Answer:

Empirical: OH

Molecular: \(H_{2} O_{2}\)

Explanation:

First of all, we are going to use the formula: mass = no. moles x Molar Mass And rearrange it to find No. moles: No. moles = mass/Molar Mass

Let's start with Hydrogen:

The given mass is 0.44g, and hydrogen's molar mass is 1.01, therefore the number of moles is: 0.44/1.01 = 0.4356

Now we do the same for Oxygen:

Given mass = 6.92, Molar mass of Oxygen = 16.00, No. Moles = 6.92/16.00 = 0.4325

Now we identify the smaller one (Oxygen as 0.4325 < 0.4356) and we divide both values by that number:

0.4325/0.4325 = 1

0.4356/0.4325 = 1.01

We round both to the nearest 0.2 or 0.25 (depending on what you're taught), and we get: 1 and 1.

This means that the empirical formula has one of each: OH

Now to find the molecular formula we find the relative mass of OH and divide the given mass by that:

M(OH) = 16.00+1.01 = 17.01

34.00/17.01 = 2

We now multiply both by this number to get:

\(H_{2} O_{2}\)

Answer: The chemical origin of life refers to the conditions that might have existed and therefore promoted the first replicating life forms. It considers the physical and chemical reactions that could have led to early replicator molecules. All life is composed mainly of the four macromolecule building blocks: carbohydrates, lipids, proteins, and nucleic acids. The interactions of different polymers of these basic molecule types make up the majority of life's structure and function.

Natural selection needs the existence of four factors: reproduction, inheritance, variation in organism fitness, and variation in individual traits among population members.

Natural selection happens by accident if they are fulfilled, natural selection will occur if three criteria are satisfied, according to Darwin's theory. These conditions, compete with each other for survival, variation, and inheritance.

As per some, these conditions are both necessary and sufficient for natural selection to actually occur.

Therefore, traits inherited, and selection pressure is the three conditions for natural selection to actually occur and result in evolutionary change.

To determine the identity of the unknown analgesic with three spots having rf values of 0.1, 0.3, and 0.5, we need to compare the rf values of the unknown spots with those of known substances. We can do this by performing thin-layer chromatography (TLC) with a set of standard compounds.

TLC is a technique used to separate and identify components in a mixture. In this case, we would first prepare a TLC plate with the same solvent system used to develop the unknown spots. We would then spot the plate with known analgesic compounds with known rf values.

Once the plate is developed, we can compare the positions of the known and unknown spots. If the rf values of the unknown spots match those of a particular standard compound, we can conclude that the unknown analgesic is that compound.

For example, if the unknown spots have rf values of 0.1, 0.3, and 0.5, and we find that a known compound with an rf value of 0.3 matches one of the unknown spots, we can conclude that the unknown analgesic is that compound.

In summary, to identify the unknown analgesic with three spots having rf values of 0.1, 0.3, and 0.5, we need to perform TLC with known analgesic compounds and compare the rf values of the unknown spots with those of the known compounds.

The true statement regarding deamination is that deamination of cytosine results in uracil, option B is correct.

Deamination is a chemical process that involves the removal of an amino group \((-NH_2)\) from a nucleotide base. In the case of cytosine, deamination results in the conversion of cytosine to uracil. This process occurs spontaneously and can lead to mutations in DNA. When uracil is present in DNA, it is recognized as an error during DNA replication or repair.

The normal complementary base for uracil in DNA is adenine, so during replication or repair, uracil is typically replaced with adenine. If not corrected, the presence of uracil in DNA can lead to genetic instability and potentially harmful mutations. Therefore, deamination of cytosine to uracil is an important process in DNA damage and repair mechanisms, option B is correct.

In proteins, the folding of the unit on itself is referred to as its tertiary structure.

Protein folding is the process by which a protein structure assumes its three-dimensional form. A polypeptide sequence in its nascent state is unstable and often incapable of fulfilling its biological function. The process of protein folding is a vital process that is critical for protein function and evolution.A protein's native state is determined by its amino acid sequence and by how it folds in vivo. In a complex series of events, some spontaneous and others assisted by protein folding chaperones, newly synthesized polypeptides undergo folding, a process that often occurs on a sub-second timescale in vivo.

The primary, secondary, tertiary, and quaternary structures are the four levels of protein organization.

Primary structure: The primary structure is the order of amino acids in a protein.

Secondary structure: The secondary structure is the initial folding or coiling of the polypeptide into alpha-helices, beta-sheets, or other structural motifs.

Tertiary structure: The three-dimensional structure of an entire polypeptide, which is determined by interactions between secondary structural motifs.

Quaternary structure: The interaction of two or more tertiary subunits to form a functional protein is referred to as quaternary structure, which is the highest level of protein structure.

a. Life support, food, water, air etc.

b. Physical factors, climate, Rain fall

c. Biological factors: microorganisms, toxins, Biological waste,

d. Psycho-social and economic e.g. Crowding, income level, access to health care

e. Chemical factors: industrial wastes, agricultural wastes, air pollution, etc

C. Life style (Behaviour): is an action that has a specific frequency, duration, and purpose, whether conscious or unconscious. It is associated with practice. It is what we do and how we act.

The immune system's destruction of self-tissues is a hallmark of autoimmune illnesses. The inability to eliminate b and t lymphocytes that respond to self-antigens is the fundamental cause of many illnesses. Here option A is the correct answer.

Autoimmune disorders occur when the body's immune system mistakenly attacks its own healthy cells and tissues, leading to chronic inflammation and tissue damage. The underlying basis of these disorders is a failure in the self-tolerance mechanisms, which are responsible for distinguishing between self and non-self molecules.

The immune system is equipped with various mechanisms to identify and eliminate cells that pose a threat to the body. During the development of immune cells, a process called central tolerance occurs, which involves the deletion of B and T cells that recognize self-antigens. This process ensures that the immune system does not mount an attack against its own tissues.

However, in autoimmune disorders, this process fails, and self-reactive B and T cells escape elimination, leading to the production of autoantibodies and the activation of immune cells that attack the body's own tissues.
