Answer:
Diffusion is the process in which molecules and ions move from a region of high concentration to low concentration. Its also how cells transport waste out of the cell and nutrients into it hence being very crucial. Diffusion also occurs without the expenditure of extra energy using a procedure known as passive transport. (Osmosis is a form of diffusion but deals with water exclusively).
Examples of where diffusion is important;
In the intestines - Digested food molecules such as amino acids and glucose move down the concentration gradient from the intestine into the bloodstream. Wastes such as carbon dioxide or urea travel via diffusion from the body's cells to the bloodstream.
Osmosis plays a major role in living organisms. It aids in the transportation of nutrients from cells to cells and also helps to remove the waste's metabolic products from the cell. The purification of blood in the kidneys is also dependent on the process of osmosis.
The question lacks the multiple options. The options are as follows:
A. After 1 hour of moderate-intensity exercise (60% to 85% VO2 max), when blood glucose levels dwindle
B. After 1 to 3 hours of continuous moderate-intensity exercise (60% to 85% VO2 max), when glycogen becomes depleted
C. After 5 to 6 hours of continuous low-intensity (50% to 60% VO2 max), when blood glucose levels dwindle
D. After 30 minutes of continuous high-intensity (70% to 90% VO2 max), when glycogen becomes depleted
Answer:
Option (B).
Explanation:
Glucose is the monosaccharide and the single momoneric unit and when repeated again and again can leads to the formation of polymer. The glucose acts as the primary source of the energy.
The glucose is breakdown to form the ATP. The glucose is continuously used in the exercises. If the glucose is not taken, the individual be only able to perform the moderate exercise only for 1-3 hours. The individual feels fatigue and needs rest if glucose consumption is decreases in the body.
Thus, the correct answer is option (B).
A. theory because it is an explanation that is supported by extensive observations, experimentation, and reasoning.
Explanation:
Evolution can best be described as a theory because it is an explanation that is widely supported by extensive observations, experimentation and reasoning.
Theories are formulated after careful observation into a particular phenomenon.
- Most theories provides a vivid explanation into an observed event or process.
- The theory of evolution is one of such theories that suggests that an organism changes in order to adapt to its environment.
- Some of the key figures who contributed to the study of evolution are J. B Lamarck, Charles Darwin, Williams Smith e.t.c

The reason why people might worry about introducing new species in Albany is the same reason people might be worried to introduce a new species everywhere: it can replace the local species, thus it would be a thread to the biodiversity on Earth.
For example, seeds could fly away from the roof and the plant would start growing on the field nearby.
