Answer:

Scientists use a general process known as Scientific Inquiry to ask and answer questions about nature.

Explanation:

Scientific inquiry is best defined as a fixed process that follows the steps of question, hypothesis, and investigation, gathering evidence, and communicating results.

This process is the most widely used process by scientists around the world. It involves investing a given subject in a logical way to find evidence that supports the answer.

It is based on measurable evidence to specify the reasoning.

The general process that scientists use to gather information and answer questions is called the scientific method.

The scientific process begins with making observations or noticing something interesting or unusual about the natural world. Observations can be made through direct observation, measurements, or experiments.

Based on the observations made, scientists formulate a specific and testable question, often referred to as a research question or hypothesis. The question should be clear and focused, guiding the subsequent steps of the scientific method.

A hypothesis is a tentative explanation or prediction for the observed phenomenon. It is an educated guess that can be tested through experimentation or further observation. The hypothesis should be specific and falsifiable, meaning it can be proven wrong through evidence.

The correct option is Oscar determines the mineral content of rock core samples at different depths in Earth’s crust

We know that Earth layers are divided into different distances from its core. They vary from depth to depth inside the earths core. The layers of earth are basically formed by the types of rocks inside it. The very internal shape of earth contains molten rocks and the very outer layer called the crust has hard rocks so we can say that the types of rocks is responsible for the formation of earth's layers.

The Earth is made up of several layers, which are situated at different depths from the core. The method to show differences among Earth's layers is:

Oscar determines the mineral content of rock core samples at different depths in Earth’s layers.

The Earth is made up of several layers, namely, crust, core, and mantle. These layers are situated at different depths and exhibit different properties. The layers are generally distinguished based on the composition of rock materials and their depth from the core. For instance, the crust of the Earth is hard, whereas the internal layers consist of molten rocks. Thus, different types of rocks shape the Earth layers.

Reasons for incorrect answers:

Therefore, the Oscar method determining the mineral content of rock core samples at different depths can show differences in the Earth's layers.

We are well aware that there are two stages of photosynthesis:

Calvin cycle or light-independent reactions:

This comprise the process during which carbon dioxide enters into the leaves of plants and passes through series of steps to form sugar or food. This process depends on the supply of ATP, (the ATP that is formed previously during light dependent reactions).

Now there are three stages of Calvin cycle:

During the process of carbon fixation CO2 combines with a 5-carbon compound called RuBP or ribulose-1,5-bisphosphate which results in the synthesis of a 6-carbon compound that splits up in to 2 three carbon compounds called phosphoglyceric acid (3-PGA).

Here out focus will be the process of Reduction.

Reduction is the second stage of Calvin cycle during which phosphoglyceric acid (3-PGA) is converted to glyceraldehyde-3-phosphate (G3P) that is a sugar. During the process of reduction, energy in the form of ATP and NADPH  are used for the conversion of 3-PGA to G3P. As 3-PGA is reduced to G3P, therefore this process is known as reduction.

After reduction, a series of reactions occur that lead to the synthesis of glucose but since focus of our question was reduction, so you can see more details of the process in attached figure.

A chromosome is a Deoxyribonucleic acid molecule with part or all of the genetic material of an organism.

Answer:

Chromosome is the compact form of genetic material(DNA) present in the nucleus of a cell. These chromosomes are a combination of proteins and DNA. These chromosomes carry our hereditary material in the form of genes.

Each chromosomes carry many genes which are transferred to the next generation. Each chromosome divides into the S- phase and they become compact during the mitosis phase.  

Chromosomes can be seen under the microscope in the metaphase stage of cell cycle. 23 pairs of chromosomes are present in each cell out of which 22 are autosomes and 23rd is the sex chromosome.  

These sex chromosomes is different in both male and female because females have two X chromosomes and male have one X and one Y chromosome as sex chromosome.

The answer is that the criteria of classification change with the improved understanding of organisms around us. During the time of Aristotle, not much was known about the living organisms. So, he classified them as he observed. Plants were classified into herbs, shrubs and trees; very much like what’s taught to a second grade student. Animals as Enaima and Anaima based on the presence or absence of RBCs. After him, Carolus Linnaeus tried his hand over classification. He came up with the 2 kingdom classification: Plants and Animals. He considered only a set of morphological and physiological criteria to decide the kingdom to which an organism belongs. It includes presence of cell wall, mode of nutrition, contractile vacuole, locomotion and others. Based on these criteria, he included widely differing organisms into a single kingdom, for example, fungi, bacteria, algae, and higher plants were included into plant kingdom just because they have cell wall as a common aspect. Then came, Ernst Haeckel, who came with a third kingdom of Protista to include unicellular organisms. Copeland gave a 4 kingdom classification segregating unicellular organisms into 2 separate kingdoms based on their nuclear structure. R.H. Whittaker came next introducing the most accepted 5 kingdom classification system. You should understand one thing that man’s knowledge of classifying organisms improved with the improving technologies available to him, which he exploited to very effective extent. Carl Woese gave the 6 kingdom classification and 3 domain system based on the 16S rRNA sequence.

Our understanding of organisms around us is improving day by day and the system of classification will also change further in pace with the improvement in technology.

Modern classification systems have evolved from Linnaeus' original taxonomy to include genetic and biochemical criteria, introducing new categories and a three-domain system. These revisions allow for a more accurate representation of evolutionary relationships among organisms.

Differences Between Modern and Linnaean Classification Systems

The modern classification system has evolved significantly from the taxonomy first developed by Carl Linnaeus in the 1700s. The Linnaean system grouped organisms based on morphological traits such as the number of legs or shape of leaves. However, with the discovery of many new species and advances in our understanding of evolutionary relationships and genetics, modifications were necessary. Modern classification not only includes physical characteristics but also considers biochemical and genetic similarities and differences, leading to a more detailed and evolutionary-based taxonomy.

Linnaeus' work was foundational to modern biology, introducing the system of binomial nomenclature which gives each species a two-part name signifying the genus and species. Yet, it was limited by the knowledge of his time and therefore did not account for all the complexities discovered since. With the incorporation of molecular biology, new categories such as the subphylum, superfamily, and domain were added to better reflect the relationships among life forms. Furthermore, the modern system includes a three-domain system which classifies life into Bacteria, Archaea, and Eukaryota as opposed to Linnaeus' simpler kingdoms.

The changes to Linnaean taxonomy ultimately allow for a classification system that is adaptable and potentially more accurate, accommodating new scientific discoveries and perspectives on the nature of life.

The process when cell divides is refereed to as mitosis.when a cell has copied all its DNA then the cell normally divides.

Before the mitosis occurs the cell has to replicate its DNA making a copy of each chromosome this phase is referred to as inter-phase while the cell division is referred to as mitosis

SUMMARY

A cell has to replicate its DNA making a copy of each  chromosome,called sister chromatids

Before cell division occurs, a cell goes through stages of the cell cycle which are the G1 phase (growth and carrying out functions), the S phase (DNA replication), and the G2 phase (further growth and preparation for division). These stages are crucial to ensure that each resulting cell after division has a complete set of genetic material.

Before cell division can occur, a cell must pass through several stages. Collectively, these stages are referred to as the cell cycle. The first stage is the G1 phase, where the cell grows and carries out its functions. Next is the S phase, during which DNA replication occurs. Here, the cell makes a copy of its genetic material in preparation for division. This is followed by the G2 phase, where the cell continues to grow and prepares for division. Lastly, the cell enters the M phase, where cell division, specifically mitosis, actually occurs.

The processes that occur before cell division, particularly DNA replication, are crucial because they ensure that each daughter cell will have a complete set of genetic material after the cell divides.

To determine which two classes of arthropods are the least related, one must consult a phylogenetic tree. Without it, we infer from general arthropod taxonomy that classes from distant subphyla, like Hexapoda (insects) and Chelicerata (spiders), would be the least related.

To answer which two classes of arthropods are the least related, it's essential to refer to a phylogenetic tree illustrating the taxonomic relationships among various arthropod groups. In the absence of a specific phylogenetic tree provided for the question, we use general knowledge of arthropod taxonomy to infer relationships. Phylum Arthropoda is divided into subphyla such as Hexapoda (insects and relatives), Myriapoda (millipedes, centipedes, and relatives), Crustacea (crabs, lobsters, crayfish, isopods, barnacles, and some zooplankton), and Chelicerata (horseshoe crabs, arachnids, scorpions, and daddy longlegs).

The two classes of arthropods that would be least related according to this classification are likely to come from distant subphyla, for example, an insect from Hexapoda and a spider from Chelicerata. However, without a specific phylogenetic tree, it is not possible to determine exactly which two classes are the least related, and this answer would only be inferred from the broader taxonomic categories.

You could say DNA and RNA but I would use DNA to be more specific

Answer:

DNA and RNA

Explanation:

Nucleic acids (DNA and RNA) are found in both viruses and in living single-celled organisms, such as protozoa and bacteria. They are responsible for heredity and are the basis for building proteins that are essential to the body.

Both are made up of subunits - the nucleotides. Each nucleotide is formed by a 5-carbon sugar (deoxyribose, in DNA and ribose in RNA), a radical of phosphoric acid (phosphate) and a cyclic compound with nitrogen (the nitrogenous base). There are five types of nitrogenous bases: adenine (A), guanine (G), cytosine (C), thymine (T) and uracil (U). These molecules are responsible for the formation of genes.

when light is absorbed by one of the pigments in Photosystem II, energy is transferred thereby exciting an electron to high energy level. This excited electron is passed on to the acceptor molecule and gets replaced with an electron that comes up while splitting of water molecules.
