In general, why might cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-posi
Zanzabum

Mutation rate of Gram negative bacteria is much greater than that of Gram positive bacteria.

Explanation:

The gram positive types of bacteria responsible for causing diseases in humans. It is called as Gram positive bacteria. Both the bacteria are different in structural and physical properties. It is defined as the group of bacteria’s which positive result in gram stain test.

Gram negative bacteria are the group of bacteria’s which gives negative result to the gram stain test. This classification is done according to the cell wall. The cause of common disease by Gram positive bacteria is our anthrax, diphtheria, etc.

_The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of
Hoochie [10]

Complete question:

The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of the postsynaptic membrane to Na and K

  • True
  • False

Answer:

TRUE

Explanation:

The Acetylcholine neurotransmitter is released from the presynaptic cell by the process of exocytosis.

Once the molecule is in the intercellular space, it moves forward the postsynaptic membrane to join its receptor in the motor plate.

Once the joining has occurred, the receptor acquires a channel shape allowing the ion transference that will make possible the modification of the action potential. Ions traffic will consist of the pass of sodium and calcium to the interior of the cell and potassium to the exterior. Quantitatively, the interchange Na-K is the most significant.

K+ follows a concentration gradient, while Na+ follows an electrochemical gradient. The interchange results in an increase of positive charges in the interior of the muscular cell.

Whenever there is a sufficient number of Acetylcholine receptors are active, the depolarization threshold of the motor endplate is exceeded. This activates an action potential that extends to the rest of the muscle membrane.

DNA replication occurs during which phase of the eukaryotic cell cycle?
wariber [46]

In eukaryotic cells the DNA can be found in the nucleus mainly. so DNA replication takes place in the nucleus during the S phase of the cell cycle.

Also in eukaryotic cells there are mitochondria and chloroplasts (plants) and these have circular DNA and they also get replicated (according to their own mechanism).

Prokaryotic cells don't contain a nucleus. They do not contain DNA in the cytoplasm and thus the DNA replication will take place here.

I really hope this helps!
