Answer:
Prokaryotes and Eukaryotes are two types of cells with similarities and differences. Eukaryotes are plant cells and animal cells. They are mostly found in multi-cellular organisms. Prokaryotes are usually single-celled organisms and have a tail. Those are the examples that I remember, but there are way more similarities and differences. I hope this helped!!
Answer:
The correct answer will be- Crop rotation
Explanation:
When the growth of a type of crop which uses soil nutrients in abundance and then growing another crop in the same filed led to the decrease in the production of the next crop.
Thus farmers adapted to avoid such farming practices and developed a new practice which allowed the land to become fertile again so that the growth of next crop will not be affected.
The practice involved the planting of a crop on a piece of land then leaving the soil ploughed and unsown for a longer period of time and growing corp on another piece of land allowing the time to restore the nutrient content. This practice is known as "crop rotation".
Thus, crop rotation is the correct answer.

Color is irrelevant, because with time, almost all fossils are a grey tone look
D.) is the better answer between C.) & D.) because layers of the earth are used in the approximation of the time period in which the dinosaur lived
Answer:
Somatic mutations are mutations that occur in body cells, that is the cells that do not make gametes. These mutations are not passed on to further generations; for example, if a mutation that changes a gene in a skin cell would not affect your children because skin cells don't produce gametes.
