Answer:
Since both plants are true breeding, it means that both are homozygous for the allele of the trait, that is flower color. The geranium plant with red flowers can be denoted as RR and the plant with white flowers can be denoted by WW. Since it is not mentioned in the question that which trait is dominant over the other, but one thing is sure that all the offspring will look alike in color, because their genotype will be same, RW.

Answer:
Serovars
Explanation:
Serovars refer to the different strains of a species of microbe that differ from each other with respect to the antigenic composition of a specific structure such as polysaccharides of the cell wall. Serovars are identified suing appropriate antiserum.
For example, the bacterial species <em>Streptococcus pneumoniae</em> have as many as 90 serovars that differ from each other with respect to antigens present in their capsules. These different serovars are identified by using antiserum for specific capsular types which in turn would induce capsular swelling.
Gravity, wind, ballistic, water, and by animals.
The Permian period, which ended in the largest mass extinction the Earth has ever known, began about 299 million years ago. The emerging supercontinent of Pangaea presented severe extremes of climate and environment due to its vast size. The south was cold and arid, with much of the region frozen under ice caps. Northern areas suffered increasingly from intense heat and great seasonal fluctuations between wet and dry conditions. The lush swamp forests of the Carboniferous were gradually replaced by conifers, seed ferns, and other drought-resistant plants.
Early reptiles were well placed to capitalize on the new environment. Shielded by their thicker, moisture-retaining skins, they moved in where amphibians had previously held sway. Over time, they became ideally suited to the desert-type habitats in which they thrive today.
