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
Premium DNA Chromosome Gene
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

cells arise by division of existing cells Cell division occurs in the nucleus of eukaryotic cells by mitosis and meiosis Replacement of the entire lining of your small intestine Liver cells only divide for repairing Nerve cells do not divide Chromosomes Long and thin for replication and decoding Become short and fat prior mitosis → easier to separate due to compact form Meiosis (reduction division) During the production of sex cells (gametes) in animals In spore formation which precedes

Frederick Griffith | This person made an experiment that involved injecting mice with pneumonia: smooth S cells‚ rough R cells‚ heat-killed S cells‚ and heat-killed S cells with living R cells. | Avery‚ McCarty‚ and MacLeod | First to show that DNA was the genetic material‚ but not believed. Repeated Griffith’s experiment‚ but subjected the strains to different enzymes‚ isolating RNA‚ DNA‚ lipids‚ carbohydrates‚ and proteins. Only the DNA killed the mice; the others had the mice survive. | Hershey

Meghan Veach Bio. 101 Dr. Davis April 28‚ 2014 Chapter 18 - Evolution of Plants and Fungi Plants have been around for over 500 million years‚ the plants all differ so much but they also have many similarities among themselves and also to green algae. Some scholars even think that plants paved the way for land animals by simultaneously increasing the amount of oxygen in the Earth ’s atmosphere and decreasing the amount of carbon dioxide. Evolutionist believe that plants evolved from green

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

Biology‚ 7e (Campbell) Chapter 23: The Evolution of Populations Chapter Questions 1) What is the most important missing evidence or observation in Darwin’s theory of 1859? A) the source of genetic variation B) evidence of the overproduction of offspring C) evidence that some organisms became extinct D) observation that variation is common in populations E) observation that competition exists in populations Answer: A Topic: Concept 23.1 Skill: Knowledge 2) Which hypothesis of inheritance

Estrogens are released which; 1. Proliferate endometrium 2. Thin the cervical mucus 3. Stimulate pituitary to release LH * The LH; 1. Elevate concentrations of maturation promoting factor (oocytes complete meiosis one and begin meiosis II‚ stopped at metaphase) 2. Stimulate progesterone production by follicular stromal cells (luteinisation) 3. Cause follicular rupture Ovulation * High concentration of LH makes the collagenase active breaks down collagen
