CHON (Carbon, hydrogen, oxygen, nitrogen, and are main element…… Deoxyribonucleic acid, or DNA, is a biological macromolecule that carries hereditary information in many organisms. Trophic level: the trophic level of an organism is its position in the food chain. It occurs in the alveoli of the lungs.

Should you major in IB? Both IB Biology SL and HL consist of the same core requirements (95 hours). DNA and RNA both consist of nucleotides which contain a sugar, a base and a phosphate group. Sex linkage: when the gene controlling the characteristic is located on the sex chromosome and so we associate the characteristic with gender. Excretion. emmagclarke. The mitosis steps include preprophase (in plant cells), prophase, prometaphase, metaphase, anaphase, and telophase. Definition noun The deprivation or the process of neutralization of polarity, as that in nerve cells Supplement Depolarization is the process or the act by which polarity is eliminated. Homozygous: having two identical alleles of a gene. Evolution 5.4.1 Define evolution. give the precise meaning of a word, phrase or physical quantity. Linkage group: A pair or set of genes on a chromosome which tend to be inherited together. IB Biology is challenging, college-level biology, so sometimes you will need a little more study help than your class notes provide. While there are core skills and activities common to both SL and HL students, students at HL are required to study the options and some topics in greater depth as well as some additional topics. 2 or more elements combined in a fixed ratio. In physiology, depolarization occurs in a living cell (e.g. Give the precise meaning of a word, phrase, concept or physical quantity. Producers, primary consumers, secondary consumers and tertiary consumers are examples of trophic levels. Oxygen diffuses into the capillaries from the air in the alveoli and carbon dioxide diffuses out of the capillaries and into the air in the alveoli. Here they are (highlight to see): Structure & Function Universality versus Diversity Equilibrium within Systems Evolution They are on page 40 on the subject guide. 6.4.1 Distinguish between ventilation, gas. The science of life and of living organisms, including their structure, function, growth, origin, evolution, and distribution and encompassing numerous fields such as botany, zoology, mycology, and microbiology.
