Answer:
Move from observing the most specific traits that can divide the organisms to the most obvious traits, offering 2 choices each time
Explanation:
dichotomous key reffers to a tool that give room to the user in determining the identity of items in the natural world. Items can be mammals, fish,wildflowers, mammals and reptiles. The particular key is made up of series of choices that help user to get the name of a particular item correctly. At the end dichotomous keys always bring about two choices in a step.
In dichotomous key the user has to select a choice out which of the two statements that describes the unknown organism best, with the reference of the choice made based of moves to the next set of statements, so at the end the identity of the unknown is clarified.
Therefore, in dichotomous key it move from observing the most specific traits that can divide the organisms to the most obvious traits, offering 2 choices each time

Answer:
- Pol III binds to 3' end of primer B
- Poll III moves to 5' to 3',adding DNA nucleotides to primer B
- Pol I binds to 5' end primer A
- Pol I replaces primer A with DNA
- DNA ligase links fragments A and B
Explanation:
Both strands of parental DNA acts as a template for the synthesis of new DNA. The site of synthesis is called replication fork because the daughter strands look similar to <em>two-pronged fork.</em> The strands formed from Okazaki fragments(short sequences of DNA nucleotides) is called the <u>lagging strands,</u> which is synthesized in short fragments and in the opposite direction. While the strand that is synthesized continuously and in the same direction as the movement of the replication fork is called the <u>leading strand.</u> Both strands are synthesized in a 5'→3' direction. DNA ligase join these fragments together.
Let's count them!
the initial number of zebras, let's call it z:
A population of zebras experienced ten births
this means:
z+10
six deaths to predation
this means:
z+10-6
three deaths to disease
this means:
z+10-6-3
three individuals joining the population
this means:
z+10-6-3+3
and
zero
individuals leaving
this means:
z+10-6-3+3+0
now, let's sum it up:
z+10-6-3+3+0=z+10-6-3+3=z+10-6=z+4
so the population grew (by 4 individuals); it's a positive population growth!
