1 chromosome
1 chromosome
(before mitosis)
(after replication)
centromere
1 chromatid
per chromosome
2 chromatids
per chromosome
a. Each cell needs a complete set of organelles in order for the cell to work properly
b. Copying the DNA provides more instructions so the cell can work more efficiently
C. Each cell needs to receive a complete copy of the chromosomes in order for the cell to work
properly
yes

Answers

Answer:

C. Each cell needs to receive a complete copy of the chromosomes in order for the cell to work properly

Explanation:

The model in this question depicts the process of DNA replication, which is the process whereby an identical copy of DNA is made. Based on the model in the question, one (1) individual chromosome forms two (2) sister chromatids per chromosome. Each sister chromatid contains the replicated DNA.

This process is very important and must occur prior to any cell division because every cell needs to receive a complete copy of the chromosomes in order for the cell to work properly. For example, each human cell must receive 23 pairs of chromosome or 46 chromosomes in order to function well and this is ensured by DNA replication.

Suppose the stereocilia of one hair cell become permanently bent toward the kinocilium. What will most likely happen as a consequence

Answers

Answer:The options are not given, here are the options from another website.

a. A single pitch will be constantly perceived

B. A single pitch will no longer be perceivable

c. A or B depending on the hair cell's location

d. A or B depending on the bending's direction.

The correct option is d.

A or B depending on the bending's direction

Explanation:

This is because stereocilia are normal bent where there is a shearing force that occur when there is a up and down movements of the basilar membrane . When stereocilia bend towards the kinocilium, it make it depolarizes the cell and lead to the afferent activity to rise up and when the stereocilia bend away from the kinocilium , it hyperpolarizes the cell and lead to a reduction in afferent activity.

The consequences of this are that a single pitch will be noticed, or no pitch will be noticed. This will depend on the direction the stereocilia have bent.

We can come to this answer because:

Stereocilia are cellular accessories that help cells move around.They can curve up or down, generating different but very important effects.If the curvature is made towards the kinocilium, we can notice the formation of a pitch, as the cell becomes polarized.If the curvature is in the opposite direction to the kinocilium, the cell will be depolarized and it will not be possible to visualize the pitch.

In this case, we can state that the consequences of the curvature of the stereocilia will depend on the side towards which this curvature is directed.
