Name the three molecules that are illustrated in Model 1.
FromTheMoon [43]

Answer:

Pentanol, glucose and fatty acid.

Explanation:

Pentanol, glucose and fatty acid are the three molecules which are present in  the given model number 1. In the model, there are three different molecular diagrams for each molecule. The first one is ball and stick model, the second one is Lewis structure and the third one is line drawing method. All diagrams for a same molecule is totally different from another.

The muscles that surround external body openings typically have a ________ fascicle arrangement. parallel convergent pennate cir
HACTEHA [7]
Parallel

In a parallel arrangement, the length of the fascicles runs parallel to the long axis of the muscle. Such muscles are either straplike like the sartorius muscle of the thigh, or spindle shaped with an extended belly, like the biceps brachii muscle of the arm. However, some scientists classify spindle-shaped muscles into a separate class asfusiform muscles.

Pennate

in a pennate pattern, the fascicles are short and they attach obliquely to a central tendon that runs the length of the muscle. Pennate muscles come in three forms:

<span><span>Unipennate, in which the fascicles insert into only one side of the tendon, as in the extensor digitorum longus muscle of the leg. </span><span>Bipennate, in which the fascicles insert into the tendon from opposite sides so the muscle “grain” resembles a feather.
The rectus femoris of the thigh is bipennate. </span><span>Multipennate, which looks like many feathers side by side, with all their quills inserted into one large tendon. The deltoid muscle, which forms the roundness of the shoulder is multipennate.</span></span>

Suppose that an obligate anaerobe microorganism suffered a mutation resulting in the loss of triose phosphate isomerase activity
masha68 [24]
In deprived of triose phosphate isomerase, only one of the two three-carbon molecules produced by aldolase might be used to produce ATP in which only two molecules of ATP would outcome from the metabolism of each molecule to glucose but two molecules of ATP would still be essential to form fructose 1,6-biphosphate, the sub state for aldolase. The net yield of ATP would be 0, a yield incompatible with life.

Imagine a cell with a semi-permeable membrane that is selective to K+ ions only. The internal solution contains 100 mM KCl and t
kompoz [17]

Answer:

C. Nernst equation

Explanation:

The Nernst Equation is used to find the equilibrium potential of an ion.

It tells you only what the equilibrium potential for an individual ion is, not what the summed effect of all ions is on the membrane potential.

The formula for Nernst Equation is:

        E_{ion} = \frac{RT}{FZ} In \frac{[ion]_{out} }{[ion]_{in} }      

where F is Faraday Constant, R = gas constant, 8.314 J/mol K

, T = temperature, in K, Z stoichiometric number of electrons in the reaction,   is the Reduction Potential in V.

Kindly note that, if we have a squid giant axon at rest with normal intracellular and extracellular ion concentrations.  If the membrane permeability to K+  ions is increased, the K+ equilibrium potential (Nernst potential) will stay the same.
