The cortex, a layer of compressed, keratinized cells, surrounds the medulla, the central core of the hair, and the cuticle, an exterior layer of extremely hard, keratinized cells. A longitudinal cross-section of the hair follicle shows these layers.
What is the hair shaft?The visible portion of the hair that protrudes from the skin is called the shaft.
The hair root is located in the skin and extends into the skin's deeper layers. The hair follicle, which is encased in a sheath of connective tissue and skin, surrounds it and is joined to a sebaceous gland.
The portion of the hair shaft that is not attached to the follicle is largely exposed at the skin's surface.
The remainder of the hair, which is rooted in the follicle, is referred to as the hair root and is located underneath the skin's surface.
Therefore, the medulla is the innermost, soft core of the hair shaft.

Based on "Climate Change: An Overview,” what are the effects of global climate change? Check all that apply.
increasing temperatures in the Arctic
more-frequent forest fires
extinction of different plant species
extensive deforestation
increasing use of fossil fuels
rising sea levels
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:
Increasing temperatures in the ArcticMore-frequent forest firesExtinction of different plant and animal speciesRising sea levelsThese 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.

If a sugar compound has 11 oxygen atoms how many hydrogen atoms does it contain?
Using the stoichiometric formula of carbohydrates, a sugar compound follows the ratio of 1:2:1 for Carbon:Hydrogen:Oxygen. If a sugar compound has 11 Oxygen atoms, it would therefore contain 22 Hydrogen atoms.
Explanation:The subject of the question relates to the structure of a sugar compound. Considering the stoichiometric formula of carbohydrates, namely (CH₂O)n, where 'n' signifies the number of carbons in the molecule, a carbohydrate (sugar compound) is constructed in the 1:2:1 ratio of carbon to hydrogen to oxygen. If there are 11 oxygen atoms, this indicates that there are 22 hydrogen atoms, given the ratio.
An example of a carbohydrate that adheres to this ratio is glucose, which has a molecular formula of C6H12O6. This indicates that, on average, for one molecule of glucose, there are twice as many hydrogen atoms as there are oxygen atoms.
Therefore, in a sugar compound with 11 oxygen atoms, you would expect there to be twice as many hydrogen atoms, which amounts to 22 hydrogen atoms.

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.
What is the atomic number?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.
