Exercise induces the release of three hormones: adrenaline, endorphins, and cortisol.

Adrenaline is a stress hormone released by the adrenal glands in response to physical or psychological stressors that increases heart rate, glucose levels, breathing rate, muscle strength and cognitive function.

Endorphins are neurotransmitters triggered by strenuous activity that provide a sense of euphoria, helping to reduce pain perception and improve mood.

Finally, cortisol is a steroid hormone released as part of the body’s fight-or-flight response which helps raise blood sugar levels while also aiding in tissue repair following exercise or physical activity.

Thusly, these hormones play an important role in not only maintaining homeostasis during physical activity but also providing relaxation after exercise has concluded.

Question1: Amino acids. Option B.

Question 2: Phosphorus. Option D.

Proteins are a form of macromolecules. They are polymers made from amino acids that are linked together by peptide bonds. Amino acids are themselves made from elements such as carbon, hydrogen, oxygen, and nitrogen.

When proteins are broken down, they break down into their component amino acids.

Following these principles, if the antibiotics are working effectively by breaking down cell wall proteins, the researchers should find traces of amino acids in the phagocytes.

Also, if the monomers are examined, the only element that should be absent should be phosphorus.

In case of an isotonic contraction, cross-bridges must generate sufficient tension to exceed the load to be moved.

An isotonic contraction is a type of muscle contraction that takes place when the tension or force in the muscle remains consistent while the length of the muscle is altered. An isotonic contraction can be concentric or eccentric.

A concentric contraction is a type of an isotonic muscle contraction during which the muscles shorten or contract while producing tension or force, overpowering resistance.

An eccentric contraction is another kind of isotonic muscle contraction during which the muscles lengthen while the muscle is still producing tension or force. However, the resistance exceeds the resulting force in magnitude.

Plants require essential elements for growth. These can be divided into two types. The soil supplies relatively large amounts of carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), potassium (K), sulfur (S), calcium (Ca) and, magnesium (Mg). And thus, these are called macronutrients. boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), nickel (Ni), and zinc (Zn). In relatively small amounts, the plant also requires iron (Fe), manganese (Mn), boron (B), molybdenum (Mo), copper (Cu), zinc (Zn), chlorine (Cl), and cobalt (Co), which are called

Boron deficiency leads to the stout axis: true

Boron is involved in vegetative and reproductive cell growth. Deficiency of this nutrient is common. It is caused due to low Boron content in water or fertilizer or due to increased uptake of calcium which inhibits boron uptake. Boron deficiency leads to stunted and distorted growing tips. Therefore, the statement is correct.

B. Every mineral element that is present in a cell is needed by the cell: false

Minerals absorbed by the plants are generally utilized for their growth and development. But that is not true for all elements. Plants also absorb minerals like lead, silicon, uranium, silver, gold, etc that are not essential for growth. This phenomenon is mostly seen in plants growing near the mining areas. Thus the statement is false

C. Nitrogen is a nutrient mineral, is highly immobile in the plants: false

Minerals like nitrogen, phosphorus, potassium, magnesium, chlorine, zinc, and molybdenum are mobile nutrients in plants whereas calcium, sulfur, iron, boron, and copper are immobile nutrients. Thus the statement is false.

D. It is very easy to establish the essentiality of micronutrients because they are required only in trace quantities: false

As plants require certain nutrients in trace quantities, it is difficult to establish their essentiality. Thus the statement is false.

Note: Plants take up essential elements from the soil through their roots and from the air through their leaves. The root, especially the root hair, is the essential organ for the uptake of nutrients. Thus, any alteration in the structure and architecture of the root can affect the rate of nutrient uptake. Nutrient uptake by plants is by simple diffusion, facilitated diffusion, or active transport.

During the course of a successful desensitization process, the patient's antibodies will change from an IgE isotype to an IgG4 isotype, option E is correct.

Desensitization is a therapeutic approach used to reduce or eliminate hypersensitivity reactions, such as allergies. In allergic individuals, IgE antibodies are produced in response to allergens, leading to the release of inflammatory substances upon subsequent exposure to the allergen. Desensitization involves controlled and gradually increasing exposure to the allergen, which helps modulate the immune response.

Through the desensitization process, the immune system undergoes a shift in antibody production. Initially, IgE antibodies dominate the allergic response. However, successful desensitization promotes a change in antibody production, with IgG4 antibodies becoming more prevalent. IgG4 antibodies are considered to have an inhibitory effect on allergic reactions by blocking the binding of allergens to IgE antibodies and reducing the release of inflammatory mediators, option E is correct.

The chromosome theory of inheritance is directly related to Mendel's findings in genetics. In Mendel's experiments with pea plants, he observed the inheritance of traits from one generation to the next. He postulated that traits were passed down in discrete units, which he called "factors" (now known as genes).

Later, scientists discovered that these genes were located on chromosomes, which are the structures that carry genetic information in cells. The chromosome theory of inheritance states that genes are located on chromosomes and are passed down from parents to offspring during reproduction. This theory is consistent with Mendel's findings and provides a mechanism for how traits are inherited from one generation to the next.

In summary, the chromosome theory of inheritance helps to explain the physical basis of Mendel's observations and provides a framework for understanding how genetic information is passed down from generation to generation.

Explanation:

In order to stay organized and fit within the tiny confines of a cell, DNA (Deoxyribonucleic acid) is packaged into structures called chromosomes. Chromosomes are thread-like structures made up of DNA and proteins. They are found inside the nucleus of a cell.

The packaging of DNA into chromosomes helps to protect the DNA from damage and allows for efficient storage and transmission of genetic information. It also plays a crucial role in regulating gene expression. The process of packaging DNA into chromosomes involves several steps. First, DNA molecules wrap around proteins called histones to form nucleosomes.

Nucleosomes are the basic building blocks of chromatin, which is the complex of DNA and proteins. Multiple nucleosomes are then further compacted and folded, forming higher-order structures. During cell division, chromosomes condense even further and become visible under a microscope. This condensed form allows for easier separation and distribution of DNA during cell division.

Overall, the packaging of DNA into chromosomes is essential for the proper functioning of cells. It ensures that DNA is protected, organized, and able to be replicated and transmitted accurately during cell division.

The statement that best describes the cells and their functions in the humoral arm of the immune system is antibodies are primarily responsible for protection, option C is correct.

In the humoral arm of the immune system, B lymphocytes, also known as B cells, play a central role. These cells are responsible for producing and releasing antibodies, which are specialized proteins that target and neutralize pathogens such as bacteria and viruses. Antibodies recognize specific antigens on the surface of pathogens and mark them for destruction by other components of the immune system.

B cells undergo differentiation and develop into subpopulations, including plasma cells that secrete antibodies and memory B cells that provide long-term immunity upon subsequent exposure to the same pathogen.
