Big Idea 2 Biological systems utilize free energy and molecular building blocks to grow‚ to reproduce and to maintain dynamic homeostasis. Living systems require both free energy and matter to maintain order‚ grow and reproduce. Organisms employ various strategies to capture‚ use and store free energy and other vital resources. Energy deficiencies are not only detrimental to individual organisms; they also can cause disruptions at the population and ecosystem levels. Biological systems must both

Our assignment is about how chromosomes separate and how cell division works through microtubules and histones. DNA in the nucleus is loose and not well defined into chromosomes because it is usually tightly coiled‚ but in the interphase nucleus the chromatin exists in two forms: loosely coiled form called euchromatin and tightly coiled formed called heterochromatin. These two types become more coiled to form the chromosome at the time of cell division. DNA is a bit loosely coiled in the euchromatin

LIFE is too short and time is very valuable for everyone. Unfortunately‚ many of us waste time in many ways and when we realise that life could be different and could be led in a much better way‚ it is already too late. It is always wise to have aim in life since one’s childhood-this may be very helpful for one to lead life in a very fruitful way. Having aim fixed helps one work with all his or her energy. A big ship with a good captain departs the port with the tank full of oil but it does not

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 cell cycle‚ the life of a cell from formation to its own division. CELL DIVISION RESULS

These were placed on a study board were the long and l short axis of the sediments were measured by the use of large ruler and tape measure then the samples were recorded. The velocity at these localities two and three were obtained by measuring the velocity (speed) of the river. This was done by two students
