Answer: the correct option is : highly developed cell- cell communication.
Explanation: In complex multicellular organisms, cell - cell communication also known as cell signalling is part of any communication process that leads basic activities of cells and coordinates multiple cell functions.
Bacteria is not as complex as human and other animal lives, which means they need less energy and DNA to evolve in these ways.
Answer:
smog
Explanation:
Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities.
I do believe the answer is B
The phase during which sister chromatids aggregate along the equator of the cell is called the metaphase.
The image shows the process of cell division through mitosis. The mother cell divides into two genetically identical daughter cells in mitosis. There are four main phases in the mitosis process. They are: prophase, metaphase, anaphase and telophase. In the metaphase, the highly condensed sister chromatids line up along the equator of the cell by binding to the microtubles that form the skeleton of the cell. These kinetochores line up the chromatids at the equator to initiate their separation.
