    1. Which of the following is true about the cells in a multicellular organism? (1 point)The cells contain different genes and therefore express different genes. The cells contain different genes, so they express only the genes they have in common. The cells contain the same genes but do not express the same genes. The cells contain the same genes and express the same genes. 2. If a scientist changes the path of differentiation in some cells by adding a growth factor, what process is involved? (1 point)fertilization induction cytoplasmic localization apoptosis 3. Which of the following shows the correct order of extent of differentiation? (1 point)multipotent, totipotent, pluripotent totipotent, multipotent, pluripotent pluripotent, totipotent, multipotent totipotent, pluripotent, multipotent 4. Which of the following is the function of adult stem cells? (1 point)provide a safeguard in case a limb transplant is needed provide a reservoir of cells for making gametes provide a source of cells for the body to replace certain types of cells that die provide a backup set of cells that can be used to grow replacement cells in culture

    I think the answers are 1c, 2b, 3c, 4c. To explain a little bit: Q2: you don't get any more potent than totipotent - that means that a stem cell can make any cell in the body. Pluripotent means that any of the three major types of cells can develop: either endodermal, mesodermal or ectodermal. A Multipotent cell can develop into many types of cells of the same lineage - like haematopoeitic stem cells that can form many different types of blood cells. To cut a long story short it's totipotent, pluripotent then multipotent. Q4: adult stem cells can replace worn out cells - some cells are continuously replaced like red blood cells and some gut lining cells

    let me just say the question 2 has changed from: If a scientist changes the path of differentiation in some cells by adding a growth factor, what process is involved? TO: in order for a gene to be transcribed or read,what needs to happen? so the answers to the questions now are 1.C 2.A 3.D 4.C hope this helps to those who need it:)
