There’s proteins (muscle) lipid (fat) calcium )bones) and carbohydrates (mostly for energy)
Answer:
The options are
it was too old to be used in modern times
it was too complicated for scientists to understand
scientists found new evidence to prove it invalid
scientists discovered a shorter theory to replace it
The answer is scientists found new evidence to prove it invalid
Steady State Theory of origin of the universe has been rejected due to new findings about how the universe was formed through carefully observing it which faulted past theories. This validates the option which states that scientists found new evidence to prove it invalid.
Answer: rock melting—>crystallisation
Explanation: I am going to assume that the process must be a formal word like sedimentation, metamorphism, or crystallisation. The formal word for it is crystallisation. Metamorphic rocks are rocks that doesn’t melt even when exposed to extreme heat. This can be found under the Earth’s crust (so basically underground) near/under mountains. It is really hard to melt, but when they do melt (I’m not sure what the formal word is for this process, so I’m going to call it rock melting) the metamorphic rock turns into magma. This magma comes to the surface whenever the volcano erupts and is called lava. Whenever the lava dries up (crystallisation), it forms igneous rocks.
The carbon cycle - CO2 is fixed into biomolecules.
Answer:
Cell deterioration
Explanation:
Once the cells first come in contact, they immediately create a cell shield that is composed of weaker cells, while the rest continue their work, the problem with this, is that their is a lack of cells to do work and the weaker cells are slowly dying and creating holes for the harmful chemicals to enter, as the cells deteriorate they clot together and create a lump in a final attempt, and it ends up creating deadly weight in the lungs.
