Which of the following describes the role of water in supporting the chemical reactions that occur within various life forms? it is used during photosynthesis to capture sunlight. it is used during photosynthesis to release oxygen. it adheres to the vascular tissue in plants. it allows sunlight to pass through it.

It is used during photosynthesis to release oxygen.

Explanation:

The photosynthesis occurs in the leaves of a plant, It is supported by green pigment known as chlorophyll.

During photosynthesis carbondioxide reacts with water to produce glucose.

The role of water is that it produces oxygen or releases oxygen during the reaction of photosynthesis.

The sunlight is being absorbed by the pigment chlorophyll.

The water molecule also provides electron during the process.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
