In this situation, I would try not to allow the exploitation of the mountain to occur, degrading nature and the property that her family has, because her brother may look for another job, but nature would not recover.

<h3>What are the impacts of coal mining?</h3>

The burning of coal for energy produces highly toxic effluents, such as mercury and other heavy metals such as vanadium, cadmium, arsenic and lead. In addition, the release of carbon dioxide causes pollution in the atmosphere, exacerbating global warming and contributing to acid rain.

With this information, we can conclude that Sedimentation and pollution of rivers due to improper disposal of unused material would make life on the family's property unfeasible.

Answer:

The correct answer is A) Histone deacetylation generally decreases gene expression.

Explanation:

Histones are the proteins that are responsible for the condensation of chromatin, which is directly linked to the capacity that a gene has to be expressed. The more condensed a gene is, the less expressible it becomes.

In order to regulate the gene expression, histones can suffer from many modifications that can change their conformation and the expressiveness of specific genes.

<u>Histone acetylation is linked with an increase of gene expression; while deacetylation and methylation decrease gene expression.</u>

Can a pure culture containing a single type of microbe be prepared from a culture with a mixture of cells? explain your reasonin
Arada [10]

Pure culture can be prepared from a mixture of cultures by using the streak plate method. This enables the bacterial cells to be diluted to obtain a pure culture after many-folds dilution.

Pure culture is the one in which only one species, strain or clone of bacteria are grown. The pure culture enables to scientists to study in detail about its anatomy, lifestyle and potential uses or harms, without the interference of any other microbe.

Streak-plate method is the most commonly used technique in microbiology labs to isolate a single type of bacteria. It is performed by creating the smears of bacteria in zig-zag motion to dilute its concentration.
