1. Which layer is the oldest? Which layer is the youngest? How do you know?
2. What are some characteristics of the organisms in layers 1-6?
3. What are some characteristics of the organisms in layers 7-12?
4. Develop a theory as to how the organisms in this area changed over time.
Answer:
the youngest layer is 7(middle point) because decomposition must occur in the middle of decomposed materials.the oldest is 12(upper one) because decomposed material are found at the top most of organisms.they are highly decomposed material.they don't decompose easilyThe youngest layer is 7(middle point) because decomposition must occur in the middle of decomposed materials. The oldest is 12(upper one) because decomposed material are found at the top most of organisms. They are highly decomposed material. They don't decompose easily.
What is Decomposition?Decomposition of organic matter is a complex process that involves the breakdown of complex molecules into simpler ones by the action of microorganisms. In the case of the layers mentioned, the higher layers are the oldest because the decomposed material is found at the top of the layer, and it takes a long time for the organic matter to decompose into soil.
The highly decomposed material in these layers is called humus. Humus is a dark brown or black organic substance that is a result of the decomposition of plant and animal matter. It is an essential component of healthy soil as it provides nutrients to plants and helps retain moisture in the soil.
Humus does not decompose easily because it is a stable form of organic matter. It is made up of complex molecules that are resistant to further decomposition. This makes it an important component of soil fertility as it can remain in the soil for hundreds of years, providing a steady source of nutrients for plants.
Overall, the highly decomposed material found in these layers is an important indicator of the age and health of the soil. Understanding the decomposition process and the factors that affect it can help us better manage our soil resources for agriculture, forestry, and other uses.

The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. View Available Hint(s) The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. a transport protein is involved in the movement of the molecules the lipid bilayer is permeable to the solute the concentration of the solute is lower inside the cell than outside it the concentration of the solute is higher inside the cell than outside it
Answer:
the concentration of the solute is lower inside the cell than outside it
Explanation:
This question depicts the process of ACTIVE TRANSPORT, which is the movement of a substance against concentration gradient, hence, requires energy input (ATP) to occur. In this case, transporting a solute from inside an animal cell to the extracellular fluid across the cell membrane always requires energy.
This is because the concentration of solute inside the cell is much lower than that of the extracellular fluid, hence, to move the solutes against this concentration gradient (low to high), energy in form of ATP is required.

Draw the attention of Protestant churches to the plight of the urban poor.
Explanation:
The main aim and goal of the Social Gospel movement was to bring attention of Protestant churches to the difficult and dangerous solution of the urban poor. The main purpose of this movement is to combat injustice, suffering and poverty in the society. This movement started to solve the social problems such as social injustice, poverty, crime, economic inequality, alcoholism, Racial tensions slums, clean environment and child labor etc. This movement begun in the 20th century and has a great effects on he progressive-minded reformers.

Lea el párrafo que aparece abajo y complete con las siguientes palabras que faltan: hereditaria; cromatina; equitativa; cromátidas; cromosomas; ADN; genes; duplica; brazos y centrómero
Answer:
Hereditario se refiere al proceso por el cual las características se transmiten genéticamente de padres a hijos.
Explicación:
Hereditario se refiere al proceso por el cual las características se transmiten genéticamente de padres a hijos. La cromatina consta de ADN y proteína que se replica antes de la división celular para formar duplicados de ADN que se distribuyen equitativamente entre las células hijas. Las cromátidas se refieren a las dos mitades idénticas de un cromosoma duplicado replicado y el centrómero es la secuencia de ADN de un cromosoma que une dos cromátidas hermanas entre sí y cada cromátida tiene cuatro brazos.

Chromosomes, genes, DNA are different names for different parts of ______________ thing. (I don't understand this???)
Answer:
of the same thing
Explanation:
Deoxyribonucleic acid (DNA) is the molecule that contains the hereditary genetic material in humans and almost all other organisms. Moreover, chromosomes are thread-like structures composed of DNA that contain part or all of the genetic material of a particular organism. Finally, genes are chromosome segments that contain the information needed to synthesize an RNA molecule by the process of transcription, typically a messenger RNA (mRNA) molecule which is subsequently used to encode a protein sequence through the process of translation.

he bodies of wild-type fruit flies are colored by dark pigments, but an X-linked recessive mutation can confer a yellow, unpigmented phenotype. However, feeding silver salts to larvae results in adult flies that phenocopy the yellow phenotype. You are conducting epistasis experiments in fruit flies to understand the genetics of pigmentation. A rival research lab sends you a vial of yellow-bodied flies for your experiments. How can you tell whether these flies are mutants instead of phenocopies
Answer:
We could feed them with another type of food free of silver salts.
Explanation:
When talking about a phenocopy, we are referring to individuals who genotypically should be expressing a determined phenotype, but due to environmental influence, they express another phenotype. This is a non-inheritable phenotype, so it is not considered a mutation.
If we grow thy flies feeding them another type of food that does not include silver salts, and let them mate and reproduce, they will express the real phenotype, because they will not be influenced by the food. In the following generation, there will be dark individuals carrying the dominant allele, and yellow individuals, with the recessive genotype.

If sea lamprey increase in population and decrease the native fish population, the sea lamprey population will eventually collapse (decrease rapidly). This would be an example of _______ feedback. 1. Positive 2. Negative 3. Neutral 4. None of the above
Answer:
Negative feedback
Explanation:
Feedback mechanism is activated due to the change in the system that result into an output.
A negative feedback mechanism is a pathway that is caused by deviation in the output that result in a change in output direction which is usually opposite to the initial deviation.
The process of feeding of sea lamprey on the fish started as a normal pathway the deviation started when they could not feed on the fish again as a result of reduced population and they start dying of hunger. It is a negative feedback

A researcher recently discovered a new species of bacteria in the body of a tubeworm living near a hydrothermal vent. He compared the DNA of this new bacterial species to the DNA of four other species of bacteria. The DNA sequences came from the same part of the bacterial chromosome of all four species. According to these data, the unknown bacterial species is most closely related to
Answer:
That are more similar to each other.
Explanation:
The unknown bacterial species is most closely related to that bacteria which experience high temperature because both bacteria can live and survive in hot climatic conditions. The new species of bacteria and other four bacteria have some similar features due to similar chromosome but also have some differences due to difference in environmental conditions where they survived so those bacteria that have more similarities are more closely related to each other.
