Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. In vertebrates, it is composed of blood cells suspended in blood plasma.

Lactase and carbonic anhydrase are examples of what type of substance?

svetlana [45]

<span>The answer is enzymes. Enzymes are biological catalysts and increase the speed of change from substrate to product. The name of enzymes is usually derived from the substrate they break down. For example, lactase breaks down sugar lactose. The name of enzymes contains suffix -ase, for instance, carbonic anhydrase, lactase, lipase, amylase, etc...</span>

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
