grandymaker [24]2 years ago
3 0
Cyclins drive the events of the cell cycle by partnering with a family of enzymes called the cyclin-dependent kinases (Cdks). A lone Cdk is inactive, but the binding of a cyclin activates it, making it a functional enzyme and allowing it to modify target proteins.

Located on the basilar membrane are(is) the ________, containing hair cell sensory receptors for the sense of hearing.
mojhsa [17]

Located on the basilar membrane are(is) the <u>organ of Corti</u><u> </u>containing hair cell sensory receptors for the sense of hearing.

The organ of Corti is also called basilar papilla which is a complex form of neuroepithelium composed of hair cells sensory receptors and supporting cells. In addition to these sensory and supporting cells, the organ of Corti also consists of a tectorial membrane. Endolymph which is a potassium-rich fluid surrounds the organ of Corti. The organs known as scala tympani and scala vestibule are present under and above the basilar papilla respectively.

The function of the organ of Corti is to generate electrical signals based on the sounds and transmit these signals to the brainstem through the passage of auditory nerves.

If someone could dig a safe tunnel through the earth how long would it take to free fall to the center?
Reptile [31]

Answer: A scenario often presented to introductory physics classes is that of a "gravity tunnel" — a tube drilled from one side of the Earth to the other through the planet's center. The answer taught for nearly a half-century for how long a fall through such a hole would take was about 42 minutes and 12 seconds.

Explanation: However, solar and lunar gravity, which also perturb orbiting satellites, would eventually pull you into the tunnel wall anyway [source: Darling ]. Strike a chord: Fun fact: A straight line from any point to any other point through the planet would take the same amount of time to fall through like a tunnel through Earth's center.
