    meiosis:

    prophase 1:

    the chromosomes condense becoming shorter and thicker, they can be stained and viewed under a light microscope. Homologous chromosomes pair up to form a bivalent. the non sister chromatids wrap around each other and attach at points called chiasmata ( singular chiasma) They may swap sections of chromotids with one another in a process called crossing over. spindle fibres move to opposite poles and produce spindle fibres.The nuclear envelop breaks down.

    Habituation- remember getting into the habit to help. Learning to ignore a stimulus because of repeated exposure gives neither reward not punishment.

    Classical Conditioning- remember Pavlov and the dog. Food= Dog salivating. Food+ Bell+ Salivating. After many times just Bell= Salivating. It has become a conditioned response

    Operant Conditioning- Trial and Error Learning, e.g. a monkey learns to press a button because he gets a treat/ learns not to press it because it electrocutes him.

    Latent Learning- exploring and remembering stuff incase it comes in handy.

    Insight Learning- Logic. Human and some primates have it. Thinking and Reasoning e.g. Monkey building up boxes to get to banana's.

    Habituation is when animals learn to ignore certain stimuli becuase repeated exposure to the stimuli has resulted in no reward nor punishment

    Classical conditioning is when an uncondisioned stimulus is associated with a conditioned stimulus which results in a conditioned response. This means animals can learn to relate a pair of events together

    Operant learning is when an animal learns to carry out a particular task in order to receive a reward or avoid a punishment

    Latent learning is when an animal explores its new surroundings and retains this information for use when in situations of danger (predators)

    Insight learning is the ability to think and reason in order to solve problems or deal with situations in a way that does not resemble simple reflexes. Once solved the solution is remembered

    Righty ho then.
    Habituation: where the organism learns to get used to a stimulus (eg people living near busy roads) as it doesnt pose a threat, thereby conserving energy and less stress
    CLassical con: Learning to associate one stimulus with another, eg Pavlov's dogs. When fed saliva was produced. Then a bell was rang while the dogs were fed. Soon when the bell was rung, the dogs began to salivate in anticipation of food
    Operant: Learning to do something/not do something for pleasure/pain. Eg rat in box accidently pushes lever, food comes out. Soon the rat pushes the lever because it associates it with food.
    Latent: Exploring surroundings in case it may save their life in emergency situation (eg baby rabbits learning their warrens)
    Insight: Highest form of learning, reasoning, lack of trial and error, problem solving. Once the problem is solved, the solution is 'saved' for future reference.

    Hope that helps, took ages to type

    Yeah ill do it, btw up for msn sess only if people are willing to give out their MSN's haha :P

    Anyway.

    HW principle is simple, it states that if nothing is taken out or put into the system then the allele frequency from one generation to the next should be the same.
    p + q = 1
    P^2 + q^2 + 2pq = 1 where q^2 = the frequency of the recessive allele in a population. 2pq = heterozygous individuals.

    It only holds true if there is:
    -a large population
    -no immigration, no emigration, no genetic drift or mutation
    -Random Mating
    -No selection pressures

    Btw for muscles theres bands (I and A), lines (M and Z) and theres one zone, the H zone I,A,Z and H all get smaller during contraction, only A and M remain the same.

    Sure: It basically relates all the different genotypic ratio. i.e estimation of allele frequencies
    so p^2+2pq+q^2 =1 where
    p = Homo dominant allele, Q: Homo recessive allele and PQ: Hetero.
    Sorry kind rushed it (multitasking) :/
    p = the frequency of the dominant allele (represented here by A)
    q = the frequency of the recessive allele (represented here by a)

    For a population in genetic equilibrium:
    p + q = 1.0 (The sum of the frequencies of both alleles is 100%.)


    For any further question post it up and quote me back
