A seated normal adult breathes in and exhales every 4 seconds with a change 0.7 liter inhale and exhale. A normal adult will maintain a minimum of 1.35 liters during normal breathing. If you begin timing immediately following an exhale, then write a sinusoidal function that models the situation. How many liters will you have in the lungs at 3.5 seconds? At what time will you have 1.72 liters for the 4th time?

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
