Answer;
-Down the concentration gradients; evenly distributed
Diffusing molecules move down the concentration gradients until they are evenly distributed.
Explanation;
Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.
-Whenever a substance exists in greater concentration on one side of a semipermeable membrane, such as cell membranes, any substance that can move down its concentration gradient across the membrane will do so. If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport.
-The mechanism of molecules moving across a cell membrane from the side where they are more concentrated to the side where they are less concentrated is a form of passive transport called simple diffusion.

Complete question:
Molecule 1 has the nitrogenous base sequence TCA AGT. Which set of bases in Molecule 2 can bond to that sequence in a complementary way?
a. UCAAGU
B. AGTACA
C. AGUUCA
D. UCAATA
Answer:
C. AGUUCA
Explanation:
DNA template strand and the corresponding RNA have complementary sequences. Adenine in the DNA template strand pairs with "uracil" base of RNA while cytosine pairs with its "guanine" base. Similarly, thymine base in DNA template strand pairs with "adenine" base in the RNA. This occurs since RNA does not have a thymine base. RNA has uracil base instead. Therefore, the molecule 1 with sequence TCA AGT would bind to the molecule 2 with the " AGU UCA" sequence.
Molecule 1: DNA template: TCA AGT
Molecule 2: mRNA: AGUUCA
