The Steady State Theory state that the density of the universe was remaining constant.
<h3>Steady State Theory:</h3>
In cosmology, a steady-state theory is a perspective that holds that the universe is constantly expanding while maintaining a constant average density. According to this theory, the matter is continuously created to form new stars and galaxies at the same rate that older ones fade away due to their expanding distance and accelerating recession. The average density and configuration of galaxies are the same as any location in a steady-state universe, which has no beginning or end in time.
British scientists Sir Hermann Bondi, Thomas Gold, and Sir Fred Hoyle first proposed the hypothesis in 1948. Hoyle expanded on it in order to address issues that had come up in relation to the alternative big-bang theory. According to the hypothesis, in order to maintain a constant average density of matter across time, the new matter must constantly be created, primarily as hydrogen. With nearly five times as much dark matter, the amount needed is small and not immediately observable: one solar mass of baryons per cubic megaparsec every year, or one hydrogen atom per cubic meter every billion years.

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>

Answer:
There is strong and increasing evidence the Endangered Species Act is causing widespread harm to the species it is supposed to protect-to the extent the Act may be doing more harm than good. The Act makes otherwise normal and legal forms of land and resource use illegal, such as farming, home building and cutting timber. The Endangered Species Act’s severe penalties-$100,000 and/or 1 year in jail for harming a single species or even unoccupied habitat that is deemed suitable-turn species in to liabilities. As a result, landowners seek to reduce their liabilities in a number of ways.
