Explanation: No animal has the ability to digest cellulose directly.
Most animals such as horses and termites cannot directly digest cellulose. The animals have a symbiotic relationship with bacteria in the intestinal tract. The symbiotic bacteria acts on the cellulose and secrets the necessary enzymes (cellulase) to digest cellulose in the intestinal tract. An example of such microorganism in a symbiotic relationship with animals that facilitates the digestion of cellulose is Trichonympha
Answer:
The arc is 6.4 units long.
Explanation:
For a circle of radius R, the circumference is given by:
C = 2*pi*R
If we have a section of this circle defined by an angle θ (such that this section makes an arc), the length of that arc is:
A = (θ/360°)*2*pi*R
and 2*pi*R is the circumference, then we can write the length of the arc as:
A = (θ/360°)*C
qsIn this case, we know that the circumference is equal to 8 units, and the arc has an angle of 288°
Then the length of that arc is:
A = (288°/360°)*C = (288°/360°)*8 = 6.4
The arc is 6.4 units long.
