Answer:
1100
Explanation:
There is 10% of total energy in each increasing trophic level. 10,000 / 10 = 1,000 ,so there are 1,000 units of energy in trophic level 2.
1,000 / 10 = 100, so there are 100 units of energy in trophic level 3.
1,000 + 100 units of combined energy would be 1,100 units of energy.
Hope this helps!
Answer:
B. Shortens
Explanation:
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers

Explanation:
The pulse of the bodies raises for the first 20 seconds after sitting for a prolonged period of time and then to a standing position. It should, however, return to normal afterwards. The heartbeat of the body decreases because as you travel the blood needs to flow to the active areas and the blood flows downward from gravity, however you still need to pump blood to your brain. The rise in blood demand makes the heart pump more rapidly.
