Answer:
The answer is when the cell express different genes.
Explanation:
Cell differentiation is the process when a cell is changed from one cell type to an other and brings more complexity to the system. A cell before differentiation possess all the genes however their expression in turned off. When some external or internal factors trigger the gene expression it starts the cell differentiation. A multicellular organism undergoes several rounds of cell differentiation during its development. Although cell differentiation changes the size, shape and metabolic activity but the genetic makeup or DNA is never changed during cell differentiation.
I think this stage is the cytokinesis. It is <span>the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase. Hope this helped.</span>

The answers is A; The physical and chemical properties of HCl are different from those of H2 and Cl2.
Explanation;
Hydrogen chloride is a gas, which is a molecule made up of a hydrogen and a chlorine atom bonded by a single bond.
The chemical and physical properties of HCl differs from those of hydrogen and chlorine. For example; they have different molecular weight; HCl is colorless, while chlorine is greenish yellow and hydrogen is colorless
(D) Most of the best sites are inaccessible by land transportation, so making roads to them is often prohibitively expensive.
<h3>What is a Reserve?</h3>
A nature reserve, also referred to as a wildlife refuge, a wildlife sanctuary, a biosphere reserve or bioreserve, a natural or nature preserve, or a nature conservation area, is a protected area that is important for its flora, fauna, or features of geological or other special interest. It is reserved and managed for conservation efforts as well as to offer unique opportunities for study and research.
In some nations, government agencies may designate them, as well as private landowners like charities and research facilities. Depending on the level of protection provided by local regulations, nature reserves are classified into various IUCN categories. It is typically subject to stricter protection than a natural park. In laws and official documents, different jurisdictions may use different wording, such as ecological protection area or private protected area.
