Three Resistors are connected across a 24V battery in parallel. Find (a) Equivalent Resistance

Three Resistors are connected across a 24V battery in parallel. R1= 4Ω R2 = 8Ω R3 = 12ΩFind (a) Equivalent Resistance of the Circuit (b) Current in each Resistor

Two resistors have resistances R1 and R2. When the resistors are connected in series to a 12.0-V battery, the current from the battery is 2.00 A.

Why do flagella form a bundle only when they rotate counterclockwise during chemotaxis?

During Chemotaxis in bacteria with flagella, the flagellar rotation dictates how the cell moves. If the flagella rotate counterclockwise, then they form a bundle at one end of the cell (---O) and... more

What is the mechanism behind "acquired" alcohol tolerance?

I can understand natural variation in alcohol dehydrogenase (ADH) in a population leading to variation in rate of inebriation (after controlling for other variables -- e.g., mass, food consumption,... more

Knockout and knockdown of gene?

Out of curiosity, I got this question whether knocking out (deletion) of a gene on one side and knocking down (RNAi) of the same gene on the other side will affect the cell in a similar manner or... more

Are all functions of a human cell known?

Please bear with me as I'm intruding into your world from a computer science background. In programming, once you have created a program, you know all functions of that program. Thus, 100%... more
