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.

andrezito [222]

Answer:

the percent error expected from each of theses person's body:

in homes:

% E = 0.14267 %

in doctor's office:

% E = 0.257 %

Explanation:

  • ° C = ( ° F - 32 ) * (5/9)
  • % E = ( | true - exp | / true ) * 100
  • body temp = 38.9 ° C = 102.02 ° F

thermometer used in homes:

⇒ T = 102.02 ° F  +/- 0.1 ° F = 102.12 ° F ∧  101,92 ° F

⇒ T = 102.12 ° F  = 38.9555 ° C

⇒ % E = ( | 38.9 - 38.9555 | ) / 38.9 ) * 100 = 0.14267 %

in the doctor's oficce:

⇒ T = 38.9 ° C  +/- 0.1 ° C = 39 ° C ∧ 38.8 ° C

⇒ % E = (( | 39 - 38.9 | ) / 38.9 ) * 100 = 0.257 %
