In one sentence explain why carbon dioxide is considered the most important greenhouse gas, although it traps much less heat than other greenhouse gases such as methane, nitrous oxide and CFCs.
Answer:
Because plants need carbon dioxide more than any other compound/element. Also, heat doesn't make much of a difference in a plants growth or production. It's sunlight that makes a difference.
Carbon dioxide is considered as the most important greenhouse gas due to its abundancy in the atmosphere.
• In the atmosphere, climate change is mainly an issue due to high concentration of carbon dioxide in the atmosphere.
• This overload is because of the burning of fossil fuels and burning of forests.
• Apart from carbon dioxide there are many heat trapping gases like water vapor and methane, however, carbon dioxide is putting us at greater threat due to irreversible modifications it takes place if it continues to gather at such rate in the atmosphere.
• Carbon dioxide has contributed more to climate change than any other greenhouse gases between 1750 and 2011.
• The other gases like methane possess more potent heat trapping tendency per molecule in comparison to carbon dioxide, however, they are far less in comparison to carbon dioxide in the atmosphere.
• The tendency of carbon dioxide to remain in the atmosphere for longer durations in comparison to other heat trapping gases makes it the most potent greenhouse gas.
Thus, the abundancy of carbon dioxide in the atmosphere makes it the most powerful greenhouse gas in comparison to other greenhouse gases.

1. During mitosis, a single cell divides to produce two daughter cells. What must happen in the original cell so that each of the daughter cells has a complete set of chromosomes?
Mitosis is the cell division which occurs in all types of cells in the body. This results into formation of daughter cells with same set of genetic material as the parent cell.
What is Mitosis?
Mitosis is a type of cell division which occurs in all types of cells. This division is also called as Equational division as the genetic content remains constant from the parents to offspring. This process results into formation of two daughter cells which are similar to the parent cell.
In mitosis, a cell divides to form two identical daughter cells with same genetic material. It is important that the daughter cells have a copy of every chromosome in their nucleuc, so the process involves copying of the chromosomes first and then carefully separating the chromosomes copies to give each new cell a full set of genetic material.

Question 5 of 10 Match each measurement tool with what it measures. Hygrometer ? Humidity Wind sock ? Air Pressure Barometer ? Wind speed and direction Anemometer ? Wind speed
Answer:
hygrometer measures humidity
barometer measures air pressure
wind sock measures wind speed and Direction
anemometer measures wind speed
The terms with their respective measurable device can be matched as:
1. Hygrometer is a type of device used to measure the content of water vapor or moisture in air or soil.
2. Barometer is a scientific instrument that is used for the measurement of air pressure. Temperature, wind patterns, and the earth's rotation affect the air pressure.
3. Windsock is a type of conical tube that is used to understand the direction of the wind. Windsocks are easily observed at airports and beaches.
4. Anemometer is a type of device, which consists of three spherical plates. The plates are used to measure the speed of the wind.

What theory’s/ideas challenge natural selection? In other words, what disproves natural selection?
Answer:
Natural selection needs some starting material, and that starting material is heritable variation. For natural selection to act on a feature, there must already be variation (differences among individuals) for that feature. Also, the differences have to be heritable, determined by the organisms' genes.

other team warms up for thirty minutes, and then each team records the time that it takes
them to row a specific distance, Identify the dependent variable in this experiment. [1]

Answer: The team that warms up will have there muscles warm and will do a better job during rowing and after theu are done they should stretch again.
Explanation:
The team warms up for thirty minutes and has better results in Olympics.
Why stretching is good before any strenuous activity?Stretching prior to exercise allows the muscles to loosen up and become resistant to the impact they are about to undergo, thereby reducing the chance of injury.
Your muscles and tendons will loosen as a result of proper stretching. During your workout, this will improve your flexibility and range of motion. Performance has improved. Stretching before a workout improves blood flow, suppleness, and range of motion, which boosts overall performance.
