Answer:
There is (from closest to the surface of the Earth) ...
Explanation:
Troposphere: the lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere.
Stratosphere: the layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere).
Mesosphere: the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.
Thermosphere: the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. The thermosphere is characterized throughout by an increase in temperature with height.
Exosphere: the outermost region of a planet's atmosphere.

why do pollution levels increase when a ground inversion layer is present?
Answer:
These inversions occur when cold air gets trapped in the valley and a layer of warm air seals it from above. ... The stale air of an inversion allows for the buildup of pollutants created by vehicles, factories, fireplaces, and wildfires.

Hope it helped :)The cell grows in which phases?
A. G1, S, and G2
B. G1 and S only
C. G2 and S only
D. G1 and G2 only
Answer:
D. G1 and G2 only
Explanation:
Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
Answer:
D. G1 and G2 only
Explanation:
During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). A cell in interphase is not simply quiescent.

Organism A is eukaryotic, is unicellular, and lacks a cell wall. Organism B is eukaryotic, is multicellular, has a cell wall, and contains chloroplasts.
In which kingdoms should these organisms be classified?
organism A in Animal and organism B in Fungi
organism A in Animal and organism Bin Plant
organism A in Protist and organism Bin Fungi
organism A in Protist and organism Bin Plant
Answer:
A is protist and B is plant
Explanation:
Animals are multicellular, organism A cannot be an animal. Organism B is a plant and not a fungus because it has chloroplasts. Chloroplasts are organelles in plant cells that help make food through photosynthesis.
The kingdoms in which these organisms should be classified are
organism A in Protist and organism B in Plant.There are a number of features that are shared by a large variety of organisms. The organisms with certain important features in common are put together into one group. The largest of these group is known as kingdoms.
The organism A belongs to kingdom protista because the kingdom bears the following features:
They are eukaryotes bearing membrane bound organelles.They are single-celled (unicellular) lacks a cell wall but contains a definite nucleus.The organism B belongs to kingdom plantae because the kingdom bears the following features:
They contain green pigment known as chloroplasts that enables them make their own food.They are many-celled (multicellular)They are eukaryotes bearing membrane bound organelles.Learn more here:

Answer:
Covering Mouth/Nose
Explanation:
Covering your mouth and nose. The germs spread primarily from your eyes and nose, so coughing and sneezing on objects that are used by a wide multitude of people will obviously affect them as well. Usually masks are used, but if you're careful there will be no need.

Which gas is released into the atmosphere as glaciers melt?
Hydrocarbons
Carbon dioxide
Nitrogen oxides
Ozone
Answer:
The correct answer is B. ) Carbon Dioxide
Explanation:
Took the test and got it right! Hope this helps! Have a good day!
The gas that is released into the atmosphere as glaciers melt is known as carbon dioxide. Thus, the correct option for this question is B.
What is an Atmosphere?An atmosphere may be characterized as a type of envelope that consists of a mixture of numerous gases and surround the planet of the earth and other celestial bodies. It plays a series of functions in order to facilitate the survival of living entities.
As glaciers melt, carbon trapped within the soils is significantly liberated into the atmosphere as carbon dioxide and methane. These gases are released into the atmosphere and definitely cause numerous adverse effects like more warming, which then thaws more the frozen soil.
Therefore, the gas that is released into the atmosphere as glaciers melt is known as carbon dioxide. Thus, the correct option for this question is B.

Which of these could cause the amount of carbon dioxide in the atmosphere to decrease?
Answer:
An increase in the number of producers.
Explanation:
Producers/plants absorb carbon dioxide during photosynthesis and give off oxygen.Therefore to decrease the carbon dioxide in the air,we would have to plant more trees.
Have a nice day.
The percentage of carbon dioxide in the atmosphere should be 0.04% an increase in this amount can adversely affect the environment. Its amount can be decreased by increasing producers.
What is carbon cycle?Carbon cycle is the process of circulating carbon atoms from atmosphere to Earth and then again to atmosphere.
Carbon dioxide is increased in atmosphere by increasing respiration, increasing amount of decomposers, use of fossil fuels.
The way to decrease the concentration of carbon dioxide in atmosphere is by increasing number of producers.
Producers makes their food by absorbing carbon dioxide and release oxygen as a byproduct, hence decreasing the concentration of carbon dioxide.
Thus, the correct answer is D.

True or False:
. Evolution happens because organisms need new features.
. Traits cannot be good or bad, their effect on the success of a creature depends on the environment and circumstances.
. A mutation in an individual is evolution.
. The process of evolution is random, but the selection of genes/traits is not.
. An organism that is more complex is more evolved.
. Only creatures that look similar share a common ancestor.
. “Survival of the fittest” means that the strongest, fastest, fiercest individuals are the ones
that get to reproduce.
. Except for differences between male and female, all individuals in a population are genetically the same.
. Nature is selecting for some traits and against other traits all the time.
. Evolution is a theory that is strongly supported by multiple lines of evidence from multiple fields of study.

What are antibiotics and when can they not be used
Answer:
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. Antibiotics DO NOT work on viruses, such as those that cause: Colds and runny noses, even if the mucus is thick, yellow, or green. Most sore throats (except strep throat) Flu.
Answer:
Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing. Antibiotics do not work on viruses, such as those that cause colds, flu, bronchitis, or runny noses, even if the mucus is thick, yellow, or green. Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics.

What are the reactants for cellular respiration? (1 point)
Answer:
In cellular respiration oxygen and glucose are both reactants. Cellular respiration is mostly based on ATP; carbon dioxide and water from waste products.
Explanation:
Glucose and oxygen are reactive to ATP in cellular breathing. The by-products are water and carbon dioxide. Glycolysis (anaerobic process), a cancer cycle, and oxidative phosphorylation are three steps of aerobic cell breathing.
CO2 + Oxygen CO2 + H 2O C6H12O6 + 6O2 +Water Glucose (sugar), Sugar Cellular breathing, or aerobic breathing is a sequence of chemical processes which, in the presence of oxygen, start with sugar reactants and create carbon dioxide and water as waste products.
