Answer:
C) run a statistical analysis on the data collected
Explanation:
A) False
You can only start investing in drug company after analysing all the results of the experiment, then you need to develop the drug correctly so then you can start making experiments with a larger amount of pacients to test the efiiciency of the drug so finally you can sell it.
B) False
You can only conclude this after reviewing the results. Without analysis, nothing can be concluded.
D)False
You only start a new hypothesis after the first one has been rejected by data analysis. If the drug has no effect on patients, a new hypothesis will need to be developed. But you will only know this after analyzing the results of the experiment.
Answer:
O Cell membrane: surrounds a cell and allows substances to pass in and out
Explanation:
Cell membrane is also called plasma membrane. Cell membrane is the boundary of the cell which helps in the protection of the cell from external environment. Cell membrane is a semipermeable membrane which has small pores that allows substances such as water, glucose, Sodium ion, oxygen and carbondioxide etc to pass through it.
Answer:
The correct answers are: b) "An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues", c) "Soluble proteins that misfold and form amyloid fibrils become insoluble", and d) "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".
Explanation:
Amyloid fibrils are protein aggregates that can cause pathological conditions, for instance, they are found in brain tissue in people with Alzheimer disease. This disease, and other relates diseases, have a slow onset because most newly synthesized proteins fold correctly and the protein aggregates are made up misfolded proteins. This newly synthesized proteins are soluble, but once the proteins are misfolded, they form amyloid fibrils that are insoluble. The amyloid fibrils are stabilized by hydrophobic interactions between aromatic residues, which are formed within the complex of insoluble misfolded proteins.
There are three slopes in a survivorship curve, which indicates the average life expectancy of a population.
Type I<span> or convex curves in which few offsprings are produced, but they are cared well and get matured and survive.
</span>Type II or diagonal curves where al almost constant rate of birth or mortality is observed.
Type III or convex curves where high mortality is observed in early life, but the aged population has a high survival rate.
