The bag is more concentrated in starch than the beaker. This is because the bag contains a solution of starch and water, while the beaker contains only water.
The starch molecules are unable to pass through the plastic bag, so they remain concentrated in the bag. The water molecules, however, are able to pass through the bag, so they diffuse into the beaker, making the solution in the beaker less concentrated in starch.
If you were to leave the bag and beaker for a long enough period of time, all of the starch molecules would eventually diffuse into the beaker, and the concentration of starch in both the bag and beaker would be the same. However, in practice, this would take a very long time, as the rate of diffusion is relatively slow.

B. Mitosis produces haploid cells, and meiosis produces diploid cells
C. Chromatids are formed only during the process of meiosis
D. Mitosis has an anaphase I and II, but meiosis only has anaphase I
Meiosis produces four cells, but mitosis produces two cells
water
iodine
air
calcium
Among these, it is water which is a compound.
A compound is a substance which is made up of two or more different elements. Apart from this, the different elements in a compound are bound by a chemical bond in a fixed proportion.Water is a compound which is made up of two different elements which are hydrogen and oxygen. The chemical formula of water is H2O. Also, the proportion of hydrogen to oxygen in water is definite which is 2:1. Among other options, iodine and calcium are elements. As far as air is concerned, it is a mixture of various gases not a compound. So, correct option is water.
The correct answer is option d. The isolated plots are more vulnerable to edge effects.
Land builders and ecologists are imparting special guidelines for saving the land of 20 hectares of herbal habitat. Both have a special technique for growing the land, the land developer indicates to divide the land into twenty-one-hectare regions. While the ecologist indicates that it might be higher to have one intact land. The land with remoted regions is extra susceptible to part consequences.
Edge consequences are the amendment or extrude withinside the shape of the network that affords at the brink of the 2 or extra than habitats. Areas with small habitat fragments display excessive part consequences.
Ecology is the have a look at the relationships among dwelling organisms, together with humans, and their bodily environment. Ecology considers organisms on the individual, population, community, ecosystems, and biosphere level.
Hence concluding that isolated plots are more vulnerable to edge effects is the correct answer.

Answer:
The correct answer is option D.
Explanation:
Land developers and ecologists are providing different suggestions for saving the land of 20 hectares of natural habitat. Both have a different approach for developing the land, the land developer suggests to divide the land to 20 one hectare areas. While the ecologist suggests that it would be better to have one intact land. The land with isolated areas is more vulnerable to edge effects.
Edge effects are the modification or change in the structure of the community that presents at the edge of the two or more than two habitats. Areas with small habitat fragments show high edge effects.
Thus, the correct answer is option D.
