many things can lead to an algal bloom in a body of water.
I think the main one you should investigate is the process of eutrophication.
A dead flu virus cell is injected into the body which in turn makes the body recognize the cell so that when an alive flu virus cell enters the body, the body knows what the foreign cell is and can successfully defend against it.
This is because their cells are usually hypertonic to the freshwater they swim in. Their cells will always have dissolved osmotically-active molecules that are critical for cell function. Therefore, osmotically, water will move from the freshwater to the inside of the cells. If not regulated, the cells would swell and lyse. Therefore excess water has to be actively pumped out to maintain cell homeostasis.
Sure! The metaphase stage in the cel is the third step in mitosis. The chromosomes line up in the middle of the cell due to the fact that the spindle fibers pull them towards the middle (the chromosomes are in a single file line). In addition, the spindle fibers connect to the centromeres. Hope this helps :)
Answer: It helps to regulate circadian rhythm
Exposure to natural light during the day helps regulate the circadian
rhythm, which improves sleep pattern. The term circadian rhythm refers to our
biochemical, physiological and behavioral processes in approximately 1 full day
cycle. Circadian rhythm plays an
important role in
controlling when we fall asleep and when we wake up.
During day light, the secretion of melatonin or sleep hormone is
suppress by melanopsin that keeps people awake and alert. Nevertheless, during nighttime,
melanopsin stimulates the release of melatonin to signal sleeping time. Therefore,
this hormone works the entire day and has direct effect on the circadian
rhythm, which acts as a regulator of our biological clock.
