Answer:

What keeps intracellular receptors from binding to DNA before a hormone binds to the receptor? chaperone proteins (chaperonins). each receptor has two binding sites. The chaperone protein blocks the DNA binding site until a hormone binds at the hormone binding site.

The ________ duct empties into the vestibule at the level of the second upper molar.

gavmur [86]

The parotid duct empties into the vestibule at the level of the second upper molar.

Around the back of your lower jaw is where the parotid gland is located. Saliva then passes via a tube known as the parotid duct. The duct's opening is where the saliva spills into your mouth. Different factors might cause the parotid duct to become clogged. The region may swell up as a result of this.

Each gland's front faces a lengthy excretory channel called the parotid duct, which emerges just beneath the masseter muscle. The duct enters the mouth by the buccinator muscle and opens on the inner cheek surface, typically next to the maxillary second tooth

select the cell cycle impairments that you predict would lead to cancer. recall that cancer arises from unregulated, repeated ce

Vera_Pavlovna [14]

Cancer cells can arise in a variety of ways, the most common, however, tends to be genetic mutations.

Genetic mutations can occur during the life of a cell due to outside factors such as:

The food we eat
The environment we expose the cell to
The substances that touch the cell (e.g skin cells)

That being said, the most common time for a genetic mutation to take place is during cellular division. During this time the DNA that encodes the cells is duplicated. Genetic mutations in this DNA sometimes cause the elimination of programmed cell death.

Programmed cell death is what tells a cell when it should stop growing and dividing. This is a regulatory function designed to keep the number of cells at a balance, growing only when needed. As this cell multiplies, this produces an increasing number of cells that will not die. The accumulation of these cells is referred to as cancer.
