Water is denser than isopropanol, so the water layer will always be below the isopropanol layer if they are both in the same con

tainer. What does this tell you about the make-up of the pigments for each specimen?

Answer:

One is polar and the other is non-polar.

Explanation:

The makeup of both water and isopropanol is different from each other due to their polar nature. Water is a polar substance means that it makes poles i.e. positive or negative while on the other hand, isopropanol is non-polar substance so due to this reason water and isopropanol make different layers. If both are polar or nonpolar substances so they will able to mix with each other.

What are the features of Oligonucleotide Therapies Discovery?
NikAS [45]

Explanation:

For antisense gene therapy, chemically engineered oligonucleotides complementary to specific mRNA are inserted into the cells which stop the translation of the specific protein. Similarly, the antisense drug contains the vital molecule—“the noncoding mRNA”—which blocks the translation of a specific protein.

It causes eutrophication which means that the algae have too much nutrients and take over the pond, use the oxygen so there is not enough left for marine life, which die as a result.

Plant transgenic technology is important for the introduction of genes that convey traits related to environmental stresses and
Gekata [30.6K]

The options of the given question are:

method for DNA delivery

gene construct

efficient selection strategy

tissue culture system

Answer: Tissue culture system.

Explanation:

The role of tissue culture system is not much in case of the transgenic plant. The method of DNA delivery, efficient selection strategy and gene construct are involved in the plant transformation.

But plant tissue culture is not directly involved in the plant transformation. The plant tissue culture is the collection of the techniques which is used to maintain the growth of the plant cells and so it does not plays any important role in plant transformation.

The plant transformation is the introduction of the desired characters into the plant and then the growth of transformed plant takes place in the culture medium. This has no role in the plant transformation or has less role.

Which one of the following statements about the troposphere is
Dvinal [7]

Answer:

B. The tropospheric gases move becuase of convection currents.

Explanation:

The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe. In the Northern and Southern hemispheres, air rises along the equator and subpolar ( latitude about 50 to about 70 north and south ) climatic regions and sinks in the polar and subtropical regions. Air is deflected by the Earth's rotation as it moves between the poles and equator, creating belts of surface winds moving from east to west ( easterly winds ) in tropical and polar regions, the winds moving from west to east ( westerly winds ) in the middle latitudes. This global circulation is disrupted by the circular wind patterns of migrating high and low air pressure areas, plus locally abrupt changes in wind speed and direction known as turbulence.
