Answer:It is well known that age influences organism mobility. This was demonstrated in vertebrates (such as mammals and birds) but has been less studied in invertebrates with the exception of Drosophila and the nematode Caenorhabditis elegans. Here we studied the influence of age on the mobility of the orb-weaving spider Zygiella x-notata during web construction. The orb-web is a good model because it has a characteristic geometrical structure and video tracking can be used to easily follow the spider’s movements during web building. We investigated the influence of age (specifically chronological age, life span, and time till death) on different parameters of spider mobility during the construction of the capture spiral (distance traveled, duration of construction, spider velocity, spider movement, and spider inactivity) with a generalized linear model (GLM) procedure adjusted for the spider mass. The results showed that neither chronological age, nor life span affected the mobility parameters. However, when the time till death decreased, there was a decrease in the distance traveled, the duration of the construction of the capture spiral, and the spider movement. The spider velocity and the time of inactivity were not affected. These results could be correlated with a decrease in the length of the silky thread deposited for the construction of the capture spiral. Spiders with a shorter time till death built smaller web using less silk. Thus, our study suggests strongly that time till death affects spider mobility during web construction but not the chronological age and thus may be a good indicator of senescence.

Answer:
Another factor can be photosynthesis.
Explanation:
During photosynthesis, plants would give off some oxygen as a waste product. The carbon dioxide would then move from the air into the leaves of the plants through tiny openings in the plant's leaves. Oxygen moves out of the plant's leaf through the same openings.

Why did the mutation that resulted in a long-hair trait in these rabbits become more common in the population?
Mutation that resulted in a long-hair trait in these rabbits become more common in the population because the mutation is inherited and also adaptable to the environment.
What is mutation?Mutation is a sudden change that occur due to changes in gene of an organism. This change can be heritable or transferred from one individual to another.
Mutation can have a rare occurrence and it can be adapted to a particular environment leading to it continuity.
Therefore, mutation that resulted in a long-hair trait in these rabbits become more common in the population because the mutation is inherited and also adaptable to the environment.

Put the following in order to show the path that sound travels through the ear.
mechanical energy is changed to electrochemical energy
sound strikes the eardrum
impulse is sent to by the auditory nerve to the brain
vibrations travel through the malleus, incus, and stapes
sound waves get to oval window
outer ear funnels and focuses sound
hair cells in the organ of Corti detect the wave
Answer:
Explanation:To show the path that sound travels through the ear, the following steps can be arranged in order:
1. Outer ear funnels and focuses sound: Sound waves enter the ear through the outer ear, which includes the pinna and ear canal. The shape of the outer ear helps to gather and direct sound waves towards the middle ear.
2. Sound strikes the eardrum: Sound waves reach the eardrum, also known as the tympanic membrane, and cause it to vibrate. The eardrum separates the outer ear from the middle ear.
3. Vibrations travel through the malleus, incus, and stapes: The vibrating eardrum transfers its energy to three small bones in the middle ear called the ossicles. These bones, known as the malleus, incus, and stapes, amplify and transmit the vibrations to the inner ear.
4. Sound waves get to oval window: The stapes bone in the middle ear transmits the vibrations to the oval window, which is a flexible membrane located in the inner ear. The oval window acts as the entrance to the fluid-filled cochlea.
5. Hair cells in the organ of Corti detect the wave: Within the cochlea, the vibrations of the fluid cause the movement of specialized cells called hair cells in the organ of Corti. These hair cells convert the mechanical energy of the sound waves into electrochemical signals.
6. Mechanical energy is changed to electrochemical energy: As the hair cells in the organ of Corti are stimulated, they generate electrochemical signals in response to the sound vibrations. These signals represent the sound information and are sent to the auditory nerve.
7. Impulse is sent by the auditory nerve to the brain: The electrochemical signals from the hair cells are transmitted to the brain via the auditory nerve. The brain then processes and interprets these signals as sound, allowing us to perceive and understand the sound we heard.
By following these steps in order, we can understand the path that sound takes through the ear, from the outer ear to the inner ear and ultimately to the brain for perception.

What types of waves are sound and light? Explain how they would be classified based on the direction of their particle movement and whether they can move through a vacuum. Use details to support your answer.
Answer:
Longitudinal versus Transverse Waves versus Surface Waves
One way to categorize waves is on the basis of the direction of movement of the individual particles of the medium relative to the direction that the waves travel. Categorizing waves on this basis leads to three notable categories: transverse waves, longitudinal waves, and surface waves.
A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil up and down. Energy will begin to be transported through the slinky from left to right. As the energy is transported from left to right, the individual coils of the medium will be displaced upwards and downwards. In this case, the particles of the medium move perpendicular to the direction that the pulse moves. This type of wave is a transverse wave. Transverse waves are always characterized by particle motion being perpendicular to wave motion.
A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil left and right. Energy will begin to be transported through the slinky from left to right. As the energy is transported from left to right, the individual coils of the medium will be displaced leftwards and rightwards. In this case, the particles of the medium move parallel to the direction that the pulse moves. This type of wave is a longitudinal wave. Longitudinal waves are always characterized by particle motion being parallel to wave motion.
A sound wave traveling through air is a classic example of a longitudinal wave. As a sound wave moves from the lips of a speaker to the ear of a listener, particles of air vibrate back and forth in the same direction and the opposite direction of energy transport. Each individual particle pushes on its neighboring particle so as to push it forward. The collision of particle #1 with its neighbor serves to restore particle #1 to its original position and displace particle #2 in a forward direction. This back and forth motion of particles in the direction of energy transport creates regions within the medium where the particles are pressed together and other regions where the particles are spread apart. Longitudinal waves can always be quickly identified by the presence of such regions. This process continues along the chain of particles until the sound wave reaches the ear of the listener. A detailed discussion of sound is presented in another unit of The Physics Classroom Tutorial.
