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)

-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

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

meiosis is the correct answer
