Answer to Problem 1CR

The liquid flower nectar collected by honeybees can be used for humans. Also, they help in the process of pollination. Pollination is the transfer of pollen within and among flowering plants. The factors that lead to this decline of honeybee population include pesticide exposure, attacks of parasitic mites, invasion of African honeybees, a virus traced to Israel, a particular type of fungus, and poor nutrition. A phenomenon that occurs when all the bees abandon a colony is termed as colony collapse disorder.

Explanation of Solution

The insect pollinated plants constitute about one-third of the U.S food supply. The major type of insect that is responsible for 80% of that pollination is honeybees. Industrious honeybees flit from one flowering plant to another in meadows, forests, farm fields, and gardens existed around the world. They collect the liquid flower nectar to take back to their hives. They also collect pollen grains that stick to the hairs on their legs. The pollen rich in protein is fed to young honeybees and the honey made from the collected nectar and stored in the hive is fed to the adults.

They provide one of the most important ecosystem services of nature. It involves the transmission of pollen stuck on their male bodies to female reproductive organs of either the same flower or different flower. This fertilization allows the flower to form fruits and seeds.

Pollination can be defined as the transfer of pollen within and among flowering plants. It allows them to produce seeds and fruit.

Since 1980s, the population of honeybee in the U.S has declined at a rate of 30 to 40%. The factors that lead to this decline include pesticide exposure, attacks of parasitic mites, invasion of African honeybees, a virus traced to Israel, a particular type of fungus, and the poor nutrition results due to the drop in the natural diversity of flowers and other plants on which the honeybees feed.

Colony collapse disorder can be defined as a phenomenon that occurs when all the bees abandon a colony. Since 1980s, the number of European honeybees was reducing. However, a massive decline in the number of bees occurred due to the disappearance of bees from their colonies in the United States and some areas of Europe since 2006.

Radioactivity has provided a reliable means for calculating the numerical (absolute) age of rocks, a procedure called radiometric dating. Radioactive isotopes, such as uranium-238, emit particles from their nuclei that we call radiation. Ultimately, the process of decay…
