In human digestive system, the enzyme that digests fats is: MCQ with Answer and Explanation

Explanation:
The man's genotype is Iᴬ Iᴮ (AB) and the woman's genotype is ii (O). Gametes: man produces Iᴬ or Iᴮ, woman produces i only. Offspring: Iᴬ i (blood group A) and Iᴮ i (blood group B). Thus only A and B blood groups are possible. No AB (requires both Iᴬ and Iᴮ) or O (requires ii) children can be produced. This illustrates co-dominance and multiple alleles.

Explanation:
Rickets is a childhood bone disorder caused by a severe deficiency of Vitamin D (Calciferol), or sometimes calcium or phosphate. Vitamin D is essential for the absorption of calcium and phosphorus from the gut. Its deficiency leads to soft, weak bones, resulting in skeletal deformities like bowed legs, delayed growth, and bone pain. Osteomalacia is the adult equivalent.

A virus is an obligate intracellular parasite. The basic structure of a virus particle, or virion, consists of genetic material (either DNA or RNA, but never both) enclosed in a protective protein coat called a capsid, made of subunits called capsomeres. Some viruses also have an outer lipid envelope derived from the host cell membrane.
