Petals Around the Rose on the 2, 4, or 6 faces, so these count as zero. There are no petals on the 1 face, so it also counts as zero. There are two petals and four petals on the 3 and 5 faces, respectively. Thus, the solution to a given throw can be found by In the example above, there is one 3 and one 5 face, so the result is two plus four, or six. Petals Around the Rose Petals Around the Rose is a mathematical challenging puzzle in which the object is to work out the formula by which a number is
Plant defense against herbivory reproduction. Many models have been proposed to explore how and why some plants make this investment in defenses against herbivores. The optimal defense hypothesis attempts to explain how the kinds of defenses a particular plant might use reflect the threats each individual plant faces. This model considers three main factors, namely: risk of attack, value of the plant part, and the cost of defense. The first factor determining optimal defense is risk: how likely is it that a plant or certain plant parts will be attacked? This is also related to the "plant apparency hypothesis", which states that a plant
