Answer:
The cell cycle is a repeating sequence of cellular growth and division during the life of an organism. A cell spends 90 percent of its time in the first three phases of the cycle, which are collectively called interphase. A cell will enter the last 2 phases only if it's ready to divide.

Answer:
Day 10
Explanation:
If the number of bacteria increases by a factor of two each day (i.e. it doubles), it will reach 5120 by day 10. At this rate, the colony likely started with 10 bacteria on day one and doubled each day to reach 320 by day 6.
Day 6- 320 bacteria
Day 7- 320×2= 640 bacteria
Day 8- 640×2= 1280 bacteria
Day 9- 1280×2= 2560 bacteria
Day 10- 2560×2= 5120 bacteria

Answer:
The efficiency of the hair dryer is 0.2 or 20%
Explanation:
The efficiency of a machine or any appliance is a measure of the useful work done by the machine when an effort is applied to the machine. The higher the efficiency of a machine, the more useful work the machine does.
Due to the economical and environmental impact of energy production, machines and appliances of high efficiency are being developed and recommended for domestic as well as industrial use nowadays.
In electrical appliances, energy is usually supplied by electrical power units. The higher the efficiency of an electrical appliance, the less power it consumes to do useful work. For a hair dryer which takes in 3000 J of energy per second and transfers 600 J of useful heat energy, its efficiency is calculated with formula below:
efficiency = useful energy / total energy input
Efficiency = 600 J / 3000 J = 0.2
Therefore, the efficiency of the hair dryer is 0.2 or 20%
