Answer: REABSORPTION
Explanation: Reabsorption or tubular reabsorption is one of the processes involved in urine formation,the other two(2) being ultra filteration and and active secretion.
Reabsorption takes place mainly in the proximal convulated tubule of the nephron, nearly all of the water, glucose, potassium, and amino acids lost during glomerular filtration re-enter the blood from the renal tubules,moving solutes out of the filtrate and back into the bloodstream.these solutes that are moved back into the bloodstream goes back into circulation alongside with the blood because it is needed for the normal functioning of the body system and maintanance of homeostasis.
In a situation where tubular reabsorption does not occur as a result of certain conditions like hyposecretion and diabetes insipidus,there will be imbalance of ions in the body as a result of useful ions leaving the body via urine and the body is left with ion deficiency.
When males place their sperm in the females' spermathecae, fruit flies can start laying eggs (a process known as induction). Induced egg laying has the selection benefit of ensuring that a male fly's sperm is utilized for fertilization, which is beneficial for male flies.
- The spermatheca is an ectodermal organ that only develops in Queens and is not present in workers.
- Spermathecae gets sperm from the male during mating.
- Because it assures that a male fly's sperm is used for fertilization, induced egg laying for male flies has this benefit.
Thus from the above points, we can conclude that egg laying in the fruit flies had an adantage.
