What happens in a decomposition reaction? O A. Two or more substances combine to form one substance. B. Two ions trade places. O C. Larger compounds break down into two or more smaller compounds O D. The charges of the atoms change.
Answers
Answer:
C. Larger compounds break down into two or more smaller compounds.
Explanation:
During a decomposition reaction, the bonds between the atoms break down in the starting substance. The atoms then rearrange to form new bonds, resulting in new substances with properties different from the starting material.

Which of the following is not true concerning cover crops? a. They prevent soil erosion b. They can fix nitrogen in soil c. They are sold as cash crops d. They add organic matter to soil Please select the best answer from the choices provided A B C D.
Answers
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.
What are the cover crops used for?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.

Fruits and stem have lenticels. Give reason
Answers
Answer:
because lenticels permit the exchange of gases between the environment and the internal tissue spaces of the organs
Fruits and stems have lenticels. These are the specialized cells which permit the exchange of gases between the atmosphere and the plant body.
What are lenticels?A lenticel is a specialized tissue which is a porous tissue. It consist of cells with very large intercellular spaces in the periderm of the secondarily thickened organs in the plant body and the bark of the woody stems and roots of the dicotyledonous flowering plants.
Lenticels can be easily seen as they are visible on the surface of fruits, such as mango, apple, and avocado. Lenticels permit the exchange of gases between the external environment and the internal tissue spaces of the organs such as stems and some fruits of the plant body. These cells permit the entrance of oxygen gas into the plant and simultaneously the output of carbon dioxide and water vapor from it.
