Answer: propahse. the longest phase of mitosis is prophase because in this phase many structure disappear like nucleus membrane and nucleolus at late prophase nd in early phrophase stage centriole become start dividing and shall go to the pole and mid phrophase stage centriole takes position at 90° between each other and lastly at the.
Explanation:
<span>B.) Species A and B are more closely related to each other than species Y and Z are to each other.
</span><span>Biodiversity depends on a species' ability to reproduce itself. If a species cannot reproduce then it will die out. This depends on the climatic conditions of the region. If there is a natural disaster for example, it will affect a species' ability to reproduce. This reduces the number of diverse species on earth. Biodiversity is the recognised variety of different types of life found on the earth.</span>
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.
When it comes to freshwater wetlands, hydrology plays a large role in
nutrient stoichiometry and sensitivity to nutrient inputs. Although
wetland biogeochemists intuitively understand these important
relationships between landscape position, hydrology, and sensitivity to
nutrient inputs, these relationships have never been quantified using
geospatial data. The objective of this project will be to evaluate and
quantify the linkages between watershed catchment characteristics and
freshwater wetland nutrient sensitivity ur welcome
