Matthias Jacob Schleiden was a German botanist who, with Theodor Schwann, cofounded the cell theory. In 1838 Schleiden defined the cell as the basic unit of plant structure, and a year later Schwann defined the cell as the basic unit of animal structure.
C. I believe this is correct
The answer is B.hope this helps
An immediate corollary for the special case of uniform motion is that Newtonian physics is inconsistent with his first law and is, instead, consistent with Galileo's definition of inertial motion.
Hope this helpsss!!!! :)))))
<u>Answer:</u> Both require a vacuum.
<em>The common feature of scanning electron microscope and transmission electron microscope is that they both require vacuum.
</em>
<u>Explanation:</u>
Electron microscope has <em>various advantages over light microscope</em> due to their better magnification and resolution. The transmission electron microscope and scanning electron microscope use electrons for functioning. Thus they require vacuum for their operation since the electrons will be <em>lost in the absence of vacuum.
</em>
Thus it is impossible to examine living cells under an <em>electron microscope.</em> The nature of the images formed by these microscopes is different. Transmission electron microscopes produce <em>2 D images while scanning electron microscopes produce 3D images.
