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

What is Life Life is defined as a characteristic that distinguishes that have signaling and self sustaining processes from those that don’t. If an organism can perform certain functions such as movement‚ respiration‚ sensitivity‚ growth‚ reproduction‚ excretion‚ and nutrition‚ it is classified as a living organism. Life began from the basic building block of all living things‚ called cells. All organisms derived from single celled organisms. Cells are the basic building blocks of life and are

and the egg is fertilized with a meat-bearing seed. The pollen/sperm can belong to the original plant or may come from another sunflower. Self-pollination is a mechanism that the sunflower uses to stay alive. On the occasion where the stigma receives no pollen‚ the stigma will twist and wrap itself around its own pollen. Seeds created by self-pollination will only produce flowers that look like the original plant‚ so no hybridization will have occurred.Sunflowers are fast reproducers‚ and one plant

Nothing! I just wanted to go to the Heavy Mushrooms concert with my friends‚ but no worries it’s too late now. Why can’t you go. I grounded. Well why are you grounded. I snuck out of the house‚ and I wasn’t aloud out. Well there’s nothing I can help you with if it’s too late. So Charlie grabs his can and floats away.

Abstract The plant Brassica rapa is a fast plant most commonly known as the field mustard. The plant itself particularly well known for its extremely fast rate of growth‚ making it easy to breed and cross pollinate several generations. Due to its ability of rapid growth it has become a favorite for scientist to test the theories of inheritance on. In our case we tested to see if we could affect the overall hairiness of different generations. F1 seed was ordered‚ germinated and cross-pollinated
