When the cardiac muscle cell is at rest, the concentration of sodium and calcium is greater on the outside of the cell.
The resting membrane potential (the cardiac muscle cell is at rest) is characterized by more negatively charged inside of the membrane comparing to the outside. The main ions found outside the cell at rest are: sodium (Na+), and chloride (Cl−), and Ca2+ whereas inside the cell it is mainly potassium (K+).
Answer:
the type of molecule-destroying enzyme he used
Explanation:
Frederick Griffith and Oswald Avery were scientific researchers who discovered DNA. Frederick Griffith began the research and Oswald Avery continued his research in 1944 when they made the discovery of DNA. When Avery repeated Griffith's research the experimental variable in Avery's experiment was the type of molecule-destroying enzyme he used.
The forms of pollution that each energy source cause include air, land, water, and even space and noise pollution.
The economy influences energy source choices by the cost efficiency consideration of choosing an energy source. There must be enough money to run the energy production and maintain the energy source.
Location influences energy source choices in such a way that different locations offer different availability of different resources.<span />
The answer is pancreas and intestinal gland. The pancreas mainly secrete amylase, to digest carbohydrates, lipase, to digest fat, and protease, to digest protein. And the intestinal gland mainly secrete carbohydrase, to digest Maltose to glucose, and protease.
