Answer: Disagree
Explanation:
I tend to disagree with this statement because predators actually have a place in ecosystems to keep prey species from becoming overpopulated, hence, the extent of the overpopulation would likely have been much less if the natural predators were allowed to play a role in controlling the deer population.
Answer:
It's always associated with motion
It can be transferred from one object or body to another
Explanation:
Kinetic energy is the energy due to motion of a body.
- Moving objects possess kinetic energy which is resident in that body.
- As with other forms of energy, it can be transferred from one body to another.
- Kinetic energy can express itself as thermal energy, electrical energy, mechanical energy etc..
- As a body moves, the kinetic energy is increases.
Answer:
Cross-bridges would form in the absence of an action potential from a motor neuron.
Explanation:
The injected calcium ions would bind to troponin. Troponin would make tropomyosin move away from the myosin-binding sites on actin. The presence of free binding sites on the actin would be followed by the contraction cycle. This would include hydrolysis of ATP to energize myosin heads and binding of these heads to actin to form cross-bridges. Therefore, cross-bridge formation would occur without any action potential if calcium ions are injected directly into the muscle.
