Hypothesis: I predict that the leaves taken from the outer area of a shrub have a higher stomatal index (/density) than those taken from the centre of a shrub this are due to light levels. Explanation: Plants have stomata to obtain carbon dioxide from the atmosphere and remove oxygen produced in photosynthesis. During photosynthesis the chloroplasts in the leaf cells synthesize as a result of exposure to light‚ while oxygen is produced as a by-product. As the outer leafs are exposed to higher light

Genetic Traits Exercise: Introduction: The pioneer of modern day genetics was an Austrian Monk named Gregor Mendel‚ who established the basic laws of heredity from his studies with pea plants in the late 1800s. Mendel’s fundamental genetic principles may be applied to a variety of traits from many different organisms. Each genetic trait‚ such as flower color‚ is regulated by a pair of genes called alleles. These alleles are found at particular places on the chromosomes called loci. During meiosis

Study Questions: Chapter 28 1.) Archaea and Bacteria are the oldest‚ structurally simplest and most abundant forms of life. 2.) Name and describe seven ways in which prokaryotes differ substantially from eukaryotes? Unicellularity- fundamentally single-celled Cell Size- can vary (large range changes with species) Nucleoid- lack a membrane-bound nucleus but rather a nucleoid region Cell Division/Genetic Recombination- binary fission (does not use spindle) and do not have a sexual cycle Internal

to excel on the SAT and in college courses. According to the College Board’s website‚ AP Biology courses are designed to be the equivalent of a college introductory course‚ usually taken during a biology major’s first year of college. Students who choose to take AP Biology may be allowed to skip over introductory biology courses and enroll in courses in which biology is a prerequisite. Because universities grant college credit for this course‚ they require that the textbooks‚ labs‚ and coursework

Challenges in the Field of Marine Biology No matter what science oriented profession one chooses to pursue‚ education is the undisputed key to success and the field of marine biology is no exception. While a bachelor’s degree qualifies you for an entry level position‚ it is most likely insufficient if you have your sights set on a career involving independent research or field work. The majority of people working within the field of marine biology with only a bachelor’s degree‚ are for the

Theories of Biology University of Phoenix – Axia There are seven major theories of Biology that attempt to organize and make sense of the multitude of ideas surrounding the major theories of Biology. The theories include evolution of natural selection‚ inheritance‚ cells‚ biological classification‚ bioenergetics‚ homeostasis‚ and ecosystems. The evolution of natural selection is the theory the theory that attempts to explain how and why species are able to adapt to their environments

Extended experimental investigation: effects on membranes of environmental stress Background It is not possible to observe membranes directly‚ so this investigation is an indirect study of the effects of different substances and treatments on living beetroot cells. Beetroot cells have been chosen for this activity because each beetroot cell has a large central vacuole bounded by a membrane (Figure 1). Contained in the vacuole is the red pigment anthocyanin‚ which gives the beetroot its
