I have seen several people get this wrong a lot. Cilia, which is more associated with cell movement is not so with Paramecium. To capture food, a Paramecium uses its cilia to capture food and transport it to the "mouth"
La biología (del griego «βιος» bios, vida, y «λóγος» logos, razonamiento, estudio, ciencia) es una de las ciencias naturales que tiene como objeto de estudio a los seres vivos y, más específicamente, su origen, su evolución y sus propiedades: génesis, nutrición, morfogénesis, reproducción, patogenia, etc.
1.
Primary Structure : It refers to refers to the sequence of amino acids in the polypeptide chain.
2.
Secondary Structure : Within the long protein chains there are regions in which the chains are organized into regular structures called
Alpha Helix (
- helix ) and
Beta - pleated sheets . Hydrogen bond is present in secondary structure.
3.
Tertiary Structure : The overall three dimensional structure of polypeptide chain is called Tertiary structure.
Hydrogen bonding,
ionic bonding,
dipole-dipole interactions
, Disulfide bonding are present in tertiary structure.
4.
Quaternary Structure : The polypetide chain aggregates and the protein contains more than one amino acid chain. This is Quaternary structure.
Hydrogen bonding is present in them.
Many cases of early onset of Alzheimer’s disease are inherited
Answer:
pharynx, larynx, trachea, bronchi
Explanation:
During the inhalation through the nose or mouth the air first enters the "pharynx" which is also called as throat,
then the air moves towards the "larynx" . Is a passage between the pharynx and the trachea
Through larynx the air then moves toward the "trachea". It is passage connecting the larynx and the bronchi
and then the air inhaled reaches to the "bronchi" of lungs.
hence, the correct order is "pharynx, larynx, trachea, bronchi"
