. I have two rabbits, one white and one black. The white one has short hair, and the black one has longer hair. Complete the Pun

nett square to determine the offspring of these two bunnies, if the genotypes are Wwll for the white bunny, where white is dominant, and wwLl for the black bunny, where long hair is dominant.
Fill in the top row of the table with the possible gene combinations from one of the bunnies. (you will have two letters - one for hair color and one for hair length).

Fill in the column on the left side of the table with the possible gene combinations from the other bunny. (You will have two letters - one for hair color and one for hair length).

Then complete the rest of the table to show the genotypes of the offspring. (You will have 4 letters - one for the hair color and length from one parent and one for the hair color and length from the other parent).

Put these statements in correct order to understand how hearing works. - Ions enter hair cells - Stapes moves - auditory cortex
OLEGan [10]

Answer: From the question,the correct order of how hearing works is listed below:

--> sound wave is generated from hitting a key on a piano,

--> Incus moves,

--> Stapes moves,

--> Sound wave enters inner ear,

--> Fluid in the cochlea moves,

--> Fluid wave moves across Organ of corti based on frequency,

--> Ions enter hair cells,

--> hair cells bend,

--> auditory nerve transmits the signal to the auditory cortex,

--> auditory cortex recognizes the sounds.

Explanation:

In mammal, two ears are present on each side of the head. It is know as the organ for hearing and balance. The ear is divided into three regions:

--> OUTER EAR: This consists of pinna, ear canal, and eardrum( tympanic membrane)

--> MIDDLE EAR: This consists of the ear ossicles ( malleus, incus and stapes).

--> INNER EAR: This consists of Cochlea (organ of hearing) and semicircular canals (for balance).

To explain further on how we hear sounds, the vibrations of sounds produced from an external source move from the outer ear to the middle and then to the inner ear where the cochlea, the organ for hearing is located.

As sound wave is generated from hitting a key on a piano, the pinna collects the sound waves and directs them into the ear canal. Sound waves impinge on the tympanic membrane and makes it vibrate. This causes the malleus, incus and stapes (in this order) to move to-and -fro at the middle ear region.

In the inner ear region, sound wave enters inner ear as stapes pushes the oval window in-and-out. The vibrating oval window causes the fluid in the cochlea( perilymph) to move to-and -fro. Fluid wave moves across Organ of corti based on frequency. The pressure waves in the perilymph push the membrane separating the upper canal and the cochlear duct to-and-fro allowing ions to enter the hair cells. As a result, the hairs of the sensory cells between these two membranes bend causing nerve impulses to be sent to the brain through the cochlear part of the auditory nerve. Auditory nerve transmits the signal to the auditory cortex which recognizes the sounds.

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct? a. The two
Mandarinka [93]

Question is incomplete ,complete question is as follows :

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

1) The two proteins are very likely related evolutionarily.

2) The differences in the sequences in many instances represent a conservative change (such L for I).

3) The differences in the sequences in many instances represent a nonconservative change (such as D for A).

4) There is no correlation between the two proteins since they originate from very different species.

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

A) Statements 1 and 2 are correct.

B) Statements 1, 2, and 4 are correct.

C) Statements 1, 2, and 3 are correct.

D) All of the listed statements are correct.

Answer:

A) Statements 1 and 2 are correct.

Explanation:

As the Human and sperm whale myoglobin  are very likely related evolutionarily hence option a is correct.

The differences in the sequences in many instances represent a conservative change (such as L for I) hence option b is also correct.

While all the other options are not correct.
