i'm searching for the answers as well...pls help me!
Phenotype variation is slight variations in a phenotype that are caused by the expression of an organism's genes or the influence of environmental factors. A species can have several different phenotypes within it.
different species of plants having very different DNA causes them to be different species of plants.
Because species adapt to different environments and habitats.
Based on the study by Abzhanov et al. (Bmp4 and Morphological Variation of Beaks in Darwin's Finches. Science 2004 ), the differences in beak shape is partly determined by the expression of a signaling factor (Bmp4). Finches that have larger and broader beaks were shown to express Bmp4 earlier in development and at higher levels. Finches with different shaped beaks were able to exploit different food sources and this allowed the many beak shapes to remain present. After hundreds (or thousands) of years, the birds diverged and became different species.
Song and appearance both play a role in keeping different species from mating.
This depends on the species of wood and the moisture content of that piece of wood.
It is a technique used to distinguish between individual of species on the basis of differences in their dna content
An acceptable moisture content runs anywhere from 4 to 18% depending on a variety of factors including the species of wood, where the wood floor is installed geographically, and the time of year. As a result, most wood used for flooring is kiln dried to 6 to 9% moisture content to assist in keeping it from getting so wet it contracts and so dry it shrinks.
the differences is that the zones are the temperature
Adaptations make the species different from other species, and if they are passed down, they will make more species with these differences.
They are from different species.
Moisture Content, Product Grade, Species or Species Grouping, ALSC-Accredited Supervisory Agency, and Unique Mill Number ID or Mill Name.
That depends on the species. In some there are no visible differences, in others the males and females may look like different species and in still others the differences could be in a colour or fin shape.

They are a totally different species. There is no connection between them apart from the fact that they are both insects.
Their genes might mutate in different directions, so once their genes do not match up, a new species will be made.
