Answer: C) GMOs, genetically modified foods engineered in a lab to produce desirable traits.

Explanation:

The genetic engineering involves the insertion of genes from other organism to the host organism so as to make up genetically modified organism. Some unwanted and default genes are also removed from the organisms so that their body function properly.

The genetically modified foods are the examples of genetic engineering. This is done to produce desirable traits in the food crops. In plants both plants and animal genes are inserted to improve the yield of crops, and to improve their quality. In animals, the insertion of genes of other animals is likely to improve the milk and meat yield.

Answer:

In the exercise-depression study by Blumenthal et al. (the SMILE study), which of the treatments had the best success when considering the percentage of individuals who had either recovered or at least partially recovered at a 6-month follow-up period? B. Exercise group.

Explanation:

Exercise has different depression-reducing effects. It enables the body to producte endorphins that reduce sensations of pain. Moreover, it changes the  neurotransmitter levels associated with depression (for example, norepinephrine) and it developes a sense of mastery and self-control through regular practice. <em>The SMILE study concludes that aerobic exercise on MDD remission extend the benefits</em> and it might be better than the benefits of antidepressant use.

Which of the following are examples of positive feedback loops? (Choose all that apply)
aleksley [76]

The examples of positive feedback loops are as follows:

  1. contractions during the process of giving birth
  2. Blood clotting

<h3>WHAT IS POSITIVE FEEDBACK LOOP:</h3>
  • Positive feedback loop is that in which a change in a given direction causes additional change in that same direction.

  • The contractions during the process of giving birth is an example of positive feedback loop because the contractions further stretch the walls and continues until birthing occurs.

  • Also, the clotting of blood causes the stoppage of blood flow.

Therefore, the examples of positive feedback loops are as follows:

  1. contractions during the process of giving birth
  2. Blood clotting

There, the nutrients are burned in the presence of oxygen (catabolism) to release energy.
