<span>An example of an epithelial tissue where gases are exchanged is alveolar epithelium, which can be found in the lungs. This tissue is simple epithelial tissue. This is to be expected because the cell layer needs to be thin enough for the gasses like carbon dioxide and oxygen to diffuse or pass through. Stratified epithelial tissue contains several cell layers that would impair the exchange of gasses.</span>
Agricultural practices relating to irrigation have the tendency to reduce the water level of river basins.
<h3>What are the effects of irrigation agriculture on river basins?</h3>
Irrigation agriculture requires that crops are watered artificially and this requires a water source. Hence, waters in river basins suffer and this leads to a reduction in their levels.
Water quality is impacted by agricultural practices such as the use of agrochemicals and fertilizers. Agrochemicals are washed into water bodies and this impacts biodiversity life in water.
One conservation strategy to reduce the impact of this kind of agricultural practice would be to practice organic farming. A farming practice that is devoid of using agrochemicals or the ones that are not poisonous to biodiversity and are biodegradable.

The right answer is A.
The methylation profile of DNA is not obtained when DNA sequencing is performed.
Methylation is a process that can occur in DNA especially at the cytosine level. And this has a very important role in gene expression as it is part of the epigenetic expression.
Gene methylation can induce or repress gene expression depending on the localization of methylated bases.
