Answer:
33 vertebrae
Explanation:
The vertebral column of an adult human being is composed of 33 vertebrae, of which 24 are known as articulating or movable vertebrae, and are separated from each other by an intervertebral disc. The remaining 9 vertebrae lack the intervertebral disc and form two sets of fused structures.
Hope this helps!

Answer:
The fluid constituent of the cytoplasm is known as the cytosol, and within the cytosol various organelles are present. The first or the initial stage of cellular respiration, that is, glycolysis takes place within the cytosol of the eukaryotic cell. Glycolysis in simple terms is also known as the dissociation of sugar molecule. In the process of glycolysis, glucose gets transformed into the molecule of pyruvate.
The pyruvate, that is, the end product of glycolysis is further used in other steps of cellular respiration. The other steps of cellular respiration take place within the mitochondria.
Answer:
When selecting the proper microscope to view a sample, you should choose a simple microscope to look at a fresh lung tissue (whole organ), a compound microscope to observe the patterns of cells on a slide, and an electron microscope to study individual organelles within cells in great detail.
Explanation:
Many types of microscopes are available, they are used by researchers, medical technicians and students on a daily basis upon their need.There are different kinds of microscopes.
The simple microscope is generally considered to be the first microscope ,it provides information about biological specimens. Its magnifying power ranges between 200 and 300 times. it can easily be used to magnify a whole tissue.
With two lenses, the compound microscope offers better magnification than a simple microscope,the second lens magnifies the image of the first is high magnification, which allows users to take a close look at objects too small to be seen with the naked eye, observing pattern of cells.
Electron microscopes uses electrons rather than light for image formation, creating a magnified image, and samples are scanned in a vacuum so they must be specially prepared. An electron microscope offers a high degree of both magnification and resolution, making it useful to study cells in detail.
