Answer: Dermatomes are similar; however, a dermatome only specifies the area served by a spinal nerve. In some cases, the dermatome is less specific (when a spinal nerve is the source for more than one cutaneous nerve), and in other cases it is more specific (when a cutaneous nerve is derived from multiple spinal nerves.)
Explanation:
To allow resources to be replenished naturally is the most important reason to reduce demand for renewable resources.
- The term "renewable resources" refers to natural resources that are replenished by nature.
- These are resources that can be used indefinitely and are replenished naturally, such as sunlight, water, and air, among others.
- Natural resource exploitation and consumption harm the ecosystem and cause pollution.
- Utilizing less natural resources, such as wood and fossil fuels, will safeguard both environmental and human health.
- A natural resource that can be replenished to replace the portion used up by usage and consumption is known as a renewable resource, also known as a flow resource.
- This replenishment can occur naturally through reproduction or through other recurring processes in a limited amount of time on a human time scale.

Answer:
The correct order is: 6) Sarcoplasmic reticulum releases calcium ions, 2) Calcium ions bind to troponin, 5) Tropomyosin moves to expose active sites of actin, 4) ATP is split into ADP and P, 1) Myosin head binds to actin, 7) ADP and P released from myosin, 3) Myosin cross-bridges bend, pulling actin toward center of sarcomere.
Explanation:
The ability to contract is an important property of the muscle cells and is fundamental to animals because muscles not only make locomotion possible but are also responsible for the correct functioning of organs (including the heart).
The mechanism behind muscle contraction is the sliding of filaments in a structure called sarcomere, which mostly involves the presence of actin and myosin filaments.
For muscle contraction to happen, there needs to be a <u>stimulus coming from the nerve that innervates said muscle</u>. This stimulus generates the release of <u>calcium ions</u> that will bind to a protein called troponin and will lead to the exposure of the active site of actin so it can bind to the myosin head. <u>This process requires ATP</u>.

Answer:
Plants and animals release acid forming chemicals that cause weathering and also contribute to the breaking down of rocks and landforms.
