Asexual Reproduction in Animals Group 3 Nina Bansil Kenneth Calabia Josef Franz Cruz I. Introduction Asexual reproduction is reproduction which does not involve meiosis‚ ploidy reduction‚ or fertilization. Only one parent is involved in asexual reproduction. A more stringent definition is agamogenesis which refers to reproduction without the fusion of gametes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaea‚ bacteria‚ and protists

Chapter 1: Intro Independent Variable - variable you deliberately change during an experiment Theory - explanation based on a large number of experiments Hypothesis - educated prediction of cause and effect - what you test in an experiment Control - a zero or set form of the independent variable Dependent - variable you measure because you think it could change 7 characteristics: order‚ regulation‚ growth and development‚ energy processing‚ response to the environment‚ reproduction‚ evolutionary

Substrate concentration pH shifts Temperature shifts Competitive inhibition Describe in detail the process of meiosis as it occurs in an organism with a diploid chromosome number of 4 (2n = 4). Include labeled diagrams in your discussion. Indicate when and how each of the following occurs in meiosis. a. b. Crossing over Nondisjunction 3. In humans‚ discuss the transport of gases (oxygen and carbon dioxide) by the blood and the exchange of these gases

What is Biological Psychology? It is the study of the physiological‚ evolutionary‚ and developmental mechanisms of behavior and experience. It is synonymous with the terms biopsychology‚ physiological‚ and behavioral neuroscience. Much of biological psychology is devoted to studying brain functioning. Physiology is the study of body processes- the dynamic of tissue and organ system of the body. It is the study of the physiological basis of human and animal behavior. Areas of Biological

Major Chemical Properties for Cellular Respiration: We need oxygen at the cellular level for this to be complete. Why do you need oxygen? What is your body trying to do? Your body needs to produce energy‚ which is why you go through these metabolic processes‚ and that’s ultimately why you need oxygen. So we are trying to produce ATP as our energy source. So ultimately your energy cannot be created‚ it only changes form‚ so where does that energy come from in your body? We’re going to convert it into

EXAM1 Q1. How many chromosomes are in a typical red blood cell taken from a normal person? Zero Q2. The degree to which a trait is expressed in individuals is the expressivity of the trait. Q3. In pedigrees‚ a male individual is symbolized as a square. Q4. The chromosomal structure that anchors the spindle fiber to the chromosome is centromere. Q5. The short arm of a submetacentric chromosome is symbolized as the p arm. Q6. Genetic diseases transmitted only by a mother to both sons and daughters

I. Describe the structure and function of the nucleus and mitochondria. The mitochondria is a semi-autonomous organelle which reproduces by bynary fission and has its own DNA. Its main function is to produce the energy intermediate ATP‚ through ATP synthase. Mitochondria could be considered a cell inside a cell. It has its own membranes (inner and outer membranes)‚ its ribosomes (to produce the proteins encoded in its DNA)‚ a matrix -- where aerobic respiration occurs. The invaginations of the inner

1. Allele-One of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome Example: Most multicellular organisms have two sets of chromosomes‚ that is‚ they are diploid Example: Allelic variation at a locus is measurable as the number of alleles present‚ or the proportion of heterozygotes in the population. 2. Gene-A unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring
