The correct answer is: B) decreased chromatin condensation
Histone modifications which include phosphorylation, methylation, acetylation and their reverse processes are post-translational modifications that can regulate gene expression. Their effect depends on the amino acid (protein) that is modified, and the combination of the other modifications.
These modifications regulate gene expression by organizing the genome into active form-euchromatin, where DNA is accessible for transcription, or inactive-heterochromatin, where DNA is less accessible for transcription.
Take both parent's genotypes and create a punnett square. This helps determine what percentage of genotypes their children will have.

Photosynthesis is a series of metabolic reactions by which plants synthesize biomolecules by using sunlight. During this process, plants use simple molecules (H2O, CO2) to create oxygen and chemical energy.
- During photosynthesis, chemical energy is stored in the chemical bonds of simple carbohydrates (e.g., glucose).
- The statement above IS NOT TRUE because plants need to sequester nitrogen from the soil to build amino acids.
- Carbohydrates are biomolecules consisting of Hydrogen, Carbon, and Oxygen.
- Plants require Nitrogen, Phosphorous and Sulfur from the soil in order to to create different biomolecules such as proteins (whose building blocks are amino acids) and nucleic acids.
