Photosynthesis
the equation is- Carbon dioxide + water = oxygen + glucose
Answer:
The prolonged electrical depolarization of cardiac muscle cells -that occurs during contraction- is due primarily to the persistent influx of calcium ion
Explanation:
The action potential of the heart muscle is longer with respect to skeletal muscle (around 300 milliseconds), and this is due to the activity of calcium (Ca⁺⁺ ) in the intracellular compartment.
The initial depolarization of cardiac muscle fiber depends on the entry of sodium (Na⁺) into the cell. However, for the action potential to occur and be maintained, Ca⁺⁺ must increase its cytoplasmic levels, which depends on:
- The increase in intracellular sodium induces the release of Ca⁺⁺ from the sarcoplasmic reticulum.
- Calcium entry from the extracellular space through the voltage dependent Ca⁺⁺ channels.
- The entry of extracellular Ca⁺⁺ causes the release of more Ca⁺⁺ ions by the sarcoplasmic reticulum, further increasing its intracellular concentration.
This is how the ion that guarantees the duration of the action potential of the cardiac muscle cell is the Ca⁺⁺.

The previous statement is true because if a substance cannot get into a cell membrane it is assisted via protein channels however if it doesn't need the protein channels then it just flows through the membrane.
The answer is that his blood pressure could increase.
It is known that one of the functions of the kidney is to control blood volume. But, when one kidney is removed, the other one that remained must work for the both. So, the one remained kidney will try to control increased blood pressure, but if the one is not kidney is not enough, it could lead to increase of the blood pressure of the patient.
