The part of the cell membrane that acts as a barrier are the Hydrophobic tails!
Answer:
Hybrid Offspring Degeneration Phenomenon...
Explanation:
This happens in hybrids because of their improper alignment of chromosomes. It is rare but when two hybrids mate, they already have defected copies of chromosomes of their parental specie. That why the offspring from hybrids are mostly born dead and degenerate totally in embryonic stage.
ah! All thanks to the cell membrane!
The cell membrane contains phospholipids that are amphiphilic (polar - water attracting and non-polar - water repelling) in nature. That's why the cell membrane allows non-polar materials to pass through but not polar materials. (if you're learning junior science you really don't need to know this!) The polar materials require proteins found on the cell membrane called protein channels or carrier proteins to pass through. (their names are pretty self-explanatory!)
All the best!
Krill in this food web is the primary consumer. Since the producer of the food web is the phytoplankton. Removing them from the food chain cuts the supply of food for secondary consumers such as seals, and whales. This disrupts the whole Antartic ecosystem since there will be a large amount of phytoplankton but not enough food for secondary consumers. This because secondary consumers are not able to eat phytoplankton due to their microscopic size. Only krill are able to feed on them and have the maximum energy gain from them.
