1.) Sexual reproduction increases genetic diversity in many species of plants and animals because of meiosis. During meiosis, crossing-over occurs and changes up genes in the chromosomes. Each gamete (sperm and egg), have half the chromosomes (23) and combine to have 46 chromosomes. This is how you get traits from your parents that make you different.

2.) Asexual reproduction occurs when a single parent copies its own DNA and genes and grows an identical version or clone of itself.

Monochromatic light of wavelength 491 nm illuminates two parallel narrow slits 6.93 μm apart. Calculate the angular deviation of

Papessa [141]

To solve this problem we will apply the concepts related to the double slit experiment. Here we test a relationship between the sine of the deviation angle and the distance between slit versus wavelength and the bright fringe order. Mathematically it can be described as,

$dsin\theta = m\lambda$

Here,

d = Distance between slits

m = Any integer which represent the order number or the number of repetition of the spectrum

$\lambda$ = Wavelength

$\theta$ = Angular deviation

Replacing with our values we have,

$(6.93*10^{-6}) sin\theta = (3)(491*10^{-9})$

$\theta = sin^{-1} (\frac{(3)(491*10^{-9}}{6.93*10^{-6}) })$

Part A)

$\theta = 0.2141rad$

PART B)

$\theta = 0.2141rad(\frac{360\°}{2\pi rad})$

$\theta = 12.27\°$
