How does the evolution of resistance in bacteria affect humans

Answers

Answer:

Bacteria, not humans or animals, become antibiotic-resistant. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria. Antibiotic resistance leads to higher medical costs, prolonged hospital stays, and increased mortality.

Which of the following is NOT a polymer?
Nucleotide
Polysaccharide
Triglyceride
Polypeptide

Answers

Answer:

Nucleotide ( monomer )      

Explained Definition:    

The classes of biological molecules may be grouped into the types of polymers they form and the monomers that act as subunits: Lipids - polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids

1. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T). The sugar and phosphate create a backbone down either side of the double helix.

2. Polysaccharides, also called glycans, are large polymers composed of hundreds of monosaccharide monomers. Unlike mono- and disaccharides, polysaccharides are not sweet and, in general, they are not soluble in water. Like disaccharides, the monomeric units of polysaccharides are linked together by glyosidic bonds.

3. Fatty acids form more complex lipid polymers called triglycerides, triacyclglycerols or triacyl glycerides when each single-bonded oxygen molecule bonds to a carbon that's part of a glycerol molecule. ... Triglycerides are also commonly found in foods, especially animal products

4.  polymers are known as polypeptides; monomers are amino acids. Nucleic Acids - polymers are DNA and RNA; monomers are nucleotides, which are in turn consist of a nitrogenous base, pentose sugar, and phosphate group

Con đường vận chuyển nước vậy ông chất khoáng qua thành tế bào sang bào ở thực vật có đặc điểm gì

Answers

Answer:

In plants, minerals and water are transported through the xylem cells from the soil to the leaves. The xylem cells of the stem, roots, and leaves are interconnected forming a conducting channel reaching all plant parts. Thus, there is continuous water movement into the xylem.

Bài giải:

Ở thực vật, các chất khoáng và nước được vận chuyển qua các tế bào xylem từ đất đến lá. Các tế bào xylem của thân, rễ và lá liên kết với nhau tạo thành một kênh dẫn đến tất cả các bộ phận của cây. Do đó, có sự chuyển động liên tục của nước vào xylem.

ou are designing a building that must minimize energy transfer in the form of heat loss. Describe a building shape that you think would minimize heat loss through the surface of the building, and explain how that shape relates to the surface area-to-volume ratio.

Answers

Answer: In principle, to minimise heat transfer through the building envelope the building shape should be as compact as possible,tending toward a cube.

Explanation:

A building's design should be compact and rounded to reduce heat loss through the surface. The optimum shape would be a sphere, but that is impractical for a building. It would be more practical to construct a building that is cylindrical or dome-shaped.

What should be the shape of building to minimize the heat?

The optimum shape would be a sphere, but that is impractical for a building. It would be more practical to construct a building that is cylindrical or dome-shaped.

By lowering the building's surface area, this design limits the region where heat may escape from the structure. The surface area to volume ratio should be taken into account while trying to reduce heat loss.

A building that is compact and rounded, such a cylinder or dome, has a lower surface area-to-volume ratio than a building that is rectangular or square and has the same volume. Accordingly, less heat is lost from the building's surface in comparison to the heat that is kept inside the structure.

Additionally, a compact, rounded building will have fewer corners and edges, which are vulnerable to heat loss. Additionally, the structure can be angled to receive as much sun exposure as possible, which can add to the building's heating capacity during the winter.

Therefore, a building's design should be compact and rounded to reduce heat loss through the surface.

A student observes a reaction with an enzyme in a beaker. If nothing is removed from the beaker containing the reaction, what is the only thing the student must add to start the reaction again?


A.acids





B.enzymes

C.products



D.substrates

Answers

Answer:

90% Products, 10% Acids

Explanation:

enzymes are not consumed in a reaction. they remain mixed with reactants. if all products have reacted in the reaction and there's nothing left, the answer is products.

But acids promote chemical reactions at certain incidents. especially if it's an essential compound to the reaction.

Ex-: Sucrose is hydrolysed to Fructose and glucose by heating with an acid. but using sucrase, the same can be done.
