DSD 251 Oral Biology and Histology 2 DENTAL PULP: (Origin-Functions and Anatomy-Histology Vascularity and Lymphatic supply –Nerve supply. Regressive changes of the pulp: fibrous changes pulpal stones –diffuse calcifications) DEFINITION : The pulp is a delicate mesenchymal connective tissue that occupies the pulp cavity in the central part of tooth. The normal pulp is pink‚ coherent soft tissue is noted‚ dependent on its normal hard dentin for protection. Dentin and pulp are embryologically‚ histologically

BIOLOGY 207 SIMULATOR ASSIGNMENT MULLIS POPULATION WRITTEN RESULTS SECTION In vial one‚ a wild type hyper female Drosophila and wild type mellow male Drosophila were crossed respectively to determine the dominant behavioural phenotype. The first reciprocal cross was then carried out in vial two to define whether or not the behavioural phenotype is x-linked recessive. According to the results obtained from vial one‚ when the wild type hyper female and wild type mellow male was crossed‚ the resulting

Last Monday‚ (August 15‚ 2011) we had our Environmental Biology Field trip at three different places all around Manila‚ We visited The Avilon Zoo‚ The La Mesa Eco Park and The Myth of the Human body. We are scheduled to depart at around 6:00 in the morning because that is what’s written in our itinerary‚ but just like what we all expected‚ the bus started the engine at around 7:30 in the morning already‚ we were kind of left behind with our scheduled trip and we’re a little bit upset about it because

Principles of Biology I Exam 4 Review Questions 1. What is the difference between a genotype and a phenotype? 2. Write the genotype of a homozygous recessive‚ homozygous dominant‚ and heterozygous pea plant using the trait flower color (p). 3. Different versions of a gene are called ____________. 4. Why are there always two alleles present for each gene at a specific locus? 5. True or False. A dominant allele is always written with a capital letter‚ whereas the recessive allele

Biology - Final Review (50 Questions) Scientific Method Observations: New observations are made and past data are studied Hypothesis: A testable statement is formulated Experiment/Observations: The hypothesis is tested by experiment of further observations Conclusion: The results are analyzed. • If the hypothesis is support. Continue work (multiple experiences) • If the hypothesis is rejected. Start again (new hypothesis) Car Scenario: Observations: Vehicle won’t start Hypothesis:
