Answer:

Thick diameter, Myelinated

Explanation:

A alpha neurons conduct action potentials faster because of their large axon diameter and myelin.

  • The large diameter is less resistant to the flow of ions and allows for faster conductivity.
  • The myelin sheath is a layer of fat acting as to insulate the axon which helps increase signal conductance.

Answer: thick diameter, myelinated are needed for faster signal propagations.

Explanation:

These are the largest neuron in the spinal cord.  Based on structure their axons  are large , myelinated( surrounded with deposits of myelin sheath)and multipolar(many dendrites) .

These structures are  related to their functions, thus the big size is related to large diameter of the axon, while the multipolarity for integration of information from multiple neurons  need myelinated  axons for fast sultatory conduction during   receptions of  sensory inputs

Their major function is innervation of muscles fibre that are concerned with muscle contraction, where they form motor unit thus  reasons for above characteristics.

Therefore  Myelinated to allow fast salutatory conduction velocity  of  range of  80-120 m/s for action potential

and

large diameter of 13-20 micro meter which offers little resistance to flow of action potential are the correct answers

A muscle contraction usually begins when
shepuryov [24]

Answer:

For a contraction to occur there must first be a stimulation of the muscle in the form of an impulse (action potential) from a motor neuron (nerve that connects to muscle). Note that one motor neuron does not stimulate the entire muscle but only a number of muscle fibres within a muscle.

In the cranes what does songsam recall in the two flashbacks to his childhood? explain how these memories motivate songsam's act
True [87]
The "Cranes" is a short story book written by Hwang Sunwon. The story is set in Korea during the Korean War and focuses on two childhood friends, Songsam and Tokchae, who are on opposite sides during the war. Songsam has two flashbacks of his childhood memories with his friend Tokchae, where he remembers how they used to climb the trees and catch cranes. These flashbacks act as a reminder of the times he had spent with his friend and the importance of this friendship. As a result, these memories motivate him to let Tokchae free.

Which of these is classified as an emerging virus that can have a direct impact on human health?
umka21 [38]

Answer:

The correct answer is: D. Ebola.

Explanation:

  • Ebola Virus is a single-stranded RNA (ribonucleic acid) virus.
  • The natural host of the virus is Fruit bat but it can also infect humans.
  • The transmission of the virus into humans is mediated from infected bats through body fluids.
  • The major disease caused by the virus is is Hemorrhagic fever. In this disease, the platelet (responsible for clotting of blood) count in the blood  drops far below normal. As a result, bleeding can get initiated both in the body interior or exterior. This disease can cause multiple organ failure and death.
  • Recently, in the year 2018, the Central African country, Democratic Republic of Congo experienced a severely fatal endemic due to the Ebola virus that killed many people within a short period of time.
