Red and yellow bell pepper plant can reproduce with each other - Genetic diversity.
A park has 80 species of trees - species diversity.
There are many breeds of dogs - genetic diversity.
Five different bird species are at a bird feeder - species diversity.
Evolution Due to environmental factors, It may not look it, but, needles are leaves, they collect solar radiation to produce glucose through the process of photosynthesis, however, needles are, some would say, evolutionary superior to leaves. Needles themselves hold in more water due to their dense wax coating, they are very difficult for insects and other organisms to eat, one because of their structure, and two because of their acidity, they can catch sunlight all year long due to their winter resilience( they don't fall, during the winter), and they have less surface area for wind to catch, which leaves them better protected from wind than most deciduous trees, however the surface area can also pose a larger problem for less surface area means less sunlight interception, therefore more are needed to compete against regular leaves. But.. I Digress... Plant needles are 'PROBABLY' initially the result of evolution of narrow leaves due to climate or environmental factors.
Sry its so long got carried away! Hope this helps xD
<span>Avery Identified through a qualitative test that DNA was present. Through a chemical test he found that the make up was DNA. Through enzyme testing Avery found that only DNA degradation stopped transforming.</span>
