How is the absolute value of velocity speed?
Velocity is a vector and its magnitude depends on the direction. If it is positive in one direction, going in the opposite direction it is negative. But speed is a scalar and does not depend on the direction. It has the same value, whatever the direction. That is how the absolute value of velocity is speed.
If a vector has constant direction then?
There is almost never an "IF". All non-zero vectors have a constant, specified direction. Only a zero-vector has a direction which is unspecified.
What way is vertical?
Vertical is a relative term. It usually refers to a direction pointing in the opposite direction of Gravity. So if you are in outer space, then I guess there is no real "vertical" direction.
Which direction do you measure an angle?
Unfortunately there is no consistent direction: it depends on the context. If dealing with bearings (eg navigation) North is 000 degrees and the angle is measured in the clockwise direction starting from the Northward direction. In the context of coordinate geometry, particularly if working with polar coordinates, angles are measured in the anti-clockwise direction, starting with the x-axis (pointing East) as 0 degrees. Generally speaking, though, angles may be measured in any direction.
Applications of vectors?
vectors help in determining the direction . they give the magnitude of the number as well as the direction of the quantity
Where is the chromosome located within the eukaryote cell?
In eukaryotic cells chromosomes are found within the nucleus. The only exception to this is during mitosis (i.e. cell division) when the nuclear membrane disappears and the chromosomes line up at the metaphase plate and then move towards opposite direction in anaphase. Reaching the telophase these are again surrounded by the nuclear envelop.

Where does replication of the two DNA strands takes place?
in a direction opposite to that of the replication fork
Why do chromosomes assort independently?
Chromosomes have no direction in how they assort other than that they align in homologous pairs. The individual genes are part of the chromosomes and go wherever the chromosome goes just like the motors of cars go wherever the car goes.
During mitosis why do the chromosomes condense before they start moving around the cell?
so that they can be replicated into sister chromatids and then split apart in anaphase
Is RNA polymerase used in both leading and lagging strands of DNA replication?
the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction
Why do chromosomes line up in the middle of the cell during metaphase?
It is important that chromosomes move during mitosis because the chromosomes' sister chromatids need to separate. They must separate to become daughter cell-carrying chromosomes themselves.
In what direction does a DNA molecule split during replication?
In both directions.
What results if a fragment of a chromosome breaks off and then reattaches to the original chromosome at the same place but in the reverse direction?
an inversion.
What is it called when a fragment of a chromosome breaks off and then reattaches to the original chromosome at the same place but in the reverse direction?
an inversion
Why does DNA replication have to be in an anti-parallel direction?
DNA polymerase III can only work in the 5' to 3' direction.
What is the name of the strand that replicates in a direction toward the replication fork?
Lagging strand.
