Gwar [14]
Answer:
igneous rock CAN become sedimentary rock through a process called ROCK CYCLE.
Explanation:
Rocks can be defined as solid structures of minerals that are formed naturally over a period of time. They are grouped into three main types which includes the following:
- igneous rock
- sedimentary rocks and
- metamorphic rocks.
Rocks are capable of transforming from one type to another through a process known as rock cycle. There are two forces that brings about this process which includes:
- The internal force : this is the Earth’s internal heat engine, which moves material around in the core and the mantle and leads to slow but significant changes within the crust.
- The external force: this is the the hydrological cycle, which is the movement of water, ice, and air at the surface, and is powered by the sun.
Molten magma cools to form either extrusive igneous rock or intrusive igneous rock. With time they undergo weathering, eroded, transported, and then deposited as sediments which are being compressed and cemented into SEDIMENTARY ROCKS. Again through the above mentioned forces, different kinds of rocks are either uplifted, to be re-eroded, or buried deeper within the crust where they are heated up, squeezed, and changed into METAMORPHIC ROCK.
Therefore the material in this sedimentary rock found in Rhombus planet used to be in igneous rock deep in Rhombus's interior due to continuous rock cycling on the planet. I hope this helps

andrezito [222]

The most significant limitation to the clinical utility of anthracycline antineoplastic medicines, which include doxorubicin (adriamycin), daunorubicin, or epirubicin, is the danger of cardiotoxicity.

  • Nevertheless, these substances continue to rank among the most popular anticancer medications.
  • Although the oxidative stress-based concept involving intramyocardial formation of reactive oxygen species (ROS) has acquired the most respect, the molecular etiology of anthracycline cardiotoxicity is still quite debatable.
  • Through redox cycling of both their aglycones and anthracycline-iron complexes, anthracyclines may facilitate the generation of ROS.
  • Given the remarkable cardioprotective efficacy of dexrazoxane, this suggested mechanism has gained a lot of traction (ICRF-187).

What is Influenza?

  • It affects the lungs, nose, and throat.
  • High-risk groups include young children, elderly individuals, pregnant women, persons with chronic illnesses, and those with weakened immune systems.
  • Fever, chills, muscle pains, cough, congestion, runny nose, headaches, and exhaustion are some of the symptoms.
  • Rest and fluids are the main treatments for the flu because they allow the body to fight the illness on its own.
  • Anti-inflammatory painkillers sold over-the-counter may aid with symptoms. An yearly flu shot can lessen complications and aid in prevention.
