Which of the following is not due to water’s surface tension?

The correct answer is option D, that is, ice floating on the water surface.  

The cohesive forces among the molecules of a liquid are accountable for the process called surface tension. Surface tension refers to the tension of the surface film of a liquid resulting due to the attraction of the particles in the surface layer by the bulk of the liquid that seems to reduce the surface area.  

The examples of surface tension are walking of small insects on water, floating of a needle, the surface tension of water offers the essential wall tension for the creation of bubbles with water, and surface tension is accountable for the shape of liquid droplets.  

The low density of ice makes it float at the liquid water surface, like ice cubes in a glass of water, or an iceberg. The lower density of water in its solid form is because of the way hydrogen bonds are aligned as it freezes, the water molecules are pushed further far away in comparison to the liquid water.

How easy or difficult was it to find an example of each category?

Depending on what resources you use, it can be easy or difficult to get examples of each categories

Some easy way can include searching google, wikipedia, encyclopedia.org, etc. These usually give you a broad and large amount of information that you can draw out of, and an over view that allows you to know what the paragraph would be talking about before you use it. 

Difficult ways would be searching through specific websites, such as national geographics, etc, which gives you specific details on the idea (and is more trusted then the others)

Remember too always get facts, not opinions, unless your question asks for others opinions, and to look for what researchers or well-known people within that topic says, and to not get any information from "who-knows-who-typed-it" websites, such as ask.com, etc.

After crossing over as shown below what would the sequence of genes be for each of the chromatids
SashulF [63]

The sequence of the genes will be ABCD, abCD and abCd, abcD.

Full question is attatched below.

<h3><u>Explanation:</u></h3>

The genes in the chromosomes are denoted as the sequence of genes present in a single chromatid of a particular chromosome. Thus, the genes here in this question are to be mentioned as ABCD and not as abab.

Crossing over is the process by which the homologous pair of chromosomes do pair up in the Prophase 1 of meiosis 1 division and they exchange a particular part of their DNA with each other. This leads to exchange of genes between the homologous chromosomes, which will form different gametes in near future. This brings about a variation between the offsprings of same individuals.

Here the d gene of the two chromosomes are getting exchanged.

So the chromosomes will become ABCD, abCD and abCd, abcD respectively.
