In the ear, the sound waves enter through the auditory canal and hit the eardrum (tympanic membrane). The eardrum amplifies the sound and the waves move on to the middle ear, where three bones called the ossicles (malleus, incus, and stapes) amplify the sound further and vibrate. Then, the sound waves go to the cochlea where tiny hairs and other receptors turn the sound waves into a nerve impulse. This impulse is sent to the brain via the auditory nerve and interpreted by the brain.
Answer:
•Climate Change- the change in the earth atmospheric enviorment, due to pollution and human activity.
•Ocean acidification- due to carbon dioxide dissolving in the ocean, carbonic acid forms, causing high acidity; this can cause problems for wildlife.
•Invasive Species- do not belong to a specific environment, location, etc. and are believed to be a cause of certain enviormental damage.
• Increasing Human Population- the increase of human life; overpopulation.
• Eutrophication and Algal Bloom- Algae don't have enough nutrients, and thus causes depleted oxygen levels in the ocean, and generally poor water quality for sea life.
• Deforestaion- the decrease in forest trees, usually caused by human activity.
• Threats to biodiverity- this includes overpopulation, pollution and climate change, usually the cause of human activity.
• Overexplotation of Resources- overusing natural resources, this can be bad especially if the resources take a long time to reproduce.
Explanation:
because vaccine injected to them produces antibodies which fight against the bacteria
An organism in its niche within an ecosystem is similar to a baseball player in his position on the baseball team.
<h3>NICHE:</h3>
Niche in biology refers to the specific role or position of an organism in its ecosystem or habitat.
The niche of an organism is specific or particular to that organism and this enables it to adapt and survive in its environment.
This explanation shows that niche can be likened to a baseball player in his specific position on the baseball team.
