So I was curious about parallel circuit. I first built four branches and only filled them with three light bulbs. Surprisingly, it looks something weird like the picture below. When I filled the fourth branch with a light bulb, everything light equally and even brighter.

Okay, here's what I know. I know that the wire that is outside the branch and connects with the fourth branch, has more current for sure because there is no resistance. However, why the first light bulb got brighter than the second one and so on. Secondly, why is the circuit with 4 light bulb is brighter?

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
