Plants and trees use photosynthesis
Answer:
Option (A) and (C).
Explanation:
Gene regulatory mechanism are important for the regulation of the transcription and proper expression of genes. Different regulatory mechanisms are present in prokaryotes and eukaryotes.
The prokaryotes do not require the multiple general transcription factors where as the eukaryotes have different transcription factors like TFIID, TFIIH and TFIIA. The DNA is packed around the histone protein that form chromatin in eukaryotes. The chromatin packaging includes methylation, ribosylation with the help of enhancers and silencors. The chromatin is absent in case of prokaryotes.
Thus, the correct answer is Option (A) and (C).
Answer:
'gonadotrophin releasing hormone' (GnRH)
Explanation:
<span>d cellulose
</span>Polysaccharide are the complex form of carbohydrates.
A starch molecule is formed when many disaccharide molecules are combined. Starch is often produced in plants as a means of storing energy. The two other molecules formed when multiple disaccharide molecules are combined are cellulose and glycogen. The cell walls in plants are made up of cellulose. Glycogen is a carbohydrate energy source.
A disaccharide molecule is formed when two monosaccharide molecules are joined together. Maltose, sucrose and lactose are the most important disaccharides. <span>A monosaccharide molecule is a simple sugar, for example, glucose. </span>
