Answer:
They are food for some animals. Some animals use them for nesting material. Humans can dry and burn some types of nonvascular plants as a fuel.
Explanation:
Some nonvascular plants produce various nutrients that are passed to the soil and can be used by other plants. Also, nonvascular plants that cover a large surface area help maintain the cohesion of the land by reducing the risk of erosion. Nonvascular plants are also very important to animals.
Answer:
option C is correct
Explanation:
oxidation number is the apparent charge on an atom which it acquire after lose or gain of electron
From the information provided in the question, we can see that; the electron moved up to an energy level and has an energy of 21.72 x 10-19 J.
Bohr's model of the atom tells us that electrons are found in certain specific energy levels. Energy is absorbed when an electron moves from a lower to a higher energy level and energy is released when an electron moves from a higher to a lower energy level.
Given that;
ΔE = E2 - E1
E2 = final energy level
E1 = initial energy level
E2 = ?
E1 = 16.32 x 10-19 J
ΔE = 5.4 x 10-19
E2 = ΔE + E1
E2 = 5.4 x 10-19 + 16.32 x 10-19 J
E2 = 21.72 x 10-19 J
