Strep throat and bacterial pneumonia are examples of
The correct answer is a. bacterial communicable diseases.
Strep throat is a bacterial infection which has symptoms such as sore and scratchy throat. The causative agent of strep throat is <em>Streptococcus pyogenes </em>and gets spread by contact by the secretions of the respiratory tract of the infected person if the person sneezes or coughs.
The bacterial pneumonia is commonly caused by <em>Streptococcus pneumoniae. </em>The bacterial pneumonia is a community acquired pneumonia. The most common way it is caused when the bacteria aspirates from the oral cavity or by breathing infected air droplets having pneumonia. The bacteria can enter the bloodstream and deposits in the lungs causing pneumonia.

The correct answer is d. complete blood count.
White blood cell count test is used to measure of the white blood cells in the patient's body. This test is included in the complete blood count test. There are different types of white blood cells present in the body and each of it has a specific percentage .
Surface tension is the property of water which allows for some lightweight insects to walk on top of a pond and not fall in. The molecules of water are held together by cohesive forces. The molecules of water present below the surface experience this cohesive force from all the directions, whereas the water molecules present on the surface experience a downward pull, as the force is not balanced. This leads to the concaving of the water surface inside a small tube.

The answer is: b) solutes move out of the cell
Explanation:
1. cell membranes are partialy permeable, only allowing passage to some certain molecules.
2. diffusion is the movement of molecules across partially permeable membrane down concentration gradient.
3. the molecules are too big to pass through partially permeable membrane. the concentration of the molecule might be higher in the cell than in the solution/surroundings.
