There is a moth in England called the peppered moth. Before Britain's industrial revolution, these moths were usually salt and pepper colored. Because of their coloring, they blended in well with the tree trunks on which they tended to rest. The coloring helped them hide from the birds that ate them. During the British industrial revolution, industry expelled a lot of soot from the burning of coal into the environment. This soot darkened the tree trunks, and it was noted that black-colored moths were becoming predominant. The idea is that with soot in the environment, black-colored moths fared better than light-colored moths. There is some debate as to whether this is actually the case or not, but for the sake of this question, let's assume it is. In your own words, explain the concepts from the four observations discussed in 12.2 using the moth as an example. In other words, how does the moth illustrate the first observation, the second observation, etc.
Answer:
The correct answer is - natural selection in moths.
Explanation:
This is an event of historical Industrial melanism, an event caused by the process of natural selection. Due to this event, the evolution of dark body colors in moth species that present in such habitats become black by industrial soot.
Peppered moths in the UK were pale grey before the revolution of industries, But after the habitat become polluted with soot from coal‐fired industries, melanic snd become numerous and spread to other regions.
After the century the pollution comes down and the pale phenotype becomes the predominant form.

Explanation:
Anthropologists have been studying the role of soybean curd andrelated products in the culture of Hong Kong. The researchers interviewpeople about how frequently they eat soybean products, where they eatthem (at home or in restaurants), and during what time of day they eatthem. The researchers also ask people about how they preparesoybean products, where they obtain soybean products, and any beliefsthey might have about soybean products (such as their nutritionalvalue). The data are used to assess the role of soybean products in theculture. The researchers are also considering how their findings relateto global soybean consumption patterns.
1. What is the primary field of anthropology addressed in this research?a. Linguistic anthropologyb. Archaeologyc. Biological anthropologyd. Cultural anthropology2. Which field of anthropology (other than the one you indicated above) is most related to this research?a. Biological Anthropologyb. Archaeologyc. Linguistic Anthropologyd. Cultural Anthropologye. All fields of Anthropology are related to this topic3. How might this research contribute to a comparative anthropological approach?a. This research could be used to compare quinoa consumption in other parts of the world.b. This research could be used to compare biological adaptations across Bolivia.c. This research could be used to compare quinoa consumption in other primate species.d. This research could be used to compare quinoa DNA to other plants.
Answer:
1.) Cultural Anthropology
2.) Biological Anthropology
3.) The research could be used to compare quinoa consumption in other parts of the world.
Explanation:
Anthropology is a scientific field that studies humans. It studies humans all over the world with respect to their behaviors and cultures in both past and present eras. Anthropology is divided into four major types: Cultural, Biological, Linguistic and archaeological.
1.) Because this research is towards the role of soybean and related products in Hing Kong, we can confidently say that it falls under the cultural aspect of anthropology which focuses on the study of differences in cultures among humans.
2.) Considering the fact that the research deals with a biological product (soybean) that has effects on humans, then biological anthropology is the most closely related field.
3.) The researchers intend to relate their findings from this research to global soybean and other related products consumption pattern. Therefore, this research could be used to compare quinoa consumption in other parts of the world.

what is the base-pair rule for a DNA strand matching an RNA strand?
Explanation:
The base pairing of guanine (G) and cytosine (C) is just the same in DNA and RNA. So in RNA the important base pairs are: adenine (A) pairs with uracil (U); Guanine G() pairs with cytosine (C).
The Chargaff rule only holds true for DNA. Base pairing doesn't take place since RNA is single-stranded. Consider a DNA strand.
What make base pair unique in DNA and RNA?Compare the two DNA strands' base-pair rules to this one. Since uracil is absent from DNA, T and A complement one another. In contrast, T bonds with A and A bonds with U in a DNA/RNA match.
Important: It serves as the foundation for base pairing. This rule can be used to both determine the DNA strand length and if a base is present in the molecule.
Adenine and thymine are always equal, and cytosine and guanine are also always equal, allowing us to calculate the percentages of each base.
It assists in figuring out the makeup and structure of DNA in various species. It is constant within a species.
Therefore, the base-pair rule for a DNA strand matching an RNA strand.

B.
Acid rain breaking down the surface of a rock.
C.
A glacier weathering a mountainside.
D.
Wind depositing sand to build up sand dunes.
Answer:
D
Explanation:
because wind is depositing sand to build
Wind depositing sand to build up sand dunes best illustrates a natural process acting as a constructive force. Therefore, the correct option is D.
What is a constructive force?Constructive forces are the forces that are responsible for the formation of new landforms on the surface of the earth, such as deposition, earthquake, volcanoes etc.
Wind depositing sand to build up sand dunes is the natural process depicting the constructive force because sand dunes are formed by constructive forces that add sediment to an area, in this case, wind depositing sand.
Option A is incorrect because river erosion is a destructive force that wears away soil and rock, rather than building it up. Option B and option C are also destructive forces. Therefore, the correct option is D.

Desiccation resistant spores, protective and complex reproductive organs, and embryos nourished by parental tissues enable land plants to ______.
Answer:
to adapt to dryland conditions
Explanation:
The main groups of land plants are vascular plants and they have developed diverse adaptations to survive on land, especially in climatic zones where drought and high temperatures are common. Some of the most important plant adaptations to land ecosystems include, among others, the development of a cuticle to prevent water loss, stomata capable of regulating water evaporation, desiccation-resistant spores coated in sporopollenium polymer, etc. Moreover, in seed plants, which are considered to be the most evolved vascular plants, the endosperm tissue produced inside the seeds is nourished by the parent sporophyte during the first stages of plant development.
Desiccation resistant spores, protective and complex
reproductive organs, and embryos nourished by parental
tissues enable land plants to adapt to dry conditions.
What is Dessication?
This is the process in which a substance dries up as a result of
loss of moisture.

1. Suppose you lived over 100 years ago and you had a whole bowl of
fresh milk but only one cup of yogurt left. Describe how you might
make more yogurt?
Answer:
Lactic Acid Fermentation
Explanation:
Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars are converted into cellular energy and the metabolite lactate, which is lactic acid in solution. Lactate, which is just the deprotonated form of lactic acid, gives the process its name. The bacteria that make yogurt carry out lactic acid fermentation, as do the red blood cells in your body, which don't have mitochondria and thus can't perform cellular respiration.

Which model represents a DNA molecule?
Answer: The answer is D because the way they line up!!
Explanation:
The model that gives a true representation of a DNA molecule would be the 4th model.
What is the structure of DNA?According to Watson and Crick, the DNA is a double strand molecule with each strand twisting around one another to form a ladder-like, double helix structure.
Also, there is a complementarity of nucleotide bases such that Adenine (A) always pairs with Thymine (T) while Guanine (G) always pairs with Cytosine (C).
Thus, model 4 ticks all the characteristics of a typical DNA molecule.

One theory of early life on Earth states that the first life forms did not use oxygen for respiration and were unable to make their own food. Based on this theory, which types of organisms were most likely present? *
A. aerobic, autotrophic bacteria
B. anaerobic, autotrophic bacteria
C. aerobic, heterotrophic bacteria
D. anaerobic, heterotrophic bacteria
The theory of primitive life on Earth is fascinating, there are countless scientists who try to explain how life began on Earth, but to be able to answer how the first living beings were we need to know that.....
Oparin and Haldane hypothesis
The most widely accepted hypothesis about the origin of life today is the Oparin and Haldane hypothesis. According to this idea, the primitive Earth would be constituted by
AmmoniaHydrogenMethane and Water vapor,which are constantly expelled by volcanic activities. The condensation of this water vapor gave rise to a cycle of rains, as these, upon reaching the still hot surface of the Earth, evaporate again, thus initiating a new cycle.
Through the action of the sun's ultraviolet radiation and constant electrical discharges, the elements present in the atmosphere began to react, giving rise to the first organic compounds, called amino acids. The rains carried these compounds to the primitive oceans, which formed when the Earth's surface cooled, allowing water to accumulate on the surface.
In primitive oceans, these amino acids joined together, forming protein-like compounds (proteinoids), and then, after further reactions, these gave rise to coacervates. These became more stable and complex, controlling their own chemical reactions and being able to self-duplicate, thus giving rise to the first living beings.
Heterotrophic and autotrophic hypotheses
Some authors believe that the first organisms would be heterotrophs. This was due to the fact that the first organisms were simple, lacking the structure to carry out a more complex biochemical process to obtain food, for example, photosynthesis. Thus, these organisms fed on simple organic matter, presenting as the end product of this process carbon dioxide (CO2) and alcohol (C2H5OH), that is, the first living organisms would be fermentors.
With this information, we can say that the first living being on the planet was anaerobic, heterotrophic bacteria.
D. anaerobic, heterotrophic bacteria
There have always been many theories about the origin of life on the planet, but this is the most acceptable among scientists, but it is necessary to know that they are not yet fully proven, so they continue as a theory.
