Answer:
By using specialized external systems.
Explanation:
To maintain homeostasis, unicellular organisms grow, respond to the environment, transform energy, and reproduce.
Answer: The second factor that leads to fluidity is the nature of the phospholipids themselves. In their saturated form, the fatty acids in phospholipid tails are saturated with bound hydrogen atoms; there are no double bonds between adjacent carbon atoms. This results in tails that are relatively straight
The communication skill that has been applied by the student nurse that shows effective learning is through nonverbal communication. This type of communication involves using body languages, facial expression or direct contact towards another individual in a way of communicating. In which this is an effective communication that is done in the scenario above.
It’s a mix of two materials!
Answer:
E. contraction of the stapedius and tensor tympani muscles.
The acoustic reflex protects the ear from intense sounds by <u>contraction of the stapedius and tensor tympani muscles.</u>
Explanation:
Although there are two middle ear muscles (tensor tympani and stapedius) in humans, only the stapedius muscle contracts in response to sound.
Contraction os stapedius causes a change in the axis of rotation of the stapes footplate, thus increasing the immitance of the middle ear system. This change in conductivity through the middle ear can be measured indirectly as changes in acoustic immitance. This reflex results in decreased sound transmission to trochlea.
Hence the answer is E. contraction of the stapedius and tensor tympani muscles.
