This question had choices. These are the missing choices.
A) Scientists made careful observations of behavioral patterns.
B) The DNA mutation rates for both species was calculated and compared.
C) Scientists made a detailed analysis of the fossilized bones of each species.
D) The enzyme activity of each species was studied to determine similarities in metabolism.
My answer:
C) Scientists made a detailed analysis of the fossilized bones of each species.
This determination is the only feasible thing to do since dinosaurs are long dead and choices A, B, and D requires the subjects to be alive.
Robert Hooke observed the thin slice of cork cells present in the plant cells. In 1665, Robert Hooke referred these empty tiny box-like cavities as cork cells.
<h3>What is Robert Hooke's Observation?</h3>
In 1665, Robert Hooke used a microscope to examine a tiny box-like empty cavities which are referred to as cork cells. He observed that the cork was made up of tiny units that looked like a honeycomb. He referred to them as cells, and he was the first to find a dead cell. This observation has a major contribution in the cell theory.
Hooke published his results under the title Micrographia, about his microscopic observations on several plant tissues. He is remembered as the coiner of the word “cell,” referring to the cavities he observed in thin slices of cork. The cork cells protect the tree from bacterial or fungal infection. It prevents water loss through the bark.
