Final answer:
Coal formation proceeds through stages that represent increasing carbon content and energy potential: starting with peat, then transforming to lignite, subbituminous coal, bituminous coal, and finally, anthracite.
Explanation:
The successive stages in coal formation from first step to last are:
Peat - This is not actually coal, but the precursor to coal, formed from decaying plant material in wet environments.Lignite - Also known as 'brown coal', is the lowest rank of coal and has the lowest energy content.Subbituminous coal - This is a rank above lignite, with a higher energy content and lower moisture content.Bituminous coal - This has even higher energy content and is the most abundant form in the Eastern United States, though it contains sulfur impurities that contribute to acid rain.Anthracite - The highest rank of coal, with the highest energy content and a glossy appearance. Anthracite is less common and was largely depleted due to its desirability.Which of the following is the most distal part on a human arm?

A new element has been discovered. Newelementium has 40 more protons than radon. It also has the same number of protons and neutrons. What would newelementium’s atomic number and atomic mass be? (Use the periodic table)
Answer:
Atomic number would be 126 and atomic mass 252.
Explanation: The atomic number is the number of protons in the nucleus of an atom. This number is the position they occupy in the periodic table.
On the other hand, the atomic mass is obtained by adding the number of protons and neutrons of a given nucleus.
Consequently, if Newelementium has 40 more protons than radon and acoording to the periodic table radon has 86 protons, the atomic number is calculated as follows:
1. 86 + 40 = 126
Newelementium would have 126 protons, therefore its atomic number would be 126.
Since Newelementium has 126 protons and the same number of neutrons, its atomic mass would be:
2. 126 (protons) +126 (neutrons) = 252
Newelementium atomic mass would be 252.

A person throws darts at a dart board and the darts are spread all around the bullseye, but not grouped together in one general area. What statement best describes this situation? A) The dart thrower is accurate and precise. B) The dart thrower isn't very accurate or precise. C) The dart thrower is accurate but not very precise. D) The dart thrower is precise but not very accurate. Eliminate
Answer:
Answer C)
Explanation:
The person throwing the darts it is not successful in reaching the intended target, but the darts are around the bullseye, therefore the person is accurate. This person is not precise because the darts are not close to each other. This difference between precision and accuracy its used for scientific purposes.

Choose which tissue type likely functions to add support to an organ.
The connective tissue, specifically types such as cartilage and bone, is designed to provide support and maintain the structural integrity of organs. They offer flexible and rigid frameworks respectively and withstand various physical stresses to maintain organ stability.
Explanation:Tissue Type That Functions to Add Support to an Organ
The connective tissue is the type that likely functions to add support to an organ. Within the human body, there are various types of connective tissues that each play a crucial role in supporting and maintaining the structure of organs. A particular form of supportive connective tissue includes both cartilage and bone. Cartilage provides a flexible yet strong framework that can resist compression, making it an essential component in joint areas and the growing portions of bones. Bone, on the other hand, offers a rigid structure due to its mineralized matrix, allowing for the protection of internal organs and enabling posture maintenance.
Dense connective tissue proper, also functions as supportive tissue. It is richer in fibers and is found in tendons and ligaments where strength along one axis is especially important. It is also seen in organ capsules and artery walls where strength in multiple directions is needed.
The supportive role of connective tissues is integral to the functionality of organs, ensuring they can withstand various physical stresses and maintain their shape. Knowledge of how these tissues contribute to organ stability is a critical aspect of understanding human anatomy and physiology.

The _______________ completely covers the surface of the protoplasm.
The plasma membrane, or plasmalemma, is the structure that completely covers the surface of the protoplasm, serving as a protective barrier and regulating the passage of substances into and out of the cell.
The structure that completely covers the surface of the protoplasm is the plasma membrane, or plasmalemma. This membrane serves as a protective barrier that regulates the passage of substances into and out of the cell.
In some protozoans, a structure called the pellicle is present just inside the plasma membrane, providing additional rigidity.
Underneath the plasma membrane, ectoplasm and endoplasm form distinct layers of cytoplasm that contribute to complex cell shapes.
The cell wall is another structure described in plant, fungal, and some protistan cells; it is external to the plasma membrane and offers protection, support, and shape to the cell, but it is not the surface that covers the protoplasm in animal cells such as protozoans.
Instead, in protozoans, it's the plasma membrane that completely covers the protoplasm.
A group of college students working on a project on bio-gas have found some bacteria in the bio-gas plant. These bacteria can utilize methane as their source of energy and do not need oxygen for their survival. What kind of bacteria could they be?
Answer: Anaerobic methanotrophs.
Explanation: These bacteria belong to the group of Archae. Methanotrophs are those organisms that use methane as sole source of energy. They are present near the environments where methane gas is present such as marshes, wetlands, and rice paddy.
Methanotrophs that do not need oxygen for their survival are known as anaerobic methanotrophs. Thus, the given bacteria are anaerobic methanotrophs.

What is the least important in determining the plant life in a biome?
The amount of sunlight is the least important factor in determining plant life in a biome.
Explanation:The abiotic factors such as temperature, moisture, sunlight, and soil quality are important influences on plant growth and the type of plants that can thrive in a biome. Among these factors, the least important in determining plant life in a biome would be the amount of sunlight. While sunlight is essential for photosynthesis, it is not the primary determining factor for the types of plants that can grow in a biome. Other factors such as temperature, moisture, and soil quality have a greater impact on the suitability of a habitat for certain plant species.

Is a threadlike form of genetic material loosely dispersed throughout the nucleus when a cell is not dividing?
Chromatin material is a threadlike form of genetic material loosely dispersed in the nucleus when a cell is not dividing.
What is chromatin material?The term "chromatin" describes the DNA and protein combination that makes up the chromosomes present in the cell of humans and other higher creatures. The enormous quantity of DNA in a genome is packaged by several proteins, most notably histones, into a shape that can fit inside the cell nucleus.
The length of all the DNA in a cell, which ranges from 5 to 6 feet, must fit neatly into the nucleus of a cell. The histone proteins are initially wrapped by DNA molecules to create nucleosomes, which are structures that resemble beads on a string. The fibrous substance known as chromatin is made up of condensed/gathered nucleosomes that have gone farther [inaudible]. For DNA transcription and replication, chromatin fibers can unravel.
When cells divide into daughter cells, copied chromatins are further condensed to resemble chromosomes, which are observable under a microscope and are segregated during cell division.
Therefore the genetic material loosely dispersed in the nucleus when a cell is not dividing is called chromatin material.
