Epigenetic changes are those which do not involve alterations in the DNA sequence. These are caused due to interaction of the genome with the environment.

<h3>When are alterations epigenetic?</h3>
  • Epigenetic modifications or tags include DNA methylation and histone modification.
  • These changes alter DNA accessibility and chromatin structure thus regulating gene expression.
  • These are the reversible, heritable changes which do not change your DNA sequence, but they can change how your body reads a DNA sequence.
  • These are necessary for the normal development of organisms.
  • Stable, long-term epigenetic modifications involve DNA methylation.
  • Flexible, short-term changes involve histone modifications, such as methylation and acetylation.

If a cell is placed in an isotonic medium, there will be no net movement of water. True or false?.
ASHA 777 [7]

It is true.

<h3>What is isotonic medium?</h3>
  • A solution that has the same amount of salt as cells and blood. In hospitalized patients, isotonic solutions are routinely utilized as intravenous fluids.
  • When a cell is immersed in an isotonic solution, there is no net movement of water into or out of the cell, and the volume of the cell remains constant.
  • Isotonic solutions include 0.9% normal saline and lactated ringers. A hypertonic solution is one that has a greater solute concentration than the solution across the semi-permeable barrier.
  • The isotonic solution allows the cells to move water and nutrients in and out of the cells. This is necessary for the blood cells to perform their function of supplying oxygen and other nutrients to other parts of the body.

A plant is treated with a chemical that blocks the flow of electrons between photosystem II and photosystem I, such that protons
Sindrei [870]

Answer:

Reduce or stop the production of energy molecule i.e ATP

Explanation:

Proton is an essential ingredient to carry out light reactions successfully and the proton requirement is fulfilled through the proton gradient formed along the membrane. A chemical that blocks the flow of electrons thereby hindering the flow of proton will adversely affect the electron transport chain reactions thereby causing reduced/no conversion of ADP to ATP.
