Answer:
Explanation:
A) to determine amino acid sequence of the protein produced by that gene. We will use cDNA library, we will hybridize given part of DNA sequence ( as this part only contains exon part). Than we will isolate the hybridize part and translate this sequence using generic coding table.
B) for determine presence or absence of introns in gene used isolated cDNA in first question. Now we will add this cDNA to DNA library. Here cDNA due to complementary mature binds with DNA. If cDNA binds completely with gene with out looping part of gene it shows that gene is having only exons .
And if along with hybridization part some looped part present in between-- it shows both exons and intron are present.
C) for determining alternative splicing we will use cDNA library.
d) to determine length of mature mRNA which includes both the UTR and poly A sequence we will go for cDNA cloning and look for particular cDNA complementary to DNA segments. And later we isolate that cDNA and examine its whole length
E) to determine which cells in the tribble body express this particular mRNA . We use fluorescent tagged small DNA part provided. Then we will add this DNA probe to supplied tribes. The cells which are expressing , will have cDNA will bind to probe and florescent can be detected. Cells which are not expressing that gene, here probe will not bind and no fluorescence.
F) to determine that whose blood strain is this. We will do VBTR profiling . Which VNTR profiling similar to belief stain help to determine which blood stain is this.
Answer:
They have shown in numerous studies that enzyme output gradually decreases with age and may be reduced by more than 60% by the time we reach age 55. At some point in time, we must supplement our enzyme reserves in order to fight the degenerative conditions associated with aging.
Explanation:
b. plants would not be able to grow due to lack of nitrogen.
c. bioremediation would have limited use as a tool to clean up pollutants. .
d. there would be a shortage of decomposer organisms.
e. All of the choices are correct.
Answer:
e. All of the choices are correct.
Explanation:
Bacteria are present almost everywhere on Earth. Many bacteria like cyanobacteria play an important role in fixing the atmospheric carbon in the form of an organic molecule. These organic molecules then used to gain energy.
Many nitrogen-fixing bacteria like Rhizobium, Azotobacter, etc plays an important role in providing nitrogen to plants which is important for their growth. Many bacteria decompose organic matter into simpler form and recycle the nutrients present in them.
So bacteria like Pseudomonas putida decompose waste and clean the environment, therefore, they also help in bioremediation. So the correct answer is e. All of the choices are correct.
Answer: e. All of the choices are correct.
Explanation: Bacteria is an important part of the ecosystem. There are some bacterial species which we called (biological nitrogen fixation (BNF). These bacteria fixes atmospheric nitrogen for higher plants. There are some other bacterial species which feed on dead bodies of living material and helps in cleaning the environment. Due to this decomposition process high amount of carbon is liberated in the atmosphere and used by the plants during photosynthesis.
The reaction of calciumsulfate is double displacement reaction, the reaction of copper and oxygen is synthesis reaction. The reaction of copper oxide and oxygen is single displacement reaction.
When atoms establish or break chemicalbonds, chemical processes take place. Reactants are the substances that begin a chemical reaction, while products are the compounds that are created as a result of the reaction.
Combination, decomposition, single-replacement, double-replacement, and combustion are the five fundamental types of chemicalreactions. You can classify a reaction into one of these groups by looking at the reactants and products.
Calcium sulphate undergoes a doubledisplacement reaction, whereas copper and oxygen undergo a synthesis reaction. Copper oxide and carbon is single displacement reaction.
Thus, first is double displacement reaction, second is synthesis reaction, as well as third reaction is single displacement reaction.

The correct answer is True
Explanation:
In geography, the term "landform" refers to a natural shape or form that can be found on the surface of Earth such as mountains, hills or canyons. All of these are formed through different processes such as movement in tectonic plates. Additionally, these are considered as a physical feature of Earth as landforms define the shape and features of the Earth's surface and also influenced other physical phenomena such as weather or wind patterns. According to this, it is true landforms is a physical feature on Earth's surface.
Answer:
True*
Explanation:
2) What is the hypothesis?
3) Identify the independent variable versus the dependent variable.
4) What variables were held constant in this study?
5) What was the control group?
6) What data was collected during the study?
7) What this data qualitative or quantitative?
8) What was the study's conclusion?
Answer:
1. Research question is a question which is the aim of any experiment or research, in this case, the question addressed by the study is - Testing the effects of a newly developed drug to lessen the effects of the common cold.
2. Hypothesis is an explanation for the reason for any problem it does not need the evidence and completely based on logic.
The newly developed drug is able to lessen the symptoms of a common cold.
3. Independent variable is a variable manipulated or changed during the experiment:
Administration of drug or placebo (sugar pill)
4. Dependent variable is the response to the effect of the independent variable:
Number of tissues for each volunteer
5. Control group is available that remain constant throughout the study or used to compare the results:
Administration of sugar pill to 25 volunteers
6. Data is the result that the study generated -
At the end of the 7 days or one week period, symptoms of common cold disappear in both sets of volunteers who had taken either the drug or the placebo.
7. Data in this study is found is Qualitativedata as the drug is not administrated in doses.
8. Conclusion of the study is that the Placebo effect present as sugar pills relieve the common cold so This drug needs even more analysis.
