Abnormalities in calcium regulation are most likely to arise from problems thyroid gland.

An endocrine gland found in vertebrates is the thyroid, or thyroid gland. It is located in the neck and has two connected lobes in humans. A thin tissue band known as the thyroid isthmus connects the lower two thirds of the lobes. The thyroid is situated beneath the Adam's apple in the front of the neck. The thyroid follicle, which is spherical and lined with follicular cells (thyrocytes) and occasionally parafollicular cells that surround a lumen containing colloid, is the functional unit of the thyroid gland under a microscope.

Three hormones are secreted by the thyroid gland: triiodothyronine (T3), thyroxine (T4), and calcitonin, a peptide hormone. The production of protein, as well as growth and development in children, are all influenced by thyroid hormones.

Enzymes are proteins capable of recognizing and binding to very specific small molecules, such as glucose. The tertiary structure of protein leads to this binding specificity. The correct answer is option(c).

A protein is a naturally occurring, highly complex molecule composed of amino acid residues joined by peptide bonds. Proteins, the building blocks of various essential biological components like enzymes, hormones, and antibodies, are present in all living organisms. This configuration of amino acids is referred to as the basic structure of a polypeptide chain.

The term "tertiary structure" refers to the overall spatial organization of a protein's polypeptide chain in three dimensions. Internal hydrophobic interactions between nonpolar amino acid side chains and outer polar hydrophilic hydrogen and ionic bond interactions stabilize it most frequently.

A mutation has developed that has deleted a gene responsible for the formation of vesicles at the trans end of the Golgi apparatus. as a result lysosomes will not be produced.

Lysosomes are formed due to the fusion of vesicles from the trans end of the Golgi. Addresses sequences are recognized by the sorting system and it directs them to produce lysosomes.

So the production of lysosomes will be stopped if a mutation deleted a gene responsible for the formation of vesicles at the trans end of the Golgi apparatus.

Dendritic cells are required for T lymphocyte activation. As a result, it is critical that dendritic cells acquire all conceivable threats.

Dendritic cells :

Dendritic cells (DCs) are antigen-presenting cells of the mammalian immune system (also known as accessory cells). Their primary job is to digest antigen material and display it on the cell surface to immune system T cells. They serve as liaisons between the innate and adaptive immune systems. Dendritic cells are found in tissues that come into touch with the outside world, such as the skin (where a particular dendritic cell type known as the Langerhans cell exists) and the inner linings of the nose, lungs, stomach, and intestines. They can also be detected in the blood in an immature condition.

Auditory stimulation is processed in the Temporal lobes that is present on the underside of the cerebrum and plays a great role in the processing of auditory information.

On the underside of the cerebrum, right below the temples, is the temporal lobe, which is situated below the parietal and occipital lobes. It is crucial for processing auditory information, including giving meaning to aural signals.

The brain’s temporal lobe, which connects the two hemispheres, aids in processing sensory information such as pain and auditory impulses.

The superior temporal gyrus in the temporal lobe houses the primary auditory cortex (A1), which has a precise tonotopic map because it gets point-to-point input from the ventral division of the medial geniculate complex. The temporal lobe is also in charge of memory, learning, and auditory perception.

The levels of the ecological pyramid in order from the least to the greatest amount of biomass: -

1. Pyramid of Number

The population (total number of people) present at each trophic level is represented visually by the first pyramid, which is a pyramid of numbers.

Depending on the number of organisms, this type of pyramid can take either an upright or an inverted shape.

The number of creatures in an upright pyramid of numbers often decreases from bottom to top. The plants (often the grasses) at the base of the pyramid are what typically cause this to happen in grassland and pond environments. The pyramid's higher tiers also contain the consumers.

2. Pyramid of Biomass

In a given trophic level, biomass is defined as the amount of living material present in an organism multiplied by the total number of organisms present. In simpler terms, it refers to the food that will be consumed by the following trophic level.

Even before the proposal of continental drift, paleontologists recognized that some sort of land connection was needed to account for the identical fossil organisms found on multiple continents. The following hypotheses were not proposed:

(a) A chain of island stepping stones or a transoceanic land bridge  

(c) Floating debris used as rafts and sea level rising

(d) A large boat

Continental drift is the theory that the Earth's continents have shifted over time relative to each other, therefore seeming to have "drifted" across the sea bed. The theory of continental drift has been absorbed into the science of plate tectonics, which investigates the activity of the continents as they pivot on plates of the Earth's lithosphere.

The replacement of one amino acid with another is least likely to affect the protein’s function is B. An amino acid with a C=O group that is replaced by an amino acid with O-H group.

The amino acid with a methyl (CH3) group as its side chain is called alanine. Three C-H bonds are present in this side chain. Nonpolar and hydrophilic describe alanine. Hydrophilic amino acids, which can form hydrogen bonds with water, are all charged amino acids. Interactions with the extracellular and intracellular environment will be disrupted if a hydrophilic amino acid is substituted with a hydrophobic amino acid.

Amino acids that are hydrophobic are typically incorporated into the membrane. The hydrophobic core will be disrupted and protein function will be impacted if a hydrophobic amino acid is substituted with a hydrophilic amino acid.

Therefore, the replacement of one amino acid with another is least likely to affect the protein’s function is an amino acid with a C=O group that is replaced by an amino acid with O-H group.
