Hi!
The correct option would be A) Mendel’s genetics states laws that are now part of the theory of biological evolution.
When Darwin proposed the idea of biological evolution, which revolved around the concept that favorable genes are naturally selected into a species to ensure survival, his theory was criticized as during that time there was the idea that individual traits of two parents would present themselves as a blend in the offspring.
Gregor Mendel's theory of inheritance supported Darwin's idea as it dealt with the transmission of traits in generations through entities called genes, which were present in pairs for a particular trait.
Hope this helps!
That's called an "acceleration" or "slowing down".
Answer:
A sound wave can be affected by a lot of different variables. As an audio engineer some of the more common things we deal with involve air temperature, humidity and even wind. The first two affect the speed at which the wave travels, while wind can actually cause a phase like effect if it is blowing hard enough. Another big one though not directly related to the air is walls and other solid objects that cause the sound wave to bounce off of them and reflect. This causes a secondary wave that isn’t as strong as the first wave but is the cause of “muddy” sounding venues when you are indoors.
Explanation:
Answer:
PART A: option b. .43nm
PART B: option d. 0.11nm
PART C: option c. The wavelengths of visible light are too long compared to the atomic spacing.
Explanation:
Given data
Wavelength λ = 0.20 nm
Angle θ = 0.8 rad
(a)
wavelength of x-ray to give maximum at the same location
λ₂ = m λ
Here, m = 2 is the interference fringe order.
Substitute the values in the above equation.
λ₂ = 2 × 0.2
= 0.4 nm
Hence, the wavelength of x-ray to give maximum at the same location is 0.4nm
(b)
The crystal plane separation is equal to d
The value of θ is equal to 0.8 rad.
Convert rad into degree as follows:
0.8 rad = 
= 144°/π = 45.86°
Solve for d, using equation (1) as follows:
2dsinθ = mλ
d = mλ / 2sinθ
d = (1) 0.17 / 2Sin45.86°
d = 0.17 / 1.9065
d = 0.089 nm
(c)
The visible light can not be used to study the structure of proteins because of the high wavelength of the visible light.
