Answer:
<u>Living things are derived from single units and show several characteristics such as growth respiration, response to stimuli, homeostasis, evolution, and reproduction.</u>
Explanation:
The natural world comprises several biotic or living and abiotic, non-living factors. Cells, are considered the smallest unit capable of supporting life. All living, or biotic factors must be able to grow, carry out respiration- a process that produces energy, and reproduce (pass on genes). They also show some level of organization or complexity, and respond to stimuli. Additionally, living organisms exhibit homeostasis or control over their internal environment and evolve or change over time to adapt to their external environments.
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>
