Answer:
In 1._
eon, there is no such thing as life. The new planet was bombarded by 2._
and volcanic eruption as it was too hot to contain by living creatures. Until the later part of this
eon, hydrologic cycle was continuously formed that started the formation of 3._
Regardless of
what the Earth looks like, scientist believe that the first life sprouts 4._
ago.
The 5._
theory wherein it states that living organisms was formed by the reaction of chemicals
such as 6._
methane, carbon, 7._
nitrogen, phosphate and 8._
that is
submerge in the vast ocean to the energy produced by lightning that leads to the growth and reproduction of
9._ ,proteins, enzymes and DNA which are the backbones of all living organism.
There are two classifications of living organism. 10._
is an organism that makes their own
food and generates their own energy in a process called photosynthesis; on the other hand, 11._ are dependent consumer.
The scientist theorized that the first living organism is 12._
that can be
found in the deep of the oceans, wherein there is an abundant chemicals and energy coming from the vents
of volcanic activity in the oceanic crust and free from harmful heat coming from the rays of 13._
14._
(LUCA) is not considered to be the first life form, but it's the last far back
that can be traced. Unlike other organism, LUCA do not have the characteristics, because scientists do not
know what it really looks like, but because of three domains like 15._,
16._,
and 17._,
that has shared the same gene across these species and domains it must be inherited from the
common ancestor which is called LUCA. Different eons and eras passed and different life forms lives, extinct
and evolve through time based on how they function based on their structure. 18.__
have the same
structure as they are from the same ancestor but differ from their function like arms of monkey and the fins
of dolphin, on the other hand, 19._
have different structure as it was from different ancestor, but
similar in function like the wings of bird and insects. Therefore, organic matter such human being is theorized
that came from 20._
matter that combined together and grow the reproduced through time.
PAHELP PO, THANKYOUUU!
