There are three bypass reactions in gluconeogenesis, out of them the one reaction which does not show reciprocal regulation is Pyruvate carboxylase and PEP carboxykinase bypass pyruvate kinase reaction.
The three bypass reactions where the energy transfer of ATP→ADP takes place are:
- Glucose-6- phosphate bypasses the hexokinase step which is a reciprocal step
- Fructose 1,6 bisphosphate bypasses the phosphofructokinase step, this step is also a reciprocal regulating step.
- Pyruvate carboxylase and PEP carboxykinase bypass pyruvate kinase step is not a reciprocally regulated step, this reaction is the last step of gluconeogenesis leading to the formation of 2 molecules of pyruvate.

Answer:
d. incomplete dominance
Explanation:
When none of the alleles of a particular locus completely masks the expression of the other allele of the same gene, it is called incomplete dominance. If the allele B gives "blue" phenotype and allele b gives white phenotype, a cross between blue (BB) and white (bb) parents would produce all the progeny with genotype Bb. Since the allele B does not completely prevent the expression of allele b in the heterozygous condition, the phenotype of the F1 hybrids would be "light blue". Therefore, it is an example of incomplete dominance.
blue (BB) x blue (BB) = all blue (BB)
white (bb) x white (bb)= all white (bb)
blue (BB) x white (bb)= all light blue (Bb)
Carbon dioxide fixation in plants occurs at the STROMA.
Carbon dioxide fixation is the first step in the Calvin cycle and it occur in all plants. Carbon fixation is the process by which inorganic carbon is converted to organic compounds by the plants. The process of carbon fixation converts carbon dioxide and ribulose biphosphate into 3 phosphoglycerate.
An air mass is a large volume of air in the atmosphere that is mostly uniform in temperature and moisture. Air masses can extend thousands of kilometers across the surface of the Earth, and can reach from ground level to the stratosphere—16 kilometers (10 miles) into the atmosphere.
Air masses form over large surfaces with uniform temperatures and humidity, called source regions. Low wind speeds let air remain stationary long enough to take on the features of the source region, such as heat or cold. When winds move air masses, they carry their weather conditions from the source region to a new region. When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity. This can create a severe storm.
Answer: 101 neutrons
An element's atomic number is the number of protons in its nucleus. X has 52 protons. The mass number is simply the number of protons AND neutrons in the nucleus. Since 52 is given, it's correct to assume that the remainder consists of neutrons. 153-52 will give you the number of neutrons.
Hope this helps! :)
