The parasympathetic nervous system is characterized by the location preganglionic neurons and the short postganglionic axons near the organs they innervate. The preganglionic neurons would originate in the spinal cord or the brainstem while the postganglionic neurons would lie outside the CNS.

Answer:

if crossing over does not occur, the products are parental gametes. If crossing over occurs, the products are recombinant gametes. Meaning they are mixed.

Explanation:

If crossing over doesn't occurs then you wouldn't really mix the 2 parental alleles so you couldn't have a genotype without mixing.

Sorry if im wrong!

When a singly ionized potassium ion moves through a channel in the membrane passing from the outside to the inside, what is the
Korolek [52]

The magnitude of the work done by the electric field of the membrane is <u>W = 1.28 × 10⁻²⁰ Joules</u>.

We start with the necessity to take into account a value for the voltage present there in order to solve this problem by first considering that the membranes have two layers, one internal and one external, each responsible for producing a potential difference between the two levels.

As a result, in order to find a solution, it is necessary to take into account the potential difference between the two surfaces. In this instance, we'll assume a particular value for the load, but the recipient is free to substitute a different value if they prefer.

The product of the potential difference and the charge is used to define the work that an electric field performs. The charge of the potassium ion will be equal to that of its electron, so,

q = 1.6 × 10⁻¹⁹ Coulombs

Then the Work would be:

W = Vq

Here,

v = Potential difference

q = Charge

The 80mV potential difference we will have is quantified as follows:

W = (80mV (1V/1000mV))( 1.6 × 10⁻¹⁹ C)

W = 1.28 × 10⁻²⁰ Joules is the amount of work that the membrane's electric field has produced.

Scientist determine that abundance of apple aphids on leaves of 120 apple trees. the autumn leaf color of the apple tree varied.
Kobotan [32]
The answer is bold dependent and underline independent. In addition to biology laboratory examination, independent variable is the most important variable in which this variable is manipulated in what the investigator differs in the experiment. Dependent variable in the experiment, one variable will be stately or calculated or experimental in reaction to experimental situations.
