Answer:
1. There's air pollution, water pollution, noise pollution, and light pollution. The worst pollution is air pollution because it can cause severe health problems like respiratory diseases or even cancer.
2. Fossil fuels are resources that are formed from the remains of dead plants and animals. An example would be coal, oil, and natural gas. These fuels are used to generate electricity, power vehicles, heat homes and buildings. Yes, there many other energy sources that can replace fossil fuels.
3. One way to prevent factories from dumping waste water in rivers and oceans is to implement stricter regulations and penalties for those who violate them.
4. One of the best ways to reduce the amount of garbage is to reduce, reuse, and recycle.
5. Yes, I drink bottled water because it's more water to drink from a bottle and its effect on the environment is recycling and being reused.
1. Pollution can be of many types such as air pollution, water pollution, noise pollution, and land pollution. In my opinion, air pollution is the worst because it affects people's health and can cause breathing problems, heart diseases, and even cancer. Discussing this issue in a group can help us understand different perspectives and find solutions to reduce pollution.
2. Fossil fuels are non-renewable sources of energy that are formed from the remains of dead plants and animals. Examples of fossil fuels include coal, oil, and natural gas. They are used to generate electricity, fuel vehicles, and heat homes. However, they are a major contributor to air pollution and climate change. Fossil fuels can be replaced by renewable sources of energy such as solar, wind, and hydro power.
3. Factories dumping waste water in rivers and oceans can have a negative impact on aquatic life and the environment. To prevent this, factories can treat their waste water before discharging it into the environment. Governments can also enforce strict regulations and penalties for factories that violate environmental laws.
4. To reduce the amount of garbage, we can follow the three R's - reduce, reuse, and recycle. We can reduce the amount of waste we generate by using reusable bags, bottles, and containers. We can also compost organic waste such as food scraps and yard waste. Recycling can also help reduce the amount of garbage by turning waste into new products.
5. I try to avoid drinking bottled water because it generates a lot of plastic waste that can take hundreds of years to decompose. Plastic waste can also harm wildlife and pollute the oceans. Instead, I use a refillable water bottle and fill it with tap water. Tap water is safe to drink in most developed countries and can be a more sustainable choice.

While savannas and temperate grasslands are both types of
grasslands and share many characteristics, they also have
some differences. Compare them below by writing each
characteristic in the correct location. You will use each only
once.
• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answers
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

Answers
Answer:
Genetic engineering is a type of biotechnology that involves manipulating the DNA of an organism to create desired traits. This can be done through various techniques, such as gene editing or gene splicing. One benefit of genetic engineering is that it can be used to create crops that are more resistant to pests and diseases, which can increase food production and reduce the need for harmful pesticides. However, one risk of genetic engineering is that it can lead to unintended consequences, such as the creation of superweeds or the loss of biodiversity.
For society, genetic engineering can also have both benefits and risks. One benefit is that it can be used to create medicines and vaccines that are more effective and targeted, which can improve public health. However, one risk is that it can lead to unequal access to these treatments, as they may be expensive and only available to those who can afford them.
In terms of the environment, genetic engineering can also have both benefits and risks. One benefit is that it can be used to create crops that require less water or fertilizer, which can reduce the environmental impact of agriculture. However, one risk is that it can lead to the spread of genetically modified organisms (GMOs) into the wild, which can have unknown effects on ecosystems.
Overall, while genetic engineering has the potential to bring many benefits, it is important to carefully consider the risks and unintended consequences before implementing it on a large scale.

How do animals and plants play a role in the water cycle?
Answers
Answer:
Plants, especially trees, contribute to the water cycle via transpiration, where water evaporates from the surface of their leaves. Close to 10 percent of all water enters the water cycle due to plant transpiration. Animals contribute to the water cycle via respiration, perspiration and urination.
Explanation:
Without the water cycle, freshwater lakes and rivers would not exist and living things would not be able to thrive on land far from the ocean. do not just benefit from the water cycle -- they participate in it. The contributions of living organisms to the water cycle are vital.
Plants, particularly trees, contribute greatly to the water cycle because of the processes they use to . Unlike animals, which get their energy from food, plants convert sunlight into usable energy through photosynthesis. Plants also and through their roots.
When a tree absorbs water, it travels throughout its branches to its leaves. Needed for photosynthesis, trees and plants cannot get the energy they need from the sun without water. During photosynthesis, some excess water from the surface of the leaves, becoming water vapor. The water vapor in the process of travels into the atmosphere and becomes part of the water cycle, in the same way as evaporated water from lakes, rivers and oceans.
At first glance, it may not seem that plant transpiration contributes that much to the global water cycle. But plants and trees supply a large amount of the world's water via this process. About 10 percent of all water enters the cycle via plant transpiration.
Though they don't contribute as much as plants, animals still supply some of the water present in the water cycle. Animals contribute water mainly through , .
When animals breathe, their warm lungs fill with air. Inside the lungs, some of that air condenses into water vapor. When an animal exhales, they release more water vapor than they breathed in, which adds to the water present in the water cycle. Many animals also . When droplets of sweat evaporate from the surface of an animal's skin, they take a bit of the animal's body heat with them. They also turn into water vapor and enter the water cycle, just like water evaporating from plant leaves.
When animals consume water, they to expel the excess, which then then evaporates and re-enters the water cycle. Even animal dung contains some water which may re-enter the cycle in the same way. Though trees represent the biggest living contributors to the water cycle, animals also play a valuable role in recycling Earth's water. Without living creatures, the water cycle’s effectiveness diminishes, and less water recycles. Though often not included in the explanation of the water cycle, all living organisms contribute to it in their distinctive ways.
