What is a virus envelope in biology?

1 answer:

3 0

The Virus Envelope is where the capsid is surrounded by lipid bilayer that contains viral proteins, usually including the proteins that would enable the virus to bind to the host cells. and is derived from the host cell membranes. They may help viruses avoid the host immune system. The viral envelope then fuses with the host's membrane, allowing the capsid and viral genome to enter and infect the host.

<h2>Width of hair is "1.96 10⁻⁵ m"</h2>

Explanation:

For this diffraction problem they tell us that it is equivalent to the diffraction of a single slit, which is explained by the equation
a sin θ =± m λ
Where the different temrs are: “a” the width of the hair, λ the wavelength, θ the angle from the center, m the order of diffraction, which is the number of bright rings (constructive diffraction)
We can see that the diffraction angle is missing, but we can find it by trigonometry, where L is the distance of the strand of hair to the observation screen and "y" is the perpendicular distance to the first minimum of intensity
L = 1.25 m 100 cm/1m = 125 cm
y = 5.06 cm
Tan θ = y/L
Tan θ = 5.06/12
θ = tan⁻¹ ( 0.0405)
θ = 2.32º
With this data we can continue analyzing the problem, they indicate that they measure the distance to the first dark strip, thus m = 1
a = m λ / sin θ
a = 1 633 10⁻⁹ 1.25/sin 2.3
a = 1.96 10⁻⁵ m
a = 0.0196 mm
Hence, "the width of the strand of hair is 1.96 10⁻⁵ m" is correct answer
