The worm feeds via a "pumping" action in which it first uptakes the fluid surrounding it. Then, it expels the fluid while trapping any bacteria within it. The bacteria are then digested for energy and nutrients.
Explanation:
body temperature and hormone levels. give two examples from the reading of how living things respond to changes in their environment. sweating on a hot day and squinting at the sunlight. ... reproduction, based on genetic code (DNA), grow and develop, obtain and use materials and energy, respond to environment, organized.
Answer:
the correct answer is - a slight difference in factors and their mechanism of transcription such as Nucleotides, polymerase enzyme, and promotor regions.
Explanation:
All types of organism species have exact same nucleotides in their mRNA and DNA. Transcription is also initiated with the similar type of the promotor region in all species.
Slightly differences in any of these or mechanisms can be useful and help to create an evolutionary phylogenic tree or cladogram in various species. The polymerase enzyme is also similar in the various species.
Thus, the correct answer is - a slight difference in factors and their mechanism of transcription such as Nucleotides, polymerase enzyme, and promotor regions.
