The answer is rr. In a monohybrid cross, the phenotypic ratio is 3:1 for
dominant trait to recessive trait. Since the ration is 3:1 for round
seeds to wrinkled seeds, we can conclude that round seed is the dominant
trait. Let R be a dominant allele for round seed and r be a recessive
allele for wrinkled seed. The genotypes will be: RR (dominant homozygote
with round seeds), Rr (heterozygote with round seeds), and rr
(recessive homozygote with wrinkled seeds. Thus, only genotype rr is the
genotype of the wrinkled seeds.
Answer:
A. more oxygen to enter the atmosphere
Explanation:
Photosynthesis is a metabolic process unique to the cells of autotrophic organisms, due to the possession of the CHLOROPHYLL pigments used in trapping light energy from the sun. Photosynthesis is the process of combining carbondioxide (CO2) and water (H2O) using energy of sunlight to produce glucose and release oxygen gas.
Based on the understanding of the photosynthetic process which is similar in all photosynthetic organisms including photosynthetic prokaryotes e.g. cyanobacteria, the presence of the photosynthetic PROKARYOTE will allow more oxygen in the atmosphere.
Note that, oxygen is released during photosynthesis.
In multicellular organism the energy is stored in the body in the form of <u>Glycogen</u>.
The cells require a constant supply of energy to generate and maintain the biological order that keeps them alive. This energy is derived from the chemical bond energy in food molecules, which thereby serve as fuel for cells.
Sugars are particularly important fuel molecules, and they are oxidized in small steps to carbon dioxide (CO2) and water.
Other molecules, such as fatty acids and proteins, can also serve as energy sources when they are funneled through appropriate enzymatic pathways.
