C. Euglena are likely are obtain nutrition via photosynthesis.
Answer:
An electrogenic effect
Explanation:
An electrogenic transport is a process where there is a translocation of net charge across the membrane. E.g of electrogenic channels are Na+, K+, Ca2+, and Cl− channels.
Bee colonies are currently weaker than ever, making bees unable to carry pollin. The carrying capacity of the bees are <em>decreasing</em> because the population of bees are also decreasing.
I would guess that the answer would be :'<span>These organisms dig more shallow burrows than they used to.</span>' If the crabs actively dig burrows, as many crab species do, and a layer of oil has persisted in the lower soil strata, it makes sense that the crabs would be reducing the depths of their burrows to avoid contact with the oil. The other possibility is that the crabs might might migrate to deeper waters, but this is less likely because the crabs would be evolved to utilise the intertidal zone.
