answer is A. Limited resources will
result in stiff competition among
individuals in the population. This will
result in differential
survival across the population because only
the individuals that are able to outcompete
the others will be able to reproduce and pass their genes to the next
generation. This, therefore, will change the allelic
frequency of the <span>population.</span></span>
Answer: After the experiment in step 5
Explanation:
In a scientific investigation, first step is to formulate a question. Second step is to do background research. In third step after background research, a hypothesis is constructed. In order to test hypothesis, an experiment is designed and performed. In the fifth step, data is collected from the experiment and in the last step, conclusions are drawn from the collected data.
The following factors will decrease the amount of oxygen discharged by hemoglobin to peripheral tissues.
A) decreased temperature
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.
