Why does the brain not feel pain?

Biology
1 answer:
blondinia [14]3 years ago
6 0

Answer:

The brain itself does not feel pain because there are no nociceptors located in brain tissue itself. This feature explains why neurosurgeons can operate on brain tissue without causing a patient discomfort, and, in some cases, can even perform surgery while the patient is awake.

Some bacteria are propelled by biological motors that spin hair-like flagella. A typical bacterial motor turning at a constant a
koban [17]

Answer:

Angular speed of the bacteria motor is 1447rad/s

t = 4.342 × 10^-3 seconds

Explanation:

Hint: Do you remember circular motion in physics???

Okay, let's go

Given:

radius of 1.61 10-8 m

tangential speed at the rim of 2.33 10-5 m/s

Let's recall that angular velocity

ω = Vt/r

Where,

Vt = 2.33 10-5 m/s

r = 1.61 10-8 m

ω = ?

ω = 2.33 ×10-5 m/s = 1447rad/s

1.61 ×10-8 m

Angular speed of the bacteria motor is 1447rad/s

Let's find the elapsed time too

Since The angular velocity is said to be constant, there will be no acceleration (a = 0)

Using:

θ = ωot + (1/2at^2)

t = θ/ωo

(θ = 1 revolution or 2π rad, ωo = 1447rad/s)

t = (2π rad)/(1447 rad/s)

t = 4.342 × 10^-3 seconds

Which correctly lists the three gases that are part of Earth’s cycles in both the atmosphere and biosphere? radon, carbon monoxi
serg [7]

The three gases that are part of Earth’s cycles in both the atmosphere and biosphere are:

  • oxygen
  • - nitrogen
  • - carbon dioxide

<h3>Explain your answer?</h3>

The oxygen,  nitrogen, and carbon dioxide are the three gasses that are constantly moving through the atmosphere and biosphere in their own respective cycles.

The oxygen is used by the animals for breathing, but it is also released as a byproduct by the producers. The nitrogen is used as a food source for the producers, as well as the carbon dioxide which is crucial for the process of photosynthesis.

Thus, Part of them is released through decomposition, part by releasing them in the atmosphere or in the soil.

Dmitriy789 [7]

Answer:

Yes. That was the question he was trying to answer.

Explanation:

To conduct the experiment investigating the connection between pillows and disease-causing gems, Dr. Philip needs to ask himself whether the pillows that will be used in the research contain germs that contribute to allergies in a family. This question allows Dr. Philip to have the basis to start his research and come to a conclusion about the pillows used in the research. Furthermore, the research points directly to the main point of the story.

Which is a benefit to using transplants instead of seeds to start your Phoenix vegetable garden?
bija089 [108]

Answer:

The planting method using transplants allows the selection of vigorous and healthy seedlings, which enables the production of uniform bulbs which can mean harvesting garden edibles sooner.

The expenditure on seeds is lower, the consumption of irrigation water during the period of seedling formation is reduced and the management of fertilization, weeds and diseases and pests is facilitated in comparison with direct sowing. On the other hand, this method requires a lot of labor.
