As part of an experiment, you grow some plants in an environment including carbon dioxide with radioactive carbon isotope 14C as a tracer. After a few days you take the plants out and look for the tracer. You find it primarily in the roots. How did it get there? Why is it in the roots?
Answers
Answer:
Plants make their own food with the help of photosynthesis, in which the organic carbon is formed from the inorganic carbon. Organic carbon is used as a source of energy and helps in various cellular functions.
Organic carbon mostly stored in the form of starch and other carbohydrates and also helps in forming the structure of the plants. The starch is stored mainly in the roots, fruits and stems. The main source of starch is in roots in tubers of the plants. The radioactive carbon that is found in the plant roots in the experiment is the excess carbon that stored in the roots of the plants

Compare and contrast the genome organisation, infection strategies and diseases of a multipartite and monopartite virus.
Answers
Answer:
Multipartite viruses have one of the most puzzling genetic organizations found in living organisms. These viruses have several genome segments, each containing only a part of the genetic information, and each individually encapsidated into a separate virus particle. While countless studies on molecular and cellular mechanisms of the infection cycle of multipartite viruses are available, just as for other virus types, very seldom is their lifestyle questioned at the viral system level. Moreover, the rare available “system” studies are purely theoretical, and their predictions on the putative
benefit/cost balance of this peculiar genetic organization have not received experimental support. In light of ongoing progresses in general virology, we here challenge the current hypotheses explaining the evolutionary success of multipartite viruses and emphasize their shortcomings. We also discuss alternative ideas and research avenues to be explored in the future in order to solve the long-standing mystery of how viral systems composed of interdependent but physically separated information units can actually be functional.
The perusal of the literature presented above illustrates our current ignorance on the reasons explaining why multipartite viruses are so successful. The simple fact that they can be ssRNA, dsRNA, or ssDNA likely indicates that multi-encapsidation has evolved more than once, and yet we are unable to confirm any associated beneficial aspects. The proposed putative benefits are not yet convincing because of a lack of data, and because most also appear valid for segmented virus, thus not explaining multi-encapsidation. We believe further experimental work on the specifics of the biology of multipartite viruses is necessary to evaluate and challenge the existing hypotheses, and, even better, propose new ones perhaps more pertinent or unforeseen. A possibility that should not be ignored is that, because multipartitism most likely evolved independently several times, its evolution may have responded to distinct selection pressures: it is possible that the reasons that led to the evolution of multipartitism differ in different groups of viruses and that potential benefits that exist in one group do not exist in another. As concluding remarks, we outline a few research lines that could clarify or assign specific properties to multipartite viruses that we judge immediately critical.
Structural, physical, and biochemical properties of the virus particles depending on the contained segment(s) should be investigated in more detail. An important outreach of these studies (detailed in section 4) is that distinct properties of particles containing different segments may reflect an adaptive process involved in the temporal regulation of gene expression specific to multipartite viral systems. Although such variable particle properties were shown to be related to the RNA folding structure, they may also be important for multipartite ssDNA viruses in which secondary/tertiary folding structures of various segments appear to have unknown biological functions [97].
Also related to the regulation of gene expression, the discovery of the genome formula in populations of the nanovirus FBNSV [50] contributes to the consideration of a putative important role of gene copy number variations in the biology of viruses. Prominent questions are whether the genome formula is also controlled in other multipartite viruses, whether it actually regulates gene and phenotype expression, and whether it is an adaptive and evolvable trait. While arguments in favor of the adaptive regulation of gene copy number in multipartite viruses are discussed in section 3, a direct experimental demonstration is still lacking.

Answer:
I think the answer is Carbon Dioxide & Water & ATP.
New compounds are formed during cellular respiration are carbon dioxide,water, and ATP. Thus, option B is correct.
What is cellular respiration?
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP ( Adenosine triphosphate) that can be used by the cell. Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is in cellular respiration, glucose and oxygen react to form ATP ( Adenosine triphosphate)
Adenosine triphosphate is an organic compound which gives energy to living organisms to drive many operations in living cells. such as muscle contraction, muscle pumps, nerve impulse propagation, condensate dissolution, and chemical synthesis.
Respiration is a phenomenon in which metabolic process is take place in the living organisms. It is biochemical process which takes place in the cell of organisms. In respiration energy (ATP- Adenosine triphosphate) is developed by splitting of glucose which will further used by cell to perform various function. Single-celled organisms always dominant over the multicellular organisms.
Therefore, New compounds are formed during cellular respiration are carbon dioxide,water, and ATP. Thus, option B is correct.

1.Compare the hibiscus and spider lily pollen grain structure.
2.Why stigma at the top of the pistil is often sticky?
3.Why pollen is important in fertilization?
Answers
Answer:
Explanation:
Hibiscus flowers attract pollinators with their bright colors and a bull's-eye pattern leading to a deep throat. The deep throat and prominent stamen and stigma mean pollinators need to bump the stigma to probe deeper in the flower. Pollen sticks to the pollinator and is transferred to the female parts of either the same flower or sometimes a different flower. Pollinators are rewarded for their pollination efforts by by being allowed to consume the surplus pollen the flowers produce.not sure about spider lily
answer for 2 The top part of the pistil is called the stigma and is sticky so it will trap and hold pollen. In flowering plants, the flower functions in sexual reproduction.
answer for 3 The ultimate function of pollen is to deliver male gametes (sperm) from the stamen of a plant to an ovule for fertilization of an egg, which then develops into a seed

Mary loved having her own garden and would often spend many hours tending to its care. She was meticulous in watering the plants,pulling the dreaded weeds, and harvesting the fruits and vegetables as they ripened. Her garden consisted of corn, tomatoes, greenbeans, okra, zucchini, squash, lima beans, watermelon, and cantaloupe. Often, the garden would produce much more than Mary andher daughter, Sue, could eat. Rather than waste the delicious food, the ladies would spend hours on the weekend canning the excessvegetables and fruit. It was something they had done for many years. On this particular occasion, Sue noticed that the pressure cooker,the instrument used to sterilize the canned food, did not seem to be acting quite right, but the cans were hot when they came out soshe figured everything would be okay.Several months after their weekend of canning, the ladies invited the entire family over for Thanksgiving dinner. The meal consisted ofturkey, ham, chicken, macaroni and cheese, rolls, spinach salad, tomatoes, corn, lima beans, green beans, and okra. All of thevegetables were the ones they had previously canned from their garden. For dessert, they had pecan pie and vanilla ice cream. Thenext day, while most of the family was out shopping, four of the family members were home with blurred vision, dry mouth, and muscleweakness. Mary called the family physician, Dr. Franklin, who told her to take the sick individuals to the emergency room, and he wouldmeet them there. Upon arrival at the ER, Dr. Franklin asked what the family members had eaten for the meals before they developedthe symptoms. The common foods that all of them ate were the chicken, the ham, the tomatoes, the green beans, and the spinachsalad. The doctor determined that the family was suffering from botulism food poisoning. In the United States, foodborne botulismhappens in 15% of cases each year, frequently from foods with a low acidity. He was suspicious of the green beans and tomatoes, eventhough tomatoes are highly acidic. Dr. Franklin also said that using proper methods of microbial control could have prevented theirillness.
Which of the following is an example of microbial control?
a. Sue washes off the vegetables before serving them in a meal.
b. Mary warms food up in a microwave before putting it on the table.
c. Sue uses bleach to clean the kitchen counters.
d. Mary places leftovers in the refrigerator after the meal.
Answers
Answer:
Option a (Sue........meal) would be the correct answer. Below however is the explanation offered.
Explanation:
Prevention: Clostridium botulinum seems to be a type of bacteria that is prevalent in soils and seems to be present in raw water. As either a resistant spore, this could live in some of these conditions. And when no indications of food contamination become visible, the spores of the whole bacterium would be hard but instead active however after heating. Boil home-processed foods for at least 10 min while feeding. To destroy the activated spores, ten minutes of warming will destroy the toxins. During at least a few thirty minutes, 120 ° of warming can indeed be achieved with the aid of gravity. Discard any containers that appear broken and are therefore bulging, dripping, smelling.Boiling will kill the bacterial spores as well as the toxins it creates. In house soil, bacteria may also be present.All other three methods are not connected to the case provided. So, the solution here is just the right one.

D
Explanation:
The two types of biomolecules being described in the scenario would be nucleic acids and proteins.
Nucleotides are the building blocks of nucleic acids. Each nucleic acid in the form of DNA or RNA has its nucleotide sequence.
DNA is responsible for the storage of genetic information. In order for genetic information to be expressed, the information in DNA is transcribed into RNA. The genetic codes in RNA are translated to their respective amino acids and linked together by peptide bonds as proteins. Thus, genetic information are usually expressed in proteins and the RNA serves as an intermediate molecule.
