Suppose that the concentration of Ca outside the cell is 10 and inside the cell is 0.1 mmol/liter. The Nernst equation at 20oC is: You set the membrane voltage at 58 millivolts using a voltage clamp, and measure membrane current. If Ca is the only ion crossing the membrane, you would expect to see: Group of answer choices 0 current positive charges flowing out of the cell the membrane potential becomes more positive positive charges flowing into the cell

0 current

Explanation:

Ca+ initial concentration is same both inside and outside, therefore there will be zero current on initial membrane. The membrane voltage is set at 58 multivolts which cause current flow in membrane and cell membrane is charged positively.

hormones in blood stream

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
