C because D stands for delta therefore it signifies change
Answer:
The correct answer would be the use of differential and selective growth medium.
Explanation:
The mixed colonies states of certain species can be developed on the differential and specific media relying on the morphology saw in the general media. These types of selective and differential media will allow certain microorganisms to grow only and not all the rest species present on the media.
It will help in recognizing species present in the mixed colonies present in such a growth medium. Different tests like catalase can be performed to dispose of certain choices not long before the utilization of the differential and particular media.
Thus, the correct answer would be the use of differential and selective growth medium.
Trignonal pyramidal I believe :)
Answer:
exothermic entropy is increased
Explanation:
An exothermic process is one whose rate increases when the temperature is decreased. Hence if a decrease in temperature favours the dissolution of more solute at equilibrium, then the process is exothermic.
Similarly, the dissolution of a solute in a solvent increases the disorderliness (entropy) of the system because of the increase in the number of particles present. Hence once a solute in dissolved, the entropy of the system increases.
To find the annual cost, you need to determine the lamp post daily electricity then convert it into years. Assuming a year is 365 days, the calculation would be: 7 hr/day * 365day/year *100 watt= 255500 watt hour.
Before next calculation, you need to know that kWh mean kilo watt hour which means it was 1000 watt hour. Then the calculation of the costs would be:
255500 watt hour * $0.13 / 1000watt hour= $33,215
