Butterfly whose tail looks like a head

Salts,mostly potassium and sodium are known as electrolytes and the body needs them in very specific amounts for proper function. Any significant imbalance of these levels can even be fatal  if not corrected quickly.

The  normal level of sodium in the body is 135 - 145 mmol/l in the blood while  for potassium it's 3.5 to 5.0 mmol /l.

Loss of salts e.g. due to sweating  may reduce these levels and so drinking plain water may replenish fluid loss but since plain water has no salts, the salt deficit remains and is in fact aggravated by the increase of plain fluid.

But drinking fluid that has  electrolytes  both replaces lost fluids and  and at the same replenishes lost salts keeping the body functioning well .

Final answer:

The process of photosynthesis converts light energy from the sun into chemical energy, primarily stored in the bonds of glucose. This occurs in two stages, the light-dependent and light-independent reactions, using ATP and NADPH as intermediate energy carriers. The glucose can be further metabolized to drive cellular processes.

Explanation:

The process of photosynthesis converts the energy from sunlight into the chemical energy stored primarily in the bonds of glucose, a simple sugar. This occurs in two main stages: the light-dependent and the light-independent (or dark) reactions. During the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into chemical energy stored in molecules of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate).

These energy-laden molecules are then used in the light-independent reactions to convert carbon dioxide from the air into glucose. This process resembles 'recharging' the energy in the morning to be spent throughout the day. Ultimately it takes 18 molecules of ATP and 12 molecules of NADPH to synthesize one molecule of glucose, a total of energy equivalent to approximately 54 ATP molecules.

This glucose molecule can be further combined with or converted into other types of sugars. When the sugars are consumed by cells, the glucose is broken down through a series of complex reactions to extract the energy stored within it. This harvested energy is again stored in ATP molecules, which serve as the primary 'energy currency' within cells to perform various essential tasks.

Answer:

1. Incomplete dominance has occurred

2. A phenotypic ratio 1 Blue : 2 pale blue : 1 white will be obtained.

Explanation:

Mendelian principle states that one allele is capable of masking the expression of another i.e. one allele is dominant and the other one is recessive. Genetic scenarios that have gone against this principle has been observed. One of them is the concept of INCOMPLETE DOMINANCE, which is a case where one allele is not completely dominant over the other, hence, they combine to form a third intermediate phenotype different from both parents.

This is the case in the question where the the blue allele (B) fails to completely dominate the white allele (W), instead it forms an heterozygous plant (BW) with a different phenotype (pale blue) that is a blending of the two parental phenotypes (blue and white). This heterozygote (BW) is formed in the F1 generation.

If the F1 offsprings (BW) are self-crossed, four possible offsprings will be produced using a punnet square. This offsprings will have genotypes: BB, BW, BW, and WW. This depicts a genotypic and phenotypic ratio of 1:2:1 i.e. 1 blue (BB) : 2 pale blue (BW) : 1 white (WW).
