Answer:

Both gene expression and DNA micro array study about the expression of gene during different stages of development.

Explanation:

The main purpose of gene expression studies is to determine the level of mRNA expressed at different stages of transcription in a tissue or at different stages of cellular development. If a gene is not “ON” during synthesis of RNA and protein, then the desired proteins are not produced. Such studies allow us to turn on such genes.  

DNA microarray  assays easily identify and determine the network of gene expression across the entire genome. The common application of DNA microarray include – mutation analysis and detection, assessment of gene cop, immunoassays etc.

joja [24]

Scientific method includes some steps that are necessary for conducting the successful experiment.

1. Make an observation

You observe the growth of the plant under the influence of light (phototropic effect) and you notice that some plants successfully grow under artificial light. You want to compare that growth with growth under the sunlight.

2. Ask a question

How does the light influence plant growth?

Are the wavelengths of the light important?

Is natural light source (sun) better for plant growth...

3. Form a  hypothesis - it is a testable potential answer to the question

For example: Sunlight induces higher phototropic reaction.

4. Make a prediction

Sunlight is richer in red and blue hues which are both extremely important to plant growth.  

5. Test the prediction

Design an experiment by putting one pot with beans outside on sunlight and other under the light bulb. Other conditions such as water must be the same. Monitor their growth for about 2 weeks and measure the results.

6. Analyze the data and make a conclusion.

GrogVix [38]

The theory that explains this scenario is the tragedy of the commons theory.

<h3>What is the tragedy of the common theory?</h3>

It is an economic theory that explains how individual gains create a general problem in society at large.

When individuals pursue personal gains even at the expense of creating a general problem in society, it results in the tragedy of the common.

Indiscriminate dumping of garbage in the ocean by countries results in a general problem that affects the entire world vis a vis the collapse of many fishing industries.

Fishes represent a source of protein for man all over the world.

hammer [34]

Answer:

Forest.

Explanation:

Berries and nuts are typically fruits and products of trees, and there must be plentiful amount in which to have a population (though it states only an organism, but it can be assumed). Brown fur is typically <em>camo</em> against a brownish background, which can be reflected essentially through bark & wood of trees.

*Most likely the given organism is a squirrel, which typically prefer forest or habitats with trees or tree-like objects.
