A pairs with T (Thymine)
C Pairs with G (Guanine)
Divergent boundaries in the middle of the ocean contribute to seafloor spreading. As plates made of oceanic crust pull apart, a crack in the ocean floor appears. Magma then oozes up from the mantle to fill in the space between the plates, forming a raised ridge called a mid-ocean ridge.
They should repeat their experiments, use their results to disprove the existing theory, and publish an extensive paper to bring attention to their discoveries.
<span>Lactase persistence, the ability to digest the milk sugar lactose in adulthood, is highly associated with a T allele situated 13,910 bp upstream from the actual lactase gene in Europeans. The frequency of this allele rose rapidly in Europe after transition from hunter–gatherer to agriculturalist lifestyles and the introduction of milkable domestic species from Anatolia some 8000 years ago. Here we first introduce the archaeological and historic background of early farming life in Europe, then summarize what is known of the physiological and genetic mechanisms of lactase persistence. Finally, we compile the evidence for a co-evolutionary process between dairying culture and lactase persistence. We describe the different hypotheses on how this allele spread over Europe and the main evolutionary forces shaping this process. We also summarize three different computer simulation approaches, which offer a means of developing a coherent and integrated understanding of the process of spread of lactase persistence and dairying.</span>
Answer:
Minerals have distinguishing physical properties that in most cases can be used to determine the identity of the mineral.... Among the properties we will discuss are: crystal habit, cleavage, hardness, density, luster, streak, color, tenacity, magnetism, and taste. Crystal Habit. In nature perfect crystals are rare.
