The frog dissection is described on pages 148-151 in the book "Speak" by Laurie Halse Anderson.
The most common frog dissection method is to slice a capital "I" shape on the ventral side of the frog. Peel open and pin back the skin, then repeat this for the muscle layer. Remove fat bodies and observe.
It is not necessary, but this can help hold the frog in place more efficiently.
I wouldn't advise using a live frog for dissection as that is cruel. Most schools and universities use fogs that have been purchased and are already dead, stored in a preservation solution.
Chloroform is used in dissection as an anesthetic to sedate animals, making it easier to handle them during the procedure. It helps reduce the pain and stress experienced by the animals during dissection. However, due to safety concerns and ethical considerations, alternative methods of euthanasia and anesthesia are often preferred in modern dissection practices.
This is essentially targeted euthanasia. While the frog is anesthetized, splitting the connection between the brain and spine kills the frog without damaging most of the body.
i don't know u figure it out and stop cheating on your frog dissection worksheet!:[
Because dead body tissue for dissection is preserved with formaldehyde, which when generously portioned onto the skin can cause severe cases of cancer.
After the dissection, clean up by disposing of all biological materials properly as per safety guidelines. Wipe down the dissection tools with a disinfectant solution and wash your hands thoroughly. Clean the dissection area with a disinfectant to ensure proper sanitation.
That would most definitely be the intestines. (I actually just did a dissection today, and had to measure everything.)
Because brain dissection meant certain death for the specimen
