Nerve cells transmit electrical signals through their long tubular axons. These signals propagate due to a sudden rush of Na+ io

ns, each with charge +e, into the axon. Measurements have revealed that typically about 6.2×1011 Na+ ions enter each meter of the axon during a time of 13 ms.

3. Which types of light are not absorbed by genetic material?
Radda [10]

Given what we know, we can confirm that genetic material is not known to absorb light originating from an infrared or microwave radio source.

<h3>What light does genetic material absorb?</h3>
  • Genetic material is known to absorb UV light.
  • This represents ultraviolet light.
  • UV light is electromagnetic radiation, and the primary source of UV light that we are exposed to is the sun.

Therefore, given that the only form of light listed that genetic material is known to absorb is that of Ultraviolet or UV light, we can confirm that the answer to the question proposed is infrared and microwave radio light.

A proton is released from rest inside a region of constant, uniform electric field E1 pointing due North. 32.3 seconds after it
NARA [144]

Answer:

E₂ / E₁ = 521.64 / 5.95 =87.67

Explanation:

Let d be the distance covered inside electric field . Lt q be the magnitude of charge.

Force under field E₁ = q E₁

acceleration = qE₁/ m

d = 1/2 a t²

d = .5 ( qE₁ / m) x 32.3²

d = 521.64 ( qE₁ / m)

Similarly for return journey,

d = .5 x ( qE₂ / m) x 3.45²

d = 5.95x( qE₂ / m)

521.64 ( qE₁ / m) = 5.95x( qE₂ / m)

E₂ / E₁ = 521.64 / 5.95 =87.67
