External factors include physical and chemical signals. Growth factors are proteins that stimulate cell division. – Most mammal cells form a single layer in a culture dish and stop dividing once they touch other cells. Two of the most important internal factors are kinases and cyclins.

All organisms are grouped into five kingdoms. Those are Monera, Protoctista, Fungi, Plantae and Animalia. The division is made based on 3 criteria. Those are cellular organization, arrangement of cells, and type of nutrition. Cellular organization is whether they are eukaryotic or prokaryotic. Cell arrangement is whether they are unicellular, multicellular, with or without true tissue differentiation etc. Type of nutrition is whether they are autotrophic or heterotrophic.

This is data from a visible satellite image. What types of weather conditions are associated with the image?
masya89 [10]
Hurricanes (also known as typhoons or cyclones, depending on the location on Earth where they form) are often associated with extremely powerful winds and torrential rains. I am not sure about the pressure, but the only option here that mentions both strong winds and a lot of rain is A. low pressure, high winds, high precipitation, so I'd say that is the correct answer.
