What is the result when a single cell reproduces by mitosis? two cells with genetic material identical to the parent cell
two cells with half the genetic material of the parent cell
four cells with half the genetic material of the parent cell
four cells with genetic material identical to the parent cell

The answer is two cells with genetic material identical to the parent cell.

Explanation: I am also studying this in class and we went over many instances where this question was brought up and the correct answer is four cells with genetic material identical to the parent cell because besides the fact that when you reproduce one cell you get two cells, (which makes logical sense from both a science and a math standpoint) you always have identical DNA to the parent cell and you never get half of it or else it would mess up the whole reproductive process.

1. atmosphere

2. troposphere

Explanation:

1. Weather on Earth is caused by heat from the sun and movement of the air. All weather happens in the lower layer of Earth's atmosphere, which is a layer of gases surrounding Earth. The sun's heat warms the air in this layer to different temperature levels in different places. ... This movement of air is what we call wind.

2. The troposphere is the lowermost layer of the Earth's atmosphere. Most of the weather phenomena, systems, convection, turbulence and clouds occur in this layer
