Available oxygen
Available oxygen is the amount of oxygen present at a specific time that can be used in aerobic cellular respiration.
Aerobic cellular respiration is a metabolic process that occurs within the cells of organisms. In this process, oxygen is used in the mitochondria to chemically convert organic molecules such as glucose into adenosine triphosphate (ATP), with the release of water and carbon dioxide as waste products. Aerobic cellular respiration results in a larger amount of energy (ATP) which is used by the cell to perform its activities.

Answer:
The correct answer for the question: This is the strongest intercellular connection between the functional units of life and it is important in cardiac muscle:____, would be: intercalated discs.
Explanation:
Just like skeletal muscle fibers depend on T-Tubules to be able to propagate an electrical impulse between the sarcomeres that form it, so that all respond in syncronization, myocardial fibers also require to do this; otherwise the heart would simply not function. In the case of myocardium, the muscle of the heart, synchronization is vital in order for it to be able to pump blood and meet the needs of the body. Also, like skeletal muscle, these fibers count with a structure that will permit such a thing; intercalated discs. These discs are formed by the ends of myocardiocytes and extensions of plasma membrane, just like in T-Tubules and they play a vital role not just in unifying the entire muscle fiber, but also adjoining muscle fibers. They also play a vital role in action potential propagation.
1. What is the relationship between chromosomes and DNA? The chromosome is a molecule formed by a chain of DNA associated with proteins. Together, they form a group of molecules directly responsible for heredity.
2. What is heredity? It is the biological process where the genes present in a DNA are transmitted by parents to their children, through the division of gametes. These genes carry the codes that form the genotypic and phenotypic characteristics, which allows a similarity between parents and children to occur.
3. What is the role of proteins associated with the DNA molecule that makes up the gene? Proteins are responsible for keeping the DNA line tightly compressed, maintaining the chromosome structure. In addition, they control the activities of the genes present in this DNA molecule, being essential in maintaining heredity.
4. How do chromosomes participate in gene transmission? As mentioned above, genes are part of DNA and DNA is the molecule that makes up chromosomes, in this case, chromosomes are molecules loaded with genes. In the human body, cells have 46 pairs of chromosomes, with the exception of gametes that have half that number. During the reproductive process, the gametes (reproductive cells) divide and produce a new being. The mother's gametes unite with the father's gametes to form a new being. Each gamete has 23 chromosomes, which contain the genes responsible for transmitting the characteristics.
