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°
Phospholipids (lipid bilayer)
When the body becomes dehydrated, a chemical signal is sent that causes nephrons in the kidneys to absorb more water and excrete more salts. This is an example of a <em>D Feedback loop</em>.
Answer:
the behavioral adaptation of sleeping is called Hibenation
Explanation:
Hibernation is an adaptation that helps many animals conserve energy by remaining inactive, greatly slowing their metabolism and reducing their body temperature for days, weeks or even months at a time. specifically, animals hibernate in order to survive/live for long periods when food is scarce.
Endocytosis enables extensive particles to enter the cell, and exocytosis ousts vast atoms from the cell. Along these lines, the cell can acquire things it needs and disposes of things it doesn't. Exocytosis is the turn around process, where a cell ousts substantial particles, generally squander from cell forms.
