THE KEY ROLES OF CELL DIVISION The ability of organisms to reproduce best distinguishes living things from nonliving matter. The continuity of life is based on reproduction of cells‚ or cell division. In unicellular organisms like amoeba‚ division of one cell reproduces the entire organism. Multicellular organisms depend on cell division for: — Development from a fertilized cell — Growth — Repair Cell division is an integral part of the

Hypothesis: I predict that the leaves taken from the outer area of a shrub have a higher stomatal index (/density) than those taken from the centre of a shrub this are due to light levels. Explanation: Plants have stomata to obtain carbon dioxide from the atmosphere and remove oxygen produced in photosynthesis. During photosynthesis the chloroplasts in the leaf cells synthesize as a result of exposure to light‚ while oxygen is produced as a by-product. As the outer leafs are exposed to higher light

Study Questions: Chapter 28 1.) Archaea and Bacteria are the oldest‚ structurally simplest and most abundant forms of life. 2.) Name and describe seven ways in which prokaryotes differ substantially from eukaryotes? Unicellularity- fundamentally single-celled Cell Size- can vary (large range changes with species) Nucleoid- lack a membrane-bound nucleus but rather a nucleoid region Cell Division/Genetic Recombination- binary fission (does not use spindle) and do not have a sexual cycle Internal

Functions of Management There are four different functions of management. In this paper‚ I will define these functions; planning‚ organizing‚ leading and controlling. I will also explain how each of these functions relates to my own organization.

Task 3: In order to modify the circuit that we created in TASK2 by adding the capacitors C1‚ C2 and C3 and fixing the value of R2 to be 10K‚ as shown in figure. We were asked to calculate the voltage gain of the amplifier for the two different values of Rc. Figure 2 Source: Figure 2 Source: In this task we used the function generator to produce a sine wave of 30mV and 50mV Vp-p at the frequency of 50 KHz. We connected CH1 to fed this generated signal in the oscilloscope at Vin. In

INTENTION We would first need to establish if there is a valid and legally binding contract formation between Iris (“the offeror”) before deciding on the likely outcomes for the parties. A proper contract constitutes an offer‚ an acceptance‚ the provision of a consideration of value and parties’ intention to legal relations. There was no depute as to the presence of a valid offer because Iris did indeed make an offer to sell the piano for a specific price and its terms i.e. keeping the offer open
