Answer:
The answer is D- Dose-response relationship
Explanation:
A dose-response relationship is an association between dose and incidence in which an increasing level of exposure will either lead to an increase or decrease of an incident or outcome. For instance, in the scenario given the dose or exposure will be the time the infants are put to bed prone while the response is the level of incidence of SIDS (Sudden Infant Death Syndrome).
Bacteria in our gut help to protect us by crowding out some of their dangerous relatives that can cause disease. Other good bacteria have been used in medicine to create antibiotics, and others still are used in food production to make fermented foods (think sauerkraut, yogurt, kimchi and kombucha.)
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⁺⁺.

Explanation:
Forming glycogen as energy storage in the liver is an example of anabolism.
<h3>What is anabolism?</h3>
Anabolism is a metabolic process that consists of the construction and manufacture of more complex molecules from simpler molecules. This contributes to cell growth and energy storage for tissue maintenance.
The process of anabolism can be seen in processes such as the formation of triglycerides or glycogen for energy reserves within cells or in the formation of muscle proteins, given in the sports world.
In these anabolic processes, a lot of energy is consumed since much more complex molecules are being manufactured.
It is a totally opposite and complementary process to catabolism, in which these complex molecules are broken down into much simpler molecules and the release of energy is generated.
For a correct homeostasis of the body, these two processes have to be balanced and work in a <u>complementary way.</u>
Therefore, we can confirm that forming glycogen as energy storage in the liver is an example of anabolism.
