Answer:
95%.
Explanation:
Oxygen-hemoglobin dissociation curve:
Oxygen-hemoglobin dissociation curve is basically a sigmoid curve which relates between the saturation of oxygen (SO2) and partial pressure of oxygen in blood (PO2). It shows the affinity of oxygen with hemoglobin at different temperature and other factors. In the oxygen-hemoglobin dissociation curve; saturated oxygen is ploted on verticle axis and partial pressure of oxygen in mmHg on the horizontal axis.
Here in the above scenario at the high altitude oxygen is less and at 80 mmHg, Hb would be 95% saturated.
I. The climate of a place affects the migration of migration of people
Mould growing on a tomato that is sitting on a countertop be used as evidence for the spontaneous generation theory.
<h3>What do you mean by spontaneous generation theory?</h3>
According to the hypothesis of spontaneous generation, the emergence of life things from nonliving materials was both common and predictable. It was proposed that some forms, like fleas, may develop from inanimate substances like dust or that maggots could develop from decomposing human flesh.
In addition to causing postharvest rot during harvest and storage, a gray mold of tomatoes can also spread a number of other diseases, such as damping off and blight. A fungus with a host range of over 200 plants causes gray mold on tomato plants. It will be evidence for spontaneous generation theory.

The whiff of the perfume of Tammy reached the nostrils of Jim through the process of diffusion. The process of diffusion can be defined as the process by which the substances (liquid and gases) move from one place to another from the area of high concentration to the area of lower concentration. The particles of the perfume move from the Tammy's body (high concentration) towards Jim through the air (low concentration).
Hence, the answer is 'Option B - diffusion'.
Answer:
See below
Explanation:
A hypothesis theory and a scientific law are starkly different terms. A hypothesis is at a stage where it is tested in a way that either proves it right or wrong. In the case that it is proved right, it goes on further to be replicated by a several other groups of scientists. If the results/conclusions come out to be correct again, it is known as scientific theory - a more detailed explanation for some phenomenon. Further on, this theory will achieve the status of a scientific law when it has been studied in sufficient detail to give a unifying concept about the phenomenon.
