1.Explain the nature of social science in contrast with the nature of natural science ?
2. What are the social sciences and why is it important to study the fuctioning of human society?
Answer:
1-One of the major differences between the two is that humanities involve a more critical and analytical approach whereas social sciences deal with more of a scientific approach. ... As there is a scientific approach to social sciences, it is considered to be a branch of study in between humanities and natural sciences.
2-Social science examines the relationships between individuals and societies, as well as the development and operation of societies, rather than studying the physical world. These academic disciplines rely more heavily on interpretation and qualitative research methodologies. ... Political science.
Sociology.The societal behavior is studied and analyzed to achieve broad goals. Social research also contributes to societal development by increasing creativity and innovation. The new idea leads to the up-gradation of society. Focusing on research enhances the knowledge thereby giving more power to the society.

Rock pocket mice live in the deserts of the American southwest. Ancestral pocket mice all had light-colored coats that blended in
with the region's rocks and sandy soil, keeping the mice hidden from predatory owls. About 1.7 million years ago, a series of
volcanic eruptions spewed out wide trails of black lava into the middle of rock pocket mouse territory. Currently there are two color
morphs of rock pocket mice: light-colored mice that are typically found in habitats with sandy soil, and dark-colored mice that are
typically found in habitats with dark-colored lava rocks.

Some bacteria possess antibiotic resistance, as well as the ability to survive through adverse conditions. Where in this type of bacteria is the DNA located?
a. nucleoid, fimbriae , and plasmids
b. fimbriae, nucleoid, and endospore
c. endospore, fimbriae, and plasmids
d. plasmids, nuclouid, and endospore
Answer:
d. plasmids, nucleiod, and endospore
Explanation:
Bacteria are prokaryotic organisms i.e. they do not possess a well defined nucleus in their cells. However, according to this question, some bacteria are said to possess antibiotic resistance, as well as the ability to survive through adverse conditions. These two characteristics of some bacteria is attributed to the possession of a plasmid and endospore respectively.
A plasmid is a circular extra-chromosomal DNA found in bacterial. It is termed "extra" because it is different from the DNA of the bacteria and carries different genes. The genes contained in the plasmid often gives the bacteria added advantage like antibiotic resistance. On the other hand, endospores are asexual spores produced by bacteria in order to withstand adverse environmental conditions like drought etc.

Explain this diagram?????????
Answer:
the diagram explains the process of DNA digestion and DNA ligation, which is usually used in molecular cloning techniques
Explanation:
Molecular cloning can be defined as the process used to synthesize multiple copies of a particular DNA fragment. Molecular cloning requires the insertion of a foreign DNA fragment into an appropriate vector (e.g., a plasmid) through the action of specific enzymes that serve to cut and ligate DNA fragments. DNA digestion and DNA ligation use specific restriction enzymes and DNA ligases, respectively, in order to insert the foreign DNA fragment. For this purpose, restriction enzymes that generate single-stranded overhangs are preferred to create sticky ends which bind by complementary base pairing. Subsequently, a DNA ligase enzyme joins the DNA fragments together in order to create recombinant DNA molecules. DNA Ligation is often achieved by using a specific T4 DNA ligase, while there are many restriction enzymes that generate sticky-ends (e.g., BamHI, EcoRI, BaI228I, etc).
Your first assignment is to provide information to the firm BigMoney Inc., a chemical producer in Kansas interested in using microbes to clean toxic spills (bioremediation). BigMoney Inc. has had a major spill of inorganic S that contaminated the soil around their plant. Scientists at BigMoney have developed mechanisms for removing H2S from soil, but have not found one for S. They want to know on a strictly theoretical basis (regardless of whether bacteria exist in nature that actually do these specific reactions) if there are any types of bacteria that could use S to give rise to H2S. (7 points total)
S ? H2S (-0.274)

Put the following events in the correct order:
A. The amino acid sequence built from the mRNA varies
B. As the DNA sequence varies the mRNA sequence that is created during transcription
varies,
C. Since the structure of the protein determines its function we see variation in the traits
expressed due to how that protein ultimately functions based on its shape
D. This causes the structure of the protein to be different because different amino acids
are used.
Answer:
B → A → D → C
Explanation:
This question involves gene expression, which is the process of how gene is used to synthesize proteins that determine the phenotype or traits of an organism. Gene expression involves two processes namely: transcription and translation.
- Transcription is the process whereby a DNA template is used to synthesize a mRNA sequence.
- Translation is the process whereby the mRNA transcript is used to synthesize an amino acid sequence, which eventually becomes a protein.
Based on this, the correct order of sequence of events given in this question will be:
- As the DNA sequence varies, the mRNA sequence that is created during transcription varies (transcription).
- The amino acid sequence built from the mRNA varies (translation).
- This causes the structure of the protein to be different because different amino acids are used.
- Since the structure of the protein determines its function we see variation in the traits expressed due to how that protein ultimately functions based on its shape.
Explain two possible reasons why a person who looks well could still be a source of infection microorganism?
Answer:
- many pathogens exhibit a latency (asymptomatic) period of incubation
- usually, pathogens need to replicate many times in order to be transmitted between hosts (i.e., they need to increase the pathogenic load)
Explanation:
The latency stage refers to the period between being exposed to a particular pathogenic microorganism (for example, a virus) and has symptoms associated with the disease caused by such pathogen. Generally, this incubation stage is asymptomatic, thereby a person will look healthy during this period. Moreover, the pathogenic load (usually known as the viral load in viral infections) can be defined as the number of pathogenic microorganisms in an infected person's blood. During the first stages of infection, the pathogenic load usually is low, whereby a person can also look healthy during this period.

list ways in which invertebrates compensate for not having a spine
Invertebrates can be simply identified as animals that do not have a backbone. To compensate for the lack of an internal skeleton, most invertebrates have an external skeleton that protects their soft, inner body.
Invertebrates compensate for their inability to possess a backbone ( spine ) by having ; An external skeleton ( exoskeleton )
What are invertebrates ?Invertebrates are animals without backbone and also lacks an internal skeleton. The exoskeleton present in invertebrates helps in the protection of the outer surface of the organism from external stimuli and also aids in the movement through internal muscles.
Invertebrates compensates for the absence of a backbone through the possession of an exoskeleton which performs similar function just like the endoskeleton.
Hence we can conclude that Invertebrates compensate for their inability to possess a backbone ( spine ) by having ; An external skeleton ( exoskeleton ).

Answer:
Disulfiram is a drug used to support the treatment of chronic alcoholism by producing an acute sensitivity to ethanol by inhibiting the enzyme acetaldehyde dehydrogenase, an enzyme which catalyze the conversion of acetaldehyde into acetic acid. Thus, in the presence of disulfiram, the concentration of acetic acid is reduced

Answer:
B.They hadn't turned the telescope toward the night sky.
They thought Earth was the center of the universe. Option D is the correct answer.
What was the time when Galileo saw Jupiter's moons ?Galileo saw these Jupiter's moon around 1600 and the decade.
Galileo was almost unable to just see then every moon on the each night and the reason for this is that some of just moved away too too far in process of the orbit for the weaker telescope to just view. In that case clearly they just orbited then Jupiter in the same way and as the Moon orbits Earth.
And if the moons can orbit the planet, in that case perhaps it is true where the Earth orbited Sun after all in the end . Galileo hadn't seen moons around the Jupiter as it is almost failing geographic observations. Jupiter's moons although do not appear to orbit Earth.
