Kulper belt

6.5 billion km = 6.5e9 Km

1 Km = 6.68459e-9 Au

6.5e9 Km = x

Solving for x;

x = 43.45 Au

Alpha Centauri

44 trillion km = 4.4e13

1 Km = 6.68459e-9 Au

4.4e13 km = x

Solving for x;

x = 294121.83 Au

Why is cellulose so difficult for most animals to digest?
NNADVOKAT [17]
The answer is C .Cellulose is a long chain of glucose and to be able to use any of the energy stored in them an organism must break it down into single glucose molecules, and this is why most animals go for a different diet. The chain is very difficult to break down and must be treated with concentrated acids at high temperature. This is a hard task to do and often time needs many stomachs.
