Why does physarum polycephalum branch out like a plant or fungus?

How does the tapeworm’s action inside the shrimp increase its chances of survival?
igomit [66]

Answer:

Infected shrimps have high level of lipids, fats and  antioxidants

Explanation:

When the brine shrimps get infected with parasite then their ability to survive in toxic water increases. Brine shrimps infected with tapeworms usually change their color and become red.  

The mining activities in surrounding area introduced harmful and toxic chemicals such as arsenic that has made the water habitat toxic for shrimps. Now it was found that shrimps with parasite increased in number as compared to shrimps without parasite. This is so because worm infected shrimps have more droplets of lipids — fats — in their tissues that helped them to sock away arsenic. Along with lipid fats infected brine shrimp also produced more antioxidants than the non-infected ones and hence the stress on cell reduced.

A high amylase (ha) individual and a low amylase (la) individual eat identical crackers at the same time. which individual's blo
alexandr402 [8]
I think it is the individuals with high amylase levels. After ingesting starch, the individuals with high amylase levels will have lower blood glucose levels relative to the ones with low amylase levels, which is related to the early release of insulin by the high amylase individuals. Amylase enzymes secreted in saliva help break down starches into simpler sugar molecules that can be absorbed into the blood stream.
