Nonrenewable resources are used much more prevalently today despite knowing that they pollute and will run out in the future. why then are we not using more renewable resources?
We are not using more renewable resources because we have been using fossil fuels since the 18th century and renewable resources are comparatively new. Also, we have limited knowledge about them, so it will take time to change our mindset toward renewable resources.
Based on exhaustibility, there are mainly two types of resources, renewable resources, and non-renewable resources.
Renewable resources are those resources that are replenished while non-renewable resources are those resources that are not replenished.
The non-renewable resources take millions of years to form and once exhausted they cannot be made more.
Examples of renewable resources are solar energy, wind energy, geothermal energy, etc. while examples of non-renewable resources are fossil fuels like coal and petroleum, metals, etc.
Despite the fact that the supply of non-renewable resources like coal and petroleum is limited and they also cause pollution, the use of them is rampant around the world.
The use of fossil fuels is widespread because we have been using them since the 18th century and the use of renewable resources is a very recent phenomenon.
Also, a major hurdle for using renewable resources is the upgrading of current technology to harness these resources.
The newer technologies are generally more expensive to employ, for example, the solar cells used for storing solar energy are made up of elements like silicon, silver, and gallium which are expensive.

Different chemical elements will create a different scattering of absorption lines in the spectrum of visible light. We understand the interaction of an atom with light, and because of this we can predict where the lines should be and verify this in a lab. This process is called?
A. Astronomy
b.Nucleosynthesis
c.Spectroscopy
d. Star formation
Chemists research the interactions of many types of electromagnetic radiation with atoms and molecules. The term "spectroscopy" refers to this interaction.
Because various elements have varying quantities of protons and varied numbers and configurations of electrons, they also have different spectra. The variations in spectra are a result of the energy that atoms absorb or emit as their electrons shift between different energy levels. A transition from ground state or lower-energy excited state to a greater excited state can occur as a result of an atom's ability to absorb light of a certain energy. As a result, an element's emission spectrum is converted into an absorption spectrum, which contains dark lines aligned with brilliant lines. Chemists research the interactions of many types of electromagnetic radiation with atoms and molecules. The term "spectroscopy" refers to this interaction. Ordinary stars like the Sun have absorption lines in their spectra because some of the continuous light emanating from the hot, dense interior is absorbed by the fragile outer layers of the stellar atmosphere, known as the photosphere.Learn more about spectroscopy here:

What would happen to both acid-fast and non acid-fast cells if no heat was used in the staining procedure?
When both acid-fast and non-acid-fast cells if no heat was used in the staining procedure the cell wall becomes hydrophobic and impermeable. It happens because most stains and chemicals in aqueous material are in the absence of heat due to the waxy, destructive structure. It's possible that we neglected to heat the solution or decolored it excessively.
Acid fast stains are used to differentiate acid-fast organisms such as mycobacteria. Mycolic acids make up a large portion of the cell walls of acid-fast bacteria. Nonacid-fast bacteria will stain blue/green with the Kinyoun stain, while acid-fast bacteria will stain red. Non-acid fast bacteria are those that decolorize and lose their carbol fuchsin red color.
The primary difference between acid-fast and nonacid-fast bacteria is that acid-fast bacteria resist decolorizing by acid after receiving a stain whereas non-acid-fast bacteria are readily decolorized by acid after staining.

Human dna has two types of chromosomes. what are these two types, and how do they differ from each other? would you expect both types to appear in the dna you extracted?
Yes, Human DNA have two types of chromosomes that are Autosome and Allosomes/ Heterosomes
Human Chromosomes are Found:
Before cell division, chromosomes are widely distributed and challenging to find. The chromosomes may be observed clearly during cell division, photographed, and their morphology, size, and shape analyzed. Autosomes and sex chromosomes are two groups of chromosomal types. Below is an explanation of these types:
The autosomes
The structures that house the genetic material are called autosomes. They do not include details about reproduction and sex identification. The male and female species of humans are the same in both sexes. In humans, there are 46 (2n) chromosomes. There are 44 pairs of autosomes among the 46 chromosomes, and they each provide data on the phenotypic traits.
Heterosomes and allosomes
The size, shape, and behavior of the sex chromosomes known as allosomes differ from those of autosomes. In humans, there are two allosomes. The sperm can include either the X or Y chromosome, and the X chromosomes are present in the ovum. These chromosomes aid in determining the progeny's sex. If both the mother and the father contributed an X chromosome, the child would be female (XX). A male child is born if the offspring inherits one X chromosome and one Y chromosome from the parents (XY). Simply said, the father's donation of an X or Y chromosome aids in determining the gender of the child.

The p in ph stand for the german word potenz, witch means "power" or "potential." the h represnts hygrogen ions. how are these related to the definition of ph
Answer:
The answer is following:
Explanation:
The definition of pH is "power of hydrogen ions," as stated above.
An indicator of a solution's acidity is its hydrogen ion percentage. A much more acidic solution is indicated by a greater concentration.
The pH equation is
pH = -log(H+)
In this way, pH serves as a measurement for hydrogen ions.
The hydrogen ion potential increases with increasing pH negativity. Hydrogen is the meaning of the H in pH. However, there is significant disagreement regarding what the p stands for. According to the Carlsberg Foundation, pH stands for "power of hydrogen." The French argue that it is their term for power, puissance, while German scientists assert that it refers for Potenz, which also means power. According to ancient Romans, the word is pondus hydrogen (Latin for "amount of hydrogen"). The British would say that the possible hydrogen is the only complexity involved.

In terms of fatalities, the most dangerous natural disasters are caused by ____.
In terms of fatalities, the most dangerous natural disasters are caused by long term weather patterns that causes droughts.
A drought is a prolonged period of unusually dry weather caused by a lack of rain. A lack of precipitation can cause a number of issues for local communities, such as crop damage and a lack of drinking water.
Drought and certain weather patterns have been linked by geologists. A weather pattern reveals where the temperature of the surface water in the Pacific Ocean rises along the central South American coast. Warmer waters influence storm patterns and are linked to droughts.
When the temperature of the Pacific Ocean's surface water along South America's coast falls. The cooler waters influence storm patterns by causing drier-than-normal conditions. As a result, climate/weather change increases the chances of drought worsening in many parts of the world.
How drought is impacted by climate change?
Warmer temperatures accelerate evaporation, which decreases surface water and dries out the soil and vegetation. Low precipitation periods become drier as a result, as opposed to when it is cooler. Affected areas are becoming drier as a result of climate change's timing changes for water availability.
