pickupchik [31]
Salinity refers to an increase in the dissolved salt content of a body of water. Salinity has great impacts on the type of organisms that live inside the water. In the question given above, the salinity occurs as a result of non natural influence; since most of the organisms living inside the water before probably have specific optimal salinity range, if the salinity exceed the range they can cope with, they will probably migrate away from the water, those that refuse to migrate will probably die out and new species which can cope with the salinity level will emerge.

In photosynthesis, carbon dioxide is reduced and h2o is oxidized. What type of chemical reaction is this?.
Vilka [71]

In photosynthesis, carbon dioxide is reduced and H₂O is oxidized. The type of chemical reaction is an oxidation-reduction reaction.

<h3 />

Explanation

Oxidation-reduction reaction are reactions that take place in electrochemical processes. Reduction is the reaction of decreasing oxidation number and increasing electrons and it can be said that reduction is the reaction of a substance losing oxygen. Oxidation is the reaction of increasing the oxidation number and decreasing electrons and can be said that oxidation is a reaction where the reaction of a substance binds oxygen.

Photosynthesis is one type of oxidation-reduction reaction that occurs naturally in everyday life. Photosynthesis has a complex process and involves green plants and certain bacteria. In the event of photosynthesis, carbon dioxide is reduced to carbohydrates and water is oxidized to oxygen.

The oxidation-reduction reaction in photosynthesis is:

6CO₂(g) + 6H₂O(l) + energy --> C₆H₁₂O₆(aq) + 6O₂(g)

Mrac [35]

Answer:

Afferent arteriole

Explanation:

A glomerulus is formed from the afferent blood vessels, a branch from the renal artery. The afferent arteriole collects blood from the glomerulus and extends to the renal tubule where it divides into capillaries that ramify the tubule. The afferent arteriole is wider than the efferent arteriole.
