In 2012, excitement rippled through the scientific community with the discovery of an enzyme that appeared to be, just maybe, a

powerful new tool for combating Alzheimer’s. At the Mayo Clinic in Florida researchers identified a gene, BACE2, which appeared to destroy beta-amyloid — a protein, then understood to be toxic, which is found in clusters in the brains of people living with Alzheimer’s. Alzheimer's is often diagnosed by measuring the amount of buildup of this protein. A large amount of it is an indicator of the disease. People with this buildup often do not have enough of the BACE2 enzyme created naturally in their body. If a way to synthesize this enzyme artificially or to prompt the body to create more were discovered, it could be hailed as a cure for Alzheimer's. How does the BACE2 enzyme work?

Answer:

BACE2 cuts both beta-amyloid and beta-amyloid precursor protein.

Explanation:

What makes BACE2 so effective in fighting Alzheimer's is its efficiency in cutting both beta-amyloid and the protein that develops it. There are other enzymes, which have the ability to break down beta-amyloid, but BACE2 is the only one that breaks it down into such small pieces that it completely destroys it. Furthermore, BACE2 is able to break down the beta-amyloid precursor protein, which prevents the formation of beta-amyloid from taking place.

A disorder called osteogenesis imperfecta damages the auditory ossicles and results in hearing loss. why
tamaranim1 [39]
One of the components of the auditory system is the malleus incus and stapes that make up the auditory ossicles. Osteogenesis Imperfacta is a genetic disorder that affects the proper formation of connective tissue in the body. 
Bones, on the one hand, are constituted by connective tissue. The disorder will consequently affect the formation and integrity of the auditory ossicles, therefore, leading to hearing loss.

Compare the processes by which a car and a human use "fuel" to perform work. What are the similarities?
Alenkinab [10]

A car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.

<h3>What is energy?</h3>

Energy is the capacity of doing work. In physics, there exist different types of energy; among which are follows:

  • Kinetic energy: Kinetic energy can simply be defined as that energy a body posses due to its motion
  • Potential energy: , On the other hand, potential energy is the energy a body has due to its relative position.

Other forms of energy include:

  • Solar energy
  • Nuclear energy
  • Mechanical energy

So therefore, a car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.

Therefore, kinetic energy is the energy which allows a car to be fueled before it can set in motion .

Which organism has the least differences in the number of amino acids in cytochrome c compared to
Evgesh-ka [11]

Answer:

Using the number of amino acid differences, it would appear that the two birds are more closely related (had a common ancestor very recently), while the two fungi would have to trace their common ancestry much farther back in time (much more distantly related).

How do nerves pass along messages to and from the brain?
Sliva [168]
The dendrites are covered with synapses formed by the ends of axons from other neurons. ... When neurons receive or send messages, they transmit electrical impulses along their axons, which can range in length from a tiny fraction of an inch (or centimeter) to three feet (about one meter) or more.

State how the amino acid sequence you obtained from the gene fragment for botana curus compares with the sequences for the other
coldgirl [10]

The amino acid sequence in protein from the gene fragment for botana curus is the same with species Z that is valine, histidine, leucine, threonine, proline, glutamine and glutamine. Meanwhile, species X and species Y has different amino acid sequence compared to botana curus. Therefore, species Z is most closely related to botana curus because both species has the same amino acid sequence and has similar sized DNA fragments.
