Identify and explain three major issues that cut across psychology

An atom of the most common isotope of neutral potassium has a nucleus composed of 19 protons as well as 19 electrons and  21 neutrons.

An atom's atomic number is determined by the total number of protons it contains. Both the number of neutrons and the number of electrons present inside an atom have no relation to the atomic number.

Because isotopes have the property that they have the same number of protons but varying amounts of neutrons, an atom of neutral potassium's most prevalent isotope has a nucleus made up of 19 protons, 19 electrons, and 21 neutrons.

Thus, The most prevalent isotope of neutral potassium has atoms with nuclei made up of 19 protons, 19 electrons, and 21 neutrons.

Explanation:

Proteins are made from amino acid chains that are linked together by peptide bonds, then folded into specific structures. This process is determined by the genetic code, and even slight changes can significantly affect protein function. Protein synthesis is a quick and efficient process that is fundamental to life.

Protein Synthesis from Amino Acids

A chain of amino acids transforms into a protein through a series of biological processes which include the formation of peptide bonds, resulting in polypeptides, and subsequent folding into specific shapes. This process begins when amino acids are joined together through a dehydration reaction that forms a peptide bond between the carboxyl group of one amino acid and the amino group of another, releasing water. Chains with two amino acids are termed dipeptides, with three as tripeptides, and generally, chains with about 50 or more amino acids are known as proteins or polypeptides.

The unique sequence of amino acids in a protein is encoded by genes, with even a minor change potentially leading to significant differences in protein function. Following synthesis, proteins often undergo additional processing, which may include folding and modification, before assuming their final function. The genetic code is a universal system that translates the information in DNA and RNA into the sequence of amino acids in proteins.

The entire protein synthesis is relatively quick, with amino acids being added to the polypeptide chain at a rate of several per second, meaning that small proteins can be assembled in under a minute. Such efficiency is essential for the vast array of proteins required by living organisms to sustain life.

Final answer:

The effects of global climate change include increasing temperatures in the Arctic, more-frequent forest fires, extinction of different plant species, and rising sea levels.

Explanation:

The effects of global climate change include:

Increasing temperatures in the Arctic: Global warming is causing the Arctic to warm at a faster rate than the rest of the world, leading to the melting of ice and loss of habitat for polar bears and other cold-adapted species.

More-frequent forest fires: Rising temperatures and drier conditions increase the likelihood of forest fires, which can have devastating impacts on ecosystems and human communities.

Extinction of different plant species: Climate change can disrupt ecosystems and lead to the extinction of plant species that cannot adapt to the changing conditions.

Rising sea levels: Melting glaciers and ice sheets contribute to rising sea levels, which can result in coastal flooding and erosion, threatening coastal communities and ecosystems.

Final answer:

The effects of global climate change include increasing Arctic temperatures, more frequent forest fires, species extinction, and rising sea levels. These changes result from human activities like burning fossil fuels and contribute to the worsening of climatic conditions.

Explanation:

Based on “Climate Change: An Overview,” the effects of global climate change include several critical environmental and societal changes. Here are some of the main effects that apply:

These effects lead to the retreat of glaciers, the expansion of deserts, shifts in natural habitats towards the poles, a loss of biodiversity, and a variety of human challenges such as health problems and the displacement of populations. Global climate change is not caused by the increasing use of fossil fuels but is certainly exacerbated by it. Extensive deforestation is an example of a human activity that contributes to climate change but it is not a direct result of climate change itself.

Endocrinology is the study of how hormones function. Hormones are chemical messengers that travel through the bloodstream, influencing various cellular activities by binding to their target cells' receptors. The study of these hormones' production, regulation, and function is the main focus of Endocrinology.

The study of how hormones function is called Endocrinology. Hormones are chemical messengers produced by the endocrine system, which travel throughout the body in the bloodstream, and their function is to control or regulate specific physiological processes. They influence a variety of cellular activities such as reproduction, growth and development, metabolism, fluid, and electrolyte balance, among other functions.

These hormones function by binding to receptors on their target cells, triggering a chain of events that leads to the cell's response. Various hormones have different actions; for instance, some hormones can directly enter the cell, interact with DNA and regulate gene transcription, while others bind to the cell surface receptors and trigger a signaling pathway.

The detailed study of how these hormones work, including their production, regulation, and function, is the main focus of Endocrinology. Hence, understanding these hormonal functions can aid in comprehending how the human body's various systems maintain homeostasis and adapt to changes in internal or external environmental conditions.

Final answer:

The lens of the eye is chiefly responsible for its focusing ability. It adjusts its power to focus images on the retina, with the fovea being the point of greatest acuity.

Explanation:

The lens is responsible for most of the eye's ability to focus images. The cornea and lens form a system that acts as a single thin lens, allowing for a real image to be projected onto the light-sensitive retina. The lens has the capability to change its power by adjusting the radius of curvature, enabling the eye to focus on objects at various distances. This power adjustment is crucial because the retina is at a fixed distance from the lens.

For the highest sharpness in vision, the center of the image falls on the fovea, an area with the densest concentration of light receptors. The eye's pupil, a variable opening, and its ability to chemically adapt allow it to detect a vast range of light intensities, safeguarding the eye against damage.
