Answer:
Option (c).
Explanation:
Transcription may be defined as the process of formation of RNA molecule from the template DNA with the help of enzymes and transcription factors. The transcription occurs in 5' to 3' direction.
Post trancriptional modification occurs in the RNA molecule that plays an important role in transcription as well as translation. The introns are removed from the RNA transcript and exons joined together is known as splicing. The alternative splicing occurs in which different protein isoforms are formed by the single exons.
Thus, the correct answer is option (c).
Answer:
The correct answer is: (A).
Explanation:
- In the question, it is mentioned that the algae can grow under the conditions of "enough sunlight" and "enough nutrients".
- Sunlight reaches the algae, by first falling on the surface made up of ice and snow and then refracting from there into the top layer of the ice where the algae grows.
- However, the capability of both snow and ice to reflect sunlight is far more than that of refracting sunlight.
- Therefore, the amount of light received by the algae is similar in absence or presence of the layer of snow on the top layer of ice.
- However, on deposition of snow on the layer of the ice, the weight of the ice increases and it sinks below into sea water.
- This allows more nutrient rich sea water to percolate into the ice and reach the algae.
- The algae receive more nutrients from the sea water and hence is capable undergoing better metabolism and growth.
- Hence, more algae are produced under such a situation.
The
correct answer is in the form of chylomicrons.

fats are resynthesized into triglycerides inside the epithelial cells, and
there they're coated by proteins. Such structures are called chylomicrons (small
globules composed of protein and lipid). The chylomicron is water-soluble and
that allows it to travel outside of the cell and enter the lymphatic
capillaries-lacteals.</span>
The correct answer is option C, that is, have poor soils with little organic matter.
In the tropical rain forests, only a thin covering of decaying organic matter is present. The majority of the tropical rainforest soils are comparatively poor in nutrients. The torrential rains and millions of years of weathering have washed the majority of nutrients out of the soil.
In the tropical rain forests, the soils are generally poor in nutrients and all the nutrients are captivated in the living species. The soils in various regions of the tropical rain forests are laterite soils.
