Answer:
Option 1: Eukaryotic DNA can be highly packaged in condensed chromatin and inaccessible to transcription factors and RNA polymerase.
Explanation:
A process in which chromatin is rearranged in such a way that it comes in a state ready to began the transcription is known as Chromatin remodeling.
Basically, what happens during chromatin remodeling is chromatin changes from a condensed state into a suitable state to begin transcription, in which DNA binding proteins and transcription factors have access to bind to the DNA and start the process of transcription or gene expression smoothly.
Significance of chromatin remodeling:
- The process of chromatin remodeling holds immense importance in the expression of genes because if this remodeling will not occur, the most important gene expression controlling factors would not be able to access DNA and start transcription. Therefore, chromatin remodeling must has to be the first step in gene activation.
- When chromatin is tightly packed,it is referred to as heterochromatin. But when chromatin becomes loose and accessible for transcription it is referred to as euchromatin (please see attached figure for a better understanding).
- Once heterochromatin is changed into euchromatin, the process of transcription begins and makes it possible for the expression of genes in a timely and coordinated fashion.

The concentration gradient will be in the direction from the cell to the outside of the cell .
<h3>What is concentration gradient and how the direction is from inside to the outside ?</h3>
- Concentration gradient will be from inside of the cell to the outside of the cell that is from high concentration to the low concentration.
- The concentration of substances inside the cell if given to be more than the concentration of the substance inside the cell.
- We have always studied that the direction of concentration gradient is from high to low.
- Since the concentration inside is high so the direction will start from the higher concentration.
- To the place where concentration is low that is outside of the cell.

Explanation:
Sorry if any of them are wrong!
Explanation:
Cells function differently in unicellular and multicellular organisms, but in every organism, each cell has specialized cell structures, or organelles, of which there are many. These organelles are responsible for a variety of cellular functions, such as obtaining nutrients, producing energy, and making proteins.
hope this helps you
have a nice day:)
First state a Thesis.
Ex. The Water cycle is important to nature because it replenishes water every day.
Next you organize your paper into sub sections.
Ex.
I. Process of the water cycle
A. evaporation ( water evaporates into the air from oceans, lake's, puddles)
B. condensation ( water droplets collect to form a cloud)
C. precipitation ( weather such as snow, sleet, hail, rain)
You should do this until at least 5 sections ( conclusion is last)
Please vote this branliest answer! Thanks.
