Answer:
The subatomic particles in the nucleus of a carbon atom are protons and neutrons.
Explanation:
The atomic nucleus contains protons and usually neutrons (except for hydrogen-1 (protium) atoms. The number of protons is an element's atomic number and is the same for all atoms of an element. Carbon has atomic number 6. So all atoms of carbon have 6 protons in their atomic nuclei. Carbon atoms also contain neutrons in their atomic nuclei, which may number 6, 7, or 8.

Which major environmental change is occurring today that could cause the next mass extinction? (1 point)
O deforestation
O climate change
O oil spills
o extreme weather events
Answer:
climate change. this question answer
The wide and rapid decrease in the population of the species of the ecosystem is called mass extinction. Climate change could be the reason that will cause mass extinction.
What is climate change?Climate change is the variation and the shift of the weather and temperature pattern of the atmosphere due to human activities like the burning of fossil fuels and deforestation.
Deforestation is the mass destruction of trees and results in drought and flood. It is one of the factors of climate change. Similarly, extreme weather conditions are also the factor of climate change.
Oil spills cannot be the exact factor for mass extinction but can play a role as they affect the aquatic ecosystem and the lives of aquatic animals.
Therefore, option B. climate change can cause mass extinction.

Which condition can increase a plant's rate of transpiration
Open stomata can increase the plants rate of transpiration.
What is transpiration?Transpiration refer to the process by which water move all through the plant and its evaporated from aerial parts like leaves, stems and flowers. Water is very essential for plants but only a small amount of water taken up by the roots and this is use for plants growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.
Open stomata allow the evaporation of water to the atmosphere.
Therefore, Open stomata can increase the plants rate of transpiration.

These graphs show a change in four types of greenhouse gases from 1975 to 2015. Based on the results of your experiment, how might these changes in greenhouse gases affect Earth’s temperatures? Which is the only greenhouse gas to show a downward trend in its concentration?
Start with the temperature at 25 ºC and the pH at 7. Do not vary these parameters while testing for substrate (Initial Lactose) concentration, as they are environmental controls. Substrate (Initial Lactose) concentration is in mg/dL.
Vary the substrate (Initial Lactose) concentration by 250 mg/dL, starting with 0 mg/dL.
Click the green ‘Run’ button.
After the experiment runs, click the graph between 2 and 4 minutes and move it until the time underneath the graph shows ‘Minutes: 3’ and hold it there.
Answer:
The results show that the increase in the substrate concentration is increasing the rate of the reaction. We can see that the reaction rate has increased to 2.88mM/min. After this even if we increase the substrate concentration
