Background DNA is an abbreviation for deoxyribonucleic acid‚ but it is usually known by its initials alone. DNA is found in practically all living organisms‚ and it is now known to carry genetic information from one cell to the next‚ and from one generation to the next. The units of inheritance‚ called genes‚ are actually sections of the DNA molecule. Nuclei of the cells of higher organisms contain thread-like bodies called chromosomes‚ which consist of DNA‚ wrapped around proteins. So understanding how

sexual reproduction 2. multicellularity Many protists reproduce only asexually – mitosis. Some use meiosis and sexual reproduction only in times of stress and then others reproduce sexually most of the time. What unites protists? The kingdom Protista contains all eukaryotes that don’t fit in animals‚ plants and fungi.

Give two differences between mitosis and meiosis. 1 in mitosis the resulting cells of the divsions are clones of the original cell 2 meosis occurs in plants animals and fungi mitosis only occurs in humans.

Unit 2 Lecture Study Guide – 1) What are the parts of an atom? Where are the subatomic particles found? a) Protons‚ neutrons‚ and electrons b) Protons and neutrons are located in the center of an atom in the nucleus and the electrons are located around the nucleus. 2) How does the Atomic Mass # differ from the Atomic #? The atomic mass number is the sum of the number of protons and neutrons in the nucleus of an element and the atomic number is the number of protons that it has. 3)

Members of the Kingdom Plantae share both similarities and differences with members of the Kingdom Animalia. These differences can largely be categorized under the titles cell biology‚ cell growth‚ physiology‚ and development. Regarding cell biology‚ it is important to understand that both categorize their cells as eukaryotic. The Encyclopedia Britannica defines eukaryotes as “any cell or organism that possesses a clearly defined nucleus”. While both cells have a nucleus‚ cytoplasm‚ ribosomes‚ mitochondria
