DNA replication
After the process of DNA replication occurs, each daughter cell receives an exact copy of the parent cell's DNA.
DNA replication is a biological process by which a DNA molecule divides to produce two copies of itself during cell division. DNA replication takes place in all living organisms. During DNA replication, an enzyme known as helicase separates the double helix structure of the DNA molecule into two separate strands which serve as templates for making the new strands of DNA.
Population density =number of individual divided land area
land area should be in square kilometers
therefore 120 ha =120 x0.01=1.2 square kilometer since 1 ha=0.01 kilometer square
total population= (80 x 1500)/100=1200
population density is therefore=1200/1.2=1000
Answer:
It's changeable
Before the microscope, Linnaeus classified organisms only separated in two kingdoms, while more were introduced later. So, they were only classified in two kingdoms, they can be changed and classified to more than two.
Answer:
The nitrogen cycle is a repeating cycle of processes during which nitrogen moves through both living and non-living things: the atmosphere, soil, water, plants, animals and bacteria. In order to move through the different parts of the cycle, nitrogen must change forms.
When the upper water layers warm in the summer months, they become separated from deep water by a transition zone known as a thermocline. In a thermocline, the temperature decreases rapidly with small increases in depth. This phenomenon linking temperature change with depth is called temperature stratification.
