lina2011 [118]

<u>Answer:</u>

<em>Farmers definitely use the information above to plan out their crops from one year to next.</em>

<u>Explanation:</u>

Nitrogen is an essential nutrient required for healthy plant growth. Corn is an important food crop and after its cultivation the soil is depleted of its nitrogen. <em>Cultivation of any crop on soils that lack nitrogen will not yield good result.</em>  

Thus the nitrogen in the soil has to be replenished. Soybean is a crop that has symbiotic bacteria living on its roots. <em>This bacteria help in fixing atmospheric nitrogen.</em> Thus the nitrogen level will get replenished.  

Thus cultivating soybean on the land in the period between <em>harvest and sowing of corn would be a healthy practice that increases yield and maintains soil health.  </em>

Match the prokaryotic cell structures to the characteristic of life.
djverab [1.8K]

Answer:

1. Nucleoid: Prokaryotes do not have well defined nucleus. Instead, naked DNA or genetic material is found in the these cells which keeps floating freely in the region of cytoplasm called as mucleoid (nucleus-like). DNA carries the genetic information required for growth, development, metabolic activities and reproduction.

Hence, it must match with b. reproduction: DNA ensures that future generations will be similar to parents

2. Cell wall: Cell wall is the outermost layer surrounding the plasma membrane. It is composed of polysaccharides and is found in bacteria, fungi, and plant cells. In bacteria, it is generally composed of peptidoglycans. Antibiotic such as penicillin acts on the cell wall and creates pores in it which kills the bacteria.

Hence, it can be correctly matched with d. homeostasis: taking an antibiotic, such as penicillin, creates holes in the cell wall of some bacteria, so they lose water and die

3. Flagellum: It is a thread or hair like structure which serves the purpose of locomotion in the cells specially in bacteria, protozoa, spermatozoa etc. In bacteria, it helps in moving in the direction of food and moving away from inhospitable environment.

Hence, it can be correctly matched with e. responding to stimuli: move away from a less hospitable environment or towards a more hospitable environment.

4. Pilus: It is a hair like but rigid structure that protrude from the cell surface of the bacteria. It helps in the process of conjugation by forming a conncetion between cell surface of two bacteria.

Hence, it can be correctly matched with a. reproduction: exchanging genetic material in process of conjugation

5. Ribosomes: Ribosomes serve as the site of protein synthesis in the cell. Bacterial ribosomes are composed of two sub-units with sedimentary constant of 50S and 30S.

Hence, it can be correctly matched with c. maintaining homeostasis: protein is needed for enzymes and repairing structures

6. Cytoplasm: It is gel like material found within the cell (excluding nucleus in case of eukaryotes). All the metabolic activities of the cell generally take place in the cytoplasm of the cell.

Hence, it can be correctly matched with f. homeostasis: using energy, all chemical reactions are performed in the cytoplasm
