Answer:
B) DNA and RNA both carry genetic information that encoded for proteins.
D
If it’s recessive you must have both genes of it to carry the actual disease
A doesn’t have it whatsoever so we can eliminate that
C is the genes of a man (has a Y chromosome) eliminate that
B has both recessive so the disease would be present and show eliminate that
Answer:
Hydrogen bonds provide higher surface tension to a liquid. If you disrupt hydrogen bonds, surface tension will decrease. That's why at high temperature, surface tension is lower due to disruption of hydrogen bonds. Hydrogen bonds can be disrupted by the addition of surfactants and surface tension can be reduced also. Detergent is a surfactant because it interferes with the attractive forces between the water molecules.
nutrient that we consume have chemical energy stored within their chemical bond. This nutrient molecules are our main source of energy for metabolism.
chemical energy is potential of chemical substances to undergo transformation through a chemical reaction to transform other chemical substance. food energy is released during digestion whereby molecules in our food are broken into smaller pieces.As bond between these atom loses a chemical reaction occurs.
