developmental defects of teeth with recent genetic concepts INTRODUCTION: Disorders of development of teeth may be prenatal or postnatal in origin and may be inherited or acquired. Their recognition and evaluation requires a thorough knowledge and evaluation of the normal chronology of the human dentition and of the normal development and structure of the teeth. Disorders of development of teeth of teeth may be due to abnormalities in the differentiation of the dental lamina and

I was a bit skeptical when I selected Environmental Science class to satisfy my requirement for a Natural Science class‚ however‚ this class has intrigued me and is more interesting than I expected. I have learned a lot about the environment‚ and I really enjoyed learning about ecosystems and the interaction between the biotic and abiotic of ecosystems. I found the earth’s major biomes particularly interesting‚ and would like to reflect on them. According to the text book‚ a biome is a large‚ relatively

Temperate forests animals may migrate‚hibernate‚or store food to survive cold conditions. The average temperature in temperate deciduous forests is 50°F (10°C). Summers are mild‚ and average about 70°F (21°C)‚ while winter temperatures are often well below freezing. PLANTS: Trees and plants in deciduous forests have special adaptations to survive in this biome

With the exception of the lower jaw bone and the ear bones‚ all skull bones are joined together and fixed in one position. The seams where they join are known as sutures. The bones of the skull are classified as either cranial or facial bones. Cranial Bones. The cranium is formed by eight major

Deciduous forests are closer to the equator than the coniferous forests of the tiaga‚ and so they have a longer growing season. This gives the plants more time to produce food‚ and the forest yields about 6000 Kilocalories per square meter per year for animals to eat. These primary producers form the first trophic level. The trees in the deciduous forest shed their leaves in winter. This prevents their branches from being broken by the weight of the snow‚ but also means that they have to grow leaves

A very few species in four main genera are found: the evergreen spruce (Picea)‚ fir (Abies)‚ and pine (Pinus)‚ and the deciduous larch or tamarack (Larix). In North America‚ one or two species of fir and one or two species of spruce are dominant. Across Scandanavia and western Russia the Scots pine is a common component of the taiga.
