Applying ice to a fire victim leads to tissue hypoxia and necrosis because it will change the skin's temperature too fast and may cause frostbite. The burn could have had removed a layer of skin, leaving the fragile tissue exposed which will be more sensitive to the ice.
Skeletal and cardiac muscles are known as striated muscles, because the filaments of actin and myosin that power their contraction are organized into repeating arrays, called sarcomeres, that have a striated microscopic appearance.
Answer:
C
Explanation:
Cells are a basic unit of life and that without cells you don't exist as a living being. Also, all the other answers have a flaw in them like in question A... not all cells are the same size. For question B and D... not all cells have the same, parts or organelles since for plants they have chloroplast while animals don't. Eukaryotes have membran- bound organelles and a nucleus while... a Prokaryote doesn't etc...

abundance of organisms and the interactions that determine distribution

animals that Haeckel recognized but microscopic organisms such as Bacteria, Archaea and protozoa, as well.</span>
Answer: 0.83m/s^2
Explanation:
Acceleration is the rate of change in speed in one second. Its standard unit is metres per second square (m/s^2)
Recall that at rest, the speed of train (V:) = 0
Final speed of train (V) = 25 m/s
Time taken (T) = 30.0 seconds
Magnitude of Acceleration = (Final speed V - resting speed V:) / Time taken
Acceleration = (25 - 0) / 30
= 25m/s / 30s
= 0.83 m/s^2
Thus, the magnitude of acceleration with the train moves with is 0.83 metres per seconds square
