Hi, how do you take care of soil type Termites? What drink, and food to feed? And do you change the soil, if ever?

thanks really helped good for revision before lab exams

This is actually such a good guide, keeping in mind it was made 13 years ago. Some things I would recommend: Give them a deeper substrate, maybe 2-3 inches which will prevent the substrate from drying up too quickly (roly polies need moisture to breathe because they are crustaceans with gills). Try using organic compost, it’s cheap and good for the isopods, potting soil can sometimes contain artificial fertilizers or pesticides. Leaf litter will be the primary food alongside the substrate so make sure to provide plenty of it!

In the 3:25, after adding the acid, the bottle contains some fraction of the initial iodide ions and some iodine molecules. Is that what it makes it look orange?

Is that a brain

Does anyone know how did she get that each 0.1 ml thiosulphate is equal to 1 ppm DO?

Wait, you just stated that the biuret test detects peptide bonds, so your third test cannot possibly be "amino acid positive" it simply confirms the presense of very small peptides. Amino acids on their own would not give a positive result since there would be no peptide bonds.

amazing

What is the uncertainty on the 2000 microlitre pipette?

How to conduct a temperature calibration performance check

I like to go to my backyard and flip over some bricks under my deck. I now have 2 roly poly enclosures filled with rolly pollies, millipedes, and springtails.

This was great, thank you

I am asking my mom if I can get some tonight

Very clear and satisfying

This doesn't work for students with braces because the metal toughens the cheek cells into callouses. Students with braces should be given instructions to scrape higher and or lower than where their braces make contact with their cheeks.

Do they climb out of that plastic tank? I am wondering if I add them to a glass tank if they will escape....

that is great. please tell us how to find different morphology under live microscopic in Schizosaccharomyces Pombe, such as mating , shmoo, zygote and so on , thanks
