Answer:
Maltose
Explanation:
Maltose consists of two molecules of glucose that are linked by an α-(1,4′) glycosidic bond. Maltose results from the enzymatic hydrolysis of amylose, a homopolysaccharide (Section 26.9), by the enzyme amylase. Maltose is converted to two molecules of glucose by the enzyme maltase, which hydrolyzes the glycosidic bond. Commercial maltose is produced from starch that has been treated with barley malt.
The monosaccharide unit on the left is the hemiacetal of the α-d-glucopyranosyl unit. It is linked by an α-(1,4′) glycosidic bond to β-d-glucopyranose, the aglycone. The oxygen atom of the glycosidic bond is approximately in the center of the structure, between the two rings. It is projected down, axial, and therefore α. It is linked to C-4 of the aglycone, and so the link is axial–equatorial.
Maltose has a more formal, IUPAC of name: 4-O-(α-d-glucopyranosyl)-β-d-glucopyranose. This rather forbidding name is not quite as bad as it looks. The term in parentheses refers to the glucose unit on the left, which contributes the acetal portion of the glycosidic bond. The term -pyrano- tells us that this part of the structure is a six-membered ring, and the suffix -osyl indicates that the ring is linked to a partner by a glycosidic bond. The prefix 4-O- refers to the position of the oxygen atom on the aglycone, the right-hand ring. The term β-d-glucopyranose describes the aglycone.
Because the aglycone is a hemiacetal, maltose undergoes mutarotation. For the same reason maltose is a reducing sugar. The free aldehyde formed by ring opening can react with Benedict’s solution. The acetal part of the structure is called the “nonreducing end” of the disaccharide. If we do not want to specify the configuration of the aglycone, we use the name 4-O-(α-d-glucopyranosyl)-d-glucopyranose.
Answer:B stabilize the ecosystem
Explanation: Negetive feedback processes are initiated in the ecosystem to stabilize the ecosystem. These negative feedbacks counteract on a particular process im other to create an equilibrium in the entire ecosystem. A good example of negative feedback process is population control. In other to keep regulate and stabilize the ecosystem, predators and preys act to keep population of an environment in equilibrium so that the resources present, which are limited, can sustain the population.
The assessments that the nurse could make to detect this is assess for pedal edema.
<h3>What is pedal edema?</h3>
Pedal edema is a classic symptom of congestive heart failure, but it may also be caused by other regional or systemic conditions.
It can also be caused by chronic kidney disease, liver disease, thyroid disorders, venous insufficiency, and venous thrombosis.
Swelling in the ankles, feet, and legs is frequently caused by oedema, or a buildup of fluid in these areas.
Oedema is usually caused by standing or sitting in the same position for an extended period of time.
Thus, in the given scenario the nurse should access for pedal edema.

Answer:
The Linnaean system of classification is also known as the classical system of biological classification proposed by the Carolus Linnaeus. He categorised the organisms into two groups- the plants and animals on the basis of morphological characters.
But this system has evolved with time from two kingdoms to six kingdom system which is divided into Archaebacteria, Eubacteria, Protista, Fungi Animalia and Plantae with time due to the advancements in technology and understanding of nature into depth.
This shows that knowledge can be modified with time depending on the understanding of nature.
Answer:
The process of asexual reproduction works by mitosis in which a parent cell divides into two or more new identical daughter cells. The number of chromosomes is never changed in such kind of division. A cell must make a copy of its genetic material before the process to ensure that each daughter cell carries the same genome as the parent cell. Vegetative propagation, budding, binary fission etc are examples of some of the methods of asexual reproduction.
