It will reduce a plant transpiration. Upper epidermis is a flattened layer of cell that forms the surface of the leaf and makes the cuticle. Lower epidermis: bottom surface layer of tissues which contains the guard cells that form each stoma, which provides transpiration. [ Evert, Ray F; Eichhorn, Susan E.

In media preparation, the culture media needs to be adjusted to ± pH 5.8. Give reasons why it is so and what would happen if the pH is lower than 5 or more than 6.5?

Apart from complete nutritional composition, right and stable pH is another important requirement for optimum microbial growth in culture media. The pH of a culture medium should be suitable to...

Explain why the genetic code would not work if nucleotide bases were arranged in pairs rather than in triplets, to make the coding units.

The reading of code in pairs of nucleotides is insufficient since only 16 different combinations (4²) of the four nitrogenous bases can be made. Given that there are 20 amino...

What information about the Devonian tetrapods leads to the conclusion that tetrapods evolved in the water rather than on land?

The common ancestor of tetrapods vertebrate had fins (with lepidotrichia), scales, gills, and lived in the water.They also had air bladders (air-filled sacs) connected to the back of their throats that...

Why does an endotherm’s metabolic rate increase above the upper lethal temperature? And why does the metabolic rate fall below the lower lethal temperature?

Above the upper lethal temperature, an endotherm’s metabolic rate increases to expend energy that will be used to lose heat. As a result, increased metabolic rate causes sweating that stimulates...

why does the headlines usually use the word magnitude rather than intensity of an earthquake?

The Mercalli Scale is based on observable earthquake damage. From a scientific standpoint, the magnitude scale is based on seismic records while the Mercalli is based on observable data which can be subjective. Thus, the magnitude scale is considered scientifically more objective and therefore more accurate.An intensity scale measures that...

I was told that it is better to use an amphiphilic detergent such as Pluronic f68 rather than mix a hydrophilic one with a hydrophobic one. Why is this the case?

The most valuable in practical terms due to their surfactant properties diphilic - the presence of the hydrophilic and hydrophobic parts. The dual nature of the surfactant molecules promotes spontaneous...
