Angiosperms are plants that have stems, roots and leaves. Moreover, these plants have seeds in a flower. Usually, angiosperm eggs are fertilized through pollination in a flower. Flowers have both male and female reproductive organs. Based on the analysis of the nucleotide sequences of genes, it appears that the ancestors of angiosperms were adapted for survival in shady forests.
Answer:
C) polarity
Explanation:
The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.
- In water molecules hydrogen bonds provides a special dipole - dipole attraction.
- Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine).
- This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge.
- This makes the molecule of water polar.
- By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.
This property of water is polarity of water.
The dry cleaning industry is the primary user of the chemical perchloroethylene (PCE). The research done by the researchers at the Boston university have found that the PCE chemical increases the risk of developing mental illnesses in the people working with it. Since, it is a common name in the dry-cleaning industry, the workers in this industry are much more prone to mental illnesses a compared to other people.
Hence, the answer is 'dry cleaning industry'.
