Answer:
Heart disease is a non communicable disease because it does not happen due to any virus or bacteria.
Explanation:
Diseases caused due to virus and bacteria are mostly communicable. Heart Disease is caused due to poor supply of nutrients in hearts.
Why temperature affects heart rate in ectothermic organisms? If the temperature is within the optimal range for enzyme activity more ATP will be produced and the heart will beat faster due to increased metabolic activity and energy availability.
The carbon footprint can be decreased by a great amount if the incandescent bulbs are replaced with the compact fluorescent bulbs. The compact fluorescent bulbs uses approximately seventy five percent less energy than the incandescent bulbs as they do not use heating mechanism to light. This leads to less emission of the green house gases and thereby reducing the carbon footprint.
Hence, the correct answer is 'option a - replacing incandescent bulbs with compact fluorescent bulbs'.
Well its most likely over hunted but if its endangered and not allowed to be hunted then it would be because of natural predators in the area being over populated and taking out the caribou to fast
