Which of the following statements about DNA replication in E. coli is true? Which of the following statements about DNA replicat
Bond [772]

Answer:

Replication proceeds in both directions from a single origin of replication.

Explanation:

The origin of replication is the DNA sequence where the process of DNA replication begins. Prokaryotes such as <em>E. coli</em>, mostly have smaller genome sizes as compared to the eukaryotes and have a single origin of replication. The DNA helicases serve to unwind the DNA at the origin of replication and create replication forks.

The origin of replication is an AT-rich sequence where DNA is easily denatured to produce single strand bubbles or the replication loops. Both the separated DNA strands are replicated simultaneously. The replication is bidirectional which means that both ends of the separated DNA loop have active replication forks. The process of DNA replication continues until both the replication forks meet to replicate the complete DNA.

Generally, animals cannot digest (hydrolyze) the glycosidic linkages between the glucose molecules in cellulose. How then do cow
Dovator [93]

Answer:

B. Microorganisms in their digestive tracts hydrolyze the cellulose to individual glucose units.

Explanation:

Cows are ruminants.  They lack the cellulose digesting enzymes. However, they have a stomach with four chambers. The first two chambers of their stomach house symbiotic bacteria and protists. These microbes have the ability to digest cellulose into simple sugars. These simple sugars are then used by the host and the bacteria themselves. The microbes digesting the cellulose produce the enzyme cellulase and breakdown cellulose anaerobically.

Why the solute can't move from higher concentration to lower concentration?
Basile [38]

Answer:

yes, so when the concentration of a solute is high, the concentration of water is lowered since there is more solute per water, less water per solute. Thus, when water moves from low concentrations of solute to high concentrations of solute, it moves from high concentrations of water to low concentrations of water.
