____________ is the process in which action potentials in the nerve fiber lead to action potentials in the muscle fiber.There is

then a rapid fluctuation in membrane voltage at the motor end plate, called the end-plate potential.Areas of the sarcolemma near the motor plate have gates that open, moving ions, which causes the ____________ potential that excites the muscle fiber.The process begins with a nerve signal stimulating a voltage-gated ____________ ion channel to open, allowing the ions to enter the axon terminal.The ions stimulate the release of ____________ into the synaptic cleft.

Answer:

Excitation is the process in which action potentials in the nerve fiber lead to action potentials in the muscle fiber. There is then a rapid fluctuation in membrane voltage at the motor end plate, called the end-plate potential. Areas of the sarcolemma near the motor plate have gates that open, moving ions, which causes the action potential that excites the muscle fiber. The process begins with a nerve signal stimulating a voltage-gated calcium ion channel to open, allowing the ions to enter the axon terminal. The ions stimulate the release of acetylcholine into the synaptic cleft.

Amoebae move by crawling over a surface (pseudopodia), which involves _____. A) growth of actin filaments to form bulges in the
KIM [24]

Answer:

the answer is: A) growth of actin filaments to form bulges in the plasma membrane.

Explanation:

Amoebas are unicellular organism that can move on a surface using pseudopodia (false feet). This kind of movement is called amoeboid movement. The amoeboid movement is explained by the Sol-gel theory.  The protoplasm of the amoeba is made of an outer gelatinous layer, and an inner portion made up of plasma sol. The sol-gel theory explains the contraction and relaxation events in the protoplasm of the amoeba that lead to the pseudopodia.

When modeling fisheries: (You may choose one or more answers)
melomori [17]

Answer:

Option A, Fixed quota models are risky because slight miscalculations can result in fish population extinction

Explanation:

Some of the major drawbacks of modelling fishing are as follows –  

a) The fixed quota model is very risky as a miniscule change in attributes can result into extinction of fish.  

b) On the other hand fixed effort harvesting can decrease the risk of fish population extinction

Hence, option A is correct

The doctor also ordered measurement of wally's na+ and k+ levels. how is the adrenal gland related to these?
zepelin [54]
<span>The adrenal gland produces a hormone called aldosterone. Without this hormone, Na+ cannot be reabsorbed from the urine, and K+ cannot be secreted into it. K+ will build up in the blood, and Na+ will be lost in the urine.</span>

The buoyant force in Newtons at a point on the sphere is?
Sergeeva-Olga [200]

Answer:

I calculate the buoyancy force as: Volume of the sphere = Volume of the water displaced (Vdisplaced) = (4/3)πr3. Weight of the displaced water = Buoyancy force (B) = Vdisplaced× density of water.
