D or a those are the best questions..............XD this question though! anyways see yah later and maybe a brainly?
Answer: unfavourable ph condition for the pepsin
Explanation: during digestion, enzymes are needed to aid the process.digestive enzymes are biological catalyst that breakdown large food particles into digestible form .
As biological catalyst, enzymes require an optimum temperature and pH condition.outside this temperature or pH,the enzyme is denatured.
In the stomach, hydrochloric acid is required to convert pepsinogen into it's active form,pepsin.the acid also creates an optimum low pH that pepsin needs to function.
As the food moves to the small intestine,the pH is alkaline and is unfavourable for pepsin to function.
Gause's Competitive Exclusion Principle
The 'competitive exclusion principle' (CEP) states that two species with identical niches cannot coexist indefinitely. ... Gause helped propel ecology by his approach of experimentally testing mathematical models, and his unifying the concept of the niche with resource competition.
Answer:
No
Explanation:
Electromagnetic waves travel slowest in dense matter such as solids. On the other hand, mechanical waves travel quickly through solids. For example, sound travels fastest through solids. This difference is because EM waves do not rely on the movement of particles to travel. Since they require no medium they can travel the fastest in space or other vacuums.
The answer to this question is
B: the theory of evolution
I hyope this is correct and helps
