When you store a petri plate, which side should be on the bottom? Why?
Homework Answers
The petri plate should be stored upside down which means the bottom should be on the upper side because when you store a petri plate, condensation takes place and if the plate is not inverted then water droplets will fall on the colonies and hinder the development. Evaporation of water from media can cause media dryness and this can affect microbial growth but when plates are stored in inverted position, this decreases the rate of water evaporation and results in better microbial growth.

Describe when and why you should use PHP (as a server-side programming language). Why a client-side programming language (like JavaScript), not enough? Also, is it generally safe to keep credentials like the Database passwords in PHP source code? Why? Compare that to doing the same thing in JavaScript.

A hot plate consists of a flat electrical resistor, which is adiabatically insulated on one side and on the other side is in contact with a ceramic layer of 1 cm thickness and 30 W/mK thermal conductivity. The hot plate is operated inside a fume hood, where air at 20 C flows over producing convective cooling on the top surface of the heater with a heat transfer coefficient of 15 W/mK The plate generate a total heat transfer rate of...

A parallel-plate air capacitor is to store charge of magnitude 290 pC on each plate when the potential difference between the plates is 40.0 V. If the area of each plate is 6.80 cm^2, what is the separation between the plates? Express your answer with the appropriate units. If the separation between the two plates is double the value calculated in part (a), the capacitor to store charge of magnitude 290 pC on each plate? Express your answer with the...

Which culture should be able to survive the longest exposure to UV (SA or BS)? Why? 7. Do you expect to see a difference between the growth on the side of the plate that was under the index card and the side that was open? If so, explain what you expect to see. 8. Some cells have a means of protecting themselves against radiation. Can you name a few structures that might help protect a cell from UV light?
