How are cells affected by the movement of water?

Answers



Cells are affected by the movement of water through osmosis. Osmosis is a natural phenomenon in which molecules move from lower concentration to higher concentration. This movement depending on the solution type of the environment can either shrink or burst or oversaturate a cell

Which of the following best supports the statement that mitochondria are descendants of endosymbiotic bacteria-like cells?Mitochondria fossils are older than the oldest fossilized eukaryote.
Mitochondria can survive indefinitely when removed from a eukaryotic cell.
Mitochondria have their own set of DNA molecules.
Mitochondria can produce ATP molecules.

Answers

Mitochondria are descendants of endosymbiotic bacteria-like cells because D. Mitochondria can produce ATP molecules.

  • Mitochondria simply refer to the membrane-bound cell organelles that generate chemical energy that is used in the biochemical reactions of cells.

  • The theory of endosymbiosis simply explains that chloroplasts and mitochondria are descendants of ancient bacteria-like organisms.

  • It should also be noted that the chemical energy that is being produced by the mitochondria is stored in adenosine triphosphate (ATP) which is a small molecule where the chemical energy is stored.

In conclusion, the mitochondria perform most of the cellular oxidations that occur in animals. It's also useful in producing most of the ATP that can be found in cells.

For each of the 4 environmental protectors, determine the environmental philosophy or philosophies it would fit in. If you had to choose one environmental protector, which would it be and why?

Answers

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:
