Answer:
Number 3 is the answer most likely. This is because both hemispheres are an equal distance from the equator.
Answer:
1. Yes
2. No
3. Yes
Explanation:
Yes, the elimination of the animal based foods decreases and reduce chronic diseases in many developed countries such as US and England etc. but meat is also very necessary for animal diet due to the presence of high protein content.
No, USDA does not promote the intake of an animal-based diet. this agency promote the intake of nutritious food in a limited amount so it does not cause any disease. They recommend the eating of Grains, Fruits, Protein, Foods, Vegetables and Dairy products in a limited amount.
Yes, the main cause of obesity in Americans is due to two reasons, first cause is the intake of meat in large amount and second cause is the decline in physical activity.
The success of the patients was due to combined effect of increased amount of fruits/vegetables and plants and the elimination of meats. By using these two element the patient will quickly recovered.
Vaccines are a boon in eradicating various lethal diseases and increase the immunity of the people. The development of vaccines started with the understanding the cell itself, various pathways that regulate its fate. The immunology, a branch of biological science, gave the idea of the working of the defense or the immune system of the body, and of the various specia cells that function for it. This led us to the discovery of antibodies and antigens. Vaciines are artificial means of injecting antigens into the body to generate antibodies beforehand, so that the immune system remembers producing it at the time disease causing agent strikes us.
Thus, we can summarise that STEM research or core science research has led to innovations that have shaped our lives and lifestyle to contribute to an overall good social health.
Answer: Water will leave the cell and the cell will shrink.
Explanation:
Osmosis is the net movement of water from an area of low to high concentration of solutes through a semipermeable membrane. If none of the compartments contains solutes, then the water moves in either direction between the compartments. <u>However, if we add a solute to one of the compartments, this will affect the probability of water molecules leaving that compartment and moving into the other compartment.</u> The ability of water to move into or out of a cell is called tonicity. The tonicity of a solution is related to its osmolarity, which is the total concentration of all the solutes in the solution. A solution with low osmolarity has few solute particles per liter of solution, whereas a solution with high osmolarity has many solute particles per liter of solution. When two solutions with different osmolarities are separated by a membrane permeable to water but not permeable to solutes, water diffuses from the side with lower osmolarity to the side with higher osmolarity. So, solutions can be:
- <u>Hypotonic</u>: The extracellular fluid has a lower osmolarity than the fluid inside the cell, it is hypotonic with respect to the cell, and the net flow of water will be into the cell.
- <u>Hypertonic</u>: The extracellular fluid has a higher osmolarity than the cytoplasm of the cell, it is hypertonic with respect to the cell and water will flow out of the cell.
- <u>Isotonic</u>: The extracellular fluid and the cell have the same osmolarity so there is no net movement of water.
If a cell is placed in a hypertonic solution, water will leave the cell and the cell will shrink due to the difference in pressure and may even die from dehydration.
