In the agricultural practices cover plants are grown for the enrichment and the protection of the soil. They are not harvested to be sold as cash crops.
<h3>What are the cover crops used for?</h3>
Cover crops are grown in the agricultural land parts to maintain the soil fertility and quality so that the land will be safe from the invasion and attacks of pests and weeds.
They are generally grown after the reaping of cash crops and help in soil binding by preventing erosion from the water runoffs.
These plants help in fixing the nitrogen content of the soil and help the soil to remain fertile and nutrient-rich. They increase the organic and the mineral compounds to the soil profile and enriches the soil quality.
Therefore, option c. they are sold as cash crops is incorrect.

All of the following (corals, jellyfish, and sea anemones) have only one opening into their digestive system, except roundworms, which have more than one.
Hello,
The practice of leaving the Stalks of crops in the grouns is known as <span>no-till farming.
Hope this helps

Scientific method is a continuous process. This process starts with the observation of a certain phenomenon. Based on what is observed, a hypothesis is develop to describe this phenomenon. This hypothesis is then tested by experiments where the results of these experiments either confirm or contradict the developed hypothesis.
If the hypothesis is contradicted by the results of the experiment, then another hypothesis is developed and tested for either confirmation or contradiction.
Based on this, any question that cannot be tested and studied experimentally cannot be solved using scientific methods.
<h3><u>Answer;</u></h3>
- Prokaryotic only: <u><em>nucleoid
</em></u>
- Eukaryotic only:<u><em> nucleolus, lysosome, mitochondria
</em></u>
- Both: <em><u>plasma membrane, ribosomes, flagelia</u></em>
<h3><u>Explanation;</u></h3>
- <em><u>Prokaryotic cells are those cells that lack nucleus and other membrane bound organelles, unlike eukaryotic cells which contain a membrane bound nucleus and membrane bound organelles such as mitochondria, and lysosomes.</u></em>
- <em><u>Prokaryotic cells lack the nucleus and nucleolus, but instead contain a nucleoid which contains the genetic materials of the cell.</u></em>
- <em><u>Eukaryotic cells on the other hand contain a well defined nucleus, that contains nucleolus and highly complex genetic material.</u></em>
- Despite the differences, <em><u>they both share a number of organelles and characteristics such as plasma membrane, which regulates the movement of substances in and out of the cells, ribosomes, sites for protein synthesis, and also flagella, for locomotion.</u></em>
