How is osmosis different from diffusion

1 answer:

7 0

Diffusion is a spontaneous process in which molecules move with their concentration gradient. For example, if you place food coloring in water, the food coloring will slowly diffuse through the water until the entire solution has been balanced.

Osmosis is specifically the movement of <em>water</em> through a semipermeable membrane - meaning a membrane that can let some substances in but keep others out - and, similar to diffusion, it moves with its concentration gradient. For example, if you place a glucose solution sealed in plastic in water, water will move into the plastic to even out the concentration of glucose in the entire solution because glucose is too large to diffuse freely.

Why is scientific knowledge more reliable than other types of knowledge?

RUDIKE [14]

Answer:

D. Because science only uses facts that are proven 100% true through the use of variables.

Explanation:

All the knowledge we read is science books are not merely some observed facts but the result of a systematic scientific methodology through which facts are tested. Science only gives us that knowledge as facts which is proven 100% true through the use of variables.For example: if a scientist has studied the effect of salt stress on the growth of plants and he got the results in form of graphs which show that growth of salt treated plants in very less than normal plants. Then he needs to draw conclusion after consulting relevant previous experiments and say that salt stress hinders growth and why? with reasonable logic.

Variables are the things hat he changes like environmental conditions in previous example to see that in changed conditions plant is showing changed behavior. This way a scientist strengthens his results. Therefore, we can say that whatever knowledge we get through science is proven 100% true through the use of variables.

Economic importance of tilapia fish

dezoksy [38]

Answer:

Tilapia is one of the most productive and internationally traded food fish in the world. The production of farmed tilapia is among the fastest expanding food sectors in the world. Nile tilapia ( Oreochromis niloticus) is the most cultured freshwater species among the farmed tilapia and contributes about 71% of the world total tilapia production.

Tilapia is one of the most important farmed fish species worldwide (FAO 2018) and an important source of protein (Fitzsimmons 2000;Hai 2015). Due to its sequenced genome (Conte et al. 2017), easy reproduction, efficiency in adapting to diverse diets, high resistance to diseases and handling practices, and high tolerance of a wide variety of husbandry conditions, it is considered an ideal model in toxicological research.
