Soloha48 [4]

Answer:

a. Amyloid fibrils have a high amount of β-sheet structure.

c. Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease.

e. Proteins that form amyloid fibrils are normally soluble.

Explanation:

Amyloids can be defined as fibrillar protein aggregates composed of a β-sheet secondary structure. In general, the amyloid fibrils are composed by soluble proteins that are assembled to form insoluble resistant to degradation fibers. In humans, defective amyloid proteins produced by misfolding are known to produce diseases (amyloidosis) capable of altering the function of tissues and organs. Systemic forms of amyloidosis are common in neurodegenerative disorders.

Answer:

The correct answer is - 1990.

Explanation:

From the graph and year - population size table it is clearly understood that the population of grizzly bear is reduced by 39 number from year 1988 to 1989.

But after 1989 from 1990 onwards population of grizzly bear is consistently rising.

Now, let us analyse the data given in question number 2 .

No. of grizzly bear deaths in Alberta from 1976 to 1988 = 581

No. of grizzly bear deaths in Alberta from 1988 to 2000 = 281

From the above data we can clearly say now that the grizzly bear population deaths starts increasing from 1990.

So, the prediction made in question no. 1 that " the government of Alberta introduced the hunting lottery award in 1990 because in 1989 it decreases and then it starts to go up again in 1990",
