Scientists have found that the fungus Penicillium brefeldianum produces a toxin known as Brefeldin A (BFA), which is able to block transport from the rough ER to the Golgi apparatus. These special properties have made BFA interesting to scientists who study molecular biology. -If a cell were exposed to a BFA what would happen to it?
-The sorting of proteins would be stopped.
-The synthesis of proteins would be stopped.
-The proper folding of proteins would be stopped.
-The packaging of proteins into vesicles would be stopped.

answer: c. two haploid cells

explanation:

your answer should be c) enjoy!

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
