They are called heterotrophs
Organisms that DO use the sun for energy are called autotrophs
Hint: Auto- Automatic- Autotroph (It automatically happens)
Hope this helps you :)
Answer:Sand and other particles are buried, compacted, and cemented together.
Explanation:
The major cause of vascular dementia is known as narrowing and blockage of the small blood vessels inside the brain.
Sickle-cell disease is a single gene disorder where by the mutations in the beta-globin gene leads to formation of deformed haemoglobin molecules called haemoglobin S.
The signs and symptoms found in sickle-cell disease is the sickling of the red blood cells which leads to:
- premature break down of red cells,
- anaemia
- yellowing of eyes and skin (signs of jaundice)
- Painful episodes can occur when sickled red blood cells, which are stiff and inflexible, get stuck in small blood vessels.
Vascular dementia is a type of dementia that leads to loss of memory.
Vascular dementia occurs in individuals with sickle-cell disease due to narrowing and blockage of the small blood vessels inside the brain by the sickled cells.

The radiometric dating of an igneous rock provides the relative age of the rock
What is radiometric dating ?
Radiometric dating, radio dating, or radioisotope dating, is a technique used to date materials such as rocks and carbon that are selectively incorporated when minute amounts of radioactive contaminants are formed. This method compares the abundance of a naturally occurring radioisotope in a material with the abundance of its decay products formed at a known constant decay rate. First published by Bertram Boltwood in 1907, the use of radiometric dating is now the primary source of information regarding the absolute age of rocks and other geological features, including the age of fossilized life forms and the age of the Earth itself. is the source. Used to date his one wide range of natural and man-made materials.
