If a sloth is traveling at its top speed of 0.067 m/s (0.15 mph), how long does it take the sloth to travel a 11.5 meter tree?


2.86 minutes


5.42 minutes


17 minutes


Answers

It would take the Sloth 2.86 minutes to  travel a 11.5 meter tree when moving at 0.067 m/s.

Speed is the ratio of distance travelled to the total time taken. It is given by:

Speed = distance / time

Given that the sloth moves at 0.067 m/s and travel a 11.5 m tree, hence:

Speed = distance / time

0.067 = 11.5/time

time = 171.64 seconds

Time = 2.86 minutes

Hence it would take the Sloth 2.86 minutes to  travel a 11.5 meter tree when moving at 0.067 m/s.

what can you infer about carbon dioxide from the fact that your body needs to breathe it out?

Answers

Answer:

You can infer that carbon dioxide is the chemical you breathe out

Explanation:

From prior knowledge we know that we breathe in Oxygen, so with this information given we can infer that.

[Hope this helped!]

Carbon dioxide is released by the body that needs to breathe it out, so it can be harmful if it builds up in the bloodstream.

What is carbon dioxide?

Respiration is the process through which an organism takes in gases and exhales them into the environment. Due to food digestion and oxygen inhalation, the organism's body exhales carbon dioxide back into the environment.

Food molecules are broken down into energy, water, and carbon dioxide during cellular respiration. In the presence of oxygen, cells respire, which involves a number of chemical processes.

Krebs cycle, phosphorylation cycle, and citric acid cycle are daily cycles. Glucose breaks down into carbon dioxide, water, and ATP when coupled with oxygen.

Therefore, because carbon dioxide must be exhaled by the body, its accumulation in the bloodstream can be dangerous.
