Explanation

The lipid molecules give fluidity and elasticity to the membrane and membrane protein gives semi-permeability to the membrane

The plasma membrane is also selectively or differentially permeable.

It allows free transport of solvent, i.e., water across it but will not allow free transport of solute particles.

Explanation

Acetic acid can be prepared by the hydrolysis of: Methyl cyanide
(Methyl cyanide, also known as acetonitrile, upon hydrolysis yields acetic acid.)

Explanation

The decomposition reaction is: 

ZnCO 3(s)→ZnO(s)+CO 2(g) One mole of ZnCO₃ produces one mole of CO₂, so 10 moles will produce 10 moles of CO₂.

The molar mass of CO₂ is: 

CO₂=12+(16×2)=44g/mol Therefore, 

10 moles of CO₂=10×44=440g.

Explanation

Gonorrhoea is a sexually transmitted infection, whereas influenza, tuberculosis, and typhoid are spread through other means.

Explanation

The enzymes required for the replication of the HIV, such as reverse transcriptase, integrase, and protease, are located inside the capsid.

The capsid is the protein shell surrounding the viral RNA and enzymes, enabling the virus to replicate once it enters a host cell.

Explanation

Mucus cells in the gastric glands secrete mucin, which forms mucus to protect the stomach lining.

Explanation

For most metals, the temperature coefficient of resistance is positive, meaning that as the temperature increases, the resistance of the metal also increases.

This behavior occurs because, at higher temperatures, the metal atoms vibrate more, leading to more collisions with the electrons flowing through the material, which increases resistance.

Thus, the temperature coefficient of resistance for metals is positive.

Explanation

Sugarcane primarily contains sucrose, which is a disaccharide made up of glucose and fructose.

It is the main sugar extracted from sugarcane.
