Some cells do not have gap phase in their cell cycle whereas some cells spend maximum part of their life in gap phase.

In the life cycle of Bryophyta, gametophyte is the dominant phase whereas in the life cycle of Pteridophyta, sporophyte is the dominant phase.

The relation may be given as : `DeltaG=-nFE_(cell)` If the redox reaction is under standard conditions, then `DeltaG^(@)=-nFE_(cell)^(@)` Here nF is the quantity of charge passed. In case we want...

On applying opposing potential, reaction continues to take palce till the magnitude of opposing e.m.f. reaches the value of 1.1" V". After this , reaction stops and no further reaction...

Correct Answer - D (d) Bacon cell was used in Appolo mission. It is named after the British Scientist who developed it.

Correct Answer - D (d) Average life is more Hence more nuclei decay in one avaerage life .

Correct Answer - C During charging, `E=V+ir` (due to reversed current). In case of charging emf of a cell is less than its terminal voltage while in case of discharging emf...

(b). Flamingo

1. Marine birds like Albatross have special glands called salt glands near their nostrils. 2. These glands are capable of secreting salts by active transport and help to manage osmotic balance,

`Pt,Cl_(2)|Cl^(-)(aq)||Cl^(-)(aq)|Cl_(2)(g),Pt` anode : `2Cl^(-)toCl_(2)+2e^(-)(R.H.S)` cathode: `Cl_(2)+2e^(-)to2Cl^(-)(L.H.S)` `E_(cell)=0-(RT)/(nF)ln([Cl^(-)]_(LHS))/([Cl^(-)]_(RHS))` `E_(cell)=(RT)/(nF)ln([Cl^(-)]_(RHS))/([Cl^(-)]_(LHS))`

Correct Answer - A (a) Sexual phase in the life cycle of Plasmodium occurs in the gut of mosquito. Sexual phase involves the gametocytes, megagametocytes (female) and microgametocytes (male) which reach...
