<span>The answer is Acetylcholine. Acetycholine is a chemical messenger, a neurotransmitter that is released by nerve cells in many parts of the peripheral nervous system. It controls the contraction of skeletal muscles or voluntary muscles and also affects the contraction of smooth and cardiac muscle. It binds to the nicotinic ion channel receptors on the muscle cell membrane, causing the ion channels to open. Then calcium ions flows into the muscle cel, initiating a sequence of steps that finally produce muscle contraction. </span>

<span><span> Answer:  </span>Acetylcholine</span>

Acetylcholine<span> is a neurotransmitter, which is a chemical released by the axons of a motor neuron which causes muscles to contract. It has other functions: activates pain responses and regulates endocrine and REM sleep functions. Deficiencies in acetylcholine cause muscle weakness.</span>

If an underwater volcano bubbled additional co2 into the ocean, would this sequence of reactions be driven to the left or the ri
galina1969 [7]

Answer;

-The reactions will be driven to the right

Explanation;

Volcanic eruptions are known to throw huge amounts of gas into the atmosphere, including carbon dioxide that are thought to increase global warming.

They spew lava, carbon dioxide and other elements into the deep oceans. The carbon gets trapped in circulating water, cycled to different regions of the ocean, where it gets caught up in upwelling currents and emitted to the atmosphere.The process can take up to 2,000 years and adds a fraction of the 88 million metric tons of carbon belched out by the volcanoes to the atmosphere.

In photosynthesis, redox reactions ultimately transfer electrons from ______ to ______.
german

The correct answer is: D) H2O… CO2

Redox reactions are reactions of reduction (molecules tend to gain electrons) and oxidation (molecules tend to lose electrons).

Photosynthesis is a set of redox reactions. In photosynthesis electrons are removed from water (H2O) to carbon dioxide CO2 and then used to turn CO2 into organic compounds.  

The first step: Oxygen in water is oxidized (light energy required)

The second step: Carbon in CO2 is reduced; sugar is formed (dark reaction).

A 10-7 is performed on a culture of bacteria in order to perform viable plate counts. From the dilution, *0.1 mL* of solution is
marishachu [46]

Answer:

66 * 10^8 CFU/mL

Explanation:

Given -

a) Number of colonies of bacteria is equal to 66

b) Total volume of the solution is equal to 0.1 mL

c) Dilution factor is equal to 10^{-7}

As we know that

CFU/mL = \frac{N * DF}{V}

Where N is the number of bacterial colonies, DF is the dilution factor and V is the volume

Substituting the given values in above equation, we get -

CFU/mL = \frac{66* 10^7}{0.1} \\= 66*10^8
