Answer: C

Explanation: Most of the energy is lost as heat, the rest is used as energy for the animals. But the energy is still in the ecosystem just not in a form that is usable. So, the energy all ways remains the same. Energy can't be destroyed or created only transformed into a new form.

Summary of hearing: Vibrations cause the cochlea’s membrane to shake. This causes ripples in the ____________, bending the _____
mash [69]

Answer:

1) Basilar membrane

2) Stereocilia or hair cells

3) Nerve cells

4) Auditory

5) Temporal lobe

Explanation:

Basilar membrane: located inside of the cochlea which is located in the inner ear. This membrane separates two tubes that is filled with liquid which is also important for hearing.  

Hair cells: Connected to the basilar membrane and they acts as sensory receptors which can catch movements (ripples) in the basilar membrane and pass this message to the neurons.

Nerve cells: One of the main cell types in the brain, which are responsible for signal transfer.

Auditory cortex: This part of the brain is located in temporal lobe and handles the auditory information.

lyudmila [28]

Answer:

Facilitate diffusion by using a transporter

Explanation:

Facilitate diffusion is a type of transport in which a transporter protein is used to transport the molecule across the cell membrane along its concentration gradient. As the movement is along the concentration gradient and does not require energy so it is a type of diffusion.

Glucose travels in the cell by facilitating diffusion because it requires transporter to move across the cell along the concentration gradient. In facilitating diffusion the rate of transport in high than simple diffusion.

Describe the structure of a neuron and explain the function of each of its major parts.
Gwar [14]
A neuron is a nervous system cell specialized in the communication and information processing between the nervous system and the various organs. It is present under different structures (multipolar, unipolar, bipolar ...).It consists of three main parts:
*A cell body also called soma, it is composed of the cytoplasm and the nucleus of the cell that contains the DNA to encode the proteins necessary for the function of the neuron.
*Tree extensions that are also called dendrites, its role is to receive information.
*A single axon with the ability to route information to other cells.
