There are three types of muscle, skeletal or striated, cardiac, and smooth. Muscle action can be classified as being either voluntary or involuntary. Cardiac and smooth muscles contract without conscious thought and are termed involuntary, whereas the skeletal muscles contract upon command.
Answer:
The heat of reaction -1.9 kilo Joules.
Explanation:
Volume of the hydrogen peroxide solution = 50.0 mL
Volume of the ferric nitrate solution = 10.0 mL
Total volume of the solution = 50.0 mL + 10.0 mL = 60.0 mL
Mass of the final solution = m
Density of water = density of the final solution = d = 1 g/mL
![Mass=density\times Volume](https://tex.z-dn.net/?f=Mass%3Ddensity%5Ctimes%20Volume)
![m=1 g/ml\times 60.0 ml=60.0 g](https://tex.z-dn.net/?f=m%3D1%20g%2Fml%5Ctimes%2060.0%20ml%3D60.0%20g)
Heat capacity of the mixture = c = 4.18 J/g°C
Change in temperature of the mixture = ΔT = 7.47°C
Heat absorbed by the mixture = Q
![Q=mc\Delta T](https://tex.z-dn.net/?f=Q%3Dmc%5CDelta%20T)
![Q=60.0 g\times 4.18 J/g ^oC\times 7.47 ^oC=1873.48 J=1.873 kJ\approx 1.9 kJ](https://tex.z-dn.net/?f=Q%3D60.0%20g%5Ctimes%204.18%20J%2Fg%20%5EoC%5Ctimes%207.47%20%5EoC%3D1873.48%20J%3D1.873%20kJ%5Capprox%201.9%20kJ)
Heat release due to reaction = -Q'
-Q' =Q (law of conservation of enrage)
Q'= -Q = -1.9 kJ
The heat of reaction -1.9 kilo Joules.
Answer:
conceiving a child who is a bone marrow match to a living child.
Explanation:
B.
<u>Both use kinetic energy to produce electricity</u> is a similarity between power plants that use water as an energy source and those that use wind as an energy source.
Explanation:
Kinetic energy Is the intrinsic energy that an object or substance possesses due to its motion. All power plants that use water as an energy source utilize the kinetic energy of water to produce electricity. For example, hydro-power plants use the kinetic energy of water flowing due to gravity. Tidal power plants utilize the kinetic energy of water flowing due to tidal changes and geothermal powerplants utilize the energy of steam-water ejecting underground through fissures.

Answer:
a semi-crystalline structure is formed, which holds the water molecules apart, making ice less dense than liquid water, such that it floats. This means that it insulates the water beneath, allowing organisms in the liquid water to survive. Cohesion is the tendency of molecules within a substance to ‘ stick together
