 #### Impact
 _requireTroveIsActive is a function in TroveManager to check that Troves[_borrower][_collateral].status is active or not. in contract BorrowerOperations and functions _adjustTrove, before making calls to applyPendingRewards, we make the call to function BorrowerOperations._requireTroveisActive to check Trove is Active, then in contract TroveManager and function applyPendingRewards, again we check that Trove is Active by TroveManager._requireTroveIsActive function.
 
-we can remove call to BorrowerOperations._requireTroveisActive in functions _adjustTrove, because in anyway we make call to the TroveManager.applyPendingRewards and in TroveManager.applyPendingRewards we check TroveManager._requireTroveIsActive.

+another Unnecessary duplicate check is _requireValidCollateralAddress in ActivePool.sendCollateral and DefaultPool.pullCollateralFromActivePool. in one transaction, we call _requireValidCollateralAddress twic.
