Answer:
A. Early signs of life on earth
Explanation:
The Hadean, before the Archean, is the first geologic eon of Earth. It began with the formation of the Earth about 4600 million years ago and ended 4,000 million years ago. The planet had just formed and was still very hot due to high volcanism, a partially molten surface. Some geologists labels the period before the earliest-known rocks on Earth. At the end of it much cooler surface temperature and the formation of solid rock enabled to flaurish the life.
The answer is A.
Prokaryotic organisms are simpler than eukaryotic organisms are are single-celled. They do not contain the genetic information to form complex, specialized structures as eukaryotes do, so they cannot form multi-cellular bodies. The remaining options apply to both prokaryotes and eukaryotes.
Answer:
The correct answer will be-ventral ramus
Explanation:
Rectus abdominis is a skeletal muscle found in the front part of the body which begins from the sternum and ends at the pubic zone.
Rectus abdominis is also known as "Abs" which viewed externally appears to be six, eight or ten in number.
These muscles are innervated by the thoracoabdominal nerves which carry and transmit signals to CNS and to the muscles back. The main spinal nerve which controls the movement of Abs is known as the "ventral ramus".
Thus, ventral ramus is the correct answer.
