Explanation:
These sugars are transported across the plant by the phloem, a mechanism known as translocation. Sinks are sugar distribution points such as roots, young shoots, and developing plants. The product of photosynthesis is transported from source of production to the storage organs through Phloem
Anna's dog's weight falling outside the average range doesn't necessarily indicate the source is unreliable as it could be affected by individual variability. A broader sample would need to be assessed. Fur color, unrelated to weight, is determined by genotypes.
Anna's female Labrador Retriever being 38 kg (or 83 lb) falls outside the average weight reported in the encyclopedia for female Labradors, which is 25-32 kg (or 55-70 lb). However, these weights are averages and there can be exceptions due to factors such as individual genetics, diet and physical activity level. But, if a large number of Labrador Retrievers greatly exceed or fall below these averages, then it could indicate a problem with the reliability of the source. It's also important to cross-verify such information with other reliable sources. Meanwhile, the fur color is not associated with the weight, but based on alleles. For example, the ee_ genotype makes a Labrador yellow and B_E_ genotype turns it black.
