Chemical Questions and Answers (Q&A)

Neurotransmitters are designated as the body's biological messengers. They are the molecules utilized by the nervous system to communicate messages between neurons, or from neurons to muscles. A neurotransmitter impacts a neuron in one of three ways, including excitatory, inhibitory, or modulatory. It transports, enhances, and balances signals between neurons, nerve, and other cells in the body.

These chemical messengers can affect a wide variety of both physical and phycological functions, including heart rate, sleep, appetite, mood, and fear. Endorphins are neuropeptides that are imperative to the body. One of their primary functions is to help the body handle pain. They are substances formed in the brain and the pituitary gland, which reduce painful sensations by binding to receptors in the nervous system.

By definition, a solution is a mixture in which a solute is disintegrated and equitably conveyed in a dissolvable.

Any evident solution is a homogeneous mixture. Numerous things that seem homogeneous at first glance are heterogeneous on the micro level. Milk for instance under tha microscope comprises of fat beads, protein particles and a fluid. Blood comprises of cells of a few sorts suspended in plasma.

Homogeneous mixtures have a similar sythesis all through.

For Instance: Sugar solution when the whole solution wind up lackluster, Salt water solution, Air without any clouds, Weakened wine, Vinegar solution.

Heterogeneous mixture have confined concentration i.e., their sythesis fluctuates from place to put.

For Instance: Cloudy air, Sand, Blood, River water, Oil-water mixture

Acclimations are metabolic adjustments of a living being, which may or may not necessitate the transcription of genes. Acclimations are always short term. Adaption is a heritable amendment in structure or function that serves to increase the probability of the survival of an organism.

Adaptions can be seen within the population level, and organisms tend to pass these genes to their offspring — adaption results in irreversible changes to the genome. In adaptation, population-level is measured. Acclimation is due to local environmental conditions and genetically determined response. In contrast, adjustment is irreversible. Adaptions are strategic, while acclimations are tactical.

Fertilizers and pesticides are needed for plants to grow and have good health. Fertilizers come in dry and liquid form, and they feed the plant with the nutrients. Fertilizers are available in organic and non-organic compounds. Pesticides are used on plants for removing, preventing, or controlling pests such as slugs, insects, fungal diseases, and snails. Pesticides thwart and control pests; however, pesticides also kill other bugs, such as ladybugs and bees.

Pesticides are a mixture of insecticides, fungicides, weed control materials, and rodent poisons. These pesticides act by destroying, inhibiting, and repelling harmful organisms. Fertilizers are used to boost the nutrient content of the soil. As plants mature, the nutrients in the soil become exhausted and are not restored by natural means. Fertilizers contain phosphorus, nitrogen, and potassium for their growth. Pesticides and fertilizers may cause harm to organisms.

There are some little differences between Vaseline and aquaphor. They are examples of comestic products and they have a lot of benefits for the body, particularly the human skin. A lot of medicated vaseline and aquaphor are very important in treating babies with rashes. The use of both vaseline and aquaphor can also prevent other skin related problems. However, there are some differences between vaseline and aquaphor. Vaseline is a 100 percent petroleum product.


It has been researched to have some chemical properties that help to speed up the healing process of a wound. Aquaphor, on the other hand, is not 100 percent petroleum products because it contains other ingredients like ceresin, panthenol, Lanolin and glycerin. Vaseline does not contain other ingredients because its 100 percent petrolatum. Vaseline is mostly used as skin lubricant to treat skin diseases, while aquaphor is not used as a lubricating agent in lotions.

The correct answer is D, compound. It is defined as a chemical substance, which has 2 or more bonded chemical elements. It has a fixed ratio that determines a composition. Chemical formulas are used to express the ratio of each element. There are four types of chemical compounds. The first is molecules, which are held together by covalent bonds. An example of a molecule is H20.

The second chemical compound is intemetallic, which are held together by metallic bonds. An example is Nitinol. The third is an ionic compound held by ionic bonds. An example if an ionic bond is sodium (Nat). The last and final compound is certain complexes, which are held by coordinate covalent bonds. An example is etnene.

Ethanol is pure aliphatic alcohol that is formed by replacing hydrogen with a hydroxyl group in ethane. The chemical formula of ethanol is C2H5OH. It can be used as fuel. Ethanol is mainly produced from corn or sugarcane. Compared to gasoline, ethanol is environmentally friendly as it supports complete combustion. However, ethanol less efficient, over time, it can cause severe damages to the engine.

Gasoline, on the other hand, is a fuel that consists of a mixture of refined petroleum hydrocarbons. It may contain up to as much as 500 hydrocarbons. Gasoline is mainly obtained from crude oil. A gallon of gas is known to produce one- third more energy than when using a gallon of ethanol. Gas undergoes incomplete combustion making it less environment-friendly compared to ethanol. It is not known to cause damage to the engine.
