How many times larger is the co2 concentration in 2018 compared to Pre-industrial times?

Biology
1 answer:
Bond [772]4 years ago
6 0

The concentration of carbon dioxide (CO2) in Earth's atmosphere is approaching 397 ppm (parts per million) by volume as of May 2012 and rose by about 2.0 ppm/yr during 2000–2009. This current concentration is substantially higher than the 280 ppm concentration present in preindustrial times, with the increase largely attributed to anthropogenic sources.

Question 1
Ugo [173]

Answer:

C Differences among temperature, air pressure, and density

Explanation:

Classification of the atmosphere layer will be different based on the temperature, air pressure, and density.  Generally, air pressure and density will go less at the higher layer, but the temperature varies greatly. Altitude and latitude define a location on earth, not the layer of atmosphere. Most weather just happens at the troposphere layer. The distance from ground level can be used as a rough estimate but not as precise criteria.

Which source is the LEAST credible for scientific information?
Margarita [4]

Answer:

D) A Survey of fellow classmates

Explanation:

This is the correct answer because an informal survey involves various answers that may or may not be accurate.  Informal surveys cannot be held as scientific fact and are, therefore, not reliable. A scientific journal is reliable because it most likely includes data from an experiment and/or research of a trusted scientist or group. The results of past experiments are very reliable because these are the results of hard work and thorough planning and research. A scientific discussion with colleagues is not very credible because it involves the sharing of opinionated information, but it is certainly more reliable that the varying answers of school-aged peers.

Diffusion will continue to occur between the inside and the outside of a cell until what is reached?
Vadim26 [7]


The correct answer is B (Equilibrium).

Diffusion will continue to occur until a state of equilibrium is attained.

Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. The molecules will tend to move into any space available until they are evenly distributed  throughout this space.

When there is no longer a concentration gradient, there will be no net movement of molecules from one area to another. This state is known as dynamic equilibrium.
