Nitrogen returns to the atmosphere through a process called denitrification. <u>Option C.</u>

<u />

Denitrification is the process of converting nitrate to nitrogen gas thereby removing bioavailable nitrogen and returning it to the atmosphere. Nitrogen is returned to the atmosphere through the activity of organisms known as decomposers. increase. Some bacteria are decomposers breaking down the complex nitrogen compounds found in dead organisms and animal waste.

Denitrification is a microbial process that reduces nitrates and nitrites to gaseous nitrogen primarily nitrous oxide N2O and nitrogen N2. Various microorganisms can denitrify. Denitrification is a response to changes in oxygen O2 concentration in the immediate environment. Atmospheric nitrogen is utilized by certain microorganisms through a biological fixation process. Alone or in symbiotic relationships with some plants and animals microorganisms can fix atmospheric nitrogen.

lora16 [44]

Answer:

Eubacteria and Archaebacteria

Explanation:

Prokaryotes are single-celled organisms that do not have a nucleus

Eukaryotes are typically multicellular, but definitely do have a nucleus

Eubacteria and Archaebacteria DO NOT have nuclei

Fungi (think mushrooms) and Protists do have nuclei- and belong to the Eukaryote group- which means they DO have nuclei

Why are plants important to the carbon water and nitrogen cycles?
dezoksy [38]

Answer:

The carbon and water cycle I know, but I can't help with the nitrogen cycle. Sorry.

Explanation:

Carbon cycle - The role that plants play in the carbon cycle is that they take in our carbon dioxide and put out oxygen, which we breathe. So we give the plant air and they give us air.

Water cycle - The role that plants play in the water cycle is when it rains, the plants absorb some of the water in their roots, thus making them strong and therefore helping the ground not become a mud hole.

Sorry that I can't help with the nitrogen cycle. But I hope what I was able to help you with helps!

In a population of cats, the phenotypic frequency of black cats is 91%, and the phenotypic frequency of white cats is 9%. Assumi
Talja [164]

Answer:

1. Allele frequency of b = 0.09 (or 9%)

2. Allele frequency of B = 0.91 (0.91%)

3. Genotype frequency of BB = 0.8281 (or 82.81%)

4. Genotype frequency of Bb = 0.1638 (or 16.38%)

Explanation:

Given that:

p = the frequency of the dominant allele (represented here by B)  = 0.91

q = the frequency of the recessive allele (represented here by b)  = 0.09

For a population in genetic equilibrium:

p + q = 1.0 (The sum of the frequencies of both alleles is 100%.)

(p + q)^2 = 1

Therefore:

p^2 + 2pq + q^2 = 1

in which:  

p^2 = frequency of BB (homozygous dominant)

2pq = frequency of Bb (heterozygous)

q^2 = frequency of bb (homozygous recessive)

p^2 = 0.91^2 = 0.8281

2pq = 2(0.91)(0.9) = 0.1638
