- Hepaticopsida (Liverworts)
- Anthocerotopsida (Hornworts)
- Bryopsida (Mosses)

Liverworts come under this class.
Hepaticopsida is further divided into 4 orders:
- Marchantiales (e.g. Riccia, Marchantia)
- Sphaerocarpales (e.g. Sphaerocarpos)
- Calobryales (e.g. Calobryum)
- Jungermanniales (e.g. Pellia)
- species
- order
- family
- genus

- structural
- transport
- contractile
- regulatory
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Hemoglobin is an example of a transport protein.
Transport proteins are a class of proteins that facilitate the movement of molecules, and ions, within cells.
It is a transport protein found in red blood cells
They are responsible for transporting oxygen (O2) from the lungs to tissues throughout the body
And for transporting carbon dioxide (CO2) from tissues back to the lungs for exhalation.
- May be at same locus
- May not be at the same locus
- At the same locus
- At different locus
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Alleles of a gene are located at the same locus on homologous chromosomes.
A locus refers to a specific location or position on a chromosome where a particular gene is located.
- gall stones
- pyrosis
- anaema
- jaundice
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Gallstones, mainly cholesterol gallstone formation, result from several physiological events such as:
- hepatic secretion of bile saturated with cholesterol
- nucleation of cholesterol monohydrate crystals in the gall bladder
- impaired emptying of gall bladder contents.
