BIOLOGY MIDTERM ESSAY 1. How does the biologist determine whether a thing is living or nonliving? Or what characteristics do living organisms have that non-living things do not? They look at it under a microscope and see if it has cells. Basically‚ if it has cells the it’s alive. If it doesn’t have cells it is considered nonliving. There are smaller archaebacteria that behave like small parts of cells. These are considered living too‚ because they have chemical bonds of RNA‚ which is the singular

Lifetime perspective is human development that is determined by factors like genetics‚ socioeconomic status and the life of a person and how people do understand different aspects of life. In addition‚ lifetime is the period that ranges from conception to death. Several things that influence human development are socioeconomic‚ sex‚ heredity‚ nutritional and the hormones in the body. Socioeconomic as a factor is linked with children especially vary in their body sizes. Families with better nutrition

Determining the Crossover Frequency in Sordaria fimicola Introduction Meiosis is an important part of the life cycle that gives rise to the genetic variation in offsprings. Meiosis in fungi differs from those in plants and animals. Fungi are composed of hyphae‚ which are tubules that make up the frame. These hyphae together form a clump or a mat that is the mycelium (Campbell‚ 637). The hyphae are key to fungus reproduction. Typically fungi produce large amounts of spores through either sexual

University of Central Oklahoma CRI-DU-CHAT SYNDROME By James Truby May 3‚ 2006 BIO 2233 Heredity Paper Assignment CRI-DU-CHAT SYNDROME (CDCS) Cri-du-chat syndrome (CDCS) refers to a unique combination of physical and mental characteristics associated with a loss of genetic material on the distal short arm of the fifth chromosome. This loss of genetic material is referred to as a deletion. CDCS is also called 5p- syndrome (5p-S)‚ 5p monosomy‚ or Cat Cry syndrome which was

We learned that our physical traits are called a "phenotype" and that our DNA‚ or genetic make-up is called a "genotype". I now know that one single gene can be responsible for a disorder. I used to think that disorders were caused by multiple problems and not just one gene. Heterozygotes are two non-matching genes and homozygotes are two identical genes. People

argument over whether heredity or the environment has the most impact on human psychological development. In the debate nature refers to human’s genotypes‚ the set of genes inherited from parents. Nurture refers to environment factors an individual is exposed to over time. A phenotype refers to the characteristics resulting from interaction of a genotype with the environment (Carter 192). Generally‚ psychologists argue that who we are is predetermined by our DNA. While sociologists and social and
