Read our subject-specific articles on topics varying from the photosynthesis equation to homologous and analogous structures to cell biology (including cell theory, enzymes, and how the cell membrane and endoplasmic reticulum work). Gas exchange in humans HCG stimulates the ovary to secrete progesterone during early pregnancy. Most flowering plants use mutualistic relationships with pollinators in sexual reproduction. The liver removes toxins from the blood and detoxifies them. Villi absorb monomers formed by digestion as well as mineral ions and vitamins. Different methods of membrane transport are required to absorb different nutrients. Energy released by oxidation reactions is carried to the cristae of the mitochondria by reduced NAD and FAD. Both classes cover the same six topics in the order listed below with the same subtopics listed below: She loves watching students succeed and is committed to helping you get there. Steroid hormones bind to receptor proteins in the cytoplasm of the target cell to form a receptor–hormone complex. A gene pool consists of all the genes and their different alleles, present in an interbreeding population. The type of stable ecosystem that will emerge in an area is predictable based on climate. Peptide hormones bind to receptors in the plasma membrane of the target cell. The neural tube of embryonic chordates is formed by infolding of ectoderm followed by elongation of the tube. The left cerebral hemisphere controls muscle contraction in the right side of the body and vice versa for the right hemisphere. She graduated magna cum laude and scored in the 99th percentile on the ACT. Molecular biology explains living processes in terms of the chemical substances involved. The binomial system of names for species is universal among biologists and has been agreed and developed at a series of congresses. Crossing over and random orientation promotes genetic variation. The plasticity of the nervous system allows it to change with experience. Oxygen dissociation curves show the affinity of hemoglobin for oxygen. There is a delay between the arrival and passing on of a stimulus at the atrioventricular node. Recombinant DNA must be inserted into the plant cell and taken up by its chromosome or chloroplast DNA. An action potential consists of depolarization and repolarization of the neuron. The loop of Henle maintains hypertonic conditions in the medulla. DNA is a double helix made of two antiparallel strands of nucleotides linked by hydrogen bonding between complementary base pairs. Organisms consisting of only one cell carry out all functions of life in that cell. The human cerebral cortex has become enlarged principally by an increase in total area with extensive folding to accommodate it within the cranium. We want to get you admitted to your dream schools. Some genetic diseases are sex-linked. Unsaturated fatty acids can be cis or trans isomers. Conditions are maintained at optimal levels for the growth of the microorganisms being cultured.

Some prokaryotes also have plasmids but eukaryotes do not. DNA replication is continuous on the leading strand and discontinuous on the lagging strand. Disturbance influences the structure and rate of change within ecosystems. Databases can be searched to compare newly identified sequences with sequences of known function in other organisms. Vaccines contain antigens that trigger immunity but do not cause the disease. The volume and content of gastric secretions are controlled by nervous and hormonal mechanisms. 1st Year Zoology (Non-Chordata and Protochordata) Syllabus, T.U. BLASTn allows nucleotide sequence alignment while BLASTp allows protein alignment. Independent assortment of genes is due to the random orientation of pairs of homologous chromosomes in meiosis I. Gene loci are said to be linked if on the same chromosome. Amino acids can be linked together in any sequence giving a huge range of possible polypeptides. Microorganisms are used in bioremediation. The DP curriculum review is a collaborative process that aims to produce excellent, internationally minded, research-based curriculums and support material that enable students to develop the attributes of the learner profile and the IB mission, thereby providing an … Fetal hemoglobin is different from adult hemoglobin allowing the transfer of oxygen in the placenta onto the fetal hemoglobin. Oxygen is needed to bind with the free protons to maintain the hydrogen gradient, resulting in the formation of water. The halving of the chromosome number allows a sexual life cycle with fusion of gametes. Blood flows through tissues in capillaries. In a eukaryote species there are different chromosomes that carry different genes. Genetic modification can be used to overcome environmental resistance to increase crop yields. Testosterone causes pre-natal development of male genitalia and both sperm production and development of male secondary sexual characteristics during puberty. Autotrophs convert carbon dioxide into carbohydrates and other carbon compounds. Not sure where you want to go to college? Some strains of bacteria have evolved with genes that confer resistance to antibiotics and some strains of bacteria have multiple resistance. The IB is a rigorous curriculum, where students strive to be 21st century learners. ATP hydrolysis and cross bridge formation are necessary for the filaments to slide. Immature neurons migrate to a final location. The first cells must have arisen from non-living material.
