Answer:im not sure
Explanation:Errors in protein synthesis disrupt cellular fitness, cause disease phenotypes, and shape gene and genome evolution. ... At this error rate, 15% of average-length protein molecules will contain at least one misincorporated amino acid. Polypeptide errors can induce protein misfolding, aggregation, and cell death (e.g. Ref.
Answer:
Positive and negative feedback differs in that positive feedback loops increase the initial signal, while negative feedback loops decrease the original signal (option d).
Explanation:
Feedback is a process that, applied to biological systems, allows for the changes needed to maintain homeostasis.
- Negative feedback loop occurs when a stimulus is presented, producing a change in the body, so the response is to stop the change that is occurring. It is the most frequent type of feedback and has the greatest impact on homeostasis. An example of negative feedback is a decrease in body temperature through sweating.
- Positive feedback loop occurs when the stimulus produces a change and promotes a response that reinforces that change. The classic example of positive feedback is the secretion of oxytocin, promoted by uterine contractions, whose effect is to increase those contractions, allowing labor.
<em>In summary, </em><u><em>positive feedback loop acts by increasing an action or signal in the body, while the negative feedback loop reduces or stops the action or signal that occurs</em></u><em>.</em>
There are positive and negative charges. Look at is this way a charge attracts a positive charge. On the other hand, when a charge is brought near a distributed charge, high is your hair for this, the positive charge attracts the negative charge so opposite charge concentration increases in the hair. So, when the same type of charge is in the hair, the hair stands up.
