Though no one has been able to prove a single cause of the Colony Collapse‚ scientists have made some strong theories. 6) Affecting humans The bees are very important to our daily life‚ as they do so much for us. Bee pollination is responsible for more than $15 billion in crop value each year. Besides economically‚ the bees also influence what we eat. One third of all the food that we

’Genetically modified Products: Harmful or Helpful? Genetic‚ modification in products is not a new concept‚ for many years‚ scientist have been doing research in this field‚ consequently there have been a lot of discussion on whether genetic modification of a product is bad or good. Genetic modification was limited to mixing traits of organisms only within the same family of species‚ but due to advanced biotechnology‚ scientist can now genetically modify different species. Genetically engineered

trees. Within the grown farms‚ however‚ the crop is supported along with powerful trellis. The vine bears tiny white color monoecious (male and female) flowers. Generally‚ pollination is completed by honeybees (Apis mellifera). Chayote pears will certainly mature and prepared for harvest right after about Thirty days of pollination. Every plant may possibly yield as much as 150 fruits in the season. The fruit features thin‚ pale green color skin and many short vertical furrows on the surface. Specific

flower density was calculated by dividing the total number of flowers in each pot by the number of plants in their respective pot. Pollination was preformed with a cotton-tipped applicator stick within each treatment separately. Note that pollination was only performed within each treatment‚ take care not to cross-pollinate between low and high-density treatments. Pollination was continued into week five.

How would you feel if I told you that the food you’re eating was made in a science lab? Genetically modified organisms‚ or GMOs‚ are the outcome of a laboratory process where genes from the DNA of one species are extracted and artificially manipulated into the genes of an uncorrelated plant or animal. Crops are often genetically modified to be resistant to pesticides so farmers would be able to spray them without harming the crop itself. However‚ there are many consequences regarding consumers’

Evidence for the rearrangement of crustal plates and continental drift indicates that Australia was once part of an ancient super continent 1.1 Identify and describe evidence that supports the assertion that Australia was once part of a landmass called Gondwana‚ including: - matching continental margins - position of mid-ocean ridges - spreading zones between continental plates - fossils in common on Gondwanan continents including

The U.S. Department of Agriculture estimates that bees contribute to the pollination of about 80% of the country’s insect crops‚ which equates to about $20 billion of produce each year. Avocados‚ apples‚ almonds‚ cucumbers‚ melons and endless additional foods can be accredited to the pollination done by bees. Needless to say‚ their significance spans even farther beyond creating the necessary human food supply‚ as well as to the growth

after two or three flowers had opened‚ a bee stick was used to transfer pollen from one plant to another. Each group then used the bee stick again 2 and 4 days after the initial pollination. Once all of the transferring was complete‚ each unopened bud on the plants were pinched off. Approximately 21 days after pollination‚ the seeds were ready to be harvested. Each quad was removed from the watering tray and allowed to dry for 5 days. After the plants were dry‚ each group removed the dry seedpods
