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

follows. Allah says in the Qur’an (30:25) To Him belongs whatever is in the heavens and the Earth…and it is He who originates creation”. This quote shows how Muslims believe that the whole of creation‚ the work of one ‘Originator’‚ works within a pattern. All of these parts‚ which include humankind‚ plays their own diverse roles‚ and in doing so assists all other parts. The Qur’an guides adherents on the path to moderation‚ balance and preservation instead of being selfish. It is the path between

Essay on Evolution There are many mechanisms that lead to evolutionary change. One of the most important mechanism in evolution is natural selection which is the differential success in the reproduction of different phenotypes resulting from the interaction of organisms with their environment. Natural selection occurs when a environment makes a individual adapt to that certain environment by variations that arise by mutation and genetic recombination. Also it favors certain traits in a individual

pattern recognition In machine learning‚ pattern recognition is the assignment of a label to a given input value. An example of pattern recognition is classification‚ which attempts to assign each input value to one of a given set of classes (for example‚ determine whether a given email is "spam" or "non-spam"). However‚ pattern recognition is a more general problem that encompasses other types of output as well. Other examples are regression‚ which assigns a real-valued output to each input; sequence

device. The glass bottle should not break‚ so this needed to be taken into account when deciding on a design for our sorter. The sorter also had to be less than or at 1m x 1m x 50cm in size. The sorter needs to be safe‚ creative‚ sustainable‚ be under $100 in total cost for the design‚ and be able to sort the materials fast. This document explains the process of the final design came to be‚ the materials used to construct the final design and the process to sort a glass bottle‚ tuna can and a plastic

Male System The structure and function of the human male reproductive system‚ is very similar to that of many other mammals. The male system is designed to make sperm or male gametes and is adapted to provide for the delivery of these gametes to the female to allow for fertilization.

Evolution is a theory in which organisms change over time and become either better or more complex. ( 1 ) Charles Darwin‚ the Father of the Theory of Evolution‚ discovered that similar birds had adopted different beaks (finches 2 ). And thus‚ the theory of evolution‚ already placed in Darwins head by his grandfather‚ (
