Answer:
- the region surrounding the earth or another astronomical body in which its magnetic field is the predominant effective magnetic field.
- the region of Earth’s magnetic field shaped by the solar wind
Explanation:
A magnetosphere is a region around any celestial body producing magnetic field. It is the portion of magnetic field around the Earth which interacts with the charged particles emitting from the sun at high speeds. It is a pear shaped magnetic field region surrounding the Earth. It is shaped by the solar wind.
Thus, the correct answer is b. the region of Earth’s magnetic field shaped by the solar wind
Answer:
B. Solution
Explanation:
According to the question statement, Susan wrote in her notebook that it was a blue liquid. Therefore, from a chemistry point of view, it was a solution and not a heterogeneous mixture. Then, the solvent was evaporated after leaving the solution for 72 hours at the windowsill. The solute (blue color most likely) however was not able to evaporate with solvent and left behind.
Example: if you leave the KMnO4+water solution for a few days, water will evaporate thus leaving behind purple crystals of KMnO4.
This question has an awkward wording, however, the answer is yes.
Obviously, if the rabbit population decreases, so will the coyotes. Because, in assumption, the coyotes rely on the rabbits for food for survival.
Another answer can be yes and no, because if we are talking about the same disease, the disease can probably only target this specific species (rabbit), and the coyotes will not be affected. Or it might spread to any other animal available. Then again, both species are affected and will decrease.

Answer:
There is inverse relationship between DDT use and bald issue reproduction
Explanation:
Dichlorodiphenyltrichloroethane, is commonly known as DDT, which is a colorless, tasteless, and almost odorless, crystalline chemical, an organochlor. Originally developed as an insecticide, it is famous for its environmental impact. DDT was synthesized first in 1874 by the Austrian chemist Othmar Zeidler. The breeding of bald eagles in northwest Ontario rose from 1.26 offspring per breeding area in 1966 to a low of 0.46 in 1974 and then rose to 1.12 in 1981. The DDE residues in the added eggs showed a significant inverse relationship, confirming the effects of toxin on population-level bald head reproduction and the effectiveness of the DDT ban. The recovery from DDE contamination in the bald eagle appears to be much faster than expected.
