How do mutation, genetic recombination during sexual reproduction, and lateral gene
Nikolay [14]
A mutation occurs when there are changes in the gene structure of organisms. It may either increase or decrease the fitness of organisms. However, for mutations to be evident in an organism, it must be inherited by the offspring.

On the other hand, genetic recombination occurs during the sexual reproduction of two parents. During this process, different gene combinations or genotypes are produced. This event is similar to shuffling a deck of cards.

Lateral gene transfer occurs when the genetic material is transferred between organisms. This is not the same as transferring the genes from parent to offspring. This process usually occurs in single-celled organisms such as bacteria and plasmids.

Primary producers generally form the smallest trophic level of a pyramid of energy true or false

Although we have discussed single-slit diffraction only for a slit, a similar result holds when light bends around a straight, t
QveST [7]
<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
