The major anatomic difference in autonomic reflex arcs is that there are two sensory afferents. True or False

Chemistry

Answer:

False

Explanation:

All organisms have involuntary and rapid muscle responses that develop in some risk situation, which are known as reflexes. Each reflex has an associated reflex arc, a circuit formed by a receiver, which corresponds to a sensitive organ; an afferent path; an integration center; an efferent pathway and an effector; components that bind each other through the synapse.

In mammals, the reflex arc is composed of:

- The receptors, which are nervous structures, which generally correspond to the dendrites of sensory neurons, which transform the energy of a stimulus into a nerve impulse, because they are able to detect specific stimuli, triggering one or more nerve impulses. It is possible to find receptors in the skin, in the sense organs, in the viscera, in the muscles and in the tendons.

- Afferent peripheral nerves, which are formed by axons that drive nerve impulses towards integration centers.

- The integration centers, which are usually the components of the central nervous system, that have association neurons, analyzing the information that the sensitive neurons bring, and then develop a response.

- The efferent peripheral nerves, which are composed of axons that drive nerve impulses from the center of integration to the muscles or glands.

- The effectors, which are those that make the response to the stimuli, being able to perform this response the smooth, cardiac muscle or a gland, when the reflexes are visceral; or striated muscle, when the responses are somatic.

The balanced equation below represents the decomposition of potassium chlorate.
dezoksy [38]
The oxidation number of chlorine in the reactant can be determined by K ion and O ion. K ion is +1 and O ion is -2. And the Cl is +5. The gas has the greatest entropy and the solid has the least. In the production, there are solid and gas. So it has more entropy than the reactants with solid only.

Calculate the ph at of a solution of sodium hypochlorite . note that hypochlorous acid is a weak acid with a of . round your ans
loris [4]

The question is incomplete, here is the complete question:

Calculate the pH at 25°C of a 0.39 M solution of sodium hypochlorite NaClO. Note that hypochlorous acid HClO is a weak acid with a pKa of 7.50. Round your answer to 1 decimal place.

<u>Answer:</u> The pH of the solution is 10.4

<u>Explanation:</u>

We are given:

Molarity of sodium hypochlorite = 0.39 M

pK_a of HClO = 7.50

We know that:

pK_a=-\log K_a

K_a  of HClO = 10^{-7.50}=3.16\times 10^{-8}

To calculate the base dissociation constant for the given acid dissociation constant, we use the equation:

K_w=K_b\times K_a

where,

K_w = Ionic product of water = 10^{-14}

K_a = Acid dissociation constant  = 3.16\times 10^{-8}

K_b = Base dissociation constant

Putting values in above equation, we get:

10^{-14}=3.16\times 10^{-8}\times K_b\\\\K_b=\frac{10^{-14}}{3.16\times 10^{-8}}=3.16\times 10^{-7}

The chemical equation for the reaction of hypochlorite ion with water follows:

                    ClO^-+H_2O\rightarrow HClO+OH^-

<u>Initial:</u>           0.39

<u>At eqllm:</u>      0.39-x                   x           x

The expression of K_b for above equation follows:

K_b=\frac{[HClO][OH^-]}{[ClO^-]}

Putting values in above equation, we get:

3.16\times 10^{-7}=\frac{x\times x}{(0.39-x)}\\\\x=-0.00035,0.00035

Neglecting the negative value of 'x' because concentration cannot be negative

To calculate the pOH of the solution, we use the equation:

pOH=-\log[OH^-]

We are given:

[OH^-]=0.00035M

Putting values in above equation, we get:

pOH=-\log (0.00035)=3.6

To calculate pH of the solution, we use the equation:

pH+pOH=14\\pH=14-3.6=10.4

Hence, the pH of the solution is 10.4

Why glucose and fructose produce same shaped products with phenylhydrazine?
NemiM [27]

During the reaction of glucose and fructose with excess phenylhydrazine to form osazone, only the C-1andC-2 atoms of glucose and fructose participate in the reaction. The rest of the molecule remains intact. Hence, glucose and fructose produce the same osazone.
