In marine environment, many animals confuse the plastic littering the oceans for food including sea turtles. Once in these animal bodies the plastic accumulates, and the chemicals can cause excess estrogen to be produced, which has led to discoveries of male fish with female sex organs. For sea turtles, the plastic blocks their digestive tract and the food that is trapped releases gases that render them buoyant, and unable to dive for food. The turtle was slowly starving because a single use plastic bag, which she had eaten, was blocking her digestive tract.
The plastic contains destructible and harmful agents that is not good for human and animals health.
The henry's may have damaged and functional hair cells of cochlea in organ of corti.
Hearing and the Cochlea:
- Sound waves that enter the ear go through the external auditory canal before they strike the eardrum and cause it to vibrate.
- The incus receives sound vibrations from the malleus, also called "hammer," which is linked to the eardrum, and sends them on to the stapes.
- The stapes is a framework that moves the oval window in and out. This motion is received by the cochlea, a fluid-filled snail-like structure that houses the organ of Corti, the hearing organ.
- Small hair cells make up the lining of the cochlea. These cells convert vibrations into electrical impulses that sensory nerves then transmit to the brain. the Corti organ, which has four rows of hair cells. On the left, there is an inner row, and on the right, there are three outside rows.
- The stapes first sways against the oblong glass. This causes sound waves to travel into the cochlear fluid and move the organ of Corti.
- Lower frequency sound resonates with fibers towards the cochlea's upper end. Higher frequencies elicit a response from those near the oval window.

The correct answer is letter B, the age range of the skull is less than 10 years old. Teeth are also a form of bone that develop within the skull. Its structure helps archaeologists determine the age of fossils that they dug up from the soil. Children lack some prominent features compared to adults because their bodies are still growing and developing into maturity.
