In most cases, one uses tests whose size is equal to the significance level.
i would say by collecting data
I haven't taken biology since my freshman year of high school, so this is kind of a guess. But I know for sure it isn't a solid. So I would go with a gas.
The situation would be that, in a sealed tube, there are 3 to 4 nails inside and a certain amount of calcium chloride was added. After three days, there will be no changes to be observed in the first tube since the oxygen is not enough to initiate a change and there is no presence of water. For the second test, the same situation is made but boiling water was filled in the tube. For this, no changes would still be observed since there is no moisture. For the last test, the same situation as the first but it is filled halfway with water. After 3 days, rust would be observed on the nails. In order for rust to happen, there should be water and oxygen. The oxygen in the early atmosphere of the Earth would react with iron present in the oceans thus producing iron ores.
Answer: d. High biodiversity in the understory.
Explanation:
The taiga or boreal forests are the largest biome in the world. These can be found in the regions of North America, Alaska, and United States. These regions exhibit extreme weather conditions. Typically long winters and moderate to high precipitation. The soil is permafrost and nutrient poor as no new organic matter can be added up to the soil due to it's freezing condition. The plant growth is scanty and biodiversity is low because organisms are incapable of surviving in the harsh weather conditions.
The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.on:
