Answer: a. Intervention study
Explanation:
In an interventional research study the participants receive an intervention as they are given a new item or commodity to use and the results of use are evaluated on the basis of change made by the commodity on the participant. Such studies are used for the purpose of clinical trails.
The given research design is the example of interventional study. As the margarine is a new commodity the ingredients of which are claimed to lower down the blood cholesterol levels which can tested by comparing the cholesterol levels in people.
DNA stands for deoxyribonucleic acid. RNA stands for ribonucleic acid. Both RNA and DNA contain Adenine, Cytosine, and Guanine. However, DNA's nitrogenous base is Thymine while RNA's nitrogenous base is Uracil.
<h2>Option (B) is Right Answer</h2>
Explanation:
(B) bacteria that make insulin for is right answer
- <em>The human insulin gene and embedded into the bacterium Escherichia coli</em> to deliver manufactured <em>"human" insulin</em>
- The develop insulin modestly, the quality that produces human insulin was added to the qualities in an normal E. coli microscopic organisms.An example of microbes is then<em> "infected"</em> with the plasmid, and some of them take up the plasmid and fuse the new quality into their DNA
- <em>A plasmid is a little, round, twofold stranded DNA atom that is particular from a cell's chromosomal DNA</em>
Answer:
Enzyme-controlled chemical reactions combining carbon dioxide and glucose water. The photosynthetic rate is affected by the temperature much like any other enzyme-controlled reaction.
Explanation:
At low temperatures, the number of molecular collisions between enzymes and substrates limits the photosynthetic rate. Enzymes are denatured at high temperatures.
Enzymes are protein molecules used in biological reactions by living organisms. The proteins are folded in a very specific form, which enables them to effectively bind to the molecules of interest. The enzymes used for photosynthesis perform less efficiently at a low temperature between 32 and 50 degrees Fahrenheit 0, 10, and 10 degrees Celsius, which lowers the photosynthesis rate.This will lead to lower glucose synthesis and slow growth. In the case of plants in a greenhouse, this is prevented by installing a greenhouse heater and thermostat.
<span>E)detritus-insect-frog-snake would best represent the food chain.
Detritus is a residual from plants that are decomposed. This will be eaten by insects such as flies.
After that, the flies will be eaten by the frogs who hunted on ponds before they eventually eaten by the highest level carnivore (such as snakes or Big birds)</span>
