Between the vertebrae are small spaces known as intervertebral canals that allow spinal nerves to exit the spinal cord and connect to the various regions of the body. There are 5 major regions of the spine: Cervical: The 7 vertebrae in the neck form the cervical region of the spine.
Index fossils (also known as guide
fossils, indicator fossils or zone
fossils) are fossils used to define
and identify geologic periods (or
faunal stages).
Answer:
The valuable organic molecules produced by autotrophs serve as sources of food for the heterotroph and supply the necessary nutrients living organisms need to grow and survive.
Without these valuable organic molecules living organisms can not survive , grow and develop.
The organic molecules serve as sources of energy needed to fuel biological processes in the organisms.
Explanation:
Autotrophs are group of organisms that can produce their own food through the process of photosynthesis where inorganic molecules are converted to organic molecules i.e they use light energy from the sun with water and carbondioxide to produce carbohydrates and oxygen.
Heterotrophs or other living organisms depend on autotrophs for the supply of organic matter as food nutrients and sources of energy needed for cellular or biologic processes.
During transcription, mRNA is synthesized using DNA as a template. This process usually takes place in the cell nucleus and is carried out with the help of an enzyme called RNA polymerase.
mRNA plays the role of a messenger hence the term messenger RNA or mRNA in short. Information for synthesis of a specific protein is transcribed on mRNA in the nucleus of the cell. The mRNA then leaves the nucleus and enters the cytoplasm and attaches onto a ribosome. Ribosomes are cell structures fondly called the "work bench " of the cell.
It is in the ribosomes that the information brought by mRNA is translated or decoded and used to synthesize the specific protein that was coded for.
