Hey there!
For this problem, I would take a look at which answers you can get rid of based on the situation and some common sense:
<span>
<span>A. comparing the cost of raking the lawn, three hours, with the benefit of raking the lawn, $10: </span>This one seems to make the most sense to me, given the situation. Even though she may have the tools to rake the lawn, you would also have to count the time that it would take to complete the task, since it would still be using up a resource. Cost–benefits analysis looks at a lot of aspects, such as money, time, risks, imperfections, uncertainties, etc.
</span>
B. <span>comparing the cost of raking the lawn, $0, with the benefit of raking the lawn, $10: This doesn't apply given the information in my last point, since cost–benefit analysis looks at more than just money.
C. </span><span>comparing the benefit of raking the lawn, $10, with the benefit of not raking the lawn, $0: This one doesn't have a cost, and earning no money for not doing something doesn't sound like a benefit to me.
D. </span><span>comparing the cost of raking the lawn, three hours, with the cost of not raking the lawn, no hours: This one just doesn't make sense to me. Spending no hours doing something isn't a cost. Again, it's missing half of the equation, which is the benefit this time.
I would say your answer is A.
Hope this helped you out! :-)</span>
C. Organisms that contain functional recombinant DNA
Transgenic organisms are organisms that have
altered genomes and most transgenic organisms are usually generated in the laboratory
for research purposes. In transgene, the segment of DNA containing a gene sequence
is isolated from a particular organism and inserted into another or different organisms.
The introduction of transgene into an organism is to bring a change in the
phenotype of an organism.
Answer:
Cancer is characterized by uncontrolled growth and division of certain body tissues, so forming a tumor. A tumor results from uncontrolled growth of cells but all tumors are not cancerous.Based on their spread tumors are classified as benign and malignant. A benign tumor remains confined to the particular organ and do not spread to other parts as these are enclosed in a sheath of connective tissue.Malignant tumors grow slowly during the latent stage but soon they start growing faster and start effecting the normal functioning of surrounding tissue. This stage becomes the metastatic stage and the cells from the tumors metastasize i.e. they break from the tumor and migrate to other body organs through the blood or lymph.
Early detection of cancer is necessary because in later stages it becomes incurable most of the time, the most frequently used method is biopsy, Endoscopy, DNA probe analysis radio-logical techniques etc.
I believe the answers can be volcanic ash, dust, and pollen
Answer:
The correct answer is a. donates hydrogen ions to solutions
Explanation:
There are many definitions of what acid is, but the most common one is that an acid donates hydrogen (+) when it dissociates in solutions. Adding hydrogen or (+) to a solution will lower the pH value and then it will make the solution more acidic in the pH range.
