denitrifying bacteria
bacteria that break apart cellulose
nitrogen-fixing bacteria
Answer: nitrogen fixing bacteria
Explanation:
Most plants and animals are dependent on nitrogen fixing bacteria for their nitrogen requirements. As they are incapable of absorbing the atmospheric nitrogen directly. The soil bacteria traps the atmospheric nitrogen convert it into forms like ammonia, nitrates and nitrites which are readily absorbed by the plants and some soil borne animals.
When electrons absorb energy they are able to move from their ground states up to excited states. The answer is letter B. an example of this is when you light a match. The molecules of the matchstick are in its ground state. When you flick it on the ground or anything hard, it causes its molecules to move into the excited state and thus causing fire.
The number of orbitals you get per energy level can be found using this formula:
no. of orbitals=n²
Each orbital can hold a maximum of two electrons, the formula would be:
no. of electrons=2n²
Using the given formulas:
no. of orbitals = n² = 2² = 4
no. of electrons =2 * 4 = 8
Answer:
D) yes, because (StartFraction b Over a + c EndFraction)(a + c) = b
Explanation:
just did it on edge 2020
Answer:
The first step is to find the number of moles of OH⁻ that reacted with the HCl. To do this multiply 2.00L by 1.50M to get 3 moles of Ca(OH)₂. Then you multiply 3 by 2 (there are 2 moles of OH⁻ per every 1 mole of Ca(OH)₂) to get 6 moles of OH⁻. That means that you needed 6 moles of HCl since 1 mole of HCl contains 1 mole of H⁺ and equal amounts H⁺ and OH⁻ reacted with each other. To find the molarity of the HCl solution you need to divide 6mol by 1L to get 6M. Tat means that the concentration of the acid was 6M.
I hope this helps. Let me know if anything was unclear.

Explanation:
World war 1 leads to suffer the Americans people a lot .
Young men were forced to go for war which leads to the deplete the financial condition of the house hold. Industry starts to suffer a lot as most of the people who were working has to go for war and man power decreases.
Which leads women to come out of there houses and took job for them so, that they can full fill there needs which starts the new era where woman also start working with men.
