Which best describes this type of reaction?
makvit [3.9K]

Explanation:

There are two classes of nuclear reactions which are:

  1. Nuclear fission
  2. Nuclear fusion

In nuclear fission, a radioactive isotope which has a heavier nucleus spontaneously disintegrates(breaks up) into 2 lighter nuclei and several neutrons with a large release of energy.

A nuclear fusion occurs by the combination of small atomic nuclei into larger ones with the release of a large amount of energy.

I hope you can make the best choice from this explanation.

Carmen’s psychiatrist has prescribed a selective serotonin reuptake inhibitor to help Carmen feel better. Carmen has most likely
sergiy2304 [10]

Answer:

Carmen has most likely been diagnosed with depression.

Explanation:

Selective serotonin reuptake inhibitors are most commonly prescribed to treat depression. These drugs treat depression by increasing levels of serotonin in the brain, which is one of the neurotransmitters that carry signals between neurons.  They block the reabsorption of serotonin into neurons, which makes more serotonin available to improve the transmission of messages between neurons and thus ease the symptoms of the disorder.

Which statements about the modification of chromatin structure in eukaryotes are true? Select all that apply. View Available Hin
Kay [80]

The correct answers are:  

  • Methylation of histone tails in chromatin can promote condensation of the chromatin.
  • DNA is not transcribed when chromatin is packaged tightly in a condensed form.
  • Acetylation of histone tails is a reversible process.
  • Some forms of chromatin modification can be passed on to future generations of cells.  
  • Acetylation of histone tails in chromatin allows access to DNA for transcription.

Histone modifications are post-translational modifications of histone protein that can affect gene expression by altering chromatin structure or recruiting histone modifiers.The most common modifications are methylation, phosphorylation, acetylation and ubiquitylation. All of them affect the binding affinity between histones and DNA and thus loosening (gene activation) or tightening (gene repression) the condensed DNA.

Histone methylation is a transfer of methyl group by histone methyltransferases to lysine or arginine amino acid of protein. Effect of methylation depends on the type of protein that is modified. Demethylation is the reverse process.

Histone acetylation is the process of adding of an acetyl group(by  histone acetyltransferases) to histone proteins and it can also activate or inhibit the gene expression. Deacetilation is reverse process.
