mass of one liter of water= 1kg
Archimedes says:
F= m g = 1 kg* 9.81 m/s^2 = 9.81 newtons
The <span>researchers </span>might not get accurate results because of the following points:
1) The students may lie about the drug use.
2) The students may write correct information and might later feel guilty of writing the truth.

Answer:
b) Cells will pass through the G1/S checkpoint even if conditions are not ideal for cell division.
Explanation:
In the given problem, if there exists a gain-of-function mutation for the given cell, there would not be the formation of cyclin E when there is the possibility of cells movement via the checkpoint of the G1/S, even when there are non-deal conditions for the division of cell. Thus, the correct option in the lists of options is the option b.
Answer:
Explanation:
Coordinate system is one that describe the location of an object in a given plane. It implies the use of axes (coordinates) and points.
Given that the man in the question walks 400 m due north of east. The cardinal points can be used in this case, with the north and east cardinals as the required axis.
scale = 
= 
= 
scale = 1:40
This is a reduced scale which implies that 1 cm on the drawing is equal to 40 m on the original length.
The man's direction is 
north of east.
The graphical drawing of the vector is herewith attached to this answer.
