Mendel is the father of modern genetics, but there are some genetic characteristics that cannot be explained by simple Mendelian genetics

Part 1: Genetics Problem- Human Blood Types Mendel is the father of modern genetics, but there are some genetic characteristics that cannot be explained by simple Mendelian genetics. Such is the case with the human blood types in which there are 3 alleles for the same gene, A B, and o. A parent can pass allele A, B, or o to the offspring based on the parent’s genotype. From these 3 alleles, there are 4 blood types (phenotypes): A, B, AB, and O, and there are six genotypes: AA, Ao, BB, Bo, AB, or oo. This is an example of codominance in which both A and B alleles are codominant to each other. Blood types can be used in forensics to determine if blood is from the victim or criminal.

According to the Theory of Evolution, Natural Selection is the mechanism by which evolution occurs

According to the Theory of Evolution, Natural Selection is the mechanism by which evolution occurs. The process of Natural selection is based on the following four postulates (listed in your textbook on page 288): Postulate 1 - Individual members of a population differ from one another in many respects. Postulate 2 – At least some of the differences among members of a population are due to characteristics that may be passed from parent to offspring. That is, they are heritable or genetic. Postulate 3 - In each generation, some individuals in a population survive and reproduce successfully but others do not. Postulate 4 – The fate of individuals is not determined by luck.

Find an angiosperm that has modified roots

1]. Find an angiosperm that has modified roots 2]. Explain how this structural modification helped the plant adapt to its environment Angiosperms (flowering plants) are the largest Phylum in the Plant Kingdom (Angiospermophyta is also called Anthophyta or Magnoliophyta). These plants have true roots, stems, leaves and flowers. The roots grow into the soil to anchor the plant in place and take up water and nutrients. With these anatomical features in mind, do some research to find an angiosperm that has modified leaves, stems, roots or flowers that do not function in the normal manner, or that function in an unusual manner. Example: A California Barrel Cactus has spines in place o... click for more

Cellular respiration and photosynthesis co-exist as paired metabolic processes.

Details: Cellular Respiration and Photosynthesis co-exist as paired metabolic processes. Photosynthesis uses light energy to convert carbon dioxide into glucose, a simple sugar, in two steps, the light dependent and light independent reactions. Oxygen is produced as a by product during photosynthesis. This reaction stores energy in the chemical bonds of glucose. Sugar and other carbohydrates are used as fuel sources by cells. During the process of Aerobic Cellular Respiration, glucose is broken down using oxygen. This reaction releases energy which is used to create ATP molecules, the energy carrier molecule of cells. The process also releases Carbon Dioxide as a byproduct. Part 1: ... click for more
