B) increased pH
C) decreased amounts of DPG
D) increased tissue PO2
How oxygen is being transported?
About 97% of the oxygen used during breathing is delivered by red blood cells in the blood, while the remaining 3% dissolves in plasma. The pigment hemoglobin, which is found in RBCs, is what gives blood its red color. According to the partial pressures of oxygen, carbon dioxide, H+ concentration, and temperature, oxygen attaches to hemoglobin to create oxyhemoglobin. Up to 4 oxygen molecules can be carried by a single hemoglobin molecule. The optimum circumstances for the synthesis of oxyhemoglobin include low temperature, high H+ concentration, and oxygen partial pressure. In the alveoli, these criteria are satisfied. But in the tissues, the circumstances are different, and as a result, oxygen is separated from oxyhemoglobin.

Answer:
The skeletal muscles connect to the bones and work with connective tissue at the joints to allow for movement. The muscles connect to the nervous system and allow initiation of movement through nerve signals to and from the brain. The bones and muscles are supported by connective tissue, which plays an integral role in structural support.
c. Resistant bacteria have survived and reproduced at a greater rate than nonresistant bacteria
Explanation:
The antibiotic is no longer effective as it was 20 years ago because the resistant bacterial have survived and reproduced at a greater rate than the non-resistant bacteria.
- The antibiotics have specifically designed to exterminate the disease causing bacteria strain from the body.
- While at that point in time, it is potent and does the work. Along the line, it will cause the structures of some other strains to change.
- This will lead to the development of resistant breeds with time.
- The resistant breed will then be able to survive the onslaught of the antibiotics making it not a good fit.
