The compound that smells like rotten egg is another pollutant, hydrogen sulfide with the chemical formula of H2S. This is specifically formed in the geothermal power plants because of the presence of the sulfur that when reacted with water or hydrogen may form the hydrogen sulfide.
Coal! it's formed over years from decayed vegetation
The answer is anaphase.
Speaking of mitosis, which is a cell division of a single cell into two identical daughter cells, it consists of 4 phases - prophase, metaphase, anaphase, and telophase and cytokinesis. Chromatids are present only in metaphase and anaphase. During metaphase, sister chromatids join together. During anaphase, sister chromatids separate from each other to the opposite sides of the cell.
Answer:
Excitation is the process in which action potentials in the nerve fiber lead to action potentials in the muscle fiber. There is then a rapid fluctuation in membrane voltage at the motor end plate, called the end-plate potential. Areas of the sarcolemma near the motor plate have gates that open, moving ions, which causes the action potential that excites the muscle fiber. The process begins with a nerve signal stimulating a voltage-gated calcium ion channel to open, allowing the ions to enter the axon terminal. The ions stimulate the release of acetylcholine into the synaptic cleft.
Your correct answer would be "figure B" mainly because of the fact that a polygon would be a shape that would contain no curves what so ever. And as we can see above, figure b would contain this.
Your answer: Option B.
