Which statement is true? Bronchitis can result in hoarseness. Cystic fibrosis is a genetic disorder that causes thick mucus secr
Natalka [10]

<u>Answer</u>:  Cystic fibrosis is a genetic disorder that causes thick mucus secretions.

<u>Explanation</u>:

  • <em>Cystic fibrosis</em> is a genetic disorder caused by mutations in a gene that makes a protein called CFTR (cystic fibrosis transmembrane regulator).
  • The CFTR protein normally functions as a channel for transport of chloride ions in cells responsible for mucus production.
  • A person suffering from cystic fibrosis produces abnormal CFTR protein or no CFTR protein at all.
  • This is the  reason that thick, sticky mucus is produced instead of the thin, watery kind.

Under what conditions might a person with rh- blood develop rh agglutinins
Mamont248 [21]
<span>A person who has rh- blood can develop rh agglutins through;

When people are being given blood transfusion of wrong blood group then the antibodies will react incorrectly with the transfused blood group, then the erythrocytes clump up and stick together which causes them to agglutinate.</span>

A scientist notices that when she adds a small, water-soluble molecule to a dish of cells, the cells turn off transcription of a
Lelechka [254]

Answer:

Enzyme-linked

Explanation:

The cell surface receptors that have intracellular domains associated with enzymes are called enzyme-linked receptors. The added molecule was water-soluble and cannot pass through the membrane to bind to intracellular receptors. Binding of the added molecule to the enzyme-linked receptor led to the activation of associated enzymes to generate the response (down-regulation of expression of the target gene).

Examples of enzyme-linked receptors include tyrosine kinase receptors. Binding of the signaling molecule to these receptors triggers phosphorylation of the intracellular domain which in turn transmits the signal to the cytoplasmic messenger.
