<span>The fourth level of cell organization is the
organ level. The organ level is a structure composed of collections of tissues
that perform specific functions in a living organism. Organs that are found in
a human body are the heart, lungs, brain, pancreas, liver, among others. These
organs perform specific functions and work in an interconnected manner for the
human body to function well. When organs work together, they are called organ
systems which are already the fifth level of cell organization.</span>
Most plants have roots, but there are some
exceptions. The exceptions are bryophytes
and the groups of green algae that are
classified as plants. Bryophytes have rootlike
structures called rhizoids for absorbing
water, but because rhizoids lack vascular
tissue they are not considered roots.
1. Several places in your digestive system secrete enzymes
2. Enzymes play an important role in every function in the human body
3. Enzymes help with nutrient absorption
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°
