Unbeknownst to her or her care team, a 51-year-old woman’s breast cancer has an etiology rooted in the fact that tumor suppressing genes are present but have been silenced. Consequently, she has not synthesized normal cancer-suppressing proteins and neoplasia has resulted. What process has accounted for the woman’s cancer?

Unbeknownst to her or her care team, a 51-year-old woman's breast cancer has an etiology rooted in the fact that tumor suppressor genes are present but have been silenced. Consequently, she has not synthesized normal cancer-suppressing proteins and neoplasia has resulted. What process has accounted for the woman's cancer?

A. Chromosomal translocation

B. The “two-hit” hypothesis of carcinogenesis

C. Epigenetic mechanisms

D. A DNA repair defect

Answer: C. Epigenetic mechanisms

Explanation:

In cancer epigenetics the modification of the DNA of the cancer cells occur which will not cause the change in the nucleotide sequence rather it will affect the way, through which the genetic code is being expressed in the body. In cancer different type of epigenetic mechanisms can result which may cause silencing of the tumor suppressor genes, modification of the histone, dysregulation of proteins of DNA, alteration of the methylation pattern of DNA.

According to the given situation, is an example of the epigenetic mechanism of cancer. This is because the tumor suppressor genes of cancer cells are present but these are silenced, that is they are non-functional as a result of this the cancer-suppressing proteins will not be synthesized in the body. This entire condition will be contributing to the neoplasia.

What substance couples electrical excitation to muscle contraction?

Answers

Answer:

Calcium ions.

Explanation:

Calcium ions is stored in the sarcoplasmic reticulum of the muscle fibers. Calcium plays an important role in the muscle contraction.

Smooth muscles use calcium for the phosphorylation of myosin that couples the electrical excitation and initiates muscle contraction. The process of cross bridge cycle occurs in the muscle contraction.

Thus, the answer is calcium.

to control occasional pain and inflammation, a person uses an over-the-counter drug containing ibuprofen. interestingly, recent research shows that the person also may be reducing the risk of contracting which disease?

Answers

Recent research has shown that using over-the-counter drugs containing ibuprofen can potentially reduce the risk of developing certain types of cancer.

Specifically, studies have suggested that regular use of non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen may lower the risk of developing colon, breast, and prostate cancers. This is because NSAIDs work by blocking an enzyme called cyclooxygenase (COX), which is involved in inflammation and also plays a role in the development of certain cancers.

By inhibiting COX, NSAIDs may help prevent the growth and spread of cancer cells. However, it is important to note that regular use of NSAIDs can also have side effects and risks, such as gastrointestinal bleeding and kidney damage.

Therefore, it is important for individuals to consult with their healthcare provider before using NSAIDs for long periods of time or on a regular basis. Therefore ibuprofen can reduce the risk of the disease cancer.

Paulo is an engineer who is hired to design and build equipment for a neuroscience lab that would like to directly record the action potentials of individual neurons. His initial proposal allows for the detection of multiple simultaneous action potentials from the same neuron. A second engineer, Erica, who is reviewing his plans tells him, "You don't need to worry about that. It can't happen." Is Erica's statement true or false?

Answers

Yes, however, there is a limit to how much energy can be stored in a single axon. The precise energy spectrum that each axon may hold is not supported by any actual data. Additionally, it would demonstrate which action potentials an axon can hold or propagate.

What is action potentials?

Action potentials, nerve impulses, or occasionally just spikes are the names given to these spike-like occurrences.

The fundamental events that nerve cells use to convey information from one location to another are called action potentials.

The rapid depolarization (upstroke) and subsequent repolarization of the membrane potential that occurs in excitable cells like neuron and muscle.

The fundamental mechanism for information transmission in the nervous system and in all classes of muscles is called an action potential.

Therefore, Erica's statement true, You don't need to worry about that.
