Which of these conditions indicate positive feedback has occurred?
aleksklad [387]

Answer;

A) Blood pressure decreases greatly; blood flow to the heart is inadequate, and blood pressure decreases.

Explanation;

-With negative feedback, the output reduces the original effect of the stimulus. While in a positive feedback system, the output enhances the original stimulus.

-Negative feedback is the most commonly used feedback loop in the body. Negative feedback is used to negate or counteract a stimulus without completely eradicating it.

-One key difference between the two feedback is that positive feedback loops are used to eradicate a stimulus. Another key difference is that responses through positive feedback become more amplified over time. So once a stimulus activates a positive feedback loop it is not turned off until the stimulus is completely removed.

Anna11 [10]
<span>Since alkylating agents work to prevent the cell from replicating its genetic material, the cell would most likely stop at the interphase checkpoint, which is the phase before mitosis (which consists of prophase, metaphase, anaphase, and telophase). During interphase, the cell replicates its genetic material (DNA), but this would be prohibited by alkylating agents.</span>

A researcher claims that genetic variation provides organisms with the ability to survive and reproduce in different environment
Igoryamba

Answer:

The researcher's claim is in the same way of the observation made because from it it is inferred that in a population of bacteria with genetic variation, in which some of them have plasmids and others do not, the population survives because those bacteria with plasmids are resistant to antibiotics, if for example there were only bacteria without plasmids all bacteria would die when using antibiotics so this is an example that genetic diversity is an evolutionary advantage
