What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 10x and an ocular lens power of 5x? 5x 15x 500x 50x

50x

Which of the following processes releases energy to be used by a cell? A phosphate group is added to ATP to form ADP. A phosphate group is removed from ADP to form ATP. A phosphate group is added to ADP to form ATP. A phosphate group is removed from ATP to form ADP.

A phosphate group is removed from ATP to form ADP.

Electricity is added to recharge a battery. What is added to ADP to form ATP? A second ribose group A third phosphate group A third ribose group A second phosphate group

A third phosphate group

During the process of cellular respiration, energy stored in glucose molecules is used to form oxygen molecules NAD+ ATP carbohydrates

ATP

Starch and ATP can both be described as molecules that store energy. How do starch and ATP store and supply energy? ATP is used for immediate energy and short-term storage, while starch molecules are stable and can be stored for a long time. ATP is used for immediate energy and long-term storage, while starch molecules are unstable and can be stored for a short amount of time. Starch and ATP are both stable and store long-term energy. Starch and ATP are both unstable and store short-term energy.

ATP is used for immediate energy and short-term storage, while starch molecules are stable and can be stored for a long time.

Describe three properties of mitochondria and chloroplasts that support the endosymbiotic theory. Be sure to explain your answer. add more to ex

Both the mitochondria and the prokaryotic cells have its own genetic material, in fact, the mitochondria has its own DNA (mtDNA) different from the nucleus.This mtDNA undergoes transcription just like prokaryotic DNA to make mRNA and eventually functional proteins.

What would be the best microscope to view living single-celled organisms in a sample of pond water? Transmission electron microscope Scanning electron microscope Compound light microscope Dissecting microscope

Compound light microscope

What stage of cellular respiration does not involve any carbon-based compounds as a reactant or product? Electron transport chain Krebs cycle Glycolysis Fermentation

Electron transport chain

What is produced when a yeast cell undergoes fermentation? Ethyl alcohol Pyruvate Oxygen gas Lactic acid

Ethyl alcohol

What stage of cellular respiration is anaerobic? Glycolysis Calvin cycle Electron transport chain Krebs cycle

Glycolysis

Where does the Krebs cycle occur? Cytoplasm Mitochondrion Cell membrane Nucleus

Mitochondrion

NOT ATP

Which is a difference between a compound light microscope and a transmission electron microscope? A) The compound light microscope can only view specimens in black and white, while the transmission electron microscope has color. B) The compound light microscope can view living things, but the transmission electron cannot. C) The compound light microscope examines the surface of a cell, and the transmission electron microscope examines internal parts of the cell. D) The transmission electron microscope is used for dissections, while the compound light microscope is not.

NOT C

What stage of cellular respiration produces the most ATP? Electron transport chain Glycolysis Krebs cycle Fermentation

NOT Krebs cycle

which of the following releases energy? A)Nutrients entering a cell through the cell membrane B)Removing a phosphate group from an ATP molecule C)Building sugar or starch molecules for long-term energy storage D)Adding an additional phosphate group to an ADP molecule

NOT Nutrients entering a cell through the cell membrane

The total magnification of a specimen viewed under a compound light microscope is determined by the power of the objective lens added to the power of the ocular lens the magnification power of the ocular lenses used the power of the objective lens multiplied by the power of the ocular lens the magnification power of the objective lenses used

NOT the magnification power of the objective lenses used

What substances are used up as the reactants in cellular respiration? O2 and H2O O2 and C6H12O6 CO2 and C6H12O6 CO2 and H2O

O2 and C6H12O6

Describe Professor Kwang Jeon's observations of the amoebas and bacteria and explain how this relates to the endosymbiotic theory. add more to ex

One primary example of endosymbiosis is the presence of plastids in plants and the presence of mitochondria in animal cells. These represent the prokaryotic organisms that were engulfed by the prototypic eukaryotic cell in the past.

On which part of the compound light microscope are specimens placed for viewing? Part F Part E Part D Part C

Part E

Which part of the compound light microscope provides the light source? Part A Part B Part E Part F

Part F

What molecules can be used for long-term energy storage? ADP and fat Starch and fat ADP and ATP Starch and ATP

Starch and fat

Which is a difference between a compound light microscope and a transmission electron microscope? The compound light microscope can only view specimens in black and white, while the transmission electron microscope has color. The compound light microscope can view living things, but the transmission electron cannot. The compound light microscope examines the surface of a cell, and the transmission electron microscope examines internal parts of the cell. The transmission electron microscope is used for dissections, while the compound light microscope is not.

The compound light microscope can view living things, but the transmission electron cannot.

Explain the endosymbiotic theory of the origin of eukaryotic cells in your own words. add more to ex

The endosymbiotic theory is the theory that concerns the origin of eukaryotic cells. It says that a prototypic nucleated eukaryotic cell obtained both the mitochondria and the chloroplast from engulfing prokaryotes capable of oxidative phosphorylation and photosynthesis respectively. This prototypic eukaryotic cell then evolved to become higher order beings.

What is the best microscope to get a detailed view of the parts inside of a preserved plant cell? Transmission electron microscope Scanning electron microscope Compound light microscope Dissecting microscope

Transmission electron microscope

An advantage of light microscopes compared to electron microscopes is that light microscopes..... a)allow you to view the surface of cells in greater detail than electron microscopes b) have a higher magnification capability because they use natural light c) allow you to view living cells, while electron microscopes do not d) have a greater resolution available because they use white light

allow you to view living cells, while electron microscopes do not
