As a rule of thumb, in order to improve the reliability and accuracy of an experiment, it is best if the experiment is repeated several times. The increased number of trials ensures that the readings observed have minimal random error.
Answer:
- Human growth and functioning can be explained by the functioning of the cells.
- Cells are the fundamental units of humans.
- The functioning of the cells in the body determine human health.
Explanation:
The cell is the basic unit of life. Therefore the biochemical activities of the cell at a micro-level will definitely influence overall physiology at the macro level of an organism. For example, the production of Thyroid hormone at the molecular level by the cells in the thyroid glands will influence the metabolisms of all cells in a human being and therefore affect the organism’s overall growth and development.
A: between the hydrogen atom of one water molecule and the oxygen atom of another
The hormone ADH operates by negative feedback mechanism in that when the body's tissues lack water, it causes the nephrons to retain water to prevent the body's tissues drying out.
Answer:
Explanation:
osmosis is the movement of water molecules from the region of higher concentration to the region of lower concentration down the concentration gradient.
some of the examples are root hair cells as they absorb water molecules from the soil and are low in concentration compare to the soil. so osmosis takes place
