The answer to this question is "the nitrogen-fixing bacteria"

Nitrogen-fixing bacteria are a type of organisms that transform nitrogen to a form that is useful to plants. These microorganisms are capable of transforming atmospheric nitrogen into fixed nitrogen.

The answer is nitrogen-fixing bacteria.

Plants are not able to directly use atmospheric nitrogen. It must be converted into different form through a nitrogen cycle. In the process of nitrogen fixation, nitrogen fixing bacteria converts atmospheric nitrogen into ammonium. In the process of assimilation, plants incorporate ammonium into proteins.

Some legumes have a symbiotic relationship with bacteria that live in their root system. These bacteria are called Rhizobia and have the ability of nitrogen-fixation.

You feed a canned dog food that is 75% moisture. When analyzed, it contained 30% crude protein and 1.20% calcium on a dry matter

SVETLANKA909090 [29]

To solve the problem, let us note that the calcium percentage no longer considers the moisture content of the canned dog food. Taking the 75% of the sample 681 grams results in a moisture content of 510.75. This is "removed" from consideration and we're left with 170.25 grams which we multiply with the given (dry basis) percentage of calcium to get 2.043 grams of Calcium.

Oxygen gas is one of the products of photosynthesis.

Which reactant is the source for oxygen gas and how is it released?

A .

Water, released when sunlight splits it into oxygen and hydrogen ions

B .

Glucose, released when glucose is broken down into carbon dioxide gas, oxygen gas and water

C .

Carbon dioxide, released when sunlight splits it into carbon and oxygen gas

D .

Electrons, released when they strike the chloroplasts

Green plants capture energy and convert it into chemical energy by the process known as photosynthesis. During photosynthesis, carbon dioxide and water are transformed into simple carbohydrates and oxygen is liberated into the atmosphere.

light

6CO2 + 12H2O ----------------> C6H12O6 + 6O2

chlorophyll

Water is also used as a source of hydrogen required for reduction of carbon dioxide to form carbohydrate.

Water is oxidised in presence of light and chlorophyll. Hydrogen is removed from water and oxygen is released as follows:

light

4‎H20 ---------------> 2‎H20 + 4H+ + 4e− + O2

chlorophyll

or,

2‎H2O ----------------> 4H+ + 4e− + O2

Hence the source for oxygen gas is water and it is released when water splits in the presence of sunlight into oxygen and hydrogen ions.

So, the correct answer is 'Water, released when sunlight splits it into oxygen and hydrogen ions'.
