Arrange the following structures in the order in which they vibrate when a sound wave enters the ear. eardrum (1) endolymph (2) ossicles (3) oval window (4) perilymph (5)

Eardrum→Ossicles→Oval window→Endolymph→Perilymph

Explanation:

The Ear is the organ of hearing and in mammals balance. In mammals the ear is often described as having three parts- The outer ear, the middle ear and the inner ear. the outer ear consist of the pinna and ear canal. The middle ear include the lymphatic cavity and the three ossicles. The inner ear sits in the bony labyrinth, and contain structures which are key to several senses: The semi circular canal which enable balance and eye tracking when moving. The Utricle and saccule which enable balance when stationary and the cochlea which enable hearing.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
