Answer:
I think it is C, the remnants of leg bones of a whale
Answer:
Part of this pollen travels down the style and then into the ovary. The tiny piece of pollen joins onto an ovule in the ovary. The plant has now been fertilised. The ovary of the flower turns into seeds which will then be dispersed so that new plants will be able to grow somewhere else.
The Gulf Stream is a very strong current pressed up against the east coast of the United States. It brings warm water from the Gulf of Mexico into the North Atlantic, and it’s driven by the winds over the Atlantic. It carries a lot of water: about 80 million cubic meters of water per second near Cape Hatteras in North Carolina. A cubic meter is about the amount of water in a bathtub, so there’s about 80 million bathtubs of water per second flowing through that section.
After leaving Cape Hatteras, the Gulf Stream crosses the Atlantic Ocean, with some of its waters turning south in the eastern Atlantic, and some turning towards the north. The latter branch serves as a major heat source for the weather and climate of Western Europe. Great Britain and Scandinavia would be a lot colder if it weren’t for the Gulf Stream.
It affects weather in the U.S., too. By bringing so much warm water along the mid-Atlantic and southeastern states, it adds some warmth to the eastern coast of the U.S. The Gulf Stream also affects the paths of hurricanes, and their strength — they intensify as they draw up the heat from the warm water. So factoring in the Gulf Stream is essential in predicting hurricanes heading toward the U.S.

Abstract
Down syndrome (DS) is associated with aberrations in genetic, morphological, biochemical and physiological characteristics. A number of genes located on human chromosome 21 (HSA21) encode proteins which are thought to be involved in numerous metabolic pathways, e.g., phosphofructokinase, cystathionine β-synthase etc. Perturbations of the metabolic pathways may lead to altered drug metabolism in DS individuals. We present a review of metabolic aberrations linked to HSA21 genes in DS. We particularly focus on drug disposition, efficacy, sensitivity and toxicity of anti-leukaemic agents including methotrexate, glucocorticoids, anthracyclines and cytarabine in DS leukaemia. The different outcomes of therapy due to differential drug response, varied drug toxicity and treatment related mortality in DS leukaemia is a subject of much research and speculation. Altered drug response in DS individuals may stem from differences in pharmacokinetics, pharmacodynamics and pharmacogenetics. Further large-cohort studies in different age groups dissecting metabolic and molecular pathways involved in drug response may increase our understanding in this regard and stipulate pharmacotherapies in DS.
Answer:
Urbanization also affects the broader regional environments. Regions downwind from large industrial complexes also see increases in the amount of precipitation, air pollution, and the number of days with thunderstorms. Urban areas affect not only the weather patterns, but also the runoff patterns for water.
