Answer:
Hearing
Listening
Explanation:
Hearing refers to the vibration of sound waves on the ear drums and the sending of messages to the central auditory system of the brain. The mechanism involve the use of Pinna also known as auricle to gather sound waves which is transferred into the tympanic membrane along the air canal.In the tympanic, sound waves vibrate following the waveform of the sound.
In the middle ear, the ossicles of the middle ear(malleus, incus, stape) assist in the transmission of the vibrations from the tympanic membrane into the inner ear (the cochlea).
The cochlea serve as a mechanical-neural transduction pathway, it helps to transmit sound information via the auditory nerve to the cochlear nucleus in the brainstem.
Listening refers to paying close attention to and making sense of those sounds perceived from the surrounding environment . It is the ability to get the right information without any misinterpretation in the communication process. It is the key to any effective communication.
Answer:
The correct answer is -Sponges lack true tissue but have morevariation in cell type than animas in oter phylum.
Explanation:
Sponges are belong under phylum porifera which have diverse form encrusting sheets to volcano shaped mounds.
The tubes that contain in their body are differ in size from millimeter upto one meter.
The poriferans contain canal system and with help of this, they pump water which enters through a specialed pores called ostia that flows through canal called spongocoel and finally the water exits from their body through oscula.
The sponges show complex organization as their body contain single tube with 2 cell layer thick.
Ascon,leucon,sycons are the level of complexity.
Answer:
C. Nitrogen bases
Explanation:
It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).
Adaptations are
the result of evolution in different living organisms. This process occurs amazingly
through gene mutation but it takes a very long period in time. Adaptation
processes occur to help species survive and thrive in the ecological balance of
life. Structural adaptations are physical features of an organism that adapted
through time. An example of this are the bills of a bird and the fur of bears
that they generally need for their survival; birds for hunting, and bears to
protect them from low climate areas.

Functional or
Behavioral adaptations refer to particular things that an organism or organisms
do to survive. In the example above, behavioral adaptations that birds do is
through certain bird calls and migration, while bears hunt during warmer
seasons and hibernate during winter season. </span>
