Unit 2 Lecture Study Guide 1) What are the parts of an atom? Where are the subatomic particles found? Parts of an atom- divided into two basic regions: 1. the central nucleus (contains heavy particles) 2. the electron cloud (contains very light‚ moving particles) Subatomic particles: 1.Protons (found in the central nucleus) 2.neutrons (found in the central nucleus) 3.electrons (spin rapidly in a cloud around the central nucleus) 2) How does the Atomic Mass # differ from the Atomic

synthesis occurs and a copy of the DNA is made in the nucleus. G2 is known as the Second Gap Phase where the cell grows and prepares for cell division. G1‚‚S‚ and G2 phases all make up interphase of cellular division. During the M phase‚ mitosis and cytokinesis occurs. In mitosis‚ 4 stages of cellular division occur: prophase‚ metaphase‚ anaphase‚ and telophase. In cytokinesis‚ the cytoplasm of the cell splits‚ making 2 new cells. The G0 phase is known as the resting state. This is where cells are not actively

to undergo a mitosis process. This is the way eukaryotes can replicate themselves into two genetically identical cells (Wikipedia‚ Mitosis). Contrastingly‚ prokaryotes do not have a nucleus and a centrosome‚ so they usually reproduce by binary fission. Comparing the speed of these processes‚ prokaryotic cells can reproduce many times faster than a eukaryotic cell. It takes a relatively more time for a eukaryotic cell to prepare for a division (Julita (2011)‚ Difference Between Mitosis and Binary

Chapter 13: Meiosis and Sexual Life Cycles 1) Genes are the units of heredity‚ and are made up of segments of DNA. 2) In asexual reproduction‚ one parent produces genetically identical offspring my mitosis. In sexual reproduction‚ two parents give rise to offspring that have unique combinations of genes inherited from the two parents. 3) Humans have somatic cells‚ which are any cell other than a gamete‚ have 23 pairs of chromosomes. A karyotype is an ordered display of the paired of chromosomes

Franscesco Redi used a microscope to observe that flies do not spontaneously appear but develop from eggs laid by other flies. Many years later‚ Robert Brown observed a large body in

Adenosine Triphosphate Adenosine triphosphate (ATP) is considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need to do just about everything we do. It is present in the cytoplasm and nucleoplasm of every cell‚ and essentially all the physiological mechanisms that require energy for operation obtain it directly from the stored ATP. (Guyton) As food in the cells is gradually oxidized‚ the released energy is used to re-form the ATP so
