Answer:
Flowing rivers and streams,Spring-fed bodies of water,Most open water except in tropical regions,
There are 37.2 trillion cells in the human body
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: Nervous system
Explanation:
The cerebellum of the brain is the structure of the nervous system known to control various muscles of the body that are involved in involuntary activities such as breathing.
Thus, the nervous system controls and regulates a person's breathing
Answer:
There is a great difference between light and scanning electron microscope. The source of illumination is light rays in light microscope while in scanning electron microscope electrons are the source of illumination.
The resolving and magnification power of scanning electron microscope is much greater than that of a light microscope. The magnifying power of a light microscope is 1000X and of electron microscope is 10,00,000X.
In light microscope image is seen through the eyepiece while in scanning electron microscope it is seen on a fluorescent screen. Even small specimens up to 0.1 micrometers can be seen by scanning electron microscope which is not possible to see by light microscope.
