Answer:
See the answer below
Explanation:
The addition of acid to a DNA causes a change in its absorbance because acids tend to destroy the covalent bonds that hold the base pairs in DNA together.
In other words, acids, especially at high concentrations, denatures DNA. Denatured DNAs exhibit hyperchromic reaction, that is, they show increased absorbance as a result of less interaction between the bases.
Answer:
b. in vessel elements only, after turgor loss point through air-seeding across pit membranes
Explanation:
As in humans, embolism can happen in plants. In the case of plants, embolism occurs only in the elements of the vessel, after the point of loss of the turgor through the propagation of air through the membranes of the pits, in other words, the embolism occurs when there is air filling the empty spaces of the xylem (element of vase), creating air bubbles.
These air bubbles block the xylem's work in transporting water from the root to the other parts of the plants, that is, it reduces the plant's ability to absorb water from the soil, thus preventing the plant from carrying out not only photosynthesis, but numerous metabolic processes essential for your body to survive.
Answer: seen below
Explanation:
Deoxyribonucleic acid (DNA) synthesis is the biological process by which DNA molecule is created. In the cell, each of the two strands of the DNA molecule acts as a template for the synthesis of a complementary strand. This strands are separated during replication (DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule). DNA polymerase synthesizes the new strands by adding nucleotides that complement each (template) strand.
Deoxyribonucleic acid (DNA) synthesis is continuous because extension of a single ribonucleic acid (RNA) primer occurs without interruption into the replication fork as it continues to open to the right as seen on the diagram below. On the upper lagging strand which is the discontinuous synthesis, here synthesis is discontinuous, since new RNA primers must be added as opening of the replication fork continues to expose new template.
b. chloride and bicarbonate
c. calcium and phosphate
d. sodium and phosphate
Answer:
Sodium and potassium.
Explanation:
Aldosterone hormone is produced by the adrenal cortex (zona glomerulosa ) cells of the kidney. This is the main mineralocorticoid and the steroidal hormone.
Aldosterone is mainly involved in the regulation of sodium and potassium ions. The sodium ions are reabsorbed and potassium ions is secreted by the influence of aldosterone hormone.
Thus, the correct answer is option (a).
The eqation which reporesent Photosynthesis is6CO2 + 6H2O ® C6H12O6 + 6O2
Photosynthesis is the process by which green plants manufacture their food(in form of sugar) using carbon dioxide and water in the presence of sunlight. This is possible because of the presence of chlorophyll which creates a medium to absorb the sun's energy. The Light energy formed then converts water and carbon dioxide into oxygen and sugars.
The chemical equation to represent the process is as follows
6CO2 + 6H2O ------> C6H12O6 + 6O2.
sunlight
Here, six molecules of carbon dioxide and six molecules of water reacts in the presence of light energy captured by chlorophyll from the sun to form sugar and six molecules of oxygen.

sulfites
propionic acid
benzoic acid
Answer:
Sulfites are thechemical food preservatives which used in the wine industry but may cause asthmatic reactions in some individuals .
Explanation:
A chemical food preservative is a chemical species which are added to a product such as the beverages , food , drugs , paints , wood etc , to prevent the process of degradation by microbes .
Sulfite is also an example of chemical food preservatives , sulfites helps the food from turning brown , in the presence of air .
Apart from helping the food from degrading , it too have same life - threatening symptoms for some people suffering from asthma .
Symptoms are - breathing difficulty , stomach cramps , tightness in the chest area , diarrhea .
Sulfites are used as a food preservatives in , wine , dried fruits , frozen potato , certain jams .
Answer and explanation:
If excessive amounts of acetoacetic acid were to build up in the body, the pH of the blood would decrease, because the blood would become more acidic.
Acetoacetic acid is produced because of lipolysis (fat degradation) or because of the breakdown of amino acids. This is a normal biochemical process, but it can lead to serious issues when the levels of acetoacetic acid rise more than they should.
Patients with Diabetes Mellitus have a deficiency in their insulin production. Insulin is the only hormone that can make glucose enter the cells, which is important because glucose (sugar) is processed inside the cells to produce ATP (a molecule high in energy).
Patients with Diabetes can't get the glucose inside their cells, so the blood sugar levels rise in the blood (hyperglycemia). Since the body still needs ATP to function properly, energy requirements are being met via the degradation of fat and amino acids - which generates acetoacetic acid. If this continues, the pH drops and Diabetic Ketoacidosis occurs. This condition is life-threatening.
