2. In laboratory testing using a HER2-positive breast cancer cell line, the researcher has seen early success with the new treatment. In the lab, the researcher incubated the HER2-positive cell line in a petri dish. After the cells had time
to grow, they were treated with a dose of Herceptin. The number of cells that had undergone apoptosis, or cell death,
was then examined to determine the effectiveness of the treatment. Examine the data collected below then calculate
the mean. Go to the next page to finish formatting the graph, then add the mean that you calculated as a bar to the
graph. (*note: we will be adding more to the graph as you progress through the questions).

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
