Scapula is a flat triangular bone situated in the dorsal part of thorax between

Options:
A first and fifth ribs
B second and seventh ribs
C third and seventh ribs
D second and sixth ribs

The correct answer is:
second and seventh ribs

Solution:

The axial skeleton consists of those bones that are seen in the axis of the body. The appendicular skeleton consists of the bones of girdles and limbs. The pectoral girdle is the upper girdle and it consists of four bones These include two clavicles and two scapulas. The clavicle is the collar bone. It is the only horizontal bone present in the body. It articulates medially with sternum and distally with acromion process of scapula. The scapula is the shoulder blade and is present on the back. This is a flat triangular bone that extends from second to seventh ribs. This consists of a glenoid cavity which articulates with head of the humerus to form the shoulder joint.

Schizocoelomates and enterocoelomates are

Options:
A Acoelomates
B Invertebrates
C True coelomates
D Echinoderms only

The correct answer is:
True coelomates

Solution:
The presence or absence of coelom is an important basis of classifications in animals. Coelom refers to a large fluid-filled space lying between two outer body wall and inner digestive tube.
Schizocoelom arises from a mesodermal split. This body cavity is formed from blocks of mesoderm around the gut that enlarge and hollow out. Example- animals belonging to the Phyla Annelida, Mollusca and Arthropoda. Enterocoelom arises from out pocketing of the embryonic gut (endoderm). This type of body cavity is formed by out pocketing of the primitive gut that breaks off and forms the coelom. Example- animals belonging to the Phyla Echinodermata and Chordata.

Second check point of cell cycle lies between

Options:
A G1 and S phase
B S and G2 phase
C G2 and M phase
D M and G1 phase

The correct answer is:
G2 and M phase

Solution:
Checkpoints are internal controlling mechanisms in the cell cycle. Due to these checkpoints, the cell cycle is monitored at various stages. There are three major checkpoints seen. The first is as the G1 phase ends. Second is when G2 ends and the cell is about to enter the Mitotic phase. The third is during the metaphase.
The first checkpoint checks whether the conditions are suitable for cell division to place or not. If the conditions are not proper the cell will be arrested and will enter the G0 phase instead of the G2 phase. The second checkpoint is at G2-M interphase. Before the cell enters the M phase the cell is checked at this point. This ensures whether all the chromosomes in the cell are duplicated or not. It also checks that the DNA which is replicated is not damaged. The third checkpoint is at the end of Metaphase and this is also known as spindle checkpoint as it checks whether all the chromatids are connected to spindle fibres or not.

Seed dormancy is due to:

Options:
A ethylene
B abscisic acid
C IAA
D starch

The correct answer is:
abscisic acid

Solution:
Abscisic acid induces dormancy of buds towards the approach of winter. Abscisic acid accumulates in many seeds during maturation and apparently contributes to seed dormancy. Because ABA triggers dormancy, this hormone is also known as dormin. The buds and seeds sprout only when the effect of ABA is overcome by gibberellins.
Related Theory
$A B A$ acts as a general inducer of senescence. The onset of senescence is correlated with stomatal closure and destruction of chlorophyll. This hormone inhibits the protein and RNA synthesis. The ABA content of aging leaves increases markedly as senescence is initiated.

Segregation of Mendelian factor (Aa) occurs during

Options:
A diplotene
B anaphase I
C zygotene/pachytene
D anaphase II

The correct answer is:
anaphase I

Solution:
Segregation of Mendelian factor (Aa) occurs during Anaphase I. The paired homologous chromosomes separate during anaphase I in meiosis I so that each gamete receives only one chromosomes of each homologous pair. This disjunction of chromosomal pair leads to segregation of Mendelian factors present on them.
