The function of the eardrum in the middle ear is toA. collect the sound waves.
B. vibrate with the frequency of the received sound.
C. amplify the received sound.
D. carry the sound energy to the brain.

Answers

Answer 1
Answer:

The middle ear's eardrum vibrates at the same frequency as the sound being heard, hence option B is correct.

What is an ear?

Many species' ears serve as their sensory organs and as their hearing organs. Its structure may be broken down into three main sections: The outside ear, the Middle ear, and the Inner ear.

Pinna and ear canal make up the outer ear. Skin covers the hard cartilage that makes up the pinna. The pinna's primary job is to collect sounds and direct them into the ear canal. The middle ear may be reached through the eardrum.

The eardrum in the middle ear is what divides it from the outer ear. The eardrum vibrates when sound waves strike it at a specific frequency.

Therefore, the eardrum in the middle ear vibrates with the frequency of the received sound.

Answer 2
Answer:

The function of the eardrum in the middle ear is to vibrate with the frequency of the received sound.

Further Explanation:

Ear is the sensory organ of many organisms which performs the function of hearing.

Structurally it can be divided into three basic parts:

1. Outer ear

2. Middle ear

3. Inner ear

Outer ear consist of pinna and ear canal. Pinna is made up of tough cartilage which is covered by skin. The main function of the pinna is to gather sounds and to move them to the ear canal. Eardrum serves as the pathway that leads to the middle ear.

Middle ear consists of eardrum that separates them from the outer ear. When sound waves hits the eardrum, it vibrates with the frequency of the received sound.

The inner ear changes the vibrations coming from the middle ear to the nerve signals. The inner ear consist of cochlear and semicircular canal.

The cochlea changes the vibrational signal into nerve signals that travels to the brain through the auditory nerve. The function of semicircular canal is to maintain the body balance.

If population size temporarily exceeds the environmental _______, deaths will increase until the population size returns to previous levels.A. carrying capacity
B. density
C. growth factor
D. reclamation

Answers

Correct answer: A). Carrying capacity

The carrying capacity of an environment is the maximum population size of the species an environment can be able to sustain indefinitely, There would be no lack of food, water, habitat and other necessities in the environment.

It is necessary that the environment supports the given species with the natural resource limits, it should degrade the natural, social and the cultural environment. No population can live beyond the environment's carrying capacity.
the answer is A) carrying capacity

Why might a tapeworm have an expanded reproductive system compared to a planarian?

Answers

Tapeworms are hermaphroditic, like the Planaria. The difference between them is that Tapeworms can reproduce sexually, either through self-fertilization or cross-fertilization with another tapeworm, or asexually, by breaking off proglottid segments at the end of the trunk. While the 
Planaria are sexual and asexual only. Sexual planaria possess both testicles and ovaries. One of their gametes will combine with the gamete of another planarian. Each planarian transports its excretion to the other planarian, giving and receiving sperm. Eggs develop inside the body and are shed in capsules. Weeks later, the eggs hatch and grow into adults
