AP Biology Summer Assignment Chapter 50.1: An Introduction to Ecology and the Biosphere Ecology is the scientific study of how organisms interact with the environment. When studying Ecology scientists want to know‚ where organisms live‚ why they live there‚ and how many are there. Ecology and environmental biology both stem from Darwin’s interest and observations upon the distribution of organisms and how they adapted to their specific environment. Darwin concluded that the environment interacting

AP biology FRQ Courtney DeMane 1.22.13 block 7 A). The chemical composition and structure of proteins seems quite confusing at first but one it is broken down into levels it is much more understandable. Amino acids are the basic building blocks of proteins and they contain amino‚ carboxyl and R groups. These R groups that are in the amino acids are what determine the properties of the specific amino acids. For structure‚ there are 4 levels. The first one being the primary level. These are made

Chapter 13: Meiosis and Sexual Life Cycles 1) Genes are the units of heredity‚ and are made up of segments of DNA. 2) In asexual reproduction‚ one parent produces genetically identical offspring my mitosis. In sexual reproduction‚ two parents give rise to offspring that have unique combinations of genes inherited from the two parents. 3) Humans have somatic cells‚ which are any cell other than a gamete‚ have 23 pairs of chromosomes. A karyotype is an ordered display of the paired of chromosomes
