The mastectomy or the removal of breast lumps can cause Lymphedema.

During the surgery, some of the Lymph nodes in the under arms are also removed. The removal of the lymph nodes compromises the lymphatic system.

The Lymphedema is a condition, in which the fluid retention takes place in the lymph nodes. This condition is mainly caused by the compromised lymphatic system, which occurs due to the removal of lymph nodes during mastectomy or lumpectomy.

weqwewe [10]

Answer:

The answer is D) It will affect the primary, secondary, and tertiary structures of the CFTR protein.

Explanation:

The deletion of phenylalanine (F) in position 508 or F508, <u>disrupts the sequence of amino acids and polypeptides</u>, as seen in the <u>primary structure</u>.

It also affects the <u>secondary structure</u> since it can <u>alter the folding or kinks of the alpha-helices or beta-sheets</u> of the local polypeptide chain.

For the <u>tertiary structures</u>, it will <u>affect the overall shape of the CFTR protein</u>, and ultimately, <u>alter its function in the body</u> which is to produce thin, free-flowing mucus in the respiratory, digestive, and reproductive system, etc.

<h3>What is the CFTR Protein?</h3>

Normally, the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein functions as a <u>membrane channel protein</u> that transports negatively-charged ions, such as <u>chloride ions</u>, in and out of the cell. It also <u>transports water</u> which is used to <u>form thin, free-flowing mucus</u> seen in the <u>respiratory, digestive, and reproductive systems</u>. It can also influence other channels to <u>regulate the entry of sodium ions across plasma membranes</u> seen in the <u>pancreas and lungs</u>.

The CFTR protein mutation found in Cystic Fibrosis (CF) is present in almost <u>70% of CF patients</u>. The mutation <u>alters the structure of the chloride ion channel</u> and movement of chloride ions and water in and out of the cell. Thus, <u>impairing the production of mucus, which is characteristically sticky and thick</u> seen in Cystic Fibrosis.

if you measure the age of a fossil using 14c dating and determined its age to be about 17000 years old, how much of the rock sho
k0ka [10]

Answer:

Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50,000 years, and most rocks of interest are older than that. Carbon dating is used by archeologists to date trees, plants, and animal remains; as well as human artifacts made from wood and leather; because these items are generally younger than 50,000 years. Carbon is found in different forms in the environment – mainly in the stable form of carbon-12 and the unstable form of carbon-14. Over time, carbon-14 decays radioactively and turns into nitrogen. A living organism takes in both carbon-12 and carbon-14 from the environment in the same relative proportion that they existed naturally. Once the organism dies, it stops replenishing its carbon supply, and the total carbon-14 content in the organism slowly disappears. Scientists can determine how long ago an organism died by measuring how much carbon-14 is left relative to the carbon-12.
