Answer:
Due to its high intelligence.
Explanation:
Scientists think that cuttlefish have the biggest brain to body ratio of all invertebrates that allows it to sense sight, smell, and sound that comes to it in the form of pressure waves. Due to this big brain, cuttlefish are very intelligent so due to its intelligence the scientists thinks that cuttlefish has the biggest brain as compared to other big vertebrates such as octopus.
<span>Under
controlled conditions, sodium bromide and hydrogen peroxide are actually able
to react. However in this experiment, I do not believe that they would react. This
is due to the presence of other compounds which are used in the reaction and
the means by which the compounds were added to the solution. There are actually
a few clues that can tell us whether they are reacting. The most obvious one is
that there would be bubbling due to production of H2 gas. </span>
ANSWER: Last one.
Explanation: Denitrifying bacteria are the agents of this process. These bacteria use nitrate instead of oxygen when obtaining energy, releasing nitrogen gas to the atmosphere. Please let me know if this helps you!
The best and most correct answer among the choices provided by the question is the fourth choice "all of the above."
<span>Bacteria vary from species to species, thus assigning many common traits to bacteria is difficult. Bacterialspecies are typified by their diversity. There are three notable common traits of bacteria, 1) lack of membrane-bound organelles, 2) unicellular and 3) small (usually microscopic) size.</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
I believe the correct answer is B. Vibrate with the frequency of the received sound.
<h2>Explanation:</h2>
The ear is divided into 3 sections: The outer ear, the middle ear and the inner ear. The outer ear is funnel shaped leading into the head to collect sound waves and concentrate it to the middle ear. The middle ear contains the eardrum (tympanic membrane) which vibrates in response to the sound waves.
<h2>Further Explanation:</h2>
The middle ear contains the eardrum(tympanic membrane) which is a special type of membrane that is thin and taught to vibrate to the slightest sound waves. When the sound waves cause the vibration of the tympanic membrane depending on different frequencies, it will cause the 3 bones attached to it ( malleus, incus and stapes) to vibrate at the frequency the membrane vibrated. This motion will cause the round window of the inner ear to vibrate at the same frequency. The round window is connected to a structure called the organ of corti that contains many very sensitive hair cells. The inner ear is filled with fluid including the organ of corti. The vibration of the inner ear is transmitted into this fluid and the back nd forth motion of the fluid will cause vibrations on the hair cells in the base of the organ of corti. These cells are specially adapted and transmit the vibrations as electrical signals to the sensory neurons attached to them. These neurons then will carry the converted sound energy to the brain via major cranial nerves where the brain will interpret these signals as sound waves. Interpretation is continuous and very fast and that is why a person can hear things simultaneously. These hair cells are the ones that get destroyed when listening to loud music making a person go deaf. Bomb blasts and gunfire sound also tear the tympanic membrane and the destroy the sensory cells and this is why many war veterans have hearing problems.
