Answer:
Fossils closer to the surface are younger
Explanation:
Answer/Explanation:
Recall:
Volume of a sphere = ⁴/3πr³
Surface Area = 4πr²
✔️For radius (r) = 1 mm:
Volume = ⁴/3 × π × 1³ = 4.19 mm³
Surface Area = 4 × π × 1² = 12.57 mm²
Ratio of volume to surface area = 4.19 : 12.57 = 1:3
✔️For radius (r) = 3 mm:
Volume = ⁴/3 × π × 3³ = 113.1 mm³
Surface Area = 4 × π × 3² = 113.1 mm²
Ratio of volume to surface area = 113.1 : 113.1 = 1:1
Outer hair cells change their axial dimensions in response to electrical stimulation.
What is basilar membrane motion?
Hair cell stereocilia move as a result of the basilar membrane's movement. The tectorial membrane and the hair cells, which are connected to the basilar membrane, move along with it when it moves, and the stereocilia bend in response to the relative motion of the tectorial membrane.
The hair cells that are linked to the auditory nerve fibers are stimulated by the basilar membrane's movement. While the outside hair cells actively affect the basilar membrane's vibrations, the inner hair cells convert hydromechanical vibration into action potentials.
With each sound cycle, the intracellular voltage of the outer hair cells varies, causing them to lengthen and contract. This increases the organ of Corti's vibration, enabling exceptionally high hearing sensitivity and frequency selectivity.

→ Darwin believed that the need to adapt, in similar words, the changes occruing in the environment caused evolution.
The main cause of evolution, according to Darwin, was natural selection. Natural selection is a process in which a group of organisms with certain characteristics survive and thrive, in comparison to other organisms with different characteristics. This idea basically means that having some characteristics makes you suited for an environment.
And how would that ↑ explain Evolution?
Well, evolution is the change in species that occurs during time. But for you to change, there must be a cause for that change, which is none other than the need to survive, reproduce, etc.
→ As mentioned before, not all characteristics are enough to surive, and hopefully the image pasted below will help you.
Hope it helped,
