Chyle is a semi -fluid of partly digested food present in the ileum.

Blood group in man is an example for multiple alleles.

Absorption of glycerol, fatty acids and monoglycerides takes place by lymph vessels (lacteal) within villi.

Cardiac output per minute during normal working in man is about 5 litres.

The failure of descent of testis in scrotal sacs is called cryptorchidism.

Principle of of segregation is the universally applicable principle of Mendel.

In the human brain, corpora quadrigemina represents the midbrain.

The deficiency of vasopressin causes diabetes insipidus.

Unipolar nerve cells are found in vertebrate's embryo.

The organ of corti is found in cochlea.

A multinucleate condition in animals is referred to as syncytium.

Hashimoto's disease is a disorder in which antibody destroys the thyroid.

The longest phase in prophase I of meiosis is  pachytene.

Myosin protein is found in dark band.

The number of cells formed from one cell at the end of Meiosis II are 4.

The enzyme involved in crossing over is recombinase.

The transition stage of meiotic prophase I to metaphase I is diakinesis.

The cell cycle consists of a mitotic (M) phase, during which first nuclear division (mitosis) and then cell division (cytokinesis) take place. The shortest phase in the cell cycle is M phase

Spindle fibres are made up of tubulin.

The cell cycle consists of a mitotic(M) phase, during which first nuclear division (mitosis) and then celldivision (cytokinesis) take place. The M phase is followed by a long period of growth known as interphase. Interphase has three subphases (G1, S and G2) in cells that divide.

In cell cycle process, the term generation time is used to refer the time required for the completion of cell cycle.

The type of cell division occuring during the maturation phase of spermatogenesis is meiosis in which half the chromosomes of the parent cells are formed.

The homologous chromosomes pair by adhering along their lengths, a process called synapsis. This process occurs in zygotene.

Size of the ribosomes is indirectly indicated by 'S' which stands for sedimentation coefficient.

The most active phase of nucleus during cell division is interphase, in which all the metabolic activities like chromosome and centriole duplication, DNA replication, cell growth etc. take place.
