Answer and Explanation:
The correct answer is option B
B. The treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, but the control cells were cultured without the inhibitor.
Most likely an altimeter,
microscopes can be too heavy to carry outside,
x-ray diffraction is used to determine the molecular structure of a crystal so that is not likely to be helpful,
but an altimeter determines the altitude of an object on a fixed level, so that can be useful during a field investigation
hydrometers-measure gravity of liquids, probably not useful for a field investigation
Answer:
The correct option is: C. pump blood with greater pressure
Explanation:
The human heart is a muscular organ, present between the middle compartment of the chest and the lungs. Heart is responsible for pumping blood through blood vessels of the circulatory system. It is divided in the following four chambers: the right atria, left atria, right ventricle and left ventricle.
The wall of the left ventricle is thicker as compared to the wall of the right ventricle. This is because <u>greater force is required to pump the blood to the entire body.</u>
The answer would be B. The available energy would decrease from the mouse to the hawk. As the trophic level goes up the energy decreases because some of the energy is lost in the form of heat for every energy transfer. This energy being lost cannot be used by the organisms on the next level.
