Neuroglia do all of the following except:______. a. transmit electrical impulses. b. regulate interstitial fluid composition. c.
Ivenika [448]

Answer:

Option A, transmit electrical impulses

Explanation:

Neuroglia also known as glial cells which act as supporting cells for the nervous system and its functioning. These cells surrounds the neurons and produce insulation between them as they produce myelin sheath that coats the axon. There are six types of neuroglia cells and they all work to provide essential nutrients to the neuron cell and also maintain the homeostasis (under which it also regulate the interstitial fluid composition and repair tissue framework)

John and Joshua used a light microscope to observe a plant cell. They indicated the magnification as x1000. Given the eye piece
Zinaida [17]

Answer:

Objective Lens Magnification = ×100

Explanation:

In a microscope, the ocular (eyepiece) lenses are usually to a magnification of ×10, meaning that it magnifies the image 10 times. While the standard objective lenses have magnifications of ×4, ×10, ×40, and ×100.

In order to work out the total magnification, the individual magnifications of the ocular and objective lenses have to be known, after which a simple multiplication of both magnifications will give the total magnification used.

Total Magnification = (eyepiece lens magnification) × (objective lens magnification)

1000 = 10 × obejcetive lens magnification

Dividing both sides by 10

Objective lens magnification = 1000 ÷ 10 = 10

∴ Objective lens magnification = ×100
