Answer:
C is the correct option. Storage of carbohydrates is not a function of the skeletal system.
Explanation:
Option A is correct because the skeletal system has parts like the red bone marrow in which red blood cells and white blood cells are produced.
Option B is correct because the bones store minerals like calcium and phosphorus.
Option D is correct because the major function of the skeletal system is to provide support and protect the vital organs of the body.
The skeletal system is not involved in storing carbohydrates. Hence, all statements are true except for statement C.
The core of a star must react a temperature of 10,000,000 degree Celsius for hydrogen fusion to begin
Explanation:
A star formed from a rotating cloud which is made up with completely with helium and hydrogen. The gravitational force pulls the cloud behind to collapse inward and due to this it shrinks and later it spins more and more quickly with the outer parts.
When the core and inner part become a rough spherical clump then it becomes disk. The star life cycles follow the patterns which is based on mostly on their initial mass.
Answer:
1st law of thermodynamics- energy can not be created or destroyed
2nd law of thermodynamics- energy becomes less useable
-only ten percent of energy in the producer level can be transferred to the next level and so onto the next level
- the lost energy either becomes heat or waste
About 0.3 percent is about the safe amount of water humans may consume, the other 99 percent is in oceans, soil, icecaps, and floating in the atmosphere.
