4:
Independent Variable: Photosynthesis
Dependent Variable: Starch
Starch is a product of photosynthesis. Without photosynthesis, starch cannot form. Therefore starch is dependent on photosynthesis.
5:
Independent Variable: Temperature
Dependent Variable: Animal Metabolism
Animal metabolism will only be affected if the temperature of the room changes. Therefore animal metabolism is dependent on temperature.
9:
Independent Variable: Rainfall
Dependent Variable: Thickness of growth rings
The thickness of the tree's growth rings are determined by the amount of rainfall. Therefore the thickness of growth rings are dependent on rainfall.
Answer:
Hydrogen
Explanation:
I think it is showing cellulose cell or DNA as it is inverted 180° for the option there is no option for Phosphodiester bond however I know the answer is hydrogen.
Answer:
All options are correct
Explanation:
Fossils are the remains of organisms (animals and plants) preserved in a rock. Scientists (geologists & palaebiologists) have used fossils to study the diversity of organisms in the past. This is based on their preserved morphological features. For example, several species of foraminifera has been identified in the rocks. Among them, some species are present today whereas others have become extinct.
Similarly, fossils are the indicators of past climate (e.g. temperature) as well. This means, if a specific species can survive at a particular temperature, its presence suggest that particular environment. For example, corals survive in tropical waters at specific depth and sunlight. So, if we find corals fossils, the cliamte of that particular age would be roughly the similar.
In the end, fossils can also provide evidence of orogeny (mountain building) process. These are typically plants fossils which cannot move and their remains are preserved in the folding rocks.
