Answer:
the sun
Explanation:
The typical lunar eclipse happens when the Sun, Earth and moon are all aligned 180 degrees apart from each other in the sky. When this happens, the Earth casts a shadow onto the moon, so the Sun should not be visible at all if you can still see the moon.
Birds and reptiles lay amniotic eggs. They consist of a shell, embryonic membranes, and the embryo.
Answer:
True
Explanation:
ATP – or Adenosine Triphosphate – is the primary energy carrier in all living organisms on earth. Microorganisms capture and store energy metabolized from food and light sources in the form of ATP.
When the cell requires energy, ATP is broken down through hydrolysis. The high energy bond is broken and a phosphoryl group is removed. The energy released from this process is used to drive various cellular processes. ATP is constantly formed and broken down as it participates in biological reactions and it is central to the health and growth of all life. Without it, cells could not transfer energy from one location to another, making it impossible for organisms to grow and reproduce.
ATP is a nucleotide that consists of three main structures: the nitrogenous base, adenine; the sugar, ribose; and a chain of three phosphate groups bound to ribose.
