Nucleic acid structure
These slides provide an introduction to the structure and function of nucleic acids (DNA and RNA) in relation to organisms, genes, gene expression and protein synthesis. It is a basic introduction to DNA, genes and genomes, the chemistry of nucleic acid structure and its various conformations. The slides have a quiz at the end which can be used to evaluate learning outcomes at the end of the lecture. The resource is used in teaching fundamental concepts to first year undergraduate students in
Bacterial Structure - Fill in the Blanks!
A quiz based on bacterial struture in which the student has to 'fill in the blanks' using words selected from a list provided. The filled in answer sheet is also provided. This is a word document.
A series of Articulate Engage presentations that use photographs and graphics to illustrate fungal structure. A guide on how to look at fungi using a light microscope is also included, as is a glossary of terms used in mycology.
The look at the plants themselves - their form and the arrangement of their parts.
12.108 Structure of Earth Materials (MIT)
This course provides a comprehensive introduction to crystalline structure, crystal chemistry, and bonding in rock-forming minerals. It introduces the theory relating crystal structure and crystal symmetry to physical properties such as refractive index, elastic modulus, and seismic velocity. It surveys the distribution of silicate, oxide, and metallic minerals in the interiors and on the surfaces of planets, and discusses the processes that led to their formation. It also addresses why diamonds
Social Structure, Race/Ethnicity, and Homicide
As discussed, the murder rates for Blacks in the United States are substantially higher than those for Whites, with Latino murder rates falling in the middle. These differences have existed throughout the 20th and into the 21st century and, with few exceptions, are found in different sections of the United States.
24.903 Language and its Structure III: Semantics and Pragmatics (MIT)
This course gives an introduction to the science of linguistic meaning. There are two branches to this discipline: semantics, the study of conventional, "compositional meaning", and pragmatics, the study of interactional meaning. There are other contributaries: philosophy, logic, syntax, and psychology. We will try to give you an understanding of the concepts of semantics and pragmatics and of some of the technical tools that we use.
Momodou Ceesay talks about the function of an artist
Gambian artist Momodou Ceesay, painting instructor at the Elma Lewis School of Fine Arts and at Roxbury Community College, talks about his function as an artist and his recent work illustrating African stories for children.
Population: Age Structure
One of the primary tools that demographers use to understand population is the age structure diagram, a graphic representation that shows the distribution by ages of females and males within a certain population.
