Answer:

The neuron is the basic working unit of the brain, a specialized cell designed to transmit information to other nerve cells, muscle, or gland cells. Neurons are cells within the nervous system that transmit information to other nerve cells, muscle, or gland cells. Most neurons have a cell body, an axon, and dendrites.

Answer:

Neurons are information messengers. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system. ... Neurons have three basic parts: a cell body and two extensions called an axon (5) and a dendrite (3)

When the body requires an increased blood flow rate in a particular organ or muscle, it can accomplish this by increasing the di

horsena [70]

Answer: The percentage increase in diameter is 19%

Explanation:

<em>Using Poiseuille's law which states that Flow rate , Q = ΔPπr⁴/8ηl</em>

<em>where ΔP is pressure difference, π is a constant, r is the radius which is half of the diameter, η is viscosity of blood, l is length of blood vessel</em>

Let Q₁ be the intitial flow rate, Q₂ the final flow rate,r₁ and r₂ the initial and final radius.

Note: r = d/2, therefore, r₁⁴ = d₁⁴/16 r₂⁴ = d₂⁴/16

Also, Q₂ = 2Q₁, since the flow rate is doubled

Since all factors except diameter is constant, d₂⁴/16 = 2d₁⁴/16

d₂⁴/16 = d₁⁴/8

multiply both sides of the equation by 16

d₂⁴ = 2d₁⁴

taking the fourth root of both sides

d₂ = 1.19*d₁

d₂ - d₁ = 1.19d₁ - d₁

d₂ - d₁ = d₁(1.19 - 1)

d₂ - d₁ = 0.19d₁

d₂ - d₁/d₁ = (0.19d₁/d₁)*100%

(d₂ - d₁/d₁)*100% = 19%

Therefore, the percentage increase in diameter is 19%

Pavel [41]

Answer:

-15Nm

Explanation:

Work is said to be done when a force causes an object to change its position.

Workdone = Force × Distance

Given the force (−2i+2j+3k)N

Since the body moves from point (−5,4,3) to the point (−2,13,−6), we will take the difference of both points to get the distance covered.

The difference will be final point (-2,13,-6) minus initial point (-5,4,3) i.e (-2,13,-6) - (-5,4,3) = (3,9,-9)

This point can be represented vectorially as (3i+9j-9k)meters

Work done = (−2i+2j+3k)×(3i+9j-9k)

Note that i.i = j.j = k.k = 1, the multiplication of different components will give "zero"

Work done = (-2×3)+(2×9)+(3×-9)

Work done = -6+18-27

Work done= -15Nm
