Why do metals conduct electricity? Brainliest!
Already looked it up, so don't try it :)
Answer:
Luckily I did the same thing and it was in my docs
Explanation:
Electricity is the flow of electrical power or charge. Everyday, we use electricity to do many jobs for us from lighting and heating/cooling our homes, to powering our televisions and computers. We get electricity from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources. Electricity can be broken down into some very simple, natural elements. The biggest of which is the atom. Atoms are everything.
Not only that we are made of atoms, but atoms are everywhere. It's a known fact that almost anyone should know.
List at least four consumers from the savannah ecosystem.
small rodents, gazelles, birds of pray, lions there are several :) hope that helped a bit
Here are four consumers from the Savannah ecosystem: zebras, lions, hyenas, and African elephants inhabit the savannah ecosystem, and within it there are a variety of consumers that play important roles in the food chain.
What is the Savannah ecosystem?The savannah ecosystem is a type of grassland ecosystem characterized by tall grasses, scattered trees, and a seasonal climate. It is found in parts of Africa, South America, and Australia, among other places. : Zebras are herbivorous animals that feed mainly on grasses, leaves, and stems. They are adapted to life in the savannah ecosystem and are able to move long distances in search of food and water. Lions are apex predators in the savannah ecosystem, meaning they are at the top of the food chain. They feed mainly on large herbivores such as wildebeest, zebras, and antelopes. Hyenas are scavengers and predators in the savannah ecosystem. They are known for their distinctive laughs, which they use to communicate with each other.
Hence, here are four consumers from the Savannah ecosystem: zebras, lions, hyenas, and African elephants inhabit the savannah ecosystem.

Explain why food chains, food web, and energy pyramids typically do not have more than four levels of consumer?
The reason food chains, food webs, and energy pyramids do not typically have more than four trophic levels is because the energy and biomass decrease when you are going up to the higher levels.
Read the passage. Then evaluate the need for a solution and consider each solution suggested. Which solution do you think is more likely to be successful? Explain your reasoning.
Passage: People traveling to an island accidentally introduced mice into an ecosystem that previously had no mice. The population of mice quickly grew out of control. It started harming populations of native plants and birds. Scientists offered two solutions. One was to introduce cats to the island. The cats could hunt and eat the mice. The other suggestion was to introduce a disease that could infect the mice and reduce their population.
Answer: could be both its up to you will explain each
Explanation: It could be both because if the cats aren't non native cats then that would not really pose a threat. Now let's say it's a different species then I would say it wouldn't be the best idea unless you can control the amounts of cats and send them back to their native country.
In terms of a disease it depends on the effects and if it would affect any other animals or even humans. But if it wouldn't cause any future problems such as a new diseases being spread to humans then I think it would be the safest option.
It is your opinion. I'm writing what I believe

A. Repeat the same procedures many times (have multiple trials).
B. Change the procedures each trial.
Answer:
A. Repeat the same procedures many times
Explanation:
In order to get the most accurate result it is best to do lots of trials. Its like math when you check your work and do it again.
If you change the procedures each trial, you will probably not get the same answer every time. So unless you are looking to check and backup your answer, I wouldn't say B.
