Noted scientist Dr. Elsa Birde described the effect of adding a mixture of dried apples and raisins to the previous feed of sunf
lower seeds, millet, thistle seed, and cracked corn in bird feeders in her yard. Over three years, Dr. Birde observed that the new mixture increased the number of songbirds at her feeders, especially during the months of April and May. As she has done for several years, Dr. Birde recorded, at the same time each day, the number of birds at each of her four feeders. She noted that the third year using the mixture coincided with the largest increase. There was a twenty-five percent increase in the number of songbirds over times when this mixture was not used. Dr. Birde also noted that in the third year she used a specific ratio of the ingredients, carefully measuring, which she had not done in previous years. The third year also had a warmer than normal spring, and a construction project began in a neighborhood near Dr. Birde’s. Dr. Birde is now going to produce this formula for sale and advertise to customers that they may see the same twenty-five percent increase in songbirds at their feeders. Dr. E. Birde, Journal of Scientific Bird Feeding Which scientific claim can be made? Songbird numbers will increase due to the effects of climate change increasing global temperatures
The correct option is this: A STUDY BY DR BIRDIE SHOWED THAT THE NUMBER OF SONGBIRDS IN HER YARD INCREASED DUE TO A MODIFIED FOOD SOURCE. A scientific claim refers to a claim that is made by a scientist due to the result that he or she obtained in the research that are conducted. In the excerpt given above, it can be seen that Dr Birdie experience influx of songbirds to her yard as a result of the dried apple and the raising that she added to the birds' food.
Interestingly, some cells in the body, such as muscle cells, contain more than one nucleus ((Figure)), which is known as multinucleated. Other cells, such as mammalian red blood cells (RBCs), do not contain nuclei at all.
A transmembrane protein spans the phospholipid bilayer one or more times. they are made of amphiphilic phospholipids: phospholipids with a hydrophilic phosphate head and a hydrophobic tail with two fatty acid chains.
The type of bonds that are involved in these transient protein - DNA interactions include: IONIC BOND, VANDER WAAL FORCES AND HYDROGEN BOND. Protein - DNA interaction occur when a protein bind to DNA molecule; this reaction usually occur in order to regulate the function of DNA, especially that of expression of genes. Protein interaction with DNA may be specific or non specific.
