What is equilibrium?
Answer:In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.
Explanation:
Answer:
Equilibrium means when the concentrations of reactants and products are in an unchanging ratio. Another way of saying this is that a system is in equilibrium when the forward and reverse reactions occur at equal rates.

Greenhouse gases are measured by their ability to trap outgoing solar radiation and convert it to heat, warming the atmosphere.
Global warming potential is defined as the ability of an atmospheric gas to contribute to increasing global temperatures and
anthropogenic climate change. Carbon dioxide is used as a baseline for global warming potential, with a GWP of 1. What best
explains why CFCs (chlorofluorocarbons) have a GWP
nearly 5000?
Answer:
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat trapping causes changes in the radiative balance of the Earth—the balance between energy received from the sun and emitted from Earth—that alter climate and weather patterns at global and regional scales.
Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years.1 Natural factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.
This change in concentrations causes warming and is affecting various aspects of climate, including surface air and ocean temperatures, precipitation, and sea levels. Human health, agriculture, water resources, forests, wildlife, and coastal areas are all vulnerable to climate change.
Many greenhouse gases are extremely long-lived in the atmosphere, with some remaining airborne for tens to hundreds of years after being released. These long-lived greenhouse gases become globally mixed in the atmosphere and their concentrations reflect past and recent contributions from emissions sources worldwide. Others, like tropospheric ozone, have a relatively short lifetime in the atmosphere.

B). Group 2, they said that mitosis is involved in the growth and repair of cells and undergoes cell division once, while meiosis is involved in sexual reproduction and undergoes cell division twice.
C). Group 3, they said that mitosis is involved in sexual reproduction and undergoes cell division twice, while meiosis is involved in the growth and repair of cells and undergoes cell division once.
D). Group 4, they said that mitosis is involved in sexual reproduction and undergoes cell division once, while meiosis is involved in the growth and repair of cells and undergoes cell division twice.
Answer:
B)
Explanation:
Several groups of students were comparing the processes of mitosis and meiosis. Each group came up with a different answer for how the two processes are different.
Mitosis- growth and repair one cell division 2 genetically identical diploid cells
Meiosis- produce gametes, two cell division, 4 genetically different haploid cells
Hope this helps :)
The group that is correct regarding mitosis and meiosis is group 2 as they said that mitosis is involved in the growth and repair of cells and undergoes cell division once, while meiosis is involved in reproduction through fusion of gametes and undergoes cell division twice. The correct option is B.
What is cell division?Type of cell division by which a parent cell divides into two or more daughter cells when a parent cell divides into two or more daughter cells. Cell division is typically part of a larger cell cycle.
Cell division occurs in two stages namely mitosis and meiosis. When most people say cell division, they're referring to mitosis, the method by which new body cells are formed.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
The group 2 is stating the same that mitosis is the division for growth and repair and is done in only once, and meiosis is the process of gamete formation and occurs twice.
Thus, the correct option is B.

*Please Help* Invertebrates have a higher net production efficiency than mammals. Which statement most likely explains this observation?
A. Invertebrates are more abundant than mammals in an ecosystem.
B. Mammals maintain their body temperature; invertebrates don't.
C. Most mammals are secondary consumers. Most invertebrates are primary consumers.
D. Invertebrates have smaller bodies than mammals.
Answer:
C. Most mammals are secondary consumers. Most invertebrates are primary consumers.
Explanation:
Net production efficiency (NPE) refers to how efficient an organism at one trophic level utilizes and transfers energy to the next trophic level. Ceetain organisms called CONSUMERS obtain energy by feeding on other organisms. They use this energy for their metabolic activities and transfer the rest when eaten or fed on.
As the trophic level increases, the net production efficiency decreases. This is because organisms at the lower level use energy less than those at higher trophic levels. In this question, invertebrates are mostly PRIMARY CONSUMERS (lower trophic level) while mammals are mostly SECONDARY CONSUMERS (higher trophic level). Therefore, invertebrates use energy more efficiently (less) than mammals, making them have a HIGHER net production efficiency than mammals.
