pls 3-5 sentence and then explain briefly the answer. ty

Answers

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.

Answer
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.

Explain the cell theory

Answers

Answer:

Explanation:

The cell theory basically just tells you that all living things have more than one cell and that cells are made from other cells. It basically just tells you that cells are our foundation for life, without cells we can't live.

For, example, blood cells. If we didn't have blood cells our body's organs can't get the oxygen and nutrients they need to survive. Without blood cells we could get weak or we could just die instantly.

Hope this helps!!!

In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.

The basic tenets of cell theory are that all living things are made up of cells and that cells are the basic units of life. However, cell theory dives deeper than that. ... In other words, everything is made up of cells. Cells are the basic building blocks of organisms and of life.

ribose

Answers

the answer to this question is C

There are two types of nucleic acids depending on the type of sugar units present. The molecule present in the given nucleic acid is deoxyribose. The correct option is C.

What is nucleic acid?

The polynucleotides of very high molecular masses in which the nucleotide units are connected through the phosphate ester bond is defined as the nucleic acid.

The three components present in the nucleic acid are nitrogenous base, a phosphate group and a sugar unit. These are responsible for the biosynthesis of proteins and transmission of inborn character.

The nucleic acid containing 2-deoxyribose as the pentose unit is called deoxyribonucleic acid or DNA. The deoxyribose is a 5 membered sugar molecule which contain an aldehyde group attached to it. The DNA is the main source of genetic information in all life forms.
