If the year dates of the tree growth rings can be identified, the scientific discipline of dendrochronology can indeed be utilised to establish when a tree was cut down or died naturally. Seasonal climate shifts affect a tree's annual growth, which varies throughout the year.

The study known as dendrochronology, sometimes known as tree-ring dating, uses the annual growth rings that trees create to determine dates on a calendar (Nash 2000). This precise and sophisticated dating technique has been employed by archaeologists for nearly a century.

According to this theory, there must have been physical and biological mechanisms in place in the past that connect present environmental processes with the patterns of tree development that exist today. James Hutton first said this in 1785, and it is now often understood to mean "the current is the keys to the past."

Biomass includes plants, animals, animal waste, paper products, and trash. It can be used to generate electricity, heat, biogas, and biodiesel.

Plants are a significant source of biomass. Growing crops such as corn, wheat, and soybeans can be used to create energy in the form of ethanol, biogas, and biodiesel. The plant matter can also be burned to produce heat or electricity.

Animals are also a source of biomass. Animal manure can be used to generate biogas, which can be used to run engines or generate electricity. Animal fats and oils can also be used as biodiesel, or converted into biogas.

Animal waste is another form of biomass. Manure, animal carcasses, and other organic materials can be broken down and used to generate biogas. Animal waste can also be composted to create compost or fertilizer.

Sunlight is not a form of biomass, as it does not contain any organic material. However, it can be used to power solar cells and photovoltaic panels, which can be used to generate electricity.

Paper products, such as newspaper and cardboard, can be recycled and used to create biomass energy. This is done by breaking down paper into small, fine particles and then burning it to create heat or electricity. The paper can also be converted into biogas.

Finally, trash is a form of biomass. Food waste and other organic materials can be broken down and used to generate biogas, which can be used to run engines or generate electricity. Trash can also be burned to create heat or electricity.

Explanation:

Food labels always state the sugar, fat and salt content in percentage or per 100 grams or per serving to help consumers in their selection of products.

The number of ATP yielded through fat metabolism which makes 9 molecules of acetyl CoA is 108 ATP.

The process of metabolic reactions which convert fatty acids to acetyl CoA is called beta-oxidation. Through multiple steps in beta-oxidation, fatty acids are broken down to produce energy (ATP). Before producing the energy, fatty acids which are made up of carbons must be converted into acetyl CoA in advance.

If 9 molecules of acetyl CoA are produced, it indicates that the fatty acid has 18-Carbons. In other words, each acetyl CoA contains two carbon atoms.

Each acetyl CoA that has been produced, will enter into the citric acid cycle or known as Kreb’s cycle. This cycle yields 3 NADH (9 ATP), [tex]FADH_{2}[/tex] (2 ATP), and 1 ATP. The total ATP result is 12 ATP.

when there are 9 molecules of acetyl CoA, the ATP yielded is 9 x 12 ATP = 108 ATP.

Thus, if each fatty acid in a certain fat can make 9 molecules of acetyl CoA, the amount of ATP that can be made is 108 ATP.

The insertion or deletion of nucleotide bases in amounts that are not multiples of three is referred to as a frameshift mutation in a gene.

This is significant because a cell reads the genetic code for proteins in groups of three nucleotides.

These so-called "triplet codons" each stand for one of the 20 different amino acids that go into making a protein.

The entire gene sequence after the mutation will be misread if a mutation alters this regular reading frame. This may lead to the incorrect amino acids being added to the protein or the development of a codon that prevents the protein from getting longer.

Metamorphism occurs when the heat rising from below causes the part of the metamorphic rock to melt, forming magma.

Metamorphic rocks are formed from other rocks which substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks are formed when the rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, the combination of these factors.

Metamorphism occurs when the solid rock undergo changes in the composition and texture without mineral crystals undergoing melting, which is how the igneous rock is generated.

If there is too much heat or pressure applied, the rock will melt and become magma. This will result in the formation of an igneous rock, and not a metamorphic rock.

A single amino acid substitution in a protein can cause a dramatic difference in the final shape of red blood cells through changes in the protein's conformation.

Proteins are composed of a sequence of amino acids and their three-dimensional structure is determined by the interactions between different regions of the protein, such as the hydrogen bonds, electrostatic interactions, and hydrophobic interactions. These interactions help to keep the protein in its specific conformation, which is essential for its function. A single amino acid substitution can alter these interactions and disrupt the protein's conformation. This can lead to changes in the shape and properties of the protein.

In the case of red blood cells, a single amino acid substitution in a protein that is responsible for maintaining the shape of the cell can cause the cell to change shape. For example, a substitution in the protein spectrin, which is a component of the cell membrane, could cause the membrane to be more or less flexible and thus resulting in a change in shape of the red blood cell. This change in shape can affect the mechanical properties of the cell and can have a significant impact on its ability to flow through capillaries and deliver oxygen to tissues.

Relationships among organisms play a vital role in maintaining the balance and stability of ecosystems. These relationships can be categorized into three main types: mutualism, commensalism, and competition.

In mutualism, both species involved in the relationship benefit. For example, many plants have mutualistic relationships with pollinators, such as bees. The plants provide nectar as a food source for the bees, while the bees help to pollinate the plants, allowing them to reproduce.

In commensalism, one species benefits from the relationship while the other is neither helped nor harmed. The relationship between cattle and cattle egrets is an example of commensalism. The egrets feed on insects stirred up by the cattle as they graze, while the cattle are not affected by the presence of the egrets.

In competition, two or more species compete for the same limited resource. This can lead to the evolution of unique adaptations that allow a species to better exploit a particular resource, which in turn can lead to greater biodiversity in an ecosystem.

Predator-prey relationships also play an important role in ecosystems by controlling population sizes and helping to maintain balance within the ecosystem. In addition, decomposers break down dead organic matter and recycle nutrients, making them available for other organisms to use.

In summary, relationships among organisms in an ecosystem are vital for maintaining balance and stability, and ultimately ensuring the survival of the ecosystem.

Most attributes are inherited, more offspring are generated than can survive, and offspring with more attractive traits will survive and have more offspring than those with less favorable traits.

These three principles result in natural selection, which is an unavoidable process. More environment-adapted organisms are more likely to survive and pass on the genes that contributed to their success. Over time, species change and diverge as a result of this process.
