The answer is D) they need large amounts of energy
The following statements accurately reflect the beliefs on Earth's early history:
B. Scientists believe the early atmosphere lacked the oxygen necessary to support modern human life.
The following statements are incorrect:
A. Scientists believe that DNA may have existed before RNA - Scientists actually believe the opposite - RNA may have existed before DNA.
C. Scientists believe that microspheres nearly prevented the development of early life.
D. Scientists believe that oxygen was plentiful in the early atmosphere - again, scientists believed the opposite
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.
Reduction is to bring down the size or value of intensity of a certain thing. Decrease is to decrease or “bring down” of a quantity or to become smaller.
Answer:
Reproductive cells are called: Gametes.
Female Reproductive cells: Egg.
Male reproductive cells: Sperm.
Explanation:
In sexual reproduction each sex has 2 reproductive cells, the egg and the sperm. Sperm fertilizes the egg and the egg will now grow into an embryo. As a whole those two cells are called gametes but depending on gender they have different names.
