ACTIVITY FIVE: The Path From the Ear to the Brain
Goal of this activity: To understand the different structures that allow humans to perceive
auditory stimuli.
Instructions: Read the text, and complete the assignments.
Part One:
Audition depends strongly on the medium - that is, the substance through which sound waves
are transmitted. Draw a picture of, and label the following structures in a diagram that indicates
the path these sound waves travel in order to be perceived by the brain.
Sound wave
Pinna
Auditory Canal
Tympanic Membrano Malleus
Incus
Stapes
Oval window
Round window
Cochlea
Organ of Corti
Auditory Nerve
Superior Olivary Complex Dorsal Cochlear aucleus Inferior colliculus
Medial Geniculate body Auditory Cortex
Helppp pleaseeee
Auditory signals in the form of sound waves pass through the ear canal to the brain where are processed as sound.
What are auditory signals?Auditory signals are sensations or impulses perceives by the ear and sent to brain which transmits it as sound and provides a response to it.
The ability to sense and respond to auditory signals is known as audition which depends on the medium through which the sound waves travel.
The path of audition is given below in order:
Sound wave ---> Pinna ---> Auditory Canal ---> Tympanic Membrano Malleus ---> Incus ---> Stapes ---> Oval window ---> Round window ---> Cochlea ---> Organ of Corti ---> Auditory Nerve ---> Superior Olivary Complex Dorsal Cochlear aucleus ---> Inferior colliculus ---> Medial Geniculate body Auditory Cortex --->Therefore, sound waves travel from the air into the ear canal to the brain where they are processed.

what is the current research saying about evolution?
Answer:
The theory of evolution is based on the idea that all species are related and gradually change over time. Evolution relies on there being genetic variation in a population which affects the physical characteristics (phenotype) of an organism.
why do leukocytes have a nucleus
Answer:
so they can squeeze through blood vessels more quickly.
Explanation:
Some white blood cells have nuclei that are lobed, or separated into pieces, Other white blood cells act as factories making anti-germ weapons and need big nuclei to store the DNA to make those weapons.
what can learn or show us about patterns of evolution?
Answer:
Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.

The main function of cellular respiration is to make ATP, which traps chemical energy in its bonds
Answer:
True
Explanation:
Cellular respiration is the mechanism of breakdown of food materials within the cell to release energy and the trapping of this energy for synthesis of ATP. Therefore, the main purpose is to convert energy stored in the chemical bonds of glucose to energy that the cell can use.

What happens to a species when the environment undergoes a radical change (e.g. due to climate, food source) and the organisms do not adapt? Explain your answer in not less than 3 sentences. May cite a hypothetical; situation to explain the answer.
Answer:
If an environment rapidly changes and an organism cannot adapt it will mostly die out. For example, some birds have long, thin beaks that let them reach insects inside trees. If these insects were to disappear for some reason and seeds became the main food source then the birds with long, thin beaks would not be able to eat. Other birds with different adaptations, like short, strong beaks, would be properly adapted to this new environment. So, this second species would replace the first species.
