Answer:
100,000 TMV
Explanation:
Length of one TMV is 300nm. Length of paper clip is 3.0cm. First step is to convert either value to match the units of other.
So 3.0cm to nm is 3.0 * 10^7 = 30,000,000nm
SO now it becomes simple because we just divide the total length by length of TMV to find number of particles that can fit:
30,000,000/300 = 100,000 TMV
Answer:
All types of feedback loops help to maintain stability in a system.
Explanation:
The feeedback system is a physiological system composed of negative and positive feedback. Both have the primary function of maintaining the homeostasis of our organism, that is, maintaining a balance in all factors of our body in relation to the internal and external environment.
It is through negative and positive feedback that our organism is able to keep hormone secretion regulated, controlling body temperature, blood flow and blood pressure, consequently, in addition to promoting harmony between all the systems, organs and tissues of our body.
