Answer:

Prevent infection through vaccination.

Explanation:

The antibiotics are given to the patients against the p[articular infection. The pathogens develop the antibiotic resistance property and the drug is ineffective against the pathogens.

The prevention of the spread of the antibiotic resistance must include the prevention of the disease. The excess use of antibiotics leads to the resistance property in pathogens. The best technique to prevent the infection is the development of the particular vaccination against that infection.  

Thus, the answer is prevent infection through vaccination.

Answer:

Taking antibiotics only on doctor prescription and completing the full course of antibiotics.

Explanation:

Antibiotic resistance occurs when bacteria do not get harmed or killed by a drug which is made against them. Misuse and overuse of antibiotics are the main culprits which induce antibiotic resistance in bacteria.

To prevent the spreading of antibiotic-resistant bacteria antibiotics should only be taken on doctor's prescription. Full course of antibiotics should be done to eliminate all the bacteria which ensures that no bacteria is left to gain antibiotic resistance against the drug.

Antibiotics do not affect or kill virus therefore they should not be taken in viral infection.

A fish maintains its depth in fresh water by adjusting the air content of porous bone or air sacs to make its average density th
Volgvan

Answer:

0.153

Explanation:

We know the up-thrust on the fish, U = weight of water displaced = weight of fish + weight of air in air sacs.

So ρVg = ρ'V'g + ρ'V"g where ρ = density of water = 1 g/cm³, V = volume of water displaced, g = acceleration due to gravity, ρ'= density of fish = 1.18 g/cm³, V' = initial volume of fish, ρ"= density of air = 0.0012 g/cm³ and V" = volume of expanded air sac.

ρVg = ρ'V'g + ρ"V"g

ρV = ρ'V'g + ρ"V"

Its new body volume = volume of water displaced, V = V' + V"

ρ(V' + V") = ρ'V' + ρ"V"

ρV' + ρV" = ρ'V' + ρ"V"

ρV' - ρ"V'  = ρ'V" - ρV"

(ρ - ρ")V'  = (ρ' - ρ)V"

V'/V" = (ρ - ρ")/(ρ' - ρ)

= (1 g/cm³ - 0.0012 g/cm³)/(1.18 g/cm³ - 1 g/cm³)

= (0.9988 g/cm³ ÷ 0.18 g/cm³)

V'/V" = 5.55

Since V = V' + V"

V' = V - V"

(V - V")/V" = 5.55

V/V" - V"/V" = 5.55

V/V" - 1 = 5.55

V/V" = 5.55 + 1

V/V" = 6.55

V"/V = 1/6.55

V"/V = 0.153

So, the fish must inflate its air sacs to 0.153 of its expanded body volume

Please describe the signal transmission across a myoneural junction that allows the nervous system to move the muscles of a foot
Tems11 [23]

The contraction of the muscles (whether at the level of the arms or the legs) and more specifically the muscular fibers of the musculoskeletal system, that is to say organs, in the broad sense of the term, allowing the movement, is normally under the total dependence of the nerves which transmit a nervous command.

This command can be considered as a voluntary order (from the cerebral cortex). This nerve impulse then takes the direction of the spinal cord where it is directed by a series of nerves called relays to route the nerve impulse (order) to the muscles.

Then the nerve impulse propagates along the axon and when it reaches the motor plate it causes the release of a substance called neurotransmitter: acetylcholine. The neuroreceptor, in the motor plate, receives the nerve signal that the end of the axon transmits to it by a chemical mediator. Acetylcholine binds to the receptors, triggering a contraction of the muscle cell.

<em>More precisely, acetylcholine is enclosed in vesicles (a kind of tiny sphere-shaped grains) located within the nervous corpuscles located at the end of each neuron. When nerve impulses (stimulation) reach the presynaptic membrane, acetylcholine is released and diffuses into the synaptic cleft (about 50 nanometers wide) filling it. Acetylcholine will at this time bind very briefly to receptors located after the synapse (postsynaptic) and trigger the opening of sodium channels (followed by their closure and an opening of potassium channels). These channels are tiny tubules allowing the passage of ions (atom having lost or gained an electron). </em>

<em>This results in the propagation of an "electric charge" action potential at the origin of the passage of the nerve impulse, in other words of the order given by the brain or by the autonomic nervous system. </em>

<em> </em>

After this first step acetylcholine is then released and degraded by an enzyme called acetylcholinesterase (AChE) located in the synaptic cleft but also on the postsynaptic membrane. The choline thus released is then recaptured by the presynaptic bodies and reused for the synthesis of new acetylcholine molecules.

Acetylcholine is involved in the control of muscles via neuromuscular terminations and viscera or glands and sometimes both. This is how it intervenes to make also work for certain organs like the heart, the salivary glands, the sweat glands, the bladder, the bronchi, the eyes, intestine etc.

<em>A variety of enzymes called cholinesterases allow the rapid inactivation of acetylcholine. The chemical reaction that causes the contraction of the muscle fiber is a brief phenomenon. Indeed, acetylcholine is very rapidly degraded by cholinesterases. As a result, acetylcholine itself cannot be used in drug form. Nevertheless to circumvent these difficulties other drugs reproduce or prevent the effects of this neuromodulator. These are agonists or antagonists respectively. </em>

The muscular fiber is an elongated cell used in the composition of the muscle, which is a fleshy organ with the property of contracting and relaxing. Each muscle cell is surrounded by a membrane containing a cytoplasm called sarcoplasm with myofibrils which are elongate filaments parallel to the major axis of the cell.
