Answer:
In Eukaryotes, The DNA is so long that it needs to be super coiled to get fit inside the cell.
This process is required in both Eukaryotes and prokayotes. The super coiling and packaging using the DNA binding proteins allows the lengthy molecules to fit inside the cell.
The DNA in the bacterial cell is arranged in several super coiled forms. The over winding of DNA is prevented in bacterial cell by the help of an enzyme known as DNA gyrase which is a type of topoisomerase.
Answer:
No, glucose and sucrose are not complex substances. Both are simple substances. Complex molecules are polysaccharides such as glycogen and starch.
Explanation:
Glucose is made of one sugar atom and known as monosaccharide, while sucrose is composed of two sugar atoms i. e. glucose and fructose. So that's why glucose and sucrose are not complex molecules.
B is the answer. Dry raisins swell up because they undergo Endosmosis. When a rasin is put in water then the water passes through the semipermeable membrane
Answer:
2kg
Explanation:
Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.
Answer:
In 1884, Hans Christian Gram described a method of staining bacterial cells while not staining surrounding animal tissues. However, he thought that the staining method he developed was faulty because not all bacteria stained. ... Not all bacteria stained because some have walls that prevents the staining.
