    1. the Law of Dominance
    2. the Law of Segregation
    3. the Law of Independent Assortment

    Is their a specific order?

    anyways...role of chlorophyll in photosynthesis?

    I apologise. I must have it confused with something else:o So what are the four stages?

    Bile - bitter greenish alkaline fluid secreted by the liver and stored in gall bladder. discharged during digestion where it aids emulsification and absorption of fats.:D

    No! Mitosis only involves 2-5. It is a nuclear division, not a cell division, and no division takes place whatsoever during Interphase.

    What are the differences between a Monocyte and a Lymphocyte?
    Monocytes are phagocytic (i.e they ingest foreign particles) and migratory.
    Lymphocytes produce B-Cells (antibodies and memory cells) and T-Cells (killer, helper, suppressor, memory).

    Immobilised enzymes are enzymes that are attached, or fixed,to each other or to an inert material.

    A transgenic organism contains genes from another species.

    Mendel's Law Of Segregation states that inherited characteristics are controlled by pairs of factors (alleles) and these factors segregate at gamete formation so that one one factor is carried in each gamete.

    State Mendel's Second Law.
