Why is it difficult to evaporate seawater?
Alika [10]

Answer: Different liquids will evaporate differently depending on the force of attraction between the molecules of the liquid. The weaker the force of attraction the higher the rate of evaporation and vice versa.

In Sea water the water molecules are attracted to the salt ions and thus it requires more energy to evaporate.

bekas [8.4K]

Answer:

We could feed them with another type of food free of silver salts.

Explanation:

When talking about a phenocopy, we are referring to individuals who genotypically should be expressing a determined phenotype, but due to environmental influence, they express another phenotype. This is a non-inheritable phenotype, so it is not considered a mutation.

If we grow thy flies feeding them another type of food that does not include silver salts, and let them mate and reproduce, they will express the real phenotype, because they will not be influenced by the food. In the following generation, there will be dark individuals carrying the dominant allele, and yellow individuals, with the recessive genotype.

irinina [24]

When faced with a complex engineering problem, the best strategy usually involves( A ) Breaking the problem down into smaller problems and solving them individually.

Explanation:

Th first step of solving a complex problem involves problem identification-it means what exactly is the problem then we try to determine the possible sub-groups in which the problem can be further divided  and then numbering the sub groups.

The process of sub-grouping means that we are sub dividing the problems and then working upon the problem that needs the attention first and then according solving the other sub categories of the problem.

This method helps in breaking the complex problem into a series of small task that can be easily solved in a sequential manner .Thus the complexity of the problem gets reduced when it is divided into a number of small problems.
