Explanation:
Crop rotation is a farm practice that involves cultivating different species of crops on the same land at different seasons. In other words, the different crops are rotated. Crop rotation is done for various reasons including; improvement of soil fertility, pest and disease control etc.
In this case, a crop rotation of various grains and legumes would be an appropriate solution for the following problems:
- The nutrients in the soil on a farm are being depleted: Legumes are known to be rich in nitrogen and hence add nitrogen to the soil due to the nitrogen-fixing microbes in their roots. Hence, rotating between grains and legumes can help return the depleted nutrients (by grains) to the soil.
- A particular kind of pest is infesting the soil on a farm: Most pests are usually crop-specific, hence, planting only one type of crop can make that soil be infested with a particular kind of pest. However, rotating between crops such as grains and legumes can make a particular pests become scarce or less populated.
Hey friend,
Lets figure this out
One of the mechanisms that increases the amount of genetic variations in a population is a genetic drift.
Answer:
The correct option is B
Explanation:
The <u>biomolecule used in comparing lizards A and B is the mitochondrial DNA while that used to compare the same lizard B to another lizard C is the ribosomal RNA (rRNA)</u>. <u>They should have compared the same biomolecules throughout</u> by extracting the mitochondrial DNA of the three lizards and then proceed to sequence the whole genome of the lizards. After which they can now do a Global alignment (comparison) of the three sequences together. This procedure would have given them a more accurate information on there identity and similarity.
