Answer:

Carbon Cycle

Steps of the Carbon Cycle

CO2 is removed from the atmosphere by photosynthetic organisms (plants, cyanobacteria, etc.) and used to generate organic molecules and build biological mass.

Animals consume the photosynthetic organisms and acquire the carbon stored within the producers.

CO2 is returned to the atmosphere via respiration in all living organisms.

Decomposers break down dead and decaying organic matter and release CO2.

Some CO2 is returned to the atmosphere via the burning of organic matter (forest fires).

CO2 trapped in rock or fossil fuels can be returned to the atmosphere via erosion, volcanic eruptions, or fossil fuel combustion.

Nitrogen Cycle

Steps of the Nitrogen Cycle

Atmospheric nitrogen (N2) is converted to ammonia (NH3) by nitrogen-fixing bacteria in aquatic and soil environments. These organisms use nitrogen to synthesize the biological molecules they need to survive.

NH3 is subsequently converted to nitrite and nitrate by bacteria known as nitrifying bacteria.

Plants obtain nitrogen from the soil by absorbing ammonium (NH4-) and nitrate through their roots. Nitrate and ammonium are used to produce organic compounds.

Nitrogen in its organic form is obtained by animals when they consume plants or animals.

Decomposers return NH3 to the soil by decomposing solid waste and dead or decaying matter.

Nitrifying bacteria convert NH3 to nitrite and nitrate.

Denitrifying bacteria convert nitrite and nitrate to N2, releasing N2 back into the atmosphere.

Oxygen Cycle

Oxygen is an element that is essential to biological organisms. The vast majority of atmospheric oxygen (O2) is derived from photosynthesis. Plants and other photosynthetic organisms use CO2, water, and light energy to produce glucose and O2. Glucose is used to synthesize organic molecules, while O2 is released into the atmosphere. Oxygen is removed from the atmosphere through decomposition processes and respiration in living organisms.

What do you think caused the balloon to expand

Anna71 [15]

Pressure on the inside of the balloon was greater than the pressure on the outside of the balloon so it pushed out until the pressures equalized.

When rubbed against a silk cloth, a glass rod loses electrons. How does this affect the charges of the glass rod and the silk cl

AURORKA [14]

Answer:

Explanation:

The glass rod losses electrons because the silk cloth has a positive charge so it attracts the negative charge of the glass rod.

Sarah is writing a paper explaining protein formation. Choose the correct way to complete each sentence.

Amanda [17]

Answer :

Amino acids join by forming (1) peptide bonds. Water is released.

The chains of amino acids vary according to their (2) side chains, which each have differing makeup.

These chains determine the protein’s structure and they fold to create a unique (3) third-dimensional shape.

Explanation :

Amino acid : The amino acids are the building blocks of protein. Amino acids are the compound which consist both amine $(-NH_2)$ and carboxylic $(-COOH)$ groups along with the side chains. In the protein, many amino acids are linked by the peptide bonds.

Th peptide bonds are formed by the combining of amino group of one amino acid to the carboxylic group of another amino acid by releasing of water.

Some examples of amino acids are glycine, lysine, alanine, etc.

Peptide bond formation image is shown below.

In the image 'R' can be contained by different groups like hydrogen, methyl, phenyl, etc

Of the following equilibria, only ________ will shift to the right in response to a decrease in volume. N2 (g) + 3H2 (g) 2NH3 (g

igomit [66]

Answer:

Of the following equilibria, only one will shift to the right in response to a decrease in volume.

$N_2 (g) + 3H_2 (g)\rightleftharpoons 2NH_3 (g)$

On decreasing the volume the equilibrium will shift in right direction due to less number of gaseous moles on product side.

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

Decrease the volume

If the volume of the container is decreased , the pressure will increase according to Boyle's Law. Now, according to the Le-Chatlier's principle, the equilibrium will shift in the direction where decrease in pressure is taking place. So, the equilibrium will shift in the direction number of gaseous moles are less.

$N_2 (g) + 3H_2 (g)\rightleftharpoons 2NH_3 (g)$

On decreasing the volume the equilibrium will shift in right direction due to less number of gaseous moles on product side.

$2 Fe_2O_3 (s) \rightleftharpoons 4 Fe (s) + 3O_2 (g)$

On decreasing the volume the equilibrium will shift in left direction due to less number of gaseous moles on reactant side.

$2 SO_3 (g) \rightleftharpoons 2 SO_2 (g) + O_2 (g)$

On decreasing the volume the equilibrium will shift in left direction due to less number of gaseous moles on reactant side.

$H_2 (g) + Cl_2 (g) \rightleftharpoons 2 HCl (g)$

On decreasing the volume the equilibrium will shift in no direction due to same number of gaseous moles on both sides.

$2HI (g) \rightleftharpoons H_2 (g) + I_2 (g)$

On decreasing the volume the equilibrium will shift in no direction due to same number of gaseous moles on both sides.
