Biology
1 answer:
fomenos3 years ago

Answer:

b. False

Explanation:

  • As GPP stands for the gross primary productivity, it's the total amount of energy produced in the process and the NPP is the net primary productivity. NPP is the difference between the GPP and the energy used by the producer for the process of respiration.
  • GPP is a continuous and ongoing process that consumes the energy as compared to the NPP that store energy and not being used. Thus, GPP can affect NPP but NPP does not affect GPP.
  • For example, GPP is completely being dependent on the chlorophyll content of the plant, but NPP is independent of that content of chlorophyll.

Pancreatic cells, which secrete a large amount of digestive enzymes, are labeled with radioactive leucine and then chased for se
stiv31 [10]

Answer:

On the exterior of the cell.

Explanation:

The black spots as mentioned in the given case would appear on the exterior of the cell after three hours, which suggests that the proteins or the enzymes had been discharged from the pancreatic cell. The mentioned method of labeling and then chasing the component is known as a pulse-chase experiment.  

In this experiment, the labeled compounds are used to follow the dynamics of cellular pathways and procedures. The molecules in a cell get produced and degraded spontaneously at various rates. These changes in the localization of the molecule and its expression levels with time can be determined by exposing or pulsing cells to a labeled compound.  

After this the cells are exposed sequentially to the same compound unlabeled, the process is termed as the chase. The compounds are generally labeled with fluorescent dyes or radioisotopes.

Maurinko [17]

The correct answer is: A. A watery mixture of partially digested food released by the stomach into the intestines

Chyme or chymus is formed in the stomach, during the process of digestion (it takes 40 minutes to 3 hours to be produced) , and it is transported to the small intestine-duodenum.

In the beginning of the digestion (in the mouth), mixture of food and saliva called bolus, is formed. Mechanical and chemical breakdown of a bolus creates chime which is ready for the extraction of nutrients from it.
