An experiment is created by a scientist to determine how fertiliser affects sugar cane height. Two fields receive fertilization, but the remaining two do not. Fertilizer Application serves as the experiment's control group.

Fertilizer Application is typically limited to irrigated plantations and varies by region and even by farmer. Fertilizers will work best if used between 12 and 24 months before and after the peak growing season. One year after planting, farmers typically spray 50 kg of urea and 50-100 kg of DAP per acre. Since Casuarina manufactures its own nitrogen with the aid of the bacterium Frankia, it does not require a significant amount of nitrogen fertiliser. In order to prevent this, it is advised to apply 11 kg of urea and 94 kg of superphosphate at moderate level.

The highest frequency sound is detected by Group of answer choices unique hair cells located anywhere along the basilar membrane
Jet001 [13]

Answer:

Option A, unique hair cells located anywhere along the basilar membrane

Explanation:

When ever a high frequency sound wave is perceived by the Organ of Corti, it magnifies. In the magnification process of Organ of Corti, basilar membrane and along with Organ of Corti moves up and down. On the top of Organ of Corti, the hair cells protrudes. With the movement of basilar and tectorial membranes up and down, the hair cells also move laterally.

Hence, option A is correct

A mutation in human ATPase 6 (which corresponds to E. coli subunit a) from leucine to arginine at position 156 may allow the mov

1. There would be an uncoupling of proton translocation and ATP synthesis. 2. ATP synthase would remain sensitive to Fo proton conduction inhibitors.

Adenosine di phosphate (ADP) and inorganic phosphate are used to create the energy storage molecule adenosine triphosphate (ATP) by a protein called ATP synthase (Pi). It is categorized as a ligase since it modifies ADP by forming a P-O link (phosphodiester bond).

A molecular device called ATP synthase. Energy-wise, the production of ATP from ADP and Pi is undesirable, and the process would typically go the other way.

A proton (H+) concentration gradient across the inner mitochondrial membrane in eukaryotes or the plasma membrane in bacteria drives this reaction forward by coupling ATP synthesis during cellular respiration to the gradient.
