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)

Identify the evolutionary forces that can cause allele frequencies to change from one generation to the next.
Irina-Kira [14]

<u> Allele frequencies to change from one generation to the next.-</u>

<u>B. </u><u>Mutation</u><u>; C. Random genetic drift; D. </u><u>Migration</u><u>; F. Natural selection</u>

  • Selection, mutation, migration, and genetic drift are the mechanisms that effect changes in allele frequencies.
  • When one or more of these forces are acting, the population violates Hardy-Weinberg assumptions, and evolution occurs.

Why do allele frequencies change from one generation to the next?

Random selection: Allele frequencies may fluctuate from one generation to the next when people with particular genotypes outlive those with different genotypes.

No mutation: Allele frequencies may fluctuate from one generation to the next if new alleles are produced via mutation or if alleles mutate at different rates.

What are 5 factors that cause changes in allele frequency?

  • A population, a collection of interacting individuals of a single species, exhibits a change in allele frequency from one generation to the next due to five main processes.
  • These include natural selection, gene flow, genetic drift, and mutation.
