This is ME!

Filed under: AYE AYE =PpP — avaintex @ 11:42 am

Hello there WORLD.

ive always wanted to create a word-press account for me !!!  in fact i always read others posts and ideas about millions of things and today i had the chance to do it , why today ?? why i didn’t create one for my self BEFORE.  -here comes some  information you will get about me-

im a very hard working student i study molecular biology as a major that is why i don’t have enough  time for -online activities- i only check what others speak off about.

i live in Kuwait which is in the middle east , sometimes i get a huge exclamation mark on my face because when i tell some ppl online that im from kuwait they get a huge question mark on their faces and they go like .. KUWI…?? that’s  a main dish in tang chao ? it is really weird  , in our schools here in kuwait we study about the modern and ancient  history in Europe , Americas, Africa , Asia and Australia.We study English as the second language and the majority of private schools are bilingual also, student who chose Literature major in their high school years study french.we are in the third world as its claimed ..shouldn’t we be the ppl with less hints about the whole world?.. its really weird lol.

What else should i mention in here too :P – thinking-

Yes, My interests to be honest with you guys my interests are always changeable , but what i really like is bird they are my passion i love watching bird migrate , like i always check for the migrated birds in the calender and i go spot their behavior and moves i know it sounds boring  to some of you and if its something new for you , why not give it a try and be around nature =P , Please be aware of bears ,snakes , bees and all wild animals when your in the wilds exploring and meditating.

i also like video games especially legend of zelda for wii, i can’t wait for the release of next series of legend of zelda also DS,ps2 , ps3 , game gear , n64 and old Sega genesis  games.

Im  into knitting and sewing , i love bicycles i always wanted one but i don’t think i will get one now!! :( , i like reading but i don’t read extra books besides my college books , because as you know people i don’t have time , i have 3 laboratory classes in 3 days a week which starts at 2 pm and ends at 5 pm and in higher courses i will have 7 hours laboratory , we study about Genes and everything =D lol it is really fun i love what i do and thats important.

Im athletic , football is what im good at .. but since we  don’t have national football team for women i only play for life , i can do a couple of tricks .. yes i think i can =PpPpP

Naturally im social , i like to socialize with people i go to family and to my friends events and i respect my parent they are my world , i listen to them and never complain and nag about things even small things,yesterday i was watching brat camp ive seen unpleasant scenes a  teen(also adults) always hit his mother ,drink and the other want to get revenge  because his mom got the divorce papers and dad is broke and yes i couldn’t forget this teenager he was raped and he is all angry and he always asks”why me?” too much drama,These kids should know that what happen yesterday was from the past you learn from it but you never let it effect your whole life what happened yesterday stays in yesterday,for example if you had this big important exam and you were in the middle of the test writing and you wrote a wrong point in the answer sheet ..wouldn’t you erase it and write the RIGHT answer back?? you can’t write your right answer above the wrong one  because you will not be able to do it , you have to Erase the wrong one and replace it with the new right point and thats what im trying to deliver to you guys ..I know sometimes words kills more than being kicked physically.

scientific methods : The ways in which biologists carry out experiments and make discoveries

Filed under: AYE AYE =PpP — avaintex @ 6:59 pm

The Process of Science

  1. Scientific Method
    1. Biology is the scientific study of life, and it consists of many disciplines.
    2. The scientific process differs from other ways of learning in that science follows the scientific method, which is characterized by observation, development of a hypothesis, experimentation and data collection, and forming a conclusion.
  2. Observation
    1. Scientists believe nature is orderly and measurable, and that natural laws (e.g., gravity) do not change with time.
    2. Natural events, called, phenomena can therefore be understood from observations.
    3. Scientists also use the knowledge and experiences of other scientists to expand their understanding of phenomena.
    4. Chance alone can sometimes help a scientist get an idea (e.g., Alexander Fleming’s discovery of penicillin).
  3. Hypothesis
    1. Inductive reasoning allows a person to combine isolated facts into a cohesive whole.
    2. A scientist uses inductive reasoning to develop a possible explanation (a hypothesis) for a natural event; the scientist presents the hypothesis as an actual statement.
    3. Scientists only consider hypotheses that can be tested (i.e., moral and religious beliefs may not be testable by the scientific method).
  4. Experiments/Further Observations
    1. Testing a hypothesis involves either conducting an experiment or making further observations.
    2. Deductive reasoning involves “if, then” logic to make a prediction that the hypothesis can be supported by experimentation.
    3. An experimental design is proposed to test the hypothesis in a meaningful way.
    4. An experiment should include a control group which goes through all the steps of an experiment but lacks (or is not exposed to) the factor being tested.
    5. Scientists may use a model (a representation of an actual object) in their experiments.
    6. Results obtained from use of a model will remain a hypothesis in need of testing if it is impossible to test the actual phenomenon.
  5. Data
    1. Data are the results of an experiment, and are observable and objective rather than subjective.
    2. Data are often displayed in a graph or table.
    3. Many studies rely on statistical data which, among other things, determines the probability of error in the experiment.
  6. Conclusion
    1. Whether the data support or reject the hypothesis is the basis for the conclusion.
    2. The conclusion of one experiment can lead to the hypothesis for another experiment.
    3. Scientists report their findings in scientific journals so that their methodology and data are available to other scientists.
    4. The experiments and observations must be repeatable or the research is suspect.
  7. Scientific Theory
    1. The ultimate goal is to understand the natural world in scientific theories, which are speculative ideas that join supported, related hypotheses, and are supported by a broad range of observations, experiments, and data.
    2. Some basic theories of biology are:
      1. Cell: all organisms are made of cells.
      2. Homeostasis: the internal environment of an organism stays relatively constant.
      3. Gene: organisms contain coded information that dictates their form, function, and behavior.
      4. Ecosystem: organisms are members of populations which interact with each other and the physical environment.
      5. Evolution: all living things have a common ancestor.
    3. A principle or a law is a theory that is generally accepted by most scientists.
  8. A Controlled Study
    1. A controlled study ensures that the outcome is due to the experimental (independent) variable, the factor being tested.
    2. The result is called the responding (dependent) variable because it is due to the dependent variable.
    3. The Experiment
      1. Hypothesis: pigeon pea/winter wheat rotation will increase winter wheat production as well as or better than the use of nitrogen fertilizer.
      2. Prediction: wheat biomass following the growth of pigeon peas in the soil will surpass wheat biomass following nitrogen fertilizer treatment.
      3. Control group: winter wheat that receives no fertilizer.
      4. Test groups: winter wheat treated with different levels of fertilizer; winter wheat grown in soil into which pigeon pea plants had been tilled.
      5. Environmental conditions and watering were identical in control and test groups.
      6. Results: all test groups produced more biomass than control group, but high level of nitrogen fertilizer produced more biomass than pigeon pea test group. Thus, hypothesis is not supported.
    4. Continuing the Experiment
      1. To test the hypothesis that pigeon pea residues will build up over time and will increase winter wheat production compared to nitrogen fertilizer, the study is continued for another year.
      2. The fertilizer-only treatment no longer exceeded biomass production with the use of pigeon peas; biomass in the pigeon pea-treated test group was highest.
      3. Conclusion: at the end of two years, the yield of winter wheat is better in the pigeon pea-treated test group. Hypothesis supported.
      4. Continuation of the study for another year showed that the soil was continuously improved by the pigeon peas compared to the nitrogen fertilizer test groups.
      5. Results were reported in a scientific journal.
  9. A Field Study
    1. Hypothesis: aggression of the male mountain bluebird varies during the reproductive cycle.
    2. Prediction: aggression will change after the nest is built, after the first egg is laid, and after hatching.
    3. To test the hypothesis, a male bluebird model was placed near the nest while the male was gone and observations were made upon his return.
    4. Control: a model of a male robin placed near certain nests.
    5. Results: resident male bluebirds did not bother the control model but were aggressive toward the male bluebird model depending on the stage in the reproductive cycle.
    6. Conclusion: hypothesis is supported.
    7. Study was reported in scientific journal with evolutionary interpretation.

Aspirin

Filed under: AYE AYE =PpP — avaintex @ 9:29 pm

Aspirin (Acetylsalicylic acid) its an acid that is formed by the addition of Salicylic acid and acetic anhydride in the presence of an acid catalyst like phosphoric or sulfuric acid and we all know that catalyst are used to speed up the reaction and increase the yield of reaction.
