Paleomagnetism is the study of the terrestrial magnetic field during rocks formation or geological processes. The correct option is D. <em>The study of the </em><em>magnetic qualities </em><em>of </em><em>ancient rocks.</em>
-----------------------------
Paleomagnetism is a branch of geology, and refers to the study of the terrestrial magnetic field registered at the moment of a rock formation or during subsequent relevant geological processes, such as metamorphism.
It is based on three basic assumptions:
- Axial geocentric dipole
- Record of the primary magnetic field
- Invariable record in time
The paleomagnetic analysis includes a series of control tools used to verify que acomplishments of these assumptions in the study area.
The correct option would be option <em>D. The study of the </em><em>magnetic qualities </em><em>of </em><em>ancient rocks.</em>

Answer:
A hypothesis that is not possible, or has less strength, to explain how life arose on Earth is that it originated from cells that were delivered by meteorites from outer space (option D).
Explanation:
Although it is a hypothesis that has scientific foundations to be considered, the origin of life coming from organic molecules or cells from space -called Panspermia- has not been completely proven because:
- It provides information on the origin of cells or organic matter, but it doesn't specify how life was formed from them.
- It does not resolve the question of how a cell could withstand a journey through space or endure the high temperatures when a meteorite entered the primitive atmosphere.
These arguments make the hypothesis of the arrival of the first cells from outer space the least accepted today.

C is true.
A is definitely false, since photosynthesis does not occur in petals, but in the leaves (or the portions with green pigmentation)
B is unlikely, depending on which country/state the tap water is from. Anyway, water is more important than nitrogen for the plant to survive.
Hope this helps! :)
In metaphase 1, the chromosomes are arranged on the metaphase plate and are attached onto the spindle fibers. They are in the middle of the cell and are pulled by the the spindle fibers.
Hope this helps.
