Answer: The angle of refraction is 32°
Explanation:
By snell law, we have that:
n₁*sen(θ₁) = n₂*sen(θ₂)
Where n₁ = 1.5
n₂ = 2.0
θ₁ = 45°.
then we want to find the angle of refraction.
1.5*sin(45°) = 2*sin(x)
x = Asin(1.5*sin(45°)/2) = 32°
Answer:
Option A, by having a constant supply of blood
Explanation:
Blood that flows to the muscles bring oxygen from the atmosphere to the contracting muscles where it gets consumed. During large muscle exercise, two physiological needs arise – a) high and prolonged muscle blood flow and b) regulation of blood pressure so that there is adequate perfusion of pressure to all organs. In order to meet both the requirements, the blood flow increases so that the vasoligating muscles do not outstrip the cardiac output.
Hence, option A is correct
The first species that colonizes new of undistributed land is called as pioneer species, or simply pioneers. If you check the meaning of pioneer, it's a type of person or entity that became the first to explore or exploit a certain something. In this case, they were the first species who explores the lands to create a society.
