Answer:
A) Nerve and muscle cells use more energy
Explanation:
Mitochondria are located near sites of high ATP utilization such as in muscle cells and neurons.
In the cells of the heart muscle these mitochondria are located near the contractile apparatus, which is where the hydrolysis of the ATP is carried out to generate the necessary energy in the contraction. In musculoskeletal cells the number of mitochondria is increased between 5 and 10 times when the muscle is exposed to continuous contraction.
In the neuronal cells there is a high workload suffered by the cell and a high energy expenditure
The 4 environmental protectors and their corresponding environmental philosophies are as follows:
1. Conservationist: The conservationist philosophy focuses on the sustainable use and management of natural resources. Conservationists believe in balancing human needs with environmental protection. They emphasize the importance of preserving ecosystems and biodiversity while also considering the needs of communities and future generations. An example of a conservationist approach is establishing national parks and protected areas to conserve wildlife habitats.
2. Preservationist: The preservationist philosophy advocates for the strict protection and preservation of natural environments. Preservationists believe that nature has intrinsic value and should be protected for its own sake, regardless of its usefulness to humans. They oppose any human intervention or exploitation of natural resources. An example of a preservationist approach is the designation of wilderness areas where no human activities are allowed.
3. Environmentalist: The environmentalist philosophy promotes sustainable development and the protection of the environment from human impacts. Environmentalists advocate for reducing pollution, conserving resources, and mitigating climate change. They believe in the interconnectedness of human society and nature, and the need for ecological balance. An example of an environmentalist approach is promoting renewable energy sources and advocating for environmental regulations.
4. Deep Ecologist: The deep ecology philosophy goes beyond the human-centric view of environmentalism and emphasizes the intrinsic value of all living beings. Deep ecologists argue for a radical shift in human values and behaviors to promote a sustainable and harmonious relationship with the natural world. They advocate for a reduction in consumerism, population control, and the recognition of the rights of non-human beings. An example of a deep ecologist approach is the belief that all organisms have an equal right to exist and flourish.
If I had to choose one environmental protector, I would choose the environmentalist. This philosophy recognizes the need for human development while also acknowledging the importance of environmental protection. It promotes practical solutions to environmental challenges and emphasizes the responsibility of individuals and society to take action. By adopting an environmentalist approach, we can work towards a sustainable future where both human needs and the health of the planet are prioritized.Answer:
