unjust. An ongoing problem with human rights is the violation of freedom to slavery. This virtue is mentioned in Article four of the declaration of human rights. This right is important because it gave African Americans the chance to live their own life without being seen as goods or tradable material. Since the beginning of the United States to the end of the Civil War‚ slavery has been a major factor in America’s past. The definition of slavery is Throughout human history‚ humans have been

Essay Question 1 Explain how changes in habitat can lead to habitat fragmentation. How does this affect the population of animals in that area? Species lose their habitats when those habitats are destroyed outright‚ but habitat loss also occurs when habitats are altered through more subtle processes‚ including fragmentation and other forms of degradation. The sudden and complete elimination of habitat is uncommon at large scales; instead‚ what we usually witness is gradual‚ piecemeal degradation

hypothesis‚ essential to the most popular hypotheses about the origin of life on Earth? The origin of life on Earth is said to be from a single organism‚ which branched out to create everything there is today. A universal genetic code takes the similarities in organisms and compares them to suggest that each organism came from a single organism from early Earth. Although‚ this is just a theory‚ but can support the beginning of life. 4.How might similarities and differences in genetic codes‚ or the

the number of chromosomes to half so sexual reproduction can occur. 2. This reduction division is known as meiosis. D. The Sexual Life Cycle 1. Adult cells are diploid‚ and gametes are haploid. 2. Sexual reproduction joins haploid gametes to produce a new diploid individual. 9.2 The Sexual Life Cycle (p. 173; Figs. 9.3‚ 9.4) A. Somatic Tissues 1. In the sexual life cycle‚ there is an alternation of diploid and haploid generations. 2. Normal diploid body cells are called somatic cells. 3. Somatic

nitrogenous bases and phosphorus groups. Each has four chemicals which are Adenine‚ Guanine‚ and Cytosine; but here is where is changes: DNA has Thymine and RNA has Uracil. DNA is in all biotic things because one of the seven (or eight) traits of life is cells; which only biotic species contain. For instance‚ a rock doesn’t have cells‚ only minerals; therefore‚ a rock is abiotic. Biotics contain DNA‚ and DNA is made of nucleic acids (which are polymers because they are many). Nucleic acids
