What causes metamorphic rocks to form from existing rocks?

Biology
1 answer:
Marrrta [24]3 years ago
3 0

The rocks formed by the modification of other preexisting rocks in the interior of the Earth through a process called <em>metamorphism</em>. Through heat, pressure and / or chemically active fluids, the transformation of rocks undergoing structural and mineralogical adjustments takes place. The agents of metamorphism make possible that igneous rocks, sedimentary rocks or other metamorphic rocks, when subjected to pressures ranging from less than 1,000 to up to 16,000 bar, at temperatures ranging from 200 to 1,000 ° C, and / or an active fluid, cause changes in the composition of the same, providing new substances to them. The rock that is generated will depend on the composition and texture of the original rock, the time it was subjected to the effects of the so-called metamorphic process, as well as the agents of the same metamorphism. The precursor of a metamorphic rock is called protolite.

AVprozaik [17]

Answer:

CO2 levels will dramatically increase as well as food level supply will decrease. Oxygen levels will decrease too.

Explanation:

 Plants take in CO2 and produce Oxygen. Without plants, they can't take in CO2, and it is a necessity for them to take it in. Plants would die. Food supply would decrease because plants produce glucose during photosynthesis. Glucose is a kind of natural sugar that will be lost. Plants produce fruits or vegetables, so if there are no plants then no food.

Hope this helps!

chambers A and B are placed next to each other but are separated by a film permeable to both glucose and fructose. chambers A co
Molodets [167]

Answer:

2.glucose move into chamber B faster than fructose

Explanation:  

  • Facilitated diffusion: refers to the transport of hydrophilic molecules that are not able to freely cross the membrane. Channel protein and many carrier proteins are in charge of this <u>passive transport</u>. If uncharged molecules need to be carried <u>this process depends on concentration gradients</u> and molecules are transported from a higher concentration side to a lower concentration side. If ions need to be transported this process depends on an electrochemical gradient. The glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.  Facilitated diffusion is a passive transport process because the cell does not need any energy to make it happen.  

The exposed scenario is an example of facilitated diffusion, a process that occurs in favor of the concentration gradient, and which rate depends on the concentration of molecules in each side of the membrane, in this case, glucose and fructose, among other factors that might also influence the diffusion rate. So, as the concentration of glucose is higher in chamber A (80%), and lower in chamber B (20%), in comparison with fructose, the first one will diffuse faster than fructose. The difference in concentration between both chambers is sharper in glucose, so its transport is faster than the fructose transport, which will also diffuse but at a lower rate.

The brain's ability to restructure its neural networks to maximize functioning after an injury is known as
igor_vitrenko [27]
This capacity is known as Neuroplasticity. Neuroplasticity is the change in neural pathways and neurotransmitters that happens because of specific variables, similar to conduct, condition, or neural procedures. Amid such changes, the cerebrum participates in synaptic pruning, erasing the neural associations that are never again fundamental or helpful, and reinforcing the vital ones.
