Answer:
a. plants are preserved as fossils
Explanation:
Through the passing of time, the dead bodies like plants or animals rest in soil, and the cover by different particles, with the time they can be compressed and form a soil layer. If the environment condition changes they get caught in one soil layer. If this process is repeated constantly, so a new soil layer will be formed. So passing the time, different soil layers will have different animals or plants. With the help of isotopes, the scientist can determine the years of each layer.

Answer:
Because of its proximity to Arab lands, many people in the Sahel have adopted Islam.
Explanation:
The Sahel is a region in Africa. It is located between the Sahara Desert and sub-Saharan Africa, being a relatively dry region dominated by the steppe. This region, on its north, has boundaries almost exclusively with Arab dominated countries, so naturally, the people living in the Sahel have had some influence from them.
One of the biggest influences among the people living in the Sahel from the Arabs has been in the form of religion. The majority of the population in the Sahel has adopted Islam and abandoned their native religions. The adoption of Islam has contributed to numerous cultural changes of the people in this region since Islam as a religion has strict rules that people need to follow in order to be considered as Muslims, so numerous native cultural traits have also been abandoned.
Answer: They are not.
Explanation:
When it comes to molecular bonding, a single additional atom can change the characteristics of the compound. This is why Carbon Dioxide is different from Carbon Monoxide even though they both contain only Carbon and Oxygen atoms albeit in different quantities.
In this scenario the compounds described are Hematite which has two iron atoms to three oxygen atoms and Magnetite which has three iron atoms to four oxygen atoms. The presence of the different number of the same atoms made these compounds different.
