Answer:The correct answer is letter A.
Explanation: he is right
Your teacher gives you an unknown protist to classify that is currently inactive. The protist appears to have long lash-like
appendages protruding from its cell surface. Which kind of locomotion can we expect from this protist? (1 point)
The appendages of this protist will move in a dragging motion that actively pulls the protist forward.
O The appendages of this protist will move in a sweeping motion like oars to actively propel the protist forward.
The appendages of this protist will move back and forth like a wagging tail to actively propel the protist
forward
O The appendages of this protist are not functional, and the protist moves passively via environmental forces.
Answer:
Option (A)
Explanation:
The Precambrian represents the time period, right from the beginning of the earth to about 540 million years back. It is divided into 3 parts, namely the Hadean, the Archean and the Proterozoic. Throughout this geological time, vast changes have taken place on earth. The first life forms of about 3.8 billion years old, that existed on earth were the simple unicellular organisms, whose traces were only found at some particular places. These organisms were very small and are comprised of soft bodies, so they were affected by the earth's dynamic processes. The organisms in order to get fossilized must contain hard parts. Due to the presence of soft bodies, the organisms were not fossilized and so it took a long time to demarcate that the late Precambrian organisms were animal-like life.
hence, the correct answer is option (A).
