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.
What is a scavenger?
A) an organism that lives in or on another organism
B) an organism that feeds on dead matter
C) an organism that produces food from the energy in sunlight
D) organisms that eat plants and grasses
The correct answer is B) an organism that feeds on dead matter.
A scavenger is an organism that obtains its food by consuming dead or decaying organic matter.
These organisms play a crucial role in ecosystems by recycling nutrients and breaking down organic material that would otherwise accumulate.
Scavengers are often attracted to carcasses or decaying organic material, where they feed on the remains of dead plants or animals.
Scavengers can include a variety of organisms from different taxonomic groups, such as vultures, hyenas, flies, beetles, and certain species of bacteria and fungi. They have adaptations that allow them to consume and digest dead matter efficiently.
By consuming dead organic material, scavengers help in the decomposition process, returning nutrients to the ecosystem and maintaining ecological balance. They prevent the accumulation of dead matter, which can lead to the spread of diseases and the release of harmful substances.
In contrast to the other options, which describe different ecological roles or processes, option B accurately characterizes the feeding behavior and ecological role of scavengers in consuming dead matter as a source of nutrition.
Therefore, the correct answer is B.

A tan might indicate sun damage to the skin.
Tanning produces healthier skin.
A tan strengthens the elastic in the skin.
Tanning makes skin look younger.
Answer:
A tan might indicate sun damage to the skin.
Explanation:
Tanning is the process by which the skin is exposed to the ultraviolet rays that comes from the sun with the purpose of producing a dark-brown coloration called a TAN.
A tan achieved by exposure to the sun can actually indicate that a person's skin is undergoing damage from the UV rays of the sun, hence, the skin responds by producing a protein called melanin, which protects the skin and later forms the dark coloration- tan. From this explanation, tan is got in response to a damaging signal received by the cell, hence, a tan might indicate sun damage to the skin.

Explanation:
Adaptations are the alteration that allows the survival of the fittest. The adapted structure of the cacti allows it to take the minerals from the soil and prevents water loss. Thus, options A and B are correct.
What are adaptations of cactus?Adaptation is seen as the modified physical and chemical characteristics that allow the organism to survive in stressful conditions. A cactus has adapted spines, roots, waxy skin, and deep-layered stomata.
These adaptation has allowed the cactus to survive the harsh conditions of dessert. The wide fibrous roots allow it to draw nutrients and minerals from the soil.
The thick, expandable stem with deep-layered stomata prevents the loss of water from the surface in high-temperature conditions and keeps the plant hydrated.
Therefore, options A and B. the adapted attributes of cacti prevent water loss.

What type of RNA acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide
chain?
Answer:
messenger RNA (mRNA)
Explanation:
mRNA or messenger RNA is one of the three types of RNA molecules (the other being tRNA and rRNA) that is specifically responsible for carrying genetic information previously encoded and stored in the DNA into the ribosomes for translation to occur.
The process of translation results to the synthesis of amino acid sequences, which make up a polypeptide. Hence, it can be said that mRNA is that type of RNA that acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide chain.

Discuss how a soil, a natural body, differs from soil, a
material that is used in building a roadbed.
Answer:
Soil is a material made up of gases, organic substances, water, and microorganisms. This material may be used in building a roadbed and is often referred to as dirt. In comparison, a soil is a natural body that is three-dimensional much like a lake or mountain.
Explanation:
Hope this helps
Gases, organic materials, water, and microbes are all components of soil. This substance, which is frequently referred to as dirt, can be utilized to construct a roadbed. In contrast, the soil is a three-dimensional natural structure similar to a lake or a mountain.
What is soil?Soil is the loosely packed organic or mineral material that makes up the Earth's immediate surface and acts as a habitat for land plants. The unconsolidated organic or mineral matter that has been exposed to relief-conditioned macro- and microbes operating on parent material throughout time, as well as genetic and environmental factors such as climate (including water and temperature effects). A product-soil is distinct from the source material in many ways, including in terms of its physical, chemical, biological, and morphological qualities.This is how natural soil is different from the material used in constructing roadbeds.

What is the function of the class of macromolecules represented in the following diagram
Answer:
lods ayarn na:)
Explanation:
The four classes of biological macromolecules are (1) Proteins, (2) Lipids, (3) Carbohydrates, (4) Nucleic Acids.
Proteins are made up of amino acids linked by peptide bonds. They have multiple functions, depending on the number of amino acids and its specific sequence. They serve as major workers composing motor and structural elements in the cell. They can also function as catalytic proteins (enzymes), as well as helpers for storage, signal, transport, reception, defensive, and contractile tasks.
Lipids are made up of fatty acids (a carboxylic acid with a hydrocarbon chain + terminal carboxyl group) and glycerols (organic compound made up of multiple hydroxyl groups). They are a hydrophobic compound that are used for energy storage, thermal insulation, protection, and chemical messengers. Lipids also regulate membrane permeability and aid in fat soluble vitamin production.
Carbohydrates are made up of monosaccharides which build up a polysaccharide (carbohydrates). Monosaccharides are basic sugars which cannot be broken down anymore by water (glucose, fructose, galactose). Carbohydrates' major functions include energy provision, blood glucose regulation, biological processes recognition, and breakdown of fatty acids for ketosis prevention.
Nucleic acids are made up of nucleotides which are organic molecules that forms the Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA). Their structure consists of a nitrogenous base, pentose, and an attached phosphate group. The function of nucleic acids are the creation and storage of genetic information.
