The answer is C.) The volume of fluid in Image B is greater than that of Image A.
Answer:
Photosynthetic reaction center differ from the chlorophyll molecules in the antenna complex by the presence and absence of core pigment and accessory pigment.
Explanation:
Photosynthetic reaction center contain core pigment known as chlorophyll A which can aborb wavelength of sunlight not more than 700 nm in case of Photosystem 1 and the core chlorophyll pigment of Photosystem 2 absorb light having wavelength of 680nm or less than that.
Antenna complex or light harvesting complex such as chlorophyll b ,Carotenoid,Xanthophyll absorb light energy from sunlight and transfer that light energy to photosynthetic reaction center by resonance energy transfer so that the photosynthetic reaction center uses the same(light energy) in form of chemical energy to out the further reactions of photosynthesis.
Answer: Species can change over time in response to changes in environmental conditions through adaptation by natural selection acting over generations. ... Evolution results primarily from genetic variation of individuals in a species, competition for resources, and proliferation of organisms better able to survive and reproduce.

Answer:
The answer is option "B"
Explanation:
DNA is comprised of a set of genes that dictates a given trait. The genes themselves are comprised of alleles that allow for variations and differences in the trait that the concerned gene is responsible for. In the case of D. Melanogaster, there is an allele that allows for resistance to pesticides such as DDT. The two samples that are referred to in the question are differentiated on the basis of the amount of time that has lapsed since the start of significant DDT usage. So at the time when widespread DDT usage was not in place, the sample showed no DDT resistant alleles. With the passage of time in which DDT usage grew, the resultant effect as evidenced from the later sample indicated a significantly higher percentage of DDT resistant allele. This means that the ability of this species of fruit flies to survive, referred to as their evolutionary fitness, increased only after use of DDT increased. This means that DDT resistance trait changed as a natural response to the introduction of a different climate thereby allowing subsequent offspring of fruit flies to boast of higher numbers of alleles that have DDT resistance capacities thus allowing them to survive.
