Answer:
a.transmit sensory input to the CNS
Explanation:
Afferent neurons will take input from your muscles, skin etc. and send it to your CNS (usually via spinal nerves).
Answer:
wavelength: the distance between successive crests of a wave
frequency: the rate per second of a vibration constituting a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light)
electromagnetic energy is used for wifi, cell phones, microwave ovens etc.
the electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visisble light, ultraviolet, xrays and gamma rays
the only part we can see is visible light
visible light can be characterised by the colours of the rainbow
the longest wavelength is red and the shortest is violet
when combined, the colour is perceived as white or beige
Answer:
Possess striations. (Option A)
Explanation:
Skeletal muscle fibers are known as the type of striated muscle tissues and the somatic nervous system helps to control them. With the help of the bundle of collagen fibers which is called tendons, skeletal muscle cells attached to the bones.
Skeletal muscles are cylindrical and long in structure. While seeing under the microscope they have striated, and this striation occurs by the presence of actin, and myosin contractile proteins. Some functions of Skeletal muscle fibers are:
1) They help in contraction, and cellular physiology.
2) They help in signal transduction pathways.
