<span>Every living organism begins life as a single cell. Unicellular organisms may stay as one cell but they grow too. Multicellular organisms add more and more cells to form more tissues and organs as they grow. </span>
Adenosine triphosphate or ATP is a compound that stores and provides the energy required to perform a variety of biochemical processes in living beings.
After being consumed, it losses one or two of its phosphates and becomes adenosine diphosphate (ADP) or adenosine monophosphate (AMP).
It can also act as a coenzyme and be a precursor to DNA and ARN because it is a nucleic acid.
Each molecule of ATP is a nucleoside triphosphate, formed by an adenine (a nitrogenous base), a ribose (a sugar), and triphosphate.
This means the correct answer is A) nucleic acid
A compound consists of two or more elements.
In 1970 only about 20% of Psychology majors were women. In recent polls women now make up just over 70% of psychology majors. I would say the answer is False.
The answer is hard tissue.
Usually, hard tissue, such as bones and teeth or exoskeleton is much more preserved than soft tissue (organs, skin, etc.). Fossils become fossils by a process of mineralization. Hard tissues are more mineralized during life than organs. So it is no surprise that hard tissues take part in the process of mineralization and is preserved in fossils, unlike soft tissues.
