A good way to define wilderness is as a landscape not impacted by humans. This means that it is an area where human activities have not significantly altered or influenced the natural environment. Wilderness areas are typically characterized by their pristine and untouched condition, free from human development or modification.

Another way to define wilderness is as a landscape so diverse as to be nearly impenetrable. This refers to ecosystems that are rich in biodiversity and exhibit a high degree of complexity. These landscapes can be challenging to navigate or explore due to their dense vegetation, rugged terrain, or lack of human infrastructure.

It is important to note that wilderness is not an ecosystem in need of development. Instead, wilderness areas are often protected and preserved to maintain their natural state and ecological integrity. Development activities, such as building structures or extracting resources, are generally restricted or prohibited in these areas.

Similarly, wilderness is not an ecosystem in a state of dysfunction. While natural ecosystems can experience disturbances and fluctuations, wilderness areas are typically characterized by their resilience and ability to self-regulate. These ecosystems are often considered to be functioning in a natural and balanced way.

In summary, wilderness can be defined as a landscape not impacted by humans or as a diverse and complex ecosystem. It is important to recognize that wilderness areas are typically protected and preserved to maintain their natural state and ecological integrity. They are not in need of development or in a state of dysfunction. Wilderness areas play a crucial role in biodiversity conservation, scientific research, and providing opportunities for recreational activities that allow people to connect with nature.

Remember, different methods may work better in different situations, so it may be helpful to combine a few approaches to increase effectiveness. Keep in mind that persistence is key, as chipmunks may adapt to certain deterrents over time.

To deter chipmunks from digging in flower pots, you can try the following steps:

1. Remove food sources: Chipmunks are attracted to food, so make sure there are no spilled seeds, fruits, or bird feed in or around your flower pots. Clean up any fallen debris regularly.

2. Use deterrents: There are various types of deterrents you can try to keep chipmunks away. For example, you can sprinkle cayenne pepper or garlic powder around the pots, as the strong scent can deter them. You can also try using predator urine or essential oils like peppermint or citronella.

3. Create barriers: Physical barriers can be effective in preventing chipmunks from accessing your flower pots. Place wire mesh or hardware cloth over the top of the pots, ensuring there are no gaps for the chipmunks to squeeze through. You can also bury a wire mesh or cloth around the pots to prevent them from digging from below.

4. Repellent plants: Planting certain types of plants can naturally repel chipmunks. For example, daffodils, marigolds, and alliums have strong scents that chipmunks dislike. Consider adding these plants to your flower pots as an extra deterrent.

5. Make noise: Chipmunks are startled by loud noises, so placing wind chimes or aluminum foil strips near the flower pots can startle them away. You can also try using ultrasonic devices specifically designed to deter rodents.

6. Keep surroundings tidy: Maintain a clean and clutter-free environment around your flower pots. Remove any potential hiding spots, such as piles of wood or debris, which chipmunks may use as shelter.

Remember, different methods may work better in different situations, so it may be helpful to combine a few approaches to increase effectiveness. Keep in mind that persistence is key, as chipmunks may adapt to certain deterrents over time.

Increasing carbon dioxide in the atmosphere threatens marine life by a. acidifying the ocean.

Increasing carbon dioxide in the atmosphere threatens marine life by acidifying the ocean. This phenomenon, known as ocean acidification, occurs when excess carbon dioxide dissolves in seawater, leading to a decrease in pH levels.

As the ocean becomes more acidic, it poses a significant threat to various forms of marine life, including shell-forming organisms like coral reefs, oysters, and other shellfish. The acidic conditions make it difficult for these organisms to build and maintain their calcium carbonate structures, essential for their survival and growth.

Additionally, acidification can also impact the food chain by affecting the development and survival of small planktonic organisms that serve as a crucial food source for many marine species.

As a result, the overall ecosystem balance and biodiversity of marine environments are at risk.

Answer: B. The temperature of the contents should not change by more than 1°C every 10 minutes.

Explanation: The best criterion for successful development of the container that will insulate the equipment sent to Mars to protect it from extreme temperature changes would be:B. The temperature of the contents should not change by more than 1°C every 10 minutes.This criterion is important because the equipment needs to stay at a constant temperature in order to function properly. If the container can maintain the temperature of the contents within a narrow range over a set period of time, then it can be considered successful in insulating the equipment from the extreme temperature changes on Mars.Option A, saying that the temperature inside the container should reach -73°C at night, is not a reasonable criterion because this would mean that the equipment would be exposed to the same extreme temperature changes as the surface of Mars.Option C, saying that the container should convert electrical energy to thermal energy, is not a criterion related to insulation from extreme temperature changes.Option D, saying that heat should be able to travel easily into and out of the container, is also not a reasonable criterion because it would not provide adequate insulation for the equipment.Therefore, the best criterion for successful development of the container is: The temperature of the contents should not change by more than 1°C every 10 minutes.
