Answer: b.Nutrients collected by the immune system are carried throughout the body by the integumentary system
The correct answer is: Even though the S strain had been heat-killed, it changed the R strain.
Griffith in his experiment used two strains of bacteria:
• The rough strain (R) which did not cause pneumonia, (nonvirulent)
• the smooth strain (S) which did caused pneumonia (virulent)
When Griffith heat-killed the S strain it did not caused mice to die.
But, when he gave both the heat-killed S strain and the R strain to mice, the mice developed pneumonia and died.
Griffith conclusion was that the R-strain bacteria took what he called a "transforming principle" from the heat-killed S bacteria which transformed the nonvirulent R strain.

True, air pollution is like smog in a city. It surrounds the atmosphere and causes you to breath in chemicals, the crops and plants that absorb the air as well. It's very harmful for your system and for the wildlife around.
Answer:
- The primary force driving fluid transport between the capillaries and tissues is hydrostatic pressure.
- which can be defined as the pressure of any fluid enclosed in a space. Blood hydrostatic pressure is the force exerted by the blood confined within blood vessels or heart chambers.
- The rate of exchange, In either direction, Is determined by physical factors : hydrostatic pressureb , oncotic pressure , And the physical nature of the barrier separating the blood and the interstitium of the tissue (Ex:- The permeability of the vessel wall).
