Answer:
The nitrogenous bases guanine and adenine are A. purines.
Explanation:
Adenine and guanine are purines, whereas the other two bases in DNA (thymine and cytosine) are pyrimidines. The main difference between purines and pyrimidines is the number of rings that the base has: purines have two rings while pyrimidines only have one ring.
In addition, phosphate group and sugar group cannot be the answer to this question because these two elements in addition to a nitrogenous base makes up a nucleotide.

Answer:
A group of similar cells that serve the same purpose.
Explanation:
a group of the same cells makes a tissue.
Explanation:
By definition, inhibitors slow down chemical reactions. So if you were to add an inhibitor to a reaction, you would cause the rate of reaction to decrease. The opposite idea of inhibitors are enzymes. These speed up chemical reactions, thus increasing the reaction rate
Derives from the fact that bacteria are exploited by humans in a number of beneficial ways
Answer:
<u>Peroxisome</u> is not the part of endomembrane system
(<u>Mitochondria</u> and <u>Chloroplasts</u> are also not included in the endomembrane system)
Explanation:.
The endomembrane system is composed of the different membranes which are suspended in the cytoplasm within a eukaryotic cell. They include :
1) Nuclear membrane
2) Endoplasmic reticulum
3)Golgi apparatus
4) Lysosomes
5) Vesicles
6) Endosomes
These membranes divide the cell into functional and structural components.
<u>Peroxisomes</u> are also covered with membranes but they are not considered as the part of endomembrane system as <u>they don't recieve vesicles from Golgi apparatus.</u>
Similarly the membranes of mitochondira and the chloroplasts also are not included in the endomembrane system because their functions are not coordinated with the organelles involved in the endomembrane system.
