A method used by horticulturalists when they rotate the use of fields—planting crops on a particular piece of land for a period
svetoff [14.1K]

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.

In which of the following situations is evolution by natural selection most likely to occur?
Varvara68 [4.7K]

Answer:

b.

Explanation:

Natural Selection refers to the survivability of organisms based on different traits or genes that they have which then get passed on to their offspring. Based on this information we can say that a population of mountain gorillas in which individuals with genes for long hair survive the cold better is the situation in which natural selection is most likely to occur. This is because longer hair in this scenario is a gene that drastically affects the chance of survival for the gorillas and will most likely be passed on to their offspring.
