Water is a negative control
B) becomes an adult from a juvenile
Banana and lemon that’s the answer
Answer:
Explanation:
a) the cardiovascular condition is sabacute endocarditis
b) It is caused by a type of streptococcus called streptococcus viridians and transmitted through the opening of the wound
c) rheumatic fever can lead to damage to the heart and this damage allows bacteria to attach itself to the heart. Streptococcus viridians are often caused by bacteria hence there growth can be favorite by rheumatic fever.
d) the nails is used to check the blood stream, and should be check for capillary heamorrhage
e) He would order for BAP- Bacteria Agar plate that is used mostly to classic streptococcal bacteria.
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
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.
