Answer:
It causes light to slow down significantly
Explanation:
The index of refraction of a substance describes the speed of light in that substance, as a ratio of the speed of light in vacuum to its speed in that substance.
just search it up and there is your answer
Answer:
the pig's average speed is 7 m/s
The enzymes and their respective substrates are as follows:
- Protease enzymes such as trypsin and chymotrypsin break down proteins
- Carbohydrate enzymes such amylase and maltase break down carbohydrates
- Lipase enzyme breaks down lipids.
In the small intestine, a protease enzyme known as chymotrypsin breaks down protein, pancreatic amylase breaks down carbohydrates, while pancreatic lipase breaks down lipids.

The grams of oxygen that are required to produce 1 mole of H₂O is 16 g ( answer B)
<u><em> calculation</em></u>
2 CH₄ + 2NH₃ +3 O₂ → 2HCN + 6H₂O
step 1: use the mole ratio to find moles of O₂
from equation above the mole ratio of O₂: H₂O is 3:6 therefore the moles of O₂ = 1 mole x3/6 =0.5 moles
step 2: find mass of O₂
mass= moles x molar mass
from periodic table the molar mass of O₂ = 16 x2= 32 g/mol
mass O₂ = 0.5 moles x 32 g/mol = 16 g (answer B)
