(a)   What is the cause of the plant’s death? 

(b)  What is the cause of the animal’s death?

(c)   Would the survival times for these organisms change if they were placed together in the same jar? Explain your reasons.

Give the affected family members and explain your answer.

In an gel electrophoresis experiment, 0.8% agarose gel was used with 1X Sodium Borate Buffer. What might happen if 1x Sodium Borate Buffer replaced with 20X sodium borate buffer in the electrophoresis.

in agarose gel electrophoresis, low signal intensity was observed in the mixture of different molecular weight molecules. why is this so

How does 10X sodium borate buffer influence electrophoresis instead of 1X sodium borate buffer.

i used to wash my mouth with 70% ethanol and hold it in my mouth for 5 minutes or so. i do it no more but iam concerned about it causing cancer through its metabolite Acetaldehyde.. there ist something strange... i never felt neither the symptoms of excess ethanol nor the symptoms of excess Acetaldehyde, although the mount i used was nearly 30 ml.. but i sprayed it over the upper and lower lip.. could that be because the Ethanol and Acetaldehyde in it evaporate before they reach my mouth or very soon after they land inside my mouth????
