Answer:

Costly and distilled water is not potable water

Explanation:

Distillation is not considered a practical approach to treat the municipal waste water because of the following two reasons -

a) The municipal water is drinkable i.e potable water and hence it should have certain amount of necessary ingredients which are considered essential for the human body which a distilled water lacks.

b) Distilled water has application in industries, factories etc.

c) Distillation is costly method of water treatment. Thus, until and unless there is requirement of distilled water , there is no need to use distillation method of municipal waste water.

HELP!! DNA was isolated from water samples taken from six different sites. This gel

VladimirAG [237]

After running DNA in a gel, bands of different sizes and species might appear. <em>Scientists know silver carp are at North Shore site 1 because one of the bands in lane 1 matches a band in the positive control (Option C). </em>

When DNA was isolated and run in a gel, many bands migrated to different points.

These bands were the different-sized fragments of DNA samples from different species from the six sites.

<em>Researchers wanted to figure out where the silver carp is. </em>

To do it, they needed to identify the bands on the gel that belonged to the silver carp DNA, so they included negative and positive controls to make comparisons.

<h3>Positive and negative Controls</h3>

Negative and positive controls guarantee the interpretations of the results.

The positive control shows the band sizes that belong to the silver carp DNA.

<em>Any</em><em> band</em><em> in the sampling sites that</em><em> matches</em><em> one of the </em><em>positive control</em><em> bands indicates that the species is present at that site.</em>

The negative control is the opposite. It is the absence of the species' DNA.

<h3>Results interpretation</h3>

As we can see, there are four sites where the bands match one of the bands of the positive control. These are,

North shore site 1
Chicago site 1
Calumet site 1
Calumet site 2

This means that at these four sites, the silver carp is present.

<em>So scientists know silver carp are at North Shore site 1 because one of the</em><em> bands</em><em> in </em><em>lane 1</em><em> matches a band in the </em><em>positive control</em><em> (Option C). </em>

By looking at the lane of the North Shore site 1, we can also see another band (Thinner and grey). But this band does not match either of the positive control bands. This result suggests that the grey band belongs to another species' DNA.

At the beginning of Unit 3 we saw the example of the pygmy seahorse, whose offspring can change their body color, depending on t

Brut [27]

Answer:

Seahorses are between the sea animals that may modification color. Such variations camouflage the creatures if not obscure or perhaps frighten possible predators. Color variations facilitate seahorse’s link emotions and intentions, particularly throughout suit. Whereas these alterations are stunning and infrequently seem seamless, they're truly the merchandise of complicated interactions between the seahorse's brain and small organs carried within its skin.

Anatomy

Seahorse organelles, known as chromatophores, are enclosed at intervals their skins. These tiny, sack like organs contain variety of pigments and may expand or consent response to a spread of stimuli, inflicting the seahorse to vary color. Typically, seahorses carry solely a couple of chromatophore diversities, so completely different colors are created through the blending and matching of accessible pigments.

Building Color

All of the colours to that a seahorse will modification are derived from 3 or four basic stains contained in several chromatophores. The pigment cells of those chromatophores are sometimes stacked on prime of every alternative or clustered along in teams. the colour a seahorse displays is predicated on sort, combination and attentiveness of those cells, moreover as their proximity to the skin's surface.

Brightness and Tone

Muscles hooked up to chromatophores will push stain cells toward, or pull coloring cells off from, the surface of a seahorse's skin. Once the coloring is on the point of the skin's surface, the animal's color is brighter and splendid. In turn, once the pigment attracts off from the skin's surface, the ensuing color is a smaller amount saturated and somewhat boring.

Speed of modification

Depending on the stimulant that causes a seahorse to vary its color, chromatophores are measured by the seahorse's system or by its secretion fluctuations. once the system activates chromatophores, comparable to in life-and-death things, the animal's color changes quickly. once chromatophores are activated by secretion fluctuations, comparable to once a seahorse is suit a mate, the animal's color in its place changes somewhat slowly.

Both of them aren't subjected to action because the color modification in ocean horse are influenced by system and secretion system.

Answer:

<h2>Ethylene is a gaseous hormone in plants, it is a fruit ripening hormone.</h2>

Explanation:

Ethylene is a chemical signal through which ripening fruits trigger the ripening process in fruits, Studies on components of ethylene signaling have shown a linear transduction pathway leading to the activation of ethylene response factors. However, the whole pathway by which ethylene selects the ripening-related genes and interacts with other signaling pathways to regulate the ripening process still not yet fully known. Most fruits produce ethylene that starts the ripening process. Its level in under-ripe fruit is very low, but as fruit develop, the production of ethylene become larger that speed up the ripening process of fruit.
