A hemopheliac is someone with a bleeding disorder resulting from any missing clotting factors in their blood. Vasoconstriction isn't generally the problem in hemophiliacs, nor is it the destruction of pathogens. If fibrin threads are not present to help form the platelet plug, then excessive bleeding occurs. Fibrin is one clotting factor that a hemophiliac may be missing which is then causing the disorder.
<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.
Marginocephalia, ceratopsians - like the triceratops. These dinosaurs are usually depicted with two horns coming from the top of orbits and one from the top of the nose.

Answer:
The cytosol is best described as semifluid substance in which organelles are suspended.
Explanation:
Cells have different components. They can be divided in eukaryotic and prokaryotic. When it comes to the first type, they have a defined membrane for the nucleus. When it comes to the second ones, they have their nucleus in all the cytosol. <em>The cytosol is the space in the cell made of a semifluid subtance with different organelles suspended</em>.
Just to mention some of the organelles that can be there, we can find mitochondrion
, endoplasmic reticulum
, centriole
, among others.
