Answer:
Chromosomes contain very large genetic information which would take many hours to replicate with only one origin.
Explanation:
Human cells are eukaryotes, meaning that the genetic information is compressed in chromosomes, that at the same time are contained in the nucleus. As the replication requires all the genetic information to be copied, the length of it would take several hours to complete this task. Therefore, with many origins of replication, this process happens faster and more effectively.
Answer:
Through an anchor
Explanation;
-Protein Ras associates with the membranes through an anchor.
-Ras proteins are molecular switches that decide if and when cells divide inside our bodies, thus an impairment of their function may result in the formation of a tumor or cancer.
-Ras proteins require membrane association in order to be biologically active. Membrane anchorage of Ras proteins in the inner leaf- let of the plasma membrane is an important factor in their signaling and oncogenic potential.
Fructose

Galactose
There are 3 main processes in urine formation. These are Filtration, reabsorption and secretion.
Filtration
Blood enters the afferent arteriole and goes to glomerulus where blood is filtered and it will sip inside the glomerulus and nonfilterable components will go into efferent arteriole.
Reabsoprtion
Molecules and ions will be reabsrobed into the system. The fluid will pass into the proximal, distal and convoluted tubules, loop of henle, as water an ions are removed as the fluid osmolarty changes. Last is secretion of substance that is not filtered.
Answer: The second factor that leads to fluidity is the nature of the phospholipids themselves. In their saturated form, the fatty acids in phospholipid tails are saturated with bound hydrogen atoms; there are no double bonds between adjacent carbon atoms. This results in tails that are relatively straight
