<u>Answer:</u>

<em>Reduction of sulfur compounds and the release of hydrogen sulfide is happening here.</em>

<u>Explanation:</u>

Sulfur is an important element in the sulfur cycle. Sulfur compounds can be found on earth in various forms. They can be found in mineral rocks and organic matter. It is the <em>work of bacteria to reduce sulfur</em> compounds and convert them to sulfides.

There are different types of bacteria that reduce various sulfur containing compounds. They are <em>sulfate-reducing bacteria, sulfur-reducing bacteria, sulfite reducing bacteria etc.</em>  In a swamp there is  low oxygen availability and organic matter decays in this condition.

<em>The sulfate reducing bacteria oxidizes the organic matter  and releases Hydrogen sulfide.</em>

pogonyaev

Answer:

25%

Explanation:

T = Hitchhiker's thumb

t = straight thumb

B = Brown eyes

b = blue eyes

The man's genotype is ttBb

The woman's genotype is Ttbb

Make a dihybrid punnett square to find the possible genotypes of the offspring

ttbb is straight thumb and blue eyes. There are 4 out of 16 genotypes with this phenotype so:

Divide 4 with 16 and multiply by 100 to get the percentage of offspring with that phenotype

4 ÷ 16 = 0.25

0.25 × 100 = 25%

Describe the effects of NE and Ach on contractile force that you observed today. Given your knowledge of sympathetic and parasym
Afina-wow [57]

Answer:

The answer is Norepinephrine.

Explanation:

Acetylcholine (Ach) and Norepinephrine (NE) are both chemical substances (neurotransmitters) released primarily by nerve cells and they affect different parts and systems of the body. Acetylcholine mostly targets the muscles and the brain and it is a part of the parasymphatetic nervous system whereas norepinephrine targets the whole body and has an effect that leads to the contraction of muscles and the increase of the heart rate. Norepinephrine is a part of the symphatetic nervous system.

Since the symphatetic nervous system is responsible for the crucial "fight-or-flight" response of our body, it has a more dramatic effect on the muscle contraction. Norepinephrine, being a part of the symphatetic nervous system, should result in a more drastic change in contractile force.

I hope this answer helps.
