Mercury's seasons are difficult to determine. This is because it has virtually no tilt (0.03 degrees), but a highly elliptic orbit. ... Mercury also has a bizarre rotation, spinning three times (every 53 Earth days) over two rotations around the Sun, making it impossible to tell when one season begins and one ends.
Answer:
A is the answer i had same answer
Answer:
Three types of observational studies include cohort studies, case-control studies, and cross-sectional studies
Answer No 1: False
No, we will not expect the ant population to decrease over time. This is because in our experiment we have included aphids to an area of tree canopy. We expect to see an abundance in the ant population as the population of aphids is increased. We expect these results on the basis of our previous observations.
Answer No 2: True
As seen by our observation that the number of ants increase if we increase the number of aphids, we can deduce that the ants might have a mutualistic relationship with the aphids. As a result, if we remove ants from a tree, the aphids will also decrease from the tree.
Answer No 3: False
Our control in this experiment cannot be two different species of ants as we are studying the mutualistic effects of ants and aphids. Hence, introducing two types of ants will have nothing to do with our hypothesis.
