Question

what are the effects of temperature on planaria regeneration​

Answer 1

Explanation:

At the same temperature, in the low concentration of Fe 3+ from 10 mg/l to 30 mg/l, the regeneration rate of the planarian gradually decreased with the increasing of the concentration of Fe 3+; at the same concentration and different temperature, the regeneration rate of planarian was faster at 20°C and 25°C, but the difference between 20°C and 25°C was small, and the slowest at 15°C, indicating that the low temperature significantly affects the planarian regeneration speed.

temperatures of 25 °C-30 °C substantially increase the speed of development and regeneration, lead to faster manifestation of RNAi phenotypes, and increase reproduction rate without detectable negative consequences for the animal, while temperatures above 30 °C elicit a heat shock response.

The planarians live in fresh water. Water can be obtained from a local freshwater source or bottled spring water can be used. The water should be maintained at a temperature of 21° to 23° C. Water should be changed once a week.

Regeneration in planarians depends on the presence of stem cells called neoblasts.
