Answer:
Serial dilution method
Explanation:
To make a dilution of 10-1 dilution, the culture containing the <em>E. coli</em> broth has to be diluted to make it as 0.1 dilution.
STEPS TO BE FOLLOWED:
- Take the given test tube with 2 ml of <em>E.coli</em> broth culture.
- Take another new test tube with 9 ml of saline solution or distilled water.
- From 2 ml of broth solution, take only 1 ml of culture and suspend in 9 ml of saline or distilled water.
- Now, 1 ml of culture is suspended in 9 ml of saline and the broth is suspended. This constitute 10-1 dilution
- If this 10-1 is again suspended in another 9 ml of water leads to 10-2 dilution factor.
- This methods can be used for both solid and liquid samples like soil or sewage.
Uses of serial dilution:
- Helps in determining the different species of organisms present in soil.
- Organisms (Bacteria) can be distinctly identified from each other since the organisms suspended count will be less when they are dilutes upto 10-10 dilution.
Answer:
The prey with unfavorable characteristics will survive and pass traits to future generations
Yes because every single organism requires dna
The picture doesn't mention mating or nesting - there is not a single mention of those. Therefore we cannot use answers 2) and 4), since we know nothing about them.
The same actually holds for 3) - while there is a mention of the beaks and you can infer the beak size, there is no connection between the beak size and mating activity.
so the correct answer is 1) -the type of beak is matched with the food.
