Which of the following statements is correct in relation to the endocrine system.

Non-nutrient chemicals produced by the body in trace amount that act as intercellular messenger are known as hormones.

Releasing and inhibitory hormones are produced by the pituitary gland.

Adenohypophysis is under direct neu- ral regulation of the hypothalamus.

The correct Answer is:

Which of the following statement is correct in relation to the endocrine system ?

Organs in the body like gastrointestinal tract, heart, kidney and liver do not produce any hormones

Non-nutrient chemicals produced by the body in trace amount that act as intercellular messenger are known as hormones

Releasing and inhibitory hormones are produced by the pituitary gland

Adenohypophysis is under direct neural regulation of the hypothalamus

3-s-orbitl is lower in enrgy thabn 3p-orbital

3-s-orbitl is higher in enrgy thabn 3p-orbital

3s-orbitla is lower in erngy than 3d-orbital

3s, 3p and 3d-orbitlas all have the same enrgy .

Electron`-` electron interaction in the outer orbitals of the elements increases the ionization enthalpy.

Removal of electron from orbitals bearing higher `'n'` value is easier than from orbitals having lower `'n'` value.

The ionization enthalpies of iso`-` electronic species, `F^(-)`, Ne and `Na^(+)` are same because their size and electron configuration are same.

End of valence electrons is indicated by a small jump in ionization enthalpy.
