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°

If a wide-spectrum fungicide that kills all fungal species were used extensively in a forest, what effects would you expect the
Ne4ueva [31]

Answer:

It would harm the few plants that benefit from mutualistic relationships with mycorrhizal fungi

Explanation:

Mycorrhizal relationship is a symbiotic relationship between fungi and the roots of higher plants. While the plant provides the fungi with food, the fungi supply the plant with nutrients and water extracted from the soil.

<em>Hence, if a wide-spectrum fungicide is used in a forest and it kills all the fungi in the forest, it will affect all the plants that share beneficial relationship with fungi in the forest.</em>
