 Evolution of Angiosperms(flowering  plant) fossil records place the massive appearance  angiosperms in the middle to late Mesozoic era. Angiosperms (“seed in a vessel”) produce a flower containing male and/or female reproductive structures. Fossil evidence indicates that flowering plants first appeared in the Lower Cretaceous, about 125 million years ago, and were rapidly diversifying by the Middle Cretaceous, about 100 million years ago. Earlier traces of angiosperms are scarce. Fossilized pollen recovered from Jurassic geological material has been attributed to angiosperms. A few early Cretaceous rocks show clear imprints of leaves resembling angiosperm leaves. By the mid-Cretaceous, a staggering number of diverse, flowering plants crowd the fossil record. The same geological period is also marked by the appearance of many modern groups of insects, including pollinating insects that played a key role in ecology and the evolution of flowering plant(Taylor 2006).  ...

 How do I set up a rating scale question correctly? If you incorrectly set up a rating scale question, this could confuse your respondents, muddy your data results and waste your time. There are several things to note when setting up your rating scale question: 1. Identify your scale points The scale’s points should map as closely as possible to the underlying idea (construct) of the scale. Also, the scale should give enough points to differentiate respondents from one another as much as validly possible It should be easy to interpret the meaning of each scale point - i.e. the meaning of scale points should be interpreted identically by all respondents. 2. Using the right rating scale The breakdown of each rating scale type above should give you an idea of how you can incorporate these into your survey (see the bolded text for a quick reference). However, if you’re not sure about using one type over another, consider using them both in a test first. If your results show you what yo...
