DNA sometimes has chemical groups attached, called methyl groups, that affect gene expression. Suppose that, during each hour, f

irst a fraction m of unmethylated locations on the DNA become methylated, and then a fraction u of methylated locations become unmethylated. Find a recursion for the fraction f of the DNA molecule that is methylated.

Answer:

f = m - u

Explanation:

DNA methylation is an important epigenetic modification associated with the regulation of gene expression. As such, the analysis of DNA methylation marks and the dynamics of this process may shed light on the genes that are being expressed at a given time in a given cell type/tissue. In the example above described, f is defined as the fraction of the DNA molecule that is methylated after one (1) hour, whose value can be estimated by subtracting u fraction (i.e., fraction of methylated locations that become unmethylated) from m fraction (i.e., fraction of unmethylated locations that become methylated).

In consequence, the equation is

f = m - u

Kyle is holding a bag of 250 jelly beans. When Mark takes out two jelly beans, Kyle is not able to tell a difference.
Fudgin [204]

Answer:

Sensory adaptation.

Explanation:

Hello.

In this case, after the removal of the two jelly beans, Kyle has now 248 jelly beans which is a slightly neglectable difference, it means that the answer is sensory adaptation since it refers to a decrease in the sensitivity to a stimulus due to the constant exposure to it, which also reduces our awareness when a neglectable change happens.

This is proved since Kyle was constantly holding the bag so a difference of two jelly beans will be almost neglectable making the sensory adaptation the reason behind this.

Regards.

When you listen to your favorite music, what is the order in which the sound approaches and enters your nervous system and is in
kvasek [131]
In the ear, the sound waves enter through the auditory canal and hit the eardrum (tympanic membrane). The eardrum amplifies the sound and the waves move on to the middle ear, where three bones called the ossicles (malleus, incus, and stapes) amplify the sound further and vibrate. Then, the sound waves go to the cochlea where tiny hairs and other receptors turn the sound waves into a nerve impulse. This impulse is sent to the brain via the auditory nerve and interpreted by the brain.

I am The red blood cell
Yuliya22 [10]

Red blood cells, also known as RBCs, red cells, red blood corpuscles, haematids, erythroid cells or erythrocytes, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen to the body tissues—via blood flow through the circulatory system. RBCs take up oxygen in the lungs, or gills of fish, and release it into tissues while squeezing through the body's capillaries.

this is about red blood cells but what are you asking
