Match the following column I with column II.

Column â I	Column â II

A. Metaphase - II	1. Centromere with 2 kinetochores

B. Anaphase - I	2. Disjunction

C. Mitosis	3. Synapse

D. Zygotene	4. Plectonemic coiling

Options:
A ABC124D3
B ABC314D2
C ABC231D4
D ABC413D2

The correct answer is:
ABC124D3

Solution:
The chromosomes become arranged on the metaphase plate, much as the chromosomes do in mitosis, and are attached to the now fully formed spindle. In metaphase II, the centromeres contain two kinetochores that attach to spindle fibers from the centrosomes at opposite poles. The new equatorial metaphase plate is rotated by 90 degrees when compared to meiosis I, perpendicular to the previous plate.
Disjunction of chromosomes takes place in anaphase-I and II when chromosomes move to the opposite poles of the cell.
Plectonemic coiling refers to inter-twining of a double helix DNA molecule in such a way that for its correction unwinding of DNA helix molecule is required, this take place in mitosis in which sister chromatids are tightly coiled upon each other. In the zygotene stage, homologs login to synapse by coming to approximate alignment.

Solution:
When the haemoglobin molecule binds the oxygen molecule, the resultant compound is called Oxyhaemoglobin. When the haemoglobin molecule binds the CO2 molecule, the resultant compound is called Carbamio-haemoglobin.
When Hb binds to CO, it forms an irreversible compound called carboxyhaemoglobin which causes carbon monoxide poisoning.
Methaemoglobin is referred to the Hb molecule which has oxidised iron moieties. In such a molecule, there is a Fe3+ instead of the normal Fe2+.

Solution:
The last 2 pairs (11th and 12th) of ribs are not connected ventrally to the sternum and are, therefore, called floating ribs.

Each half of the pectoral girdle consists of a clavicle and a scapula. The scapula is a large triangular flat bone situated in the dorsal part of the thorax between the second and the seventh ribs. The dorsal, flat, triangular body of the scapula has a slightly elevated ridge called the spine which projects as a flat, expanded process called the acromion which forms the highest point of shoulder. The clavicle articulates with this. Below the acromion is a depression called the glenoid cavity which articulates with the head of the humerus to form the shoulder joint. Each clavicle is a long slender bone with two curvatures. This bone is commonly called the collar bone.
