1 Peptidoglycan in cell membranes, ether-linked fatty acids, Special transcription DNA

2 Special RNA polymerase, peptidoglycan in cell walls, ester-linked fatty acids

3 Cellulose in cell membranes, ester-linked lipids in cell walls, special transcription DNA

4 Special RNA polymerase, peptidoglycan in cell membranes, chitin and cellulose cell walls

Answer: Option B

Explanation:

There are some of the key markers which states that can differentiate bacteria from other organism.

These markers are special RNA polymerase, ester linked fatty acid and peptidoglycan layer.

The peptidoglycan layer in the cell wall of the bacteria which can be used as a target for all the drugs made as antibiotics.

The bacteria also has special RNA polymerase with four catalytic unit and single regulatory subunits.

The ester linked fatty acid differentiates it from Archae as they have ether linked fatty acid.

What is the volume of 0.25 mol of ammonia gas at 1.00 atm and 273 K? (R= 0.0821 Latm/molK)What is the volume of 0.25 mol of ammo
ICE Princess25 [194]

Answer:

5.6L

Explanation:

Given parameters:

number of moles  = 0.25mol

pressure on gas  = 1atm

temperature  = 273K

Gas constant R = 0.0821Latm/molK

Unknown:

Volume of gas  = ?

Solution:

Using the ideal gas equation, we can solve this problem. The equation is a combination of the three gas laws: Boyle's law, Charles's law and Avogadro's law.

It is mathematically expressed as;

             PV = nRT

where P is the pressure

           V is the volume

          R is the gas constant

          T is the temperature

          n is the number of moles

All the parameters are in the appropriate units and we simply solve for the volume of the gas;

                1 x V = 0.25 x 0.0821 x 273

                      V  = 5.6L

Onions are stem modifications of which of the following types?
Ira Lisetskai [31]

Answer/Explanation:

Onions are stem modifications of bulbs. Onions grow during a cold weather, but forms bulbs when the weather is warm. Onions can either be grown using seeds or through their bulbs. That is why, the stem modification of onions are bulbs. Tuber is from potatoes, whereas corm is from crocuses and gladioli.

Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from hap
vekshin1

Answer:

Phenytoin and ethosuximide are drugs that slow the recovery of the sodium channel during the inactivated state.

That is to say, they prolong the inactivation state of the channel, thus generating that in this way the neuron remains in resting potential and the action potential causing the epileptic attack is not triggered.

On the other hand, these drugs, according to the bibliography of the book "Golan, 3rd Edition, Principles of Pharmacology" have a use-dependent affect capacity, this means that those sodium channels that have more activity will be more affected, in this way Not only is epileptic shock avoided, but if the same happens independently in any neuron, it will not be able to propagate the action potential to its neighboring neurons, therefore the surrounding neurons will not be stimulated and will not be fulfilled. with the sudden rapid discharges that are the most dangerous in some cases of severe epilepsy.

It is important to understand that these drugs affect the ion channels responsible for exciting neurons, that is why by inhibiting them, a constant rest of these neurons is promoted, and they are unable to generate abrupt discharges and dissemination of the electric charge. among them generating epileptic shocks.

The ions in neurons are in charge of indicating or modulating the different neuronal states, if they are inactive, open or closed, they will directly affect the membrane potential, that is, the positive or negative charge of the neuron's membrane.

Explanation:

In order to finish completing the question, these drugs are excreted through the p450 protein, that is why if this excretion system becomes saturated because another drug is consumed that is excreted in the same way, these antiepileptics will remain longer in use. blood and in the body, generating a greater effect and enhancing adverse effects on the central nervous system.
