Answer:
The correct answer is option d, that is, mimicry.
Explanation:
Mimicry in evolutionary biology refers to an evolved similarity between the organism and another organism of other species. The phenomenon may take place between the individuals of a similar species or between the individuals of distinct species. The main objective of mimicry is to safeguard the species from predators, resulting in an antipredator adaptation.
The evolution of mimicry takes place when the predator witnesses a similarity between the model and the mimic and as a consequence modifies its behavior in a manner, which offers a selective benefit to the mimic.
Answer:
The correct answer is option 3. a nucleus.
Explanation:
The first genetic material present in the early organisms were RNA which was present in the microscopic organisms back then 3.5 billion years ago which means it is normal to have RNA in such microfossils chemical analysis.
Since, the nucleus was not present in early life forms of prokaryotes like bacteria. so, it is unusual to find nucleus in the fossils of stromatolite rocks.
Thus, option III is the correct answer.
Answer:
Continental drift
Explanation:
Alfred Wagener told about continental drift. He said that continents were a single land mass called Pangaea. They were separated and relocated in the form of different continents. The drifting happens due to the movement of tectonic plates above the magma. As a result, the land mass was broken down into different landforms. These broken parts were carried slowly and form the continents. The continents are now also moving slowly
