how are osmosis and facilitated diffusion alike?

Answers

They are related processes that display similarities. Both osmosis and diffusion equalize the concentration of two solutions. They are both passive transport processes, and they don’t require any input of extra energy to occur.

They both use passive transport. they don't need energy to move molecules through the plasma membrane.

proteins expressing color in butterfly wings mutate to improve camouflaging abilities of butterflies

I'm pretty sure it's "proteins expressing color in butterfly wings mutate to improve camouflaging abilities of butterflies" but I'm not sure

Answers

Answer:

proteins expressing color in butterfly wings mutate to improve camouflaging abilities of butterflies

Explanation:

Adaptations occur when the genes of an organism change over time, usually due to external factors.

Beneficial Adaptation

Not all adaptation helps; as stated above adaptations can occur with any genetic mutation, even if it is not beneficial. That being said, beneficial adaptation helps an organism survive and reproduce, so helpful adaptations are the most likely to be passed on. Organisms that have harmful adaptations tend to have fewer offspring, meaning the adaptation does not pass on to the rest of the population.

If an adaptation decreases an organism's ability to survive or reproduce, then it is considered harmful. A beneficial adaptation must improve the life of an organism.

Camoflague

Camoflague allows an organism to hide from other living things, either to hunt or hide from predators. For these reasons, camouflage is considered beneficial. Specifically, butterflies use camouflage to hide and escape from predators that would eat them. This means that camouflage increases the life span of a butterfly. Thus, it must be a beneficial adaptation.

5. Do you drink bottled water? Why or why not? What is its effect on the environment?

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.

The values in the chart are based on the Mohs Scale of hardness, which ranks the hardness of minerals on a scale of 1 to 10. The harder the mineral is, the higher its rating will be. If the material is harder than the mineral, it will scratch the mineral. For example, according to this scale, if a mineral is unable to be scratched by a steel nail, then the mineral has a hardness greater than 6.5.

In three paragraphs, explain the difference between gills and lungs. Give examples of animals with only gills, those with only lungs, and those with both gills and lungs. What are the advantages of having gills, lungs, and both?
HELP ASAP!!!!

Answers

Gills are for fish and salamanders lungs are for mammals and such like that

The main difference between gills and lungs is that gills are the type of respiratory organs specialized to breathe in water, whereas lungs are the type of respiratory organs specialized to breathe in the air. Furthermore, fish use gills while mostly tetrapods use lungs.
Lungfish have a unique respiratory system, having both gills and a lung. It is the only type of fish to have both organs, not only does it help them to survive, but may also be key to the evolutionary origins of the lung. Granddad is the oldest fish we know of anywhere in the world, and there are only six known species around the world.
The advantages of having both lungs and gills gives a better chance of survival above and in water.
