Answer:
The flower colour ratio obtained is: Blue : Purple = 3 : 1.
Explanation:
- According to the question,
- the genotype, AABB or AaBb or AABb or AaBB gives blue phenotype.
- the genotype, AAbb or aaBB or Aabb or aaBb gives purple phenotype.
- Red phenotype is for the aabb genotype.
- As only the presence of dominant allele is mentioned but whether it is homozygous or heterozygous is not mentioned, in 1. we consider that presence of a single dominant allele A or B in either locus is capable of showing a blue phenotype, irrespective of the nature of the other allele.
- In 2. we consider that the presence of a single dominant allele, A or B in one locus with recessive pairs of alleles in the other locus is sufficient to develop the purple phenotype.
- The aaBb individual will produce the gametes: aB, ab.
- The AABb individual will produce the gametes: AB, Ab.
- Crossing them,
aB ab
AB AaBB AaBb
(Blue) (Blue)
Ab AaBb Aabb
(Blue) (Purple)
- Of the offspring obtained, 3 have blue phenotype and 1 has purple phenotype.
- Hence, they have the following phenotypic ratio:
Blue : Purple = 3 : 1.

Answer:
- Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O
- Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O2
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration. We breathe in that oxygen, which is carried through our blood to all our cells. In our cells, oxygen allows cellular respiration to proceed. Cellular respiration works best in the presence of oxygen. Without oxygen, much less ATP would be produced.
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.
Explanation:
<span>Yes, the lymphatic system absorbs glucose that is absorbed by small intestines for transport. this is done by the process of passive diffusion the glucose is taken into the blood stream.Along with this water.</span>
