Tape worms have numerous adaptations to enhance their survival in the hosts.
For example the have anatomical adaptations in the form of scolex with hooks that they use to attach to the host small intestine walls therefore preventing them from being excreted following peristalsis. Therefore, the correct answer is that they posses hooks that they use to attach to the small intestines.
Explanation:
In a food chain, only 10% of energy is transferred from one trophic level to another trophic level. If the energy produced at the producer level is 1000 J, then the energy available at the primary consumer level will be 100 J and energy available at the secondary consumer level will be 10 J.
If there was a sudden drop in temperature after the evolution of the
first living cells, the rate of fermentation would drop due to the
temperature. My prediction would have to include the data, which is on
the graph. The question does not include a temperature to base my
hypothesis on so I would have to conclude that if the temperature
suddenly dropped to 35ºC to -20ºC, that the initial cells would die, and
that the atmosphere and the evolution of cyanobacteria would change
drastically.
The sun's energy drives various processes on earth. One of these processes is photosynthesis in plants whereby light energy is converted into chemical energy by forming carbohydrates from carbon dioxide plus water, which is a process which usually gives off oxygen which animals need to breathe. Another process driven by the sun's energy could be evaporation of water into the air to form water vapour and clouds which then precipitate when cooled off over mountains so is involved in the water cycle.
