Explanation:

Answer:a). base pairing rules

Explanation: A DNA is a double stranded helix in which the two DNA strands are antiparallel and complementary to each other. Watson and Crick developed the base pairing rules that adenine pairs with thymine and cytosine pairs with guanine. The complementary strand are not the same in base sequence and composition instead anywhere adenine is found in one strand, thymine is found in the other strand and anywhere cytosine is found in one strand, guanine occurs in the other strand.

Answer:

Good oral health and diet

fruits. vegetables. lean sources of protein such as lean beef, skinless poultry and fish; dry beans, peas and other legumes. low-fat and fat-free dairy foods.

Explanation:

Final answer:

Dietary modifications such as pureeing or chopping foods can help those with oral cavity problems eat more easily. Maintaining oral health is essential for overall well-being, as dental issues can lead to malnutrition and exacerbate other health conditions.

Explanation:

To accommodate those with oral cavity problems, dietary changes such as modifying food textures can significantly enhance the ability to eat comfortably. Solid foods can be pureed, ground, or chopped, which simplifies the process of chewing and swallowing, and minimizes the risk of aspiration. Oral health professionals such as speech therapists, dentists, and dietitians often collaborate to define suitable diets for individuals with dysphagia—a condition of impaired swallowing.

When dental issues prevent efficient chewing, the use of dentures or specially prepared softened foods like purees can be helpful. If there are difficulties with swallowing, increasing fluid intake during meals is advised. Consultation with healthcare professionals is important whenever chewing or swallowing issues arise.

Furthermore, a healthy oral environment is crucial for general well-being. Poor oral health can result in difficulty eating, malnutrition, and may exacerbate other health conditions, particularly in the elderly and those with serious illnesses. Therefore, ensuring a healthy mouth is essential not only for ease of food intake but also for maintaining overall health.

The bacteria which had mutation became resistant to the antibiotic and survived and keeps on increasing, promoting natural selection.

Explanation:

The bacteria rapidly divide, the chances of mutation in the gene increases manifold.

The strains of bacteria causing tuberculosis and staph infection got mutated at DNA level such that they became resistant to antibiotics when tested those susceptible did not survive. These mutations were not harmful to bacteria and the resultant bacteria survived.

These bacteria which survived and proliferated as the environment was in their favour.

Thus, Darwin's Theory of Natural Selection is acceptable here as it says if a mutation is occurring towards the increase in population, they will be selected ones.

Final answer:

The malonic acid most likely affected the mitochondria in the muscle cells, leading to a decrease in ATP production. The ATP production fell to near zero but not actually zero because other metabolic pathways like glycolysis can still generate small amounts of ATP in the absence of oxygen. A testable hypothesis could be that malonic acid inhibits the enzymes involved in aerobic respiration, leading to a decrease in ATP production. If malonic acid is added to an anaerobic organism, it is unlikely to have a significant effect on ATP production.

Explanation:

The organelles in the muscle cells most likely affected by the malonic acid are the mitochondria. Mitochondria are responsible for producing adenosine triphosphate (ATP), which is the main energy-carrying molecule in cells. The malonic acid likely disrupted the normal functioning of the mitochondria, leading to a decrease in ATP production.

The ATP production fell to near zero but not actually zero because there may have still been a small amount of ATP being produced through other metabolic pathways in the cells, such as glycolysis. Glycolysis is an anaerobic process that can generate small amounts of ATP even in the absence of oxygen.

A testable hypothesis concerning respiration in cells treated with malonic acid could be that the malonic acid inhibits the enzymes involved in aerobic respiration, leading to a decrease in ATP production. This hypothesis could be tested by comparing the ATP production in cells treated with malonic acid to cells not treated with malonic acid.

If malonic acid is added to an anaerobic organism, it is likely to have little to no effect on ATP production. Anaerobic organisms rely primarily on glycolysis for ATP production, which does not require oxygen or functioning mitochondria. Therefore, the malonic acid would not significantly impact ATP production in an anaerobic organism.

A) Mutation is the original source of variations for plants and other organisms  which develops differences among their respective species

Explanation:

Genetic variation leads to the natural differences between each individual and among individuals of a species. The main cause for this variation is due to alleles that cause variations in the composition of genes or the DNA sequences.  

A mutation is a genetic variation which leads to the creation of a new allele in a species population. Each variation in the DNA sequence leads to an allele formation and each allele leads to a difference in character or trait between individuals since they are the alternate version of the original genes.  

Although genetic variations could be brought about by crossing over, random fertilization, or independent assortment; mutation is the original source because it provides the basic raw material for all the evolutionary changes.

Answer:

The product of the DNA synthesis reaction is that, from a DNA molecule, two identical molecules of this nucleic acid are obtained.

Explanation:

The DNA replication process involves a series of events that result in obtaining two DNA molecules with the same sequence of nitrogen bases relative to the original.  This must occur previous to the process of cell division, so that each cell daughter possesses the same genetic information.

For this process to occur the double DNA chain must be unrolled and, from each of the simple chains a complementary chain is formed, by adding complementary nitrogen bases: adenine with thymine and cytosine with guanine. DNA synthesis is facilitated by the action of the enzyme DNA polymerase.

DNA synthesis is called semi-conservative, as each molecule obtained in the process has a simple chain, coming from the original molecule, and a new synthesized chain.

Final answer:

The product of DNA synthesis is two identical DNA molecules, comprised of one original strand and one new strand. This replication process ensures genetic information is preserved.

Explanation:

The product of a DNA synthesis reaction is two identical DNA molecules, each consisting of one original and one newly synthesized strand. This process, known as replication, occurs within the nucleus of a cell during the S phase of the cell cycle. Enzymes such as DNA polymerase play a pivotal role in this process, 'unzipping' the original double helix to use as templates for synthesis. Free deoxynucleoside triphosphates (dNTPs) are aligned opposite their complementary bases on each template strand, and DNA polymerase catalyzes the addition of these nucleotides to the 3' end of the growing chain. Thus, each daughter DNA molecule is an accurate copy of the parent DNA, ensuring genetic information is preserved during cell division.

One condition that must be met for a population to be in genetic equilibrium is the absence of mutations. Other conditions include no migration, a very large population, random mating, and no natural selection as stated by the Hardy-Weinberg theorem.

For a population to be in genetic equilibrium, certain conditions must be met. One of these conditions is no mutation, meaning there should be no change in the DNA sequence. Alongside this, other essential conditions include no migration (no individuals entering or leaving the population), a very large population size to minimize the impact of genetic drift, random mating among individuals without any selective pressures, and no natural selection, where all genotypes have equal probabilities of survival and reproduction.

The Hardy-Weinberg theorem suggests that maintaining these conditions will result in allele and genotype frequencies that do not change over time, indicating no evolutionary forces at play. However, it is recognized that these conditions are rarely, if ever, fully met in natural populations due to the influence of evolutionary processes such as drift, mutation, migration, and selection.

Answer:

a. Anaphase 2

b. Metaphase 1

c. Telophase 1

d. Prophase 1

e. Telophase 2

Explanation:

Following is a summary of the events of meiosis:

Interphase:

Prepares the cell for division. Duplication of DNA, duplication of centrioles occurs and the cell grows in size. At this stage the cell is diploid (2n).

Prophase 1:

First stage of Meiosis 1.The centrioles move to the poles of the cell, the nuclear membrane disintegrates, homologous chromosomes pair up (in the form of tetrad), form a chiasmata and then exchange segments of chromosomes with each other. This process is called crossing over.

Metaphase 1:

Involves the arrangement of the crossed over, homologous chromosomes on the metaphase plate which is sort of like a web of spindle fibers that originates from the centrioles.

Anaphase 1:

The tetrads arranged on the metaphase plate are pulled apart by the spindle fibers. This is the result of tension that build up in the spindle fibers as they grow towards opposite poles.

Telophase 1:

The last stage of meiosis 1. Involves the arrival of the chromosomes at the poles, the nuclear membrane starts to form and the chromosomes start decondensing. Telophase 1 yields 2 daughter cells with half the number of chromosomes as that in the parent cell.

Meiosis 2:

Meiosis 2 is exactly similar to mitosis. The only difference is that the haploid cells entering meiosis 2 do not duplicate their DNA. Meiosis 2 just involves the separation of the sister chromatids of homologous chromosomes.

The steps of meiosis shown in the diagrams are: Prophase I, Metaphase I, Anaphase I, Telophase I, Cytokinesis I, Prophase II, Metaphase II, Anaphase II, Telophase II, Cytokinesis II.

A swan neck flask that prevented air from getting in was the control in Pasteur's experiment. Therefore, option (C) is correct.

The experiment was designed to test the hypothesis of spontaneous generation, which proposed that living organisms could arise spontaneously from non-living matter. To test this, Pasteur used swan-necked flasks that allowed air to enter but prevented microorganisms from getting in. The flasks containing the nutrient broth were boiled to sterilize the contents and the curved neck of the flasks prevented dust and microorganisms from entering.

The control group in this experiment was the flask with the nutrient broth that was not exposed to the external environment. This flask was used as a comparison to the experimental group, which was a flask with the nutrient broth that was exposed to the external environment. By comparing the growth of microorganisms in the two groups, Pasteur was able to demonstrate that microorganisms do not arise spontaneously from non-living matter, but rather come from pre-existing microorganisms.

BY comparing modern (today's) atmospheric CO2 level with historical (past) data in the graph.

Explanation:

Completed the test

By contrasting the current atmospheric CO2 levels with the historical data shown in the graph, scientists might utilise these data to determine if a new approach to the issue of global warming is effective.

This would enable them to ascertain if the new remedy is having an impact on CO2 levels in the atmosphere. Scientists may determine if the new solution is having an effect on the quantity of CO2 in the atmosphere by comparing the levels of atmospheric CO2 at now with those in the graph.

Scientists might also use fresh ice cores to collect new information about previous atmospheric CO2 levels in order to better assess the efficacy of the new approach. This would enable them to contrast present atmospheric CO2 levels with earlier ones.

The new approach was put into practise. If the new remedy is having an impact on the level of atmospheric CO2, scientists can tell by comparing the data from the fresh ice core samples with the data from the graph. Finally, researchers may contrast current atmospheric CO2 levels with information from other planets.

This would enable them to establish whether the new remedy is affecting the level of atmospheric CO2 globally. Scientists may evaluate if the new solution is having a beneficial impact on the quantity of atmospheric CO2 on a global scale by comparing the data from Earth with the data from another planet.

Hardy-Weinberg equilibrium is not common in natural populations due to various evolutionary forces such as mutation, migration, selection, genetic drift, and non-random mating.

In natural populations, it is rare for populations to be in Hardy-Weinberg equilibrium. Hardy-Weinberg equilibrium is a concept that describes an idealized population where the allele frequencies do not change from generation to generation. However, in reality, various factors such as mutation, migration, selection, genetic drift, and non-random mating can all disrupt the equilibrium.

For example, genetic drift is a random change in allele frequencies due to chance events. Small populations are more susceptible to genetic drift, and as natural populations are often small, they are more likely to experience random changes in allele frequencies.

Overall, Hardy-Weinberg equilibrium provides a useful theoretical framework, but it is not commonly observed in natural populations due to the presence of various evolutionary forces.

Answer:

the system of nomenclature in which two terms are used to denote a species of living organism, the first one indicating the genus and the second the specific epithet.

Explanation:

Final answer:

Binomial nomenclature is a system of naming species with a two-part Latin name consisting of the genus name and species identifier. Developed by Carolus Linnaeus, it provides a unique and universally recognized name for each species, avoiding the confusion of common names and facilitating clear communication among scientists worldwide.

Explanation:

Binomial nomenclature is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. This two-part name is called a binomial (meaning "two names" in Latin). The first part of the name identifies the genus to which the organism belongs, while the second part identifies the species within the genus. For example, the scientific name for humans is Homo sapiens, where Homo is the genus and sapiens is the species identifier.

The Swedish naturalist Carolus Linnaeus is credited with developing binomial nomenclature in the 18th century, which revolutionized the way scientists named and classified organisms. It enabled clearer and more consistent communication among scientists from different regions and languages. When printed, the genus name is always capitalized and the species name is always lowercase, and both are italicized, for example, Felis catus for the domestic cat.

The convention of binomial nomenclature not only mitigates the confusion caused by local and common names but also provides each species with a unique and universally recognized name. This universal nomenclature facilitates accurate communication and information sharing among biologists and researchers across the globe.
