7 0

Find # of electrons and draw them onto the Bohr model.

Assuming the atom has a neutral charge, the number of electrons equals the number of protons.  The number of protons is given by the atomic number, 11, so there are eleven electrons.

From the inner "ring" to the outer "ring":

1.  The first "ring", closest to the center of the atom, can take two electrons.

2.  The second "ring", level 2, can take the next six electrons.

3.  The rest of the electrons (three) can fit on the outermost ring.

Which increase the rate of soil formation? Check all that apply.
Rainbow [258]

Answer:

large grain sizes, more precipitation, warmer temperatures.

Explanation:

Soil is the thin layer of material covering the earth's surface and they are usually formed through the process of weathering of rocks. The soil consists of mainly mineral particles, organic materials, air, water and living organisms and they interact with each other.

Large grain sizes, more precipitation, warmer temperatures are the factors that increase the rate of soil formation.

What is nitrogen cycle and, what things need the nitrogen cycle and why is it important?
lapo4ka [179]

Explanation:

So plants need nitrogen to make their proteins (proteins are made of carbon, hydrogen, oxygen, nitrogen and small amounts of sulfer).

Unfortunately, the nitrogen in the atmosphere is inert (unreactive).

But there are still other ways to get nitrogen:

1. Lightning. It causes some of the nitrogen to combine with oxygen, forming nitrogen oxides. These dissolve in rain and are washed into the soil where they form nitrates.

2. Artificial fertilizers. There are literally ammonium compounds and nitrates in those bags that people sell.

3. Nitrogen-fixing bacteria. So there is bacteria in the soil that live in root nodules on plants.

What do they do?? They use nitrogen from air spaces in the soil and combine it with other subsrances to make ammonium ions and other compounds.

4. Nitrifying bacteria. They turn ammonium ions into nitrates, which plants can use again. (so basically they serve nitrogen dish to the plant)

They convert the nitrogen containing substances into BETTER nitrogen containing substances for the plant

5. Denitrifying bacteria. FINALLY these bacteria turn nitrates and ammonia in the soil into nitrogen gas, which goes back to the atmosphere.

And the cycle goes on from the start...

Note that 1-3 are just ways in which nitrogen can be converted into a more reactive form.

I Hope this helps

A trait has two alleles represented by p and q if p 0.22 what is q
pav-90 [236]
q=0,78  
To calculate the frequency of the allele we use the Hardy-Weinberg equation. The Hardy-Weinberg equation is used to calculate the genetic variation of a population at equilibrium. If the alleles are A and a, p is the frequency of the allele A and q is the frequency of the allele a. Hardy-Weinberg equation for alleles A and a:
p² + 2pq + q² = 1
p² is the frequency of the homozygous genotype AA, 2pq is the frequency of the heterozygous genotype Aa and q² is the frequency of the homozygous genotype aa.
p²+2pq+q²=(p+q)²=1
p+q=1
<span>If p=0,22 q=1-0,22=0,78</span>
