In the chemical reaction described in the passage, the products are water (\(H2O\)) and silicon tetrafluoride gas (\(SiF4\)).

When hydrofluoric acid (HF) comes into contact with silica (\(SiO2\)), a reaction occurs where the substances combine and transform into these products.

The reaction can be represented as follows:

\(SiO2\) + 4HF → \(SiF4\)+ 2\(H2O\)

In this equation, the silica (\(SiO2\)) and hydrofluoric acid (HF) are the reactants, and they undergo a chemical reaction. As a result of this reaction, water (\(H2O\)) and silicon tetrafluoride gas (\(SiF4\)) are produced.

Water (\(H2O\)) is a compound composed of hydrogen and oxygen atoms. It is a liquid at room temperature and is essential for various biological and chemical processes.

Silicon tetrafluoride gas (\(SiF4\)) is a compound made up of silicon and fluorine atoms. It is a colorless gas and is commonly used in various industrial applications, such as the production of silicon-based materials and as a source of fluoride ions.

After the water and silicon tetrafluoride gas are removed, the silicon sheet is left without the unwanted silica coating, and it can be further processed into microchips through various manufacturing steps.

In the nephron's Bowman's capsule regions, such alterations do not take place. Our kidney's nephrons carry out three primary functions: filtration, reabsorption, and secretion. Hence (c) is the correct option.

The process of tubular secretion, which is the opposite of reabsorption, involves the movement of substances from peritubular capillaries to the renal tubular lumen. Active transport and passive diffusion are the main causes of this secretion. Only a small number of typically waste-related substances are secreted. The kidneys' generated urine travels through the ureters, gathers in the bladder, and is finally expelled by the urethra.

The excretory system is a passive biological system that removes excess, unnecessary materials from an organism's body fluids in order to help maintain internal chemical homeostasis and prevent body damage.

Organs of the human excretory system enable the elimination of nitrogenous wastes from the body. The kidney, ureter, urinary bladder, and urethra are the primary excretory organs. Blood is filtered through the kidneys, and the result is urine.

Sir Francis Galton was the first to show that the traits of the human mind are distributed normally.

Thus, Galton, a well-known polymath in the late 19th century, studied human intellect and mental characteristics in great detail. He gathered information from a huge number of people on a variety of cognitive skills, including sensory acuity, memory, and response speed.

Galton discovered through statistical research that these characteristics showed a bell-shaped curve when plotted on a graph, suggesting a normal distribution. The idea that many human mental traits, including IQ, tend to cluster around the average with fewer individuals at the extremes was made possible by this seminal study.

The false statement about genetic drift as an evolutionary factor is the main process that produces adaptation.

Genetic drift is a change in gene frequency in a small population due to random events. Ideally, a population should be large so that genetic drift does not affect its gene pool. In general, genetic drift is caused by catastrophes and the formation of new colonies by a small number of individuals. Major disasters such as volcanic eruptions and tsunamis can reduce population size drastically.

As a result, the genetic structure of the small population that survives may not be representative of the original population structure, a situation commonly referred to as the bottleneck effect. With the loss of most of the alleles from the gene pool, the bottleneck effect and the resulting genetic drift will reduce the genetic diversity within a population. The bottleneck effect may explain why populations of cheetahs show so little genetic variation.

To determine the number of mice that will be infected next week and in three weeks, we need to consider the probabilities of mice overcoming the virus and becoming infected. So according to given information 240 mice are will be infected in next week and 224 mice are will be infected in 3 weeks.

Next Week:

Currently, 300 mice are infected. Since there is a 90% chance that an infected mouse will overcome the virus, we can calculate the number of infected mice that will remain next week as follows:

Remaining infected mice = 300 * (1 - 0.9) = 30 mice

At the same time, there is a 30% probability that a non-infected mouse will become infected. We have 700 non-infected mice, so the number of mice that will be newly infected next week is:

Newly infected mice = 700 * 0.3 = 210 mice

Therefore, the total number of infected mice next week will be:

Total infected mice = Remaining infected mice + Newly infected mice = 30 + 210 = 240 mice

In 3 Weeks:

To calculate the number of mice infected in three weeks, we can repeat the same process.

Remaining infected mice after one week = 240 * (1 - 0.9) = 24 mice

Newly infected mice in the second week = 676 * 0.3 = 202.8 ≈ 203 mice

Remaining infected mice after two weeks = 203 * (1 - 0.9) ≈ 20.3 ≈ 20 mice

Newly infected mice in the third week = 680 * 0.3 = 204 mice

Therefore, the total number of infected mice in three weeks will be:

Total infected mice = Remaining infected mice after two weeks + Newly infected mice in the third week = 20 + 204 = 224 mice.

Agglutination is a process in which particles or cells clump together due to the interaction between specific antibodies and antigens.

The type of blood sample that shows agglutination on a slide depends on the type of antibody being used in the test. For example, if blood sample anti-D is used, it will agglutinate red blood cells that have the D antigen on their surface. This indicates that the person's blood type is Rh-positive. If blood sample anti-A is used, it will agglutinate red blood cells that have the A antigen on their surface, indicating that the person's blood type is A. Similarly, blood sample anti-B will agglutinate red blood cells that have the B antigen on their surface, indicating that the person's blood type is B. Blood sample O does not have any antigens on their surface, so it will not agglutinate with any of these antibodies.

ATP or Adenosine Triphosphate is the primary source of energy for most cellular processes including muscle contraction. ATP is synthesized through several energy sources during muscle contraction.

The sources of energy that synthesize ATP for muscle contraction are as follows:Glycolysis: This process occurs in the cytoplasm and it converts glucose or glycogen into pyruvate. The energy released in this process is used to synthesize ATP. The net gain from glycolysis is two ATP molecules. Krebs cycle or Citric acid cycle: This cycle occurs in the mitochondria and it generates ATP by oxidizing acetyl-CoA to carbon dioxide. The total yield of ATP from one glucose molecule is 36 or 38 ATP molecules depending on the source of glucose. Electron transport chain: This is the final stage of oxidative metabolism that occurs in the inner membrane of mitochondria. During this process, electrons are transferred from one molecule to another and this generates a proton gradient. This gradient is used by ATP synthase to synthesize ATP from ADP and inorganic phosphate (Pi). The yield of ATP from one glucose molecule in this process is 28 or 32 ATP molecules depending on the source of glucose.
