Answer:
A = water is an excellent solvent.
Explanation:
What is solvent:
Solvent is the that part of solution which is present in large proportion and have ability to dissolve the solute.
Explanation:
In simplest form solvent is something in which other substance get dissolve. The most widely used solvent is water, other examples are toluene, acetone, ethanol, chloroform etc.
Water is called universal solvent because of high polarity all polar substance are dissolve in it. Hydrogen is less electronegative while oxygen is more electronegative and because of difference in electronegativity hydrogen carry the partial positive charge while oxygen carry partial negative charge.
Water create electrostatic interaction with other polar molecules. The negative end of water attract the positive end of polar molecules and positive end of water attract negative end of polar substance and in this way polar substance get dissolve in it.
Example:
The minerals and nutrients in our body dissolved in water and transported through out the body.
Answer:
Continental crust. The continental crust is the layer of granitic, sedimentary and metamorphic rocks which form the continents and the areas of shallow seabed close to their shores, known as continental shelves. It is less dense than the material of the Earth's mantle and thus "floats" on top of it.
Explanation:
<span>If the genotype is PP then when crossed with pp all the offspring will be Pp and purple.
If the genotype is Pp then when crossed with pp 50% of the offspring wil be Pp (purple) and 50 % will be pp (white).
These results will allow you to see whether the purple is homozygous (PP) or heterozygous (Pp).</span>
Answer:
nucleus and we need dna so we can figure out people in our past
Explanation:
<span>C. When energy increases, particle motion INCREASES.
This is because as the energy increases, particles have more kinetic
energy which means that they vibrate faster and as such motion
increases
