Answer:
Predator Adaptations
Their mechanical adaptations such as sharp teeth, claws, thick skin and faster speed and superior strength help them to take over the prey. The chemical adaptations include venom, toxins and poison to kill the prey.
I think it is A if not it is B
The system you're looking for should be "digestive system".
This organ system consists of organs such as mouth, stomach, intestines etc.
Basically, how this system works is that it breaks down complex and insoluble food molecules by using enzymes (chemical digestion) , into simple and soluble molecules which can be absorbed by the body and be turned to energy for our body to work. Examples of chemical digestion is such as enzyme lipase digesting lipids into fatty acids and glycerol. In addition, physical digestion (without enzymes) is also used to help speed up chemical digestions. Examples of physical digestion is where we chew the food we eat into a bolus, which can increase the surface area of the food and the enzyme digestion later on can be faster and more efficient.
True... Everything needs energy.
Answer:
I think the results that the researches obtained are that the proteins isolated from extremophilic bacteria functioned normally but the human protein did not functioned at 100° celsius.
This result is obtained because protein produce by the thermophiles is thermostable and produce thermostable enzymes that are structurally and functionally different from enzymes of other organisms because thermophilic enzymes have the capability to withstand high temperature and work properly.
In humans, proteins or enzymes get destroyed in high temperatures because high temperatures denature the proteins. Human proteins or enzymes function well at 37° celsius, and above 41° celsius it starts denaturing.
Therefore human protein will not function at high temperature but extremophile protein will function normally.
