Answer:

Denitrification = bacteria convert nitrates into nitrogen gas.

Denitrification occurs when nitrogen is removed from the soil and this happens when bacteria concert nitrites back to Nitrogen gas.

Nitrification = Bacteria convert ammonia to nitrites and nitrates.

Nitrification is the process by which bacteria concert ammonia made from ammonification into useful organic compounds like nitrites.

Nitrogen fixation = bacteria break down waste products and return nitrogen to the soil.

Nitrogen fixation is when bacteria return nitrogen to the soil by breaking down waste products that fall into the soil.

Ammonification = bacteria convert atmospheric nitrogen to ammonia.

During ammonification, bacteria converts nitrogen compounds to Ammonia or Ammonium.

Assimilation = Plants and animals take in and use nitrogen compounds.

Assimilation then occurs when plants take in these nitrogen compounds and use them. Animals will get these compounds by eating the plants.

Identify the isolation mechanisms described using the drop-down menus. Differences in courtship or other behaviors prevent matin

lana [24]

Answer:

First, let's add the missing piece of information

Identify the isolation mechanisms by labeling either Geographical, Behavioral, Temporal, or Anatomical from the drop-down menu

The correctly identified mechanism is

1. Behavioral

2. Geographical

3. Temporal

4. Antomical

Explanation:

Differences in courtship or other behaviors prevent mating.- our answer is Behavioral

(Behavior isolation is the term used to describe reproductive isolation as a result of variations in courtship behaviours between the members of the same species occupying the same region).

Species can no longer interact because they are separated by physical boundaries.- it is Geographical

(Geographic isolation is seen in situations where the two populations of the same species get isolated by a geographical barrier such as mountain, island or river. This results in an inability to breed between the two populations as they become distinct new species).

Species do not interbreed because they breed at different times. this is definately Temporal.

(Temporal isolation is a form of reproductive isolation due to mating at separate times and seasons among two populations of the same species).

Species cannot physically mate due to genitalia or gametes being incompatible. And the correct answer is Antomical.

(Anatomical isolation

It is observed in situations when two populations of the same or distinct species cannot interbreed due to physical features such as genitalia and gametes formed in the organisms that make them uniquely separated).

Yes! this is the right answer. I just solved this question and its CORRECT.

Imagine that a given species has a gene for hair color (B = dominant brown, b = recessive white) and a gene that controls hair l

serg [7]

Answer:

Phenotypes: All Brown Hair Color and All Short Hair Length

Genotypes:

Homozygous dominant hair color and homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).

Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)

Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)

Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)

Explanation:

Hair color :

B = dominant brown

b = recessive white

Hair length :

S = dominant short

s = recessive long

The dihybrid cross between parents with the genotypes:

BBSS × BbSs

If BBSS self crossed; we have the following traits= BS, BS, BS, BS

If BbSs self crossed; we have the following traits= BS, Bs, bS, bs

The dihybrid cross is as follows:

BS BS BS BS

BS BBSS BBSS BBSS BBSS

Bs BBSs BBSs BBSs BBSs

bS BbSS BbSS BbSS BbSS

bs BbSs BbSs BbSs BbSs

Phenotypes = All Brown Hair Color and All Short Hair Length

Genotypes include:

Homozygous dominant hair color and homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).

Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)

Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)

Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)
