C. it cannot be created nor destroyed only transferred
For the Data and Observation refer the image attached.
Data Analysis:
Calculate the percentage of the cell cycle spent in each stage.
Number of cells in given stage ÷ total number of cells counted × 100 = % of the cell cycle spent in this stage
Conclusion:
Be sure to answer the following reflection questions in the conclusion of your lab report:
Based on your data, what can you infer about the length of time spent in each stage of the cell cycle?
The most time is used in the cell cycle is in the interphase.
What stages were the longest and shortest? Give a brief explanation of why these stages may have that time period.
The longest phase of the cell cycle is the Interphase. Most of the total time of cell cycle is spent in the Interphase. The reason for this being is that the cell prepares itself for its division, and also in this phase, the necessary protein for the duplication of organelles occurs.
Answer:
Microtubules
Explanation:
These filament-like structures are a major component of the cytoskeleton of the cell and help is maintain asymmetrical cell shape. They are composed of tubulin molecules arranged to form a 'hollow straw' attached to the cell membrane end to end . The contraction and lengthening of these microtubules are controlled by the addition of removal these of tubulin molecules to vary its length.
Answer:
B) They release oxygen that organism use to breathe.
Explanation:
The process of this is called Photosynthesis. The plant takes in carbon dioxide and sunlight. The sun and water makes it possible for the plant to make sugars which are glucose which is the plant's food. And the byproduct of that is oxygen.
They do not have external ears like us. but they do have ear holes located directly behind their eyes. frogs ear holes are covered with thin tympanic membranes or the eardrums that protect the inner ear cavity.
