Answer:
A) chromosomes is the correct answer.
Explanation:
Chromosomes are present in nuclei of animals and plants and they are composed of protein and DNA.
functions of chromosomes
- Chromosomes are required for the formation of daughter cells, replication and cell division process.
- Chromosomes carry the genetic material called DNA that provides genetic information to carry out the different cellular processes and functions.
Answer:
This is how cells gene regulation occur.
Explanation:
Regulation of gene expression is very very important thing to maintain the normal levels of all body proteins according to our body"s requirement.
During positive gene regulation enzymes of various metabolic pathways of the target cell is being activated,thus supplying the cellular need of various metabolites and proteins.
During negative regulation various enzymes are turned off thus blocking the formation of metabolites or proteins not required by the cell.
The solution is hypotonic. This is because the solute concentration is greater inside the cell than outside the cell.

Scientists learn about the layers deep within the Earth's crust by studying how seismic waves travel ... Usually, they use seismic waves, which are waves generated by earthquakes
FOR MORE EXPLANTION...JUST A LITTLE MORE
NOT REALLY REQUIRED BUT YOU CAN USE JUST FOR YOUR REFERENCE..
Excellent question! Scientists use waves to study the different layers of the earth. Usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test explosions. The seismic waves are bent, sped up, or slowed down, or even reflected when they pass through the earth's layers. Different types of materials (liquid vs. solid, rigid vs. softer) determine the speed of the waves. Bending of the waves occurs at the layer's boundaries. So, scientists study the path and speed of these waves through the earth to decipher boundaries and the materials that make up the layers.
THATS WITH QUESTION 1

Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.
I hoped this helped...
