To test for the presence of starch, you can use iodine solution, which turns blue-black in the presence of starch. Lipids can be identified using a Sudan III or Sudan IV test, where lipids will appear as red or orange-stained spots.

Nucleic acids can be detected through tests like the diphenylamine test or the biuret test.

The diphenylamine test produces a blue color in the presence of DNA, while the biuret test results in a purple color in the presence of RNA.

Proteins can also be identified using the biuret test, as proteins will cause the solution to turn purple.

Answer:

A. All are tall and purple

Explanation:

When you set up a punnet square, all of the results would be TtPp.

When a dominant trait is present, it preceeds over the recessive trait. (Also it depends on what genotypes are given. Ex: In flowers if they gave RR shows red, Rw shows pink, and ww shows white, but that's not the case here given that there are only 2 genotypes).

So to break it down:

Tt -> tall plant

Pp -> purple plant

so they are all tall and purple.

Answer: If the heating is done on one small area on the top, there will be convection. If the heating is restricted to a small fraction of the heating area, then within that area the heating will go deeper than anywhere else on the surface. Then the unheated area will have a shallower region of high temperature. Then some convection will occur in the deeper layers, causing some motion on top.

This happens quite a bit during welding. Convection is very significant in welding, even when the heating is from the top.

An individual with a competitive advantage lead to the evolution of an entire species because : ( D ) Individuals that survive due to their competitive advantage are able to expand their range, similar to how the finches radiated out from one common ancestor on the mainland.

The evolution of species is the change in the characteristics of species overtime and this is made possible through natural selection. Individuals with competitive advantage survives better than individual without competitive advantage therefore they lead to the evolution of species through natural selection by expanding their range.

Hence we can conclude that Individuals that survive due to their competitive advantage are able to expand their range, similar to how the finches radiated out from one common ancestor on the mainland.

Explanation:

There are two main factors that affect the density of water, namely, Temperature and Purity.

There are two main factors that make ocean water more or less thick temperature and salinity. Cold, salty water is denser than warm, crisp water and will sink below the less thick layer. The Density of Water can be explained as: It is the weight of the water per unit volume, which depends on the temperature of the water.

The density of water can also be overripe by temperature. When the same amount of water is heated or fresh, its density changes. The density of seawater can be expanded by reducing its temperature, increasing its salinity, or increasing the pressure. Pressure has the least collision that affects the density of ocean water the temperature of the water and the saltness of the water.

So we can conclude that Water's density is affected by its purity, temperature, and depth.

Explanation:

Hope this helps :3

The time that it takes the isotope to decay varies. Sometimes the time is short, and other times it’s long.

Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element's atomic number on the Periodic Table.

Examples of radioactive isotopes include carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238. Some isotopes are known to have extremely long half-lives (in the order of hundreds of millions of years). Such isotopes are commonly referred to as stable nuclides or stable isotopes.

Metamorphic rock, well for your answer just metamorphic.

Explanation:

Because, they are formed from any rocks by heat and/or pressure to create a new rock.

Rocks created from intense heat or pressure deep inside the earth are called metamorphic. Thus, the correct option for this question is D.

Metamorphic rocks are formed when specific rocks are subjected to intense heat, high pressure, hot mineral-rich fluids, or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.

When rock changes its properties or attributes over a period of time due to physical changes like pressure, heat, and different chemical activity.

When sedimentary rocks or igneous rocks undergo this alteration through the physical process such as pressure exposure, heat changes, and tectonic plate movement at the plate edges, metamorphic rocks are formed.

Therefore, rocks created from intense heat or pressure deep inside the earth are called metamorphic. Thus, the correct option for this question is D.

DNA stands for deoxyribonucleic acid. It is defined as the molecules that has genetic material for development of organisms. DNA molecules are made up of two linked strands that  resemble a twisted ladder a shape called as a double helix.

As given there are 100 base pair of DNA molecules, in that 100 base pair there is 23% of cytosine base pair. So, to calculate the the amount o hydrogen atoms in the molecules we can just multiply 23 with 3 as it has 3 hydrogen bonds so the result is 46.

Answer:

D. vertically.

Explanation:

When sharpening a knife with a steel rod, it is important to hold the rod vertically with the tip firmly pressed against the counter. The knife should then be held at a 20-degree angle against the steel rod and moved down and across the rod in a sweeping motion. This process helps to straighten and align the edge of the knife, resulting in a sharper blade. Holding the rod horizontally, diagonally, or rotating it between horizontal and vertical positions would not provide the correct angle for sharpening the knife.
