Answer:
Your heart changes its rate depending on the activity, so that it can carry blood to your muscles, and therefore it needs to beat stronger if you are performing some exercise, or not so strong if you are sleeping, for example.
Explanation:
Your heart is continuously beating to keep blood circulating throughout your body.
So, here it is why your heart changes its rate: Its rate changes depending on your activity level; it is lower while you are asleep and at rest and higher while you exercise to supply your muscles with enough freshly oxygenated blood to keep the functioning at a high level.
And how: depending on your activity level, your heart has to pump enough blood to your muscles. Blood carries needed oxygen and other nutrients. Muscles need more blood sugar than any other tissue especially when working hard. To supply your muscles with oxygen your heart needs to beat faster, and this builds up your heart muscles.

Answer:
Based on the data in Table 1 and the biomass of the very large animals eaten by the lions, predict the likely effect on both the lions and leopards if the availability of the very large animals becomes limiting in the reserve. After analyzing the data, the scientists claim that the leopards and lions coexist in the reserve through the use of niche partitioning. Use evidence from the data provided to support the scientists’ claim.
