Question

In living organisms, a bone skeleton maintains the body shapes. In a cell this shape is maintain by water pressure cytoplasm cytoskeleton exoskeleton Around 90% of the protein structures available in the Protein Data Bank have been determined by X-ray crystallography. This method allows one to measure the three-dimensional (3-D) density distribution of electrons in the protein, Select the typo of bonding that accounts for this three dimensional structure Hydrogen Bonding Van der walls polar covalent bonding ionic bonding Most unsaturated fats are liquid at room temperature and are called oils True False

Explanation / Answer

Ans-61 Cytoskeleton maintains the shape of a cell.

Ans-62

Polar covalent bonding-because x-rays and covalent bonds have similar wavelength, and therefore currently provides the best visualization of protein structure

Ans-63

True- Unsaturated fat contains one or more double bond which are liquid at room temperature. e.g- canola, nuts and olive oils.
