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.

Sequence the process of skin repair in response to a cut.

The cascade of healing is divided into these four overlapping phases: Hemostasis, Inflammatory, Proliferative, and Maturation. Hemostasis, the first phase of healing, begins at the onset of injury, and the objective is to stop the bleeding.

Suppose the rate of plant growth on isle royale supports an equilibrium moose population of 850 moose in this scenario there are
lesya692 [45]

The population of moose will still be around 850 in 30 years.

<h3>What is carring capacity?</h3>

Carrying capacity is the number of individuals that an environment can support without significant negative impacts to the organism and its environment.

With that being said, the moose population size will be same or still 850 after 30 years. Rate of plant growth on isle Royale supported in equilibrium moose population of 850 moose and if there will more 200 mooses arrived then there will be no sufficient plants available to feed those additional mooses. This is the concept of carrying capacity. Carrying capacity is defined as the species average population size in particular habitat. Species population size is restricted by environmental factor like food, shelter, etc. If number of mooses will be increased in particular habitat and plants are limited ,then there will be strong competition between them, which results in survival of the fittest.

So when population size increases on Isle Royale,may be in beginning, for a while there will be sufficient plants to feed those additional 200 mooses, but after some time plant population will reduce and there will be not enough plants to feed all of the mooses. And if needs are not met, population will decreases which allows plants to grow in normal population to feed 850 mooses. So, after 30 years moose population size would be around 850 mooses.
