Probability: The chance of something happening and the likelihood of a particular event happening.
Answer:
To observe the cheek cell,
-
Take a tooth pick use its blunt side to scrap inside the mouth.
- You will see some deposition on the blunt side of tooth pick, make a smear on the clean slide in the center using that tooth pick.
- Add a drop of methylene blue solution and place a coverslip, make sure that bubbles are avoided i.e. coverslip should be placed in the inclined manner.
- Remove the excess solution and observe it under the microscope first under 4X and then under 10X.
Observation:
- The cells observed are squamous epithelial cells. The small blue dots seen inside will be the bacteria from our teeth and mouth.
an abnormal growth of scar tissue that is thick and out of proportion is called a keloid
Answer:
1. Photosynthesis
2.carbon dioxide
3. fossil fuel
4.cellular respiration
Explanation:
Photosynthesis is the important function takes place mostly in green plants which converts inorganic compounds, water, carbon dioxide to the glucose or organic compound in presence of light energy. It is an important reaction that is required for energy and for food for almost every organism.
Carbon dioxide is the carbon source for the plants to produce glucose or simple sugars with help of water and light energy.
Fossil fuels are formed by the process of decomposition of organic compound and organism of the prehistoric organism which is a carbon containing energy source.
Breaking down or catabolism of glucose in order to produce energy in the form of the ATP is called cellular respiration which is essential for cell to perform cellular functions.
There is a limit to how much Euglena and other single-celled organisms can grow because single cell organisms tend to not capable to do complex activities.
Humans for example has billions of cells within our body that allow us to grow and do complex activities
hope this helps
