Answer:
B. Polysaccharide
Explanation:
A polysaccharide is a carbohydrate molecule made up of several units of monomers called monosaccharides linked together by glycosidic bonds. The monosaccharide is the simplest unit of a carbohydrate with the general formula, (CH2O)n.
However, the monosaccharides, which include glucose, fructose, galactose etc can link up by a bond to form a much larger carbohydrate molecule called POLYSACCHARIDE. As depicted in the image attached to this question, each ring is a monosaccharide, which becomes linked to one another to form a polymer called polysaccharide. Examples of polysaccharides are starch, glycogen, cellulose
The answer is A because that’s the only thing plants “breath”
Answer:
The answers to both parts (1 and 2) are given below.
Explanation:
1. The calorimeter is similar to the bomb calorimeter in a way that both measure the changes in heat that occur as result of the chemical reaction taking place inside them. They are different in the sense that a bomb calorimeter provides an isolated system with constant volume and pressure, whereas a regular calorimeter allows pressure to equalize with the environment.
2. Carbohydrates are the molecules that break down and provides energy for cellular functions. Whereas, proteins are not meant for the production of energy but for the production of amino acids to function as structural units for protein synthesis. Simply, the breakdown of protein is for the synthesis of more proteins by providing several units of amino acids rather than the production of energy.
Answer:
d) alternating sugars and phosphates.
Explanation:
DNA is a molecule which acts as the genetic material of the organisms on Earth. The DNA is made of the monomer units called nucleotides which are composed of a sugar called deoxyribose, a phosphate group and two types of nitrogenous bases (purines and pyrimidines).
The DNA structure is known as the double-helical model which gives a ladder-like appearance in a twisted manner. The backbone of the ladder or DNA is made of the deoxyribose sugar and the phosphate group whereas the nitrogenous bases are arranged inside the DNA.
Thus, option-D is the correct answer.
