Answer:

Sexual reproduction in plant waste energy and pollen grains because the size of pollen grains is very small and in sexual reproduction there is less chances of reaching the pollen grains to the stigma of the flower. So that's why more pollen grains will fall on the stigma of the flower in order to fertilize the ovary. For fertilization, few pollen grains are enough if reach on the stigma.

maks197457 [2]
Stable isotopes refers to those isotopes that do not undergo radioactive decay. Oxygen atoms with atomic number of 16 and 18 are examples of stable isotopes. These isotopes of oxygen are usually found in substances such as polar ice and calcite. These substances are usaually measure with isotope fractionation and the ratios obtained are used to estimate water temperature of ancient oceans. From this, scientists can find out facts about ancient climates,

stepladder [879]

Halons and cfc’s both destroy ozone layer in the stratosphere.

  • Chemicals with carbon, chlorine, and fluorine atoms are known as chlorofluorocarbons (CFCs), and they are neither poisonous nor combustible.
  • They are employed as solvents, refrigerants, blowing agents for foams and packaging materials, and in the production of aerosol sprays.
  • Halons, hydrochlorofluorocarbons, and chlorofluorocarbons all damage the ozone layer, which protects the planet from damaging ultraviolet (UV-B) rays from the sun.
  • Additionally warming the earth's lower atmosphere, CFCs and HCFCs alter the climate on a global scale.
  • Life on earth is made possible by the stratospheric ozone layer, which protects the planet from the sun's harmful ultraviolet (UV-B) rays.
  • Ozone in the upper atmosphere is destroyed by man-made substances such halons, hydrofluorocarbons, and chlorofluorocarbons (CFCs)
