DAT(Direct Antiglobulin Test)
A biologist discovers a new signal transduction pathway in fruit flies that involves a protein kinase cascade. As part of a grant proposal he writes to obtain funding for further work on this pathway, the biologist proposes research to look for phosphatase enzymes. Why?.
Phosphatases are regulators of signal transduction pathways.
The biologist must find the enzymes that control the signaling cascade by removing phosphate groups from molecules. Protein phosphatases can act as both immediate and delayed signal transduction regulators, attenuating or boosting signaling.
Protein kinases and phosphatases are enzymes that catalyze the transfer of phosphate from one substrate to another. A protein kinase catalyzes the -phosphate transfer from ATP (or GTP) to its protein substrates, whereas a protein phosphatase catalyzes the phosphate transfer from a phosphoprotein to a water molecule. Despite the fact that both families of enzymes are phosphotransferases, they catalyze opposite processes to modify the structures and activities of numerous prokaryotic cellular proteins and eukaryotic cells.

Two pure-breeding mutant plants produce white flowers. When they are crossed, all of the progeny have wild-type purple flowers. What does this genetic complementation tell you?.
We can infer from the genetic complementarity that more than one gene is involved in phenotypic determination.
Offspring of two different organisms with homozygous recessive mutations exhibit wild-type traits due to genetic complementation. The interaction of two different strains of an organism with homozygous recessive mutations that produce the same trait but do not occur on the same (homologous) gene is referred to as complementation. The progeny display the wild-type phenotype when two organisms with different homozygous recessive mutations that result in the same mutant phenotype mate or cross.
Two pure-breeding mutant plants producing white flowers gave birth to progeny that were wild-type purple blossoms, proving that more than only the white genes are involved in the production of color phenotypes. That is, phenotypic variation is regulated by a recessive gene despite the fact that neither parent expresses this gene.

how is the energy stored in polysaccharides mobilised?
Plants store carbohydrates in long polysaccharides chains called starch, while animals store carbohydrates as the molecule glycogen. These large polysaccharides contain many chemical bonds and therefore store a lot of chemical energy.
Since these large polysaccharides have many chemical bonds, they can store a lot of chemical energy. Whenever these compounds are decomposed all through metabolic activities, the energy in the chemical bonds is released and can be used by cells.
What is a polysaccharide?Polysaccharides are important types of biomolecules. They are long chains of carbohydrate molecules made up of many smaller monosaccharides.
Many polysaccharides are used by organisms to store energy. While energy-producing enzymes only work on monosaccharides stored in polysaccharides, polysaccharides generally fold together and they may contain many monosaccharides in a dense area.
The high energy carbon-hydrogen covalent bonds between the monomers in a polysaccharide store the energy.
The breaking of these bonds is what causes the energy used to generate ATP to be released. The higher the energy content of the polysaccharide, the more of these bonds there are.
Thus, this way, the energy stored in polysaccharides is mobilized.

If heavy exercise produces lots of co2 in the body, will the blood become more acid or more basic?.
If heavy exercise produces lots of co2 in the body, will the blood become more so they breathe faster to prevent the blood from becoming too acidic.
The two main organs that control the pH of the blood are the kidneys and the lungs, frequently both at once. The cells of the body include numerous chemical buffering systems. Through the act of exhaling carbon dioxide, which can occasionally result in changes within seconds, the lungs can quickly help adjust blood pH. For instance, when exercising, a person produces more carbon dioxide and so breathes more quickly to keep the blood from getting excessively acidic.By excreting acids in urine, the kidneys control the blood's pH. Additionally, they generate and control bicarbonate, which raises the pH of the blood. These changes could take hours or days, taking longer than those brought on by breathing.To learn more about blood.

Water will move to the side of the beaker where 3% sodium solution is present from the side where 0.85% sodium solution is present to dilute the sodium on the side of 3% solution through semi-permeable membrane.
What is semi-permeable membrane?
Only some molecules can flow across a semipermeable membrane, which prevents the passage of other molecules. In essence, a semipermeable barrier serves as a filter. Different kinds of semipermeable membranes can filter out molecules of different sizes. A biological or synthetic material can be used to create a semipermeable membrane.
Diffusion is the overall transfer of anything (such as atoms, ions, molecules, or energy) from a region of higher concentration to one of lower concentration. Diffusion is fueled by a gradient in the chemical potential or Gibbs free energy. It is possible for molecules to diffuse "uphill" from a region of lower concentration to one of higher concentration, similar to spinodal breakdown.

People do not use water to adulterate oil, while water is commonly used to adulterate milk why
Oil is hydrophobic by nature, but milk is an emulsion of water and minute fractions of many other substances, including lactose, micro lipids, and fats.
Any liquid that wants to combine with another one needs to have roughly equal amounts of attractive forces acting on its molecules. The attractive forces in water molecules are extremely strong due to the existence of polarity in the molecules.When oil and water are combined, the layers separate because of the long, neutral aliphatic chains in the structure of oils. As a result, there will be less attraction between the molecules of oil and water.Water-in-Oil vs. Oil-in-WaterEmulsions can be either water-in-oil or oil-in-water. Technically, to create water-in-oil emulsions as opposed to oil-in-water emulsions, one phase (referred to as the dispersed phase) is blended with the other (the continuous phase). To put it another way, one liquid acts as a kind of base into which another liquid is added. Oil is the dispersed phase that is spread into the continuous phase, water, when an emulsion is "oil-in-water." Milk is an illustration of an oil-in-water emulsion.A water-in-oil emulsion reverses the roles. E.g. butter. The type of emulsifiers used in milk retain all fats and lipids dispersed as nanoparticles in the aqueous medium, making milk easily miscible with water.Hence, water can be used to adulterate milk but not oil.
