Answer:
The presence of similar <u>fossils(B)</u><u> </u> and <u>rock formations(C)</u> on several different continents supports the theory of Continental Drift.
Explanation:
Alfred Wegener observed fossils of organisms that were not supposed to have survived in the climate of where they were found. Other key findings is that he found fossils of organisms that were found in one continent and the same fossils found on another continent whose edges seem to fit together.
He also observed rock formations or stratas of mountain ranges in one continent seem to fit together with another continent.
<u>Added note:</u>
Even if Alfred Wegener had these evidences to present, his theory of Continental Drift was rejected mainly because he could not explain the mechanism of how the super continent (Pangaea) split.
Answer:
Simple cell
Explanation:
Simple cells are found in primary visual cortex and are made up of large number of receptive fields from neurons and the respond to light at specific Orientation and oriented edges. The cells were discovered by Torsten Wiesel and David Hubel in the late 1950s. The simple cells respond to stimuli with some particular orientations to objects within their receptive fields. Receptive fields comprises of sensory receptors in the sensory neurons that draw out neurosonal responses when there are stimulated
Answer:
Restriction enzymes
Explanation:
Restriction enzymes are also called 'molecular scissors' as they cleave DNA at or near specific recognition sequences known as restriction sites. These enzymes make one incision on each of the two strands of DNA and are also called restriction endonucleases.
