How does DNA fit inside the nucleus of a cell?
1. DNA is a short molecule
2. DNA is tightly coiled into chromosomes
3. only part of the DNA fits in the nucleus
4. each nucleus contains only one gene
Answer:
2
Explanation:
DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin
Answer:
DNA is tightly coiled into chromosomes

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