All of the above are protozoan related infections.

These bones are in the form of nodules inserted in tendons and joint capsules. The most common examples are patella, pisiform and fabella.

Alcalase is a protease enzyme commonly added to laundry detergents to break down protein-based stains such as blood, grass, and food. Other enzymes like xylanases, peroxidases, and catalases serve different industrial or biochemical functions.

Yes, it is correct. It is the scientific name of cockroach.

 The term new systematics was introduced by Huxely. In new systematics the species are considered related to one and another, mutable and show gradual modification.

The four life stages of mosquito: embryo, larva, pupa and imago.

Chitin forms the exoskeleton in arthropods including Periplaneta (cockroaches). Ascaris and Pheretima are annelids (worms) that lack chitinous exoskeletons. Hydra is a cnidarian and amoeba is a protozoan - neither has a chitin exoskeleton. Chitin provides structural support and protection in arthropods.

Hirudin is the specific anticoagulant produced by medicinal leeches (Hirudo medicinalis) to prevent blood clotting while they feed. Heparin is produced by mast cells and basophils in mammals, not leeches. Sodium citrate is an artificial anticoagulant used in laboratory settings, not a natural leech product.

No crossing over can take place between them.

Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones. Hence, the hormone is related with growth.

During its life cycle, the silkworm actively spins continuous silk filaments to form its protective cocoon while it is in the caterpillar or larval stage.

Sickle cell anaemia is a genetic disorder caused due to fault in haemoglobin protein expression.

Insects belong to the phylum Arthopoda.

Erythrocytes is the scientific name for red blood cells (RBCs), derived from Greek 'erythros' (red) and 'kytos' (cell). Leucocytes are white blood cells, thrombocytes are platelets, and plasma is the liquid portion of blood. RBCs contain hemoglobin and transport oxygen throughout the body.

Eugenics is the set of beliefs and practices which aims at improving the genetic quality of the human population.
