Bio accumulation of DDT lead to bird eggs with weak shells and non viable offspring. The lethal effects of DDT on birds was first noted in 1950; scientists discovered that earthworm was accumulating the DDT pesticide and that the robins that were preying on the earthworms were been poisoned. Further research revealed that the chemical cause thinning of the egg shell and production of non viable offspring. The chemical has since been banned in USA.
1) carbohydrates cannot be dissolved easily unlike fats as they are insoluble in water.therefore the amount of energy given from carbohydrates lasts longer than fats
2)fats can be accumulated on the coronary artery(the artery which supplies blood to the heart)there lots of intake of fats can result in heart attack
3)carbohydrates are non sticky and from chain of compounds unlike fats.
Large, no polar organic molecules that don’t dissolve in water

Explanation:
Parthenogenesis is a method of asexual reproduction in which an egg cell develops into a new individual without fertilization. Parthenogenesis occurs in insects, amphibians, reptiles, fish, and in some plants. Most of the organisms which reproduces through parthenogenesis, they also reproduce sexually. Parthenogenesis may be occurs by apomixis and by automixis. In apomixis, egg is produced by mitosis and results into diploid clones. In automixis egg is produced by meiosis and the haploid egg develops into diploid new individual by the duplication of chromosomes. Parthenogenesis is an adaptation which allows to reproduce in adverse environmental conditions when sexual reproduction is not possible.
