The statements that are true of heterogeneous mixtures are: they settle out and the proportions of solute to solvent may vary. The correct answer is option A. 1 and 2. Heterogeneous mixtures are considered mixtures wherein the components are not uniform and still retain their properties. Characteristics of heterogeneous mixtures are: the ratio of solute and solvent is not equal, the substances can be separated physically and they still retain their properties even if mixed with another substance.

Why are scientists concerned about the use of the Bt toxin which is used to kill insects in genetic engineering
xxMikexx [17]

<span>The toxin Bt (endotoxin CrylA (b)) Bacillus thuringiensis  that is a normal inhabitant of the soil, showed himself as a natural insecticide used by farmers engaged in organic farming. In contrast to the Bt-toxin produced by bacteria, genetic engineers included it pesticide in every cell of the seed, and therefore distributed throughout the adult plant, the products from which then are consumed by man. </span>That's why scientists are concerned that after the use of a BT toxin products people get antibiotic resistance and resistance to bt.

A land developer and several ecologists are discussing how a parcel of private land should be developed with housing while savin
FromTheMoon [43]

Options for the question have not been provided. They are as follows:

A) The single intact parcel would have a smaller amount of edge than the 20 separate parcels.

B) The isolated hectare plots increase the ability of individuals to disperse from one habitat to another.

C) The separate 1-hectare plots are less vulnerable to edge effects.

D) The large plot will create more inbreeding in many species.

Answer:

A) The single intact parcel would have a smaller amount of edge than the 20 separate parcels.

Explanation:

In the given case, 20 hectares of land has been allocated to natural habitat. This means that natural flora and fauna will flourish here without any human interference. In this situation it is better to have an intact 20 hectares area at one side of the land, rather than having 20 separately spread out 1 hectare areas. This is because having one large piece of land at one side will reduce the edge effect.

Edges occur where two different habitats meet. While edges can be beneficial when it comes to natural habitats because the boundary habitat increases overall biodiversity, it can be detrimental when the edges are due to human settlements. It will be difficult to avoid human interference as the natural habitats are scattered among human settlements. Each individual plot will also get less area due to which it will be difficult for all the species to accommodate comfortably. Many animals can venture out in search of food which can be dangerous to both animals and humans. It is better to have a big separate land at one corner so that everyone can survive peacefully.
