Why are frogs said to have two life's

Answers

Frogs are said to have two lives because when they hatch, they turn into little fish-like creatures known as pollywogsthat live underwater. This is considered their first life. Then, the pollywogs mature into tadpoles and start budding limbs. Finally, after a while in this stage, their arms and legs will become fully developed, making them frogs and they will leave the water to live the rest of their life without needing water as their primary environment. This is considered their second life.

Explain (not just list) where you observe reflection, refraction, and absorption of light in your everyday activities

Answers

Reflection: you look in the mirror.
Refraction: You put a straw in a glass of water, and it looks like it broke.
Absorption: If you have a black sweater and you wear it out in the cold, the black sweater is going to hold in heat better than a lighter sweater because the black sweater absorbs light.

Answer:

Your eyes

Rainbows

Light bending in a glass of water

Glasses

Camera lenses

Object dislocation in water

Binoculars

Basically anything that has to do with light bending in a medium (glass, plastic, water, oil...) of any kind. Just look around, you'll find many examples :)

Explanation:

Reflection: you look in the mirror.

Refraction: You put a straw in a glass of water, and it looks like it broke.

Absorption: If you have a black sweater and you wear it out in the cold, the black sweater is going to hold in heat better than a lighter sweater because the black sweater absorbs light

Rob measures the solubility of three different salts in water at 22°C. Which type of graph should he use to display his data?

Answers

The correct answer to this question is a line graph. If Rob needs to create a graph that is able to display the combination of two different values - in this case, level to which the salt has dissolved and time taken - and he needs to have more than one result included, then a line graph is the way to present this.

Explain why some scientific theories are changed over time​

Answers

Answer:

A common misconception is that scientific theories are rudimentary ideas that will eventually graduate into scientific laws when enough data and evidence have been accumulated. A theory does not change into a scientific law with the accumulation of new or better evidence.

What effect might global warming have on earths inhabitants?
Please help!tysm ;)

Answers

Here are few of the things that scientists think may happen as the temperature rises. Some of them are already happening: Glaciers melting - Many glaciers are already melting and shrinking throughout the world. If the temperature increases they will continue to melt. This will cause animals that rely on glaciers such as polar bears and other species to become extinct. Ocean levels will rise - As the glaciers melt, the ocean levels will rise. This could cause flooding in cities located near the coast. Migration of animals - Animals will migrate to cooler spots as their old habitats get too warm. This could upset the food chain and put some species in danger of extinction. Extreme weather - Some scientists think that warming will fuel more powerful hurricanes as well as more droughts and flooding in different areas of the world. Change in ecosystems - cold weather biomes such as the tundra will shrink, while desserts will continue to expand. Hope this helped :)
