Answer:
A new born baby can turn blue when there is not enough oxygen rich blood in his body
Explanation:
TGV - Transposition of the great arteries is a defective heart condition that occurs from birth. The two great arteries are the aorta and pulmonary artery. The aorta carries oxygen-rich blood from the heart to the rest of the body while the pulmonary artery carries oxygen deficient blood from the body to the lungs
Normally the aorta which is supposed to be connected to the left ventricle and supply oxygen rich blood from the heart to the rest of the body is transposed. Meaning that it is instead connected to the right ventricle and carries oxygen-deficient blood to the body.
Conversely in TGV situation, the pulmonary artery is connected to the left ventricle (instead of the right ventricle) and carries oxygen rich (instead of oxygen-deficient) blood to the lungs.
The result is that the new born baby body has oxygen deficient blood and hence begins to burn blue (cyanotic)

Explanation:
He popularised the cell theory
<h2>Answer:</h2>
- Ionic bond: It is the bond formed by the complete transfer of electron from one atom to an other atom.
- Covalent bond: It is the bond formed by the mutual sharing of the electrons.
- Van der waal: These are weak interactions between one molecules with other polar or non polar molecules to hold to each other by weak force of attraction.
<h2>Explanation:</h2>
- <u>Similarities between van der waal, ionic bonds and covalent bonds:</u> All of them are a type of inter-molecular forces, in which ionic bonds are stronger than covalent bond and van der walls forces. And covalent bonds are stronger than van der wall forces.
- <u>Difference between van der waal and ionic bonds:</u> Ionic bonds are formed by complete transfer of electrons from one atom to an other atom. Covalent bond are formed by sharing of electrons while in van der waal, there is a slight attraction when oppositely charged molecules come close to each others.
Result: Van der wall forces are weakest among ionic and covalent bonds.
