A. Tardigrades, small animals, can survive exposure to the near-vacuum of space

B. Life was present on Earth soon after the end of the heavy bombardment.

C. Life is currently present in extreme environments like deep ocean volcanic vents

D. All organisms on Earth use DNA as their genetic material.

2. The modern organisms that appear to be most like the earliest life on Earth are (A)

A. simple animals like worms.

B. microbes living near undersea volcanic vents.

C. green algae.

Answer 1

Question 1.

SINCE every organism carries their genetic information on DNA , And formation of DNA is simple process which has occurred simultaneously in the beginning of evolution of life on earth . therefore it is the perfect evidence which suggest that life arises relatively easier .

​Quesion 2.

Green algea and microbes living near undersea volcanic vents are primitive , they don't have complex structural organization (tissue level)

For modern

$Cell\rightarrow tissue\rightarrow Tissue System$

Thus simple anmals like worms are modern organism
