Answer:
28.2%.
Explanation:
Attack rate of any pathogen describes the speed or morbidity by which the new or emerging population is at risk by the attack of the pathogen.
The attack rate can be calculated by the formula:
Attack rate = people affected or at the risk of infection / Total population.
65 people are affected and 72 people also shows the symptoms.
Attack rate = 65 + 72 / 485
Attack rate = 137 / 485
Attack rate = 0.28.
The attack rate percent = 0.28 × 100 = 28%.
Hence, the answer is 28%.
For sensory information to be relayed the nerve cells should have an axon.
<u>Explanation</u>:
- Nerve cells or neurons play a critical role in transmitting signals from various sense organs of the body to the spinal cord where it is processed.
- Neurons have different parts - the dendrites which are tiny branches that receive incoming signals from the body, the nucleus, and the axon.
- The axon is a long fiber that is covered by a protective layer called myelin sheath. It is this structure of the nerve cell or neuron that helps transmit signals to the Central Nervous System of which the spinal cord is a part.
