Answer:
The question is incomplete, the complete question is:
Photosynthesis enables plants to produce most of the organic molecules they need . This process requires the use of all of the following reactants except
A. carbon dioxide
B. water
C. light
D. glucose
The correct answer is D (glucose)
Explanation:
Plants are unique set of organisms called autotrophs, because of their ability to make their own food in form of organic molecules. They do this through a process called PHOTOSYNTHESIS. Photosynthesis is the process by which plants synthesize food using sunlight.
Plants are able to perform this process of photosynthesis because of the possession of a green pigment which they use to capture the energy from sunlight, which they then use to power the breakdown of water molecule (PHOTOLYSIS) in the light stage of photosynthesis. They produce certain compounds (ATP, energy-carrier and NADPH, hydrogen carrier) which they use to reduce carbondioxide (CO2) that has been taken in via the stomata in their leaves. This overall process produces glucose (organic molecule), which they use as a source of fuel.
In a nutshell, the reactants are water, CO2 and light to produce glucose (product).
How does the expression of genes and traits of offspring relate to their parents?
Although the operation of natural selection requires that genotypes differ in fitness, for some geneticists it seems easier to understand natural selection than fitness. Partly this reflects the fact that the word “fitness” has been used to mean subtly different things. Here I distinguish among these meanings (e.g., individual versus absolute versus relative fitness) and explain how evolutionary geneticists use fitness to predict changes in the genetic composition
Mitosis is where the chromosome are separated in 2 identical sets of chromosomes and end up with it own nucleus. Meiosis is the division in 1/2 and then in 1/2 again causing 4 identical sets of chromosomes. Hope this helps! If something does not make sense let me know and I will be glad to explain! ;)
