Reasoning series test

Assertion: In series L-R circuit voltage leads the current. Reason: In series L-C circuit leads the voltage.

Assertion: In any transition series the magnetic moment of M^(2+) ions first decreases Reason: In a transition series, the number of unpaired electrons first increases and then decreases.

Power factor in series LCR circuit at reasonance is

Assertion: Lyman series lies in the visible region of electromagnetic spectrum. Reason: This is because Balmer series also lies in visible region.

Assertion :- Testes originate in the abdomen but but later descend into the secrtum under the influence of testoserone Reason :- The interstitial (Leydig's) cells of the testes sevrete male sex hormone , the testoserone .

Assertion :- Failure of testes to descend into the scrotum sterility in man. Reason:- Higher termperature in the abdomen than in the scrotum is not suitable for sperm devlopment .

Assertion: Transgenic animlas has been used for chemical or toxicity/safety testing Reason: The procedure of chemical safety testing is the same as that used for testing toxicity of drugs
