Answer and Explanation:
Petroleum and coal are fossil fuels. The degradation of the earliest plants forms them. These dead plants started to pile up and form peat. Then the pressure and heat from various geological procedures convert peat into coal. Coal is a combustible rock which contains 50% carbon. Anthracite, Lignite and bituminous are the types of coal, and the formation of coal depends upon the quantity of hydrogen, oxygen and carbon. Petroleum exists naturally in liquid form and formed by decomposed organic matter. Fossil fuels can be refined into usable substances. Gasoline, tar, lubricants and many other products are obtained from petroleum. There are two steps, which required to form fuel from atmospheric carbon dioxide. In first step carbon dioxide is converted into carbon monoxide. In the second step, carbon monoxide combines with hydrogen to form hydrocarbon fuels. The formation of fuel is a natural process when animals respire carbon dioxide release in the atmosphere.

Which of the following statements DOES NOT accurately describe the experimental design used by Fred Griffith?
A.The type of bacteria injected into the mouse was the independent variable in his experiment. B.The injection of the live rough bacteria into the mouse is a control because it was used as a standard of comparison for other experimental setups.
C.The dependent variable in the experiment was the health of the mouse after injection.
Answer:
The correct answer is B. It is false that the injection of the live rough bacteria into the mouse is a control because it was used as a standard of comparison for other experimental setups.
Explanation:
The experiment conducted by Frederick Griffith in 1928 was one of the first experiments to show that bacteria could transfer genetic information.
Griffith used two slightly different pneumococcal strains in his experiment. One of them was harmless to the mice, while the other was not. Using each strain separately, the logical thing happened: the mice died with the fatal strain, and nothing happened with the harmless.
Then, Griffith killed the deadly strain, and mixed both strains, introducing them into the mice. After this, the mice died, which allowed us to verify that the bacteria can transfer genetic material even after dying, through the transformation process.

when the total number of gas molecules in solution remains constant, the solution is in
When the total number of gas molecules in a solution remains constant, the solution is in a state of dynamic equilibrium. In this state, the rate of gas molecules leaving the solution is equal to the rate of gas molecules entering the solution, resulting in a stable concentration of gas in the solution.
Dynamic equilibrium occurs when a balance is reached between the physical processes of evaporation and condensation.
At the molecular level, gas molecules are constantly moving and colliding with the liquid surface.
Some gas molecules gain enough energy to escape from the liquid phase and enter the gas phase, while some gas molecules in the gas phase collide with the liquid surface and reenter the liquid phase.
The establishment of dynamic equilibrium depends on factors such as temperature, pressure, and the nature of the solvent and solute. These factors influence the vapor pressure of the gas and its solubility in the solvent.
When equilibrium is reached, the concentration of gas molecules in the solution remains constant over time, as the rates of evaporation and condensation become equal.
Overall, dynamic equilibrium is a state of balance in which the solution maintains a constant concentration of gas molecules, even though individual molecules are constantly moving between the gas and liquid phases.

In the genetic cross in between two F1 hybrid pea plants for spherical seeds will yield what percent spherical sedded plants in the f2 generation?
In the genetic cross between two F1 hybrid pea plants for spherical seeds, the F2 generation is expected to yield 75% spherical seeded plants and 25% wrinkled seeded plants.
This is because the F1 generation is heterozygous for the spherical seed trait (Ss), and when crossed, the offspring have a 1:2:1 genotypic ratio of SS:Ss:ss. The SS and Ss genotypes both result in spherical seeds, while the ss genotype results in wrinkled seeds.
Therefore, 3 out of 4 possible genotypes in the F2 generation will produce spherical seeds, resulting in a 75% chance of spherical seeded plants.

Explain the limitation binomial nominclature (15 marks)
Answer:
- Binomial nomenclature is a widely accepted naming system, which is used in the naming of living things. Multiple native names make it extraordinarily tough to establish an organism globally and maintain an observation of the variety of species. Thus, it creates quite a lot of confusion. To eliminate this confusion, a normal protocol came up. According to it, every organism would have one scientific title which might be utilized by everybody to establish an organism.
What is binomial nomenclature?
Binomial Nomenclature follows a universally accepted naming system, which is used to provide a scientific name to a known organism.
Binomial Nomenclature also known as the binary nomenclature.
It uses two-terms during the nomenclature of a specie (plants, animals, and living organisms) that is why it called two-term naming system.
The scientific name of an organism or binomial nomenclature consists of two words, such as the generic epithet and describes the genus and the specific epithet and refers to the species of the organism.
Both of this term is written in italic and the genus name is capitalized.
Binomial nomenclature was given by Swedish botanist and physician Carl Linnaeus. He also called the founder of modern taxonomy.
Carl Linnaeus described and classified thousands of species of plants and animals in his book Systema Naturae.In this technique, there are particular guidelines that are followed while naming organisms. This normal algorithm is relevant to plants and animals whereas giving them distinctive names inside a given system.There are two worldwide codes such as the International Code of Botanical Nomenclature (ICBN) deal with the biological nomenclature for plants and the International Code of Zoological Nomenclature (ICZN) deal with the biological nomenclature of animals.
These two codes agreed upon by all of the biologists over the world for the naming protocol. These codes ensure that every organism will get a selected identity and that identity is globally recognized.
Summary of the limitation binomial nominclature:
- Some of the main drawbacks of binomial nomenclature are: If two or more names are actually in use in compliance with the priority rule, the appropriate name will be used first and the other names will end up being synonyms because authenticity is synonymous with the senior.

N a culture of bacteria, a sample is taken at 10:00am and contains 1000 cells per ml. A second sample at 8:00pm has 10,000 cells per ml. What is the generation time ?
The generation time of the bacteria in the following culture is approximately 3.01 hours.
To determine the generation time of bacteria, we can use the formula:
Generation time (t) = (Time elapsed (T) / Number of generations (n))
In this case, we have a time difference of 10 hours between the two samples.
To calculate the number of generations, we can use the formula:
Number of generations (n) = log(N₂ / N₁) / log(2)
Where N₂ is the final cell count (10,000 cells/ml) and N₁ is the initial cell count (1,000 cells/ml).
Plugging in the values, we get:
Number of generations (n) = log(10,000 / 1,000) / log(2) ≈ 3.32
Now, we can calculate the generation time:
Generation time (t) = Time elapsed (T) / Number of generations (n)
Generation time (t) = 10 hours / 3.32 ≈ 3.01 hours
Therefore, the generation time of the bacteria in this culture is approximately 3.01 hours.

The leading strand in DNA replication is synthesized continuously by DNA polymerase in the 5' to 3' direction from the origin of replication.
Explanation:During DNA replication, the leading strand is built continuously in the 5' to 3' direction by DNA polymerase. DNA polymerase adds deoxyribonucleotide (dNTP) to the 3' end of the DNA. The replication begins at a specific point in the DNA molecule called the origin of replication. Here, the DNA helix is separated by the enzyme helicase, which forms a structure known as the replication fork. In this structure, on the leading strand, the DNA polymerase is moving in the same direction as the replication fork, allowing it to read the original DNA strand and synthesize the new strand continuously.

Residual parent material refers to the *weathered rock* and *soil* that remains in its place of origin, while *transported parent material* is material that has been carried and deposited by natural agents such as water, wind, or glaciers.
The impact of these different types of parent material on *soil formation* can be significant. Residual parent material tends to contribute to the formation of soils with characteristics similar to the parent rock. The weathering process breaks down the rock into smaller particles, allowing for the development of soil horizons and the release of minerals that influence soil fertility. In contrast, transported parent material can introduce a diverse range of materials to a given area, leading to variations in soil composition, texture, and fertility. The transportation process can mix different types of sediment, resulting in the formation of heterogeneous soils with varying properties.
Residual parent material is the rock and soil that is still located in its original location and is weathered. Transported parent material is material that is carried and deposited by natural agents such as water, wind, or glaciers. The effect of these different types of parent material on soil formation can be significant.
Residual parent material usually contributes to the development of soils with qualities similar to the parent rock. The breakdown of rock into smaller particles through weathering enables the formation of soil horizons and the release of minerals that influence soil fertility.
The physical and chemical characteristics of soils derived from this form of parent material are often similar and homogeneous, allowing for predictable fertility and properties. Transported parent material, on the other hand, can introduce a diverse range of materials to a given area, resulting in variations in soil composition, texture, and fertility.
The transportation process can blend different types of sediment, resulting in the formation of heterogeneous soils with different characteristics. Transported parent material can also be exposed to weathering processes, altering its original composition and resulting in soils with varying degrees of fertility.
While transported parent material can increase the diversity of soil properties in an area, it can also make it difficult to predict soil characteristics, particularly in areas where different types of sediment have been deposited. The relationship between parent material and soil development is complex, with both the initial characteristics of the material and the surrounding environment influencing soil properties.
In general, residual parent material contributes to the development of homogeneous soils with predictable properties, while transported parent material can result in more diverse and heterogeneous soils.
