Why is turbidity not an accuarte measure of viable bacteria in a culture?
Turbidity measures the cloudiness of a culture, which can be influenced by various factors besides viable bacteria, such as debris or particles in the solution. Viable bacteria may also form clusters or biofilms, which can affect turbidity readings. To accurately measure viable bacteria, other methods such as colony counting or molecular techniques are more appropriate.
How can you tell if there is bacteria growing on something?
You don't have to even check. Everything on the planet is covered in bacteria. It may be growing, or just waiting for the right conditions for it to multiply. And even before you see anything like changes in color or oder, they have already multiplied into the thousands, and even millions. Unless it was just sterilized in a autoclave oven at the right temperature for the correct length of time, it already has bacteria that only time and available food supply that keep them from growing into what you can see or smell, but just remember, they are already everywhere. Technically, the only way to tell is by visual examination, and the only way to do that is with a microscope.
Would it be useful to perform a gram stain on a mixed culture?
The purity of a culture of bacteria is important so it can test on that one type of bacteria. Gram staining can be good so you make sure everything in the streak plate is one color showing that it is gram positive and gram negative.
How do you tell if a bone is still growing?
Bones typically stop growing in length by the end of puberty when growth plates close. A pediatric doctor can assess growth using X-rays to check if growth plates are still open or not. If X-rays show unfused growth plates, the bone is likely still growing.
Where does the growing embryo gets energy?
The growing embryo gets energy from nutrients supplied by the mother through the placenta. These nutrients, such as glucose and amino acids, are essential for the embryo's development and growth.
How can we tell the count of the noof bacteria present in 1 ml of milk?
by growing on suitable media.
How you diagnose if it's viral or bacterial pneumonia?
A sputum culture will generally tell. Bacteria can be cultured, viruses can't.

How can you tell if a mixed culture contains more than one type of bacteria?
You will see different color colonies, irregular ones, or round and even ones on a streak plate.
How do you know a culture is contaminated. What type of method do you use to be certain?
the only way to tell is to do the experiment multiple times and compare the results. also using a control group. an outlier in the results can be from contamination and be an error in the experiment.

How would you change the bacterias plate to best tell if they are ampicillin resistant?
The best test would be to take some of the bacteria growing on the LB plate and streak them on a LB/amp plate. If the bacteria are viable on the LB/amp plate, then they are resistant to ampicillin. If no bacterial colonies survive, then they were not ampicillin resistant.
How can you tell when your breasts have stopped growing?
We stop growing around the age of 21 so by then.
How do you tell when a snake is growing?
