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.
D.
This is so since the average person (with activity) stores enough glycogen to last him 12 to 14 hours.
Answer:
B
Explanation:
Carbohydrates and Lipids are both macromolecules and both serve as an energy source and are composed of Carbon, Hydrogen, and Oxygen.
Answer:
a) Emission observed is due to emission of synaptic vessels
b) Yes
Explanation:
<u>a) Proposing an explanation</u>
The emission observed ( the synaptic regions of the neurons remaining fluorescent ) is due to the emission on the synaptic vessels given that FM dyes have lipid-sensitive emission which can be loaded into a recycled synaptic vesicle
<u>b) </u>
The synaptic regions will lose fluorescence when you continue to wash with excess medium, also the more action potentials triggered the more observed emission. hence the increase in the loss of fluorescence is due to the fact that the emissions are not permanent
