When two heterozygous purple pea plants are crossed, the genotypes are 1 PP, 2 Pp, and 1 pp. Three offspring will be purple, and one will be white.

A genetic cross involves two parents: ,one is the maternal parent, and the other is the paternal parent. The genetic cross is explained with the help of the punnett square.

The example is the purple petal in the pea plant. The purple Petal colour is dominant to white Petal colour. P is dominant to p. Hence PP and Pp will produce purple petal colour in case of complete dominance. pp will produce white Petal color 

When two heterozygous parents are crossed, each parent will produce two gametes, such as P and p. As a result, two types of phenotypes will be produced in cases of complete dominance, such as three purple and one white offspring. The cross is explained below.

Hence, if the heterozygous purple pea plants are crossed, then the genotypes would be 1 PP, 2 Pp, and 1 pp. The ratio is 1:2:1 of PP :Pp: pp.

The concentration of lac gene products can be increased or decreased based on different events, including inducing gene expression, increasing the amount of the gene, degradation, and deactivation of the promoter.

One way to increase the concentration of lac gene products is by inducing gene expression with an inducer such as IPTG. This inducer binds to the lac repressor protein, preventing it from attaching to the operator region of the gene and blocking transcription. As a result, transcription is allowed to proceed and the gene products are synthesized.

Another way to increase the concentration of lac gene products is by increasing the amount of the gene itself. This can be done through the process of transformation, where a foreign gene is inserted into a cell. The foreign gene is integrated into the cell's genome and its products are expressed as normal.

On the other hand, the concentration of lac gene products can be decreased through degradation or through deactivation of the promoter. Degradation occurs when the gene products are broken down by proteases, while deactivation of the promoter occurs when a repressor protein binds to it and blocks transcription.

In conclusion, different events can either increase or decrease the concentration of lac gene products, including inducing gene expression, increasing the amount of the gene, degradation, and deactivation of the promoter.

Explanation:

Sickle cell anemia, cystic fibrosis, and hemophilia are some of the hereditary diseases that occur because of changes in the genetic make of an organism.

Hereditary diseases usually referred to as inherited diseases or genetic disorders, are a group of genetic diseases that are brought on by changes in a person's genetic makeup (DNA). These changes are caused by mutation. This occurs when the normal bases in the DNA is replaced with the faulty base or mismatched base.  

Then, these illnesses are passed down from one generation to the next, or in other words, they are inherited from one set of parents to another. For example, sickle cell anemia, cystic fibrosis, and hemophilia are some examples of hereditary diseases.  

Because sickle hemoglobin requires two copies of the gene to be present, sickle cell anemia is referred to as a recessive condition. They must get one from each parent, which code for abnormal hemoglobin.

The term defined as deformation divided by original length is strain. Option B is correct.

Strain is a term used in materials science and mechanics to describe the amount of deformation or elongation a material undergoes when subjected to external forces or stress. It is calculated by dividing the change in length of a material by its original length.

Strain is represented by the Greek letter epsilon (ε) and is typically expressed as a dimensionless quantity or as a percentage. The formula to calculate strain is:

Strain (ε) = Change in length / Original length

For example, if a material with an original length of 10 centimeters elongates to 11 centimeters when subjected to stress, the strain would be:

Strain (ε) = (11 cm - 10 cm) / 10 cm = 0.1 or 10%

Stress, on the other hand, is the force applied to a material per unit area. It represents the internal resistance of a material to deformation. Stress is often measured in units such as pascals (Pa) or pounds per square inch (psi).

Strength refers to the ability of a material to withstand an applied force without failure. It is a measure of the material's capacity to resist deformation, breaking, or permanent damage under stress.

Elasticity is the property of a material to regain its original shape and size after being deformed. It represents the ability of a material to stretch under stress and return to its original form when the stress is removed.

Calculation: Strain = Change in length / Original length

In conclusion, the term defined as deformation divided by original length is strain. Strain is a measure of the amount of deformation or elongation a material undergoes when subjected to external forces or stress. Understanding the concepts of strain, stress, strength, and elasticity is essential in materials science and engineering to analyze and predict the behavior of materials under different conditions and loads.

D. Stroke volume is the amount of blood pumped by the left ventricle with each beat.

The heart pumps blood to the body through a series of contractions and relaxations. Stroke volume refers to the amount of blood that is ejected from the left ventricle of the heart with each contraction, also known as a heartbeat.

The left ventricle is the heart's main pumping chamber, responsible for delivering oxygenated blood to the body's organs and tissues. When the heart contracts, it pushes blood out of the left ventricle and into the aorta, which distributes it to the rest of the body.

Stroke volume is determined by a number of factors, including the size of the left ventricle, the strength of the heart muscle, and the pressure within the ventricle. A healthy heart typically pumps between 60 and 100 milliliters of blood per beat, depending on a person's age, size, and overall health.

The solubility of SO2 gas in water increases as the temperature increases from 10°C to 30°C at standard pressure.

Solubility is a property of a substance that defines the maximum amount of that substance that can dissolve in a solvent (usually water) at a given temperature and pressure. The solubility of a gas in water is generally increased as the temperature increases because an increase in temperature will increase the kinetic energy of the gas molecules, allowing them to escape from the liquid surface into the gas phase more readily. This means that the concentration of gas in the solution will increase as the temperature increases, resulting in an increase in solubility.

In the case of SO2 gas, as the temperature increases from 10°C to 30°C at standard pressure, the solubility of SO2 in water will also increase. This is because the solubility of a gas is directly proportional to the gas pressure above the solution, and temperature has a direct effect on gas pressure. An increase in temperature will increase the gas pressure above the solution, resulting in an increase in the solubility of the gas.

Protein metabolism is difficult because nitrogenous wastes like ammonia and urea build up. This is the answer. A long answer is given below.

Protein metabolism is one of the most complex processes carried out by living organisms because it includes the breakdown of amino acids and their conversion into other amino acids, sugars, fats, and other metabolic intermediates. The products of protein metabolism, which include nitrogenous wastes like ammonia and urea, are potentially toxic and must be removed from the body. The liver is responsible for metabolizing the nitrogenous wastes produced by protein metabolism, which are excreted by the kidneys.

If the liver or kidneys are damaged or functioning poorly, the buildup of nitrogenous wastes in the bloodstream can lead to serious health issues. Additionally, the energy required for protein metabolism is higher than that required for other types of metabolism, as proteins contain 9 kcal/gram of energy, compared to 4 kcal/gram for carbohydrates and fats. Therefore, the body must expend more energy to break down and metabolize protein. Finally, ATP cannot be made from protein, as it can from carbohydrates and fats, which are more efficient energy sources. As a result, the body must use protein to make glucose or fatty acids, which can then be used to produce ATP.

Hereditary spherocytosis results in normocytic, normochromic anemia in the peripheral smear because of the increased destruction of the red blood cells (RBCs) that are spherical rather than the normal biconcave shape.

Hereditary spherocytosis (HS) is an inherited disorder of the RBCs, which is caused by mutations in genes encoding proteins of the RBC membrane and cytoskeleton. The membrane and cytoskeleton protein deficiencies result in a decrease in the surface-to-volume ratio of the RBCs, leading to their sphere-shaped morphology. Additionally, this sphere-shaped morphology renders the cells more vulnerable to shear stress, decreasing their flexibility and making them less deformable than normal RBCs.

Consequently, HS is associated with splenomegaly, hemolytic anemia, and hyperbilirubinemia, which can lead to bilirubin gallstones and neonatal jaundice. In HS, the sphere-shaped RBCs are not as flexible as the normal biconcave-shaped RBCs. Thus, they become trapped in the smaller blood vessels of the spleen and destroyed, leading to hemolytic anemia. The removal of these sphere-shaped RBCs results in the formation of reticulocytosis, the premature release of immature RBCs, which leads to normocytic, normochromic anemia in the peripheral smear.

In conclusion, HS is an inherited disorder of the RBCs, caused by mutations in genes encoding proteins of the RBC membrane and cytoskeleton. The sphere-shaped RBCs are not as flexible as normal RBCs, and they become trapped in the smaller blood vessels of the spleen and destroyed, leading to hemolytic anemia.
