Carotenoid pigment is a pigment ranging in color from yellow to red; helpful in capturing the Sun's light energy for use in photosynthesis
Answer:
A
Explanation:
1. The colour is non metallic.
2. properties of metal solidness is not there, because of results of hammer experiment.
3. Physical consistency is not solid.
Etc.
Water (H2O) is a fundamental molecule for all living systems. The H2O molecules are capable of absorbing, storing, and releasing energy.
- Water molecules are also capable of expanding upon freezing, dissolving and transporting materials.
- Water reduces the viscosity and the melting temperature of both organic and inorganic compounds (e.g., rocks).
- Water's polarity is responsible for most of its properties.
- Water is a polar molecule because it has one oxygen (O) atom with a slightly negative charge and two hydrogen (H) atoms with a slightly positive charge.
- In consequence, H2O can also be dissolved in other polar solvents.
- For example, alcohols and carboxylic acids are compounds soluble in water due to the presence of a polar hydroxy or hydroxyl (-OH) group.
- The most important water properties include polarity, cohesion, adhesion, specific heat, evaporative cooling, and surface tension.
- Cohesion refers to the fact that hydrogen bonding holds H2O molecules linked together, whereas adhesion is because hydrogen bonding also holds water molecules with other molecules.
- The cohesion of H2O molecules is capable of creating surface tension.
- Specific heat refers to the amount of energy (in Joules) needed to raise the temperature of H2O molecules by one degree Celsius.
- Water molecules have high specific heat, thereby enabling evaporative cooling to occur.
