importantly, antibiotics.

Antibiotics are a chemical substance that was created, and has been developed, in order to be able to combat pathogenic microorganisms, specifically bacteria. However, because today these substances are being used indiscriminately, we are now seeing a very worrying pattern of antibiotic-resistance patterns in microorganisms that used to be sensible to them. The result, we are facing strains of pathogenic bacteria, like Klebsiella pneumonia and E. Coli, that have become resistan to all types of antibiotics, from first generation, to fourth generation. And this has meant that when people acquire infection by these pathogens, the likelihood of death by them has increased because there are no agents capable of combating them.

Exposure to antibiotics has been the sole reason why these resistant strains of bacteria have emerged, especially when these antibiotics are not necessary. And feeding these substances to animals, to ensure their development and weight gain, has not made the situation any better. Now, we are instead adding also bacteria to the list that did not use to be resistant, but that are becoming so as they become adjusted to the constant exposure to antibiotics. Again, the result has been: more people infected with bacterial strains that cannot be combated with any of the existing antibiotic agents.

Viktor [21]

Answer:

The correct answer to the question: The pineal body secretes which hormone that maintains the body´s internal clock, the 24-hour wake-sleep cycle, and regulates the onset and duration of sleep?, would be, C: Melatonin.

Explanation:

The process of sleep and wakefulness, also called the circadian cycle, its a pretty complex system that is controlled by several parts of the brain, but most importantly, structures of the diencephalon (vital is the hypothalamus), the pineal gland, and the stem of the brain. All these structures, and some others, respond to changes both in light perception by the eyes and other senses, heat, and homeostatic balances. These factor play a vital role in telling the human body that it is time for sleep, or to awaken. The pineal gland, as part of this melody, is essential, as it secretes the hormone, melatonin, in response to light changes. Melatonin will balance out the process of sleep, when it is secreted in high quantities by the pineal gland, and wakefulness, when it is no longer secreted in response to the presence of light. This is what is called the circadian cycle.
